"vent"

The Stove and Fire Vent is the ideal interior vent to compliment a log burner or stove. The cast iron body is available in a polished pewter effect, which has been hand finished by us in our workshop or can be purchased bare metal for contractors or property owners to finish on site. The pewter finish stove vent will enhance any interiors. When the 100mm spigot is connected to an air source it provides 3000mm2 of free area for combustion air for a room fitted with a log burner or stove up to 10KW. Double up for larger appliances.

MEDITE VENT and SMARTPLY PROPASSIV proved to be a winning combination for the first oak frame Passivhaus to be built in the heart of Wiltshire, South West England.Built by award-winning construction company Erigo Developments, Seldom Seen, a private detached residence, was at the time of completion the first house in Wiltshire to meet the Passivhaus standard. It still ranks as only the eighth certified Passivhaus in the South West of England.Designed around a traditional oak frame and finished in oak cladding, the house was strategically sympathetic to its rural Area of Outstanding Natural Beauty (AONB) setting.The combination of MEDITE VENT and SMARTPLY PROPASSIV helped to achieve its Passivhaus status.Rebecca Thursby, Director of Erigo Developments commented: “At the time, there was nothing else on the market that fulfilled its role in this location. We used an oak frame to create the external envelope and then choose both MEDITE VENT and SMARTPLY PROPASSIV to achieve the level of airtightness required to meet the Passivhaus standard. We managed to get the air tightness down to 0.38 ACH @ 50 Pascals, which is very good.”To reach Passivhaus standard, a building must achieve an airtightness level of 0.6ACH (Air Change per Hour) at 50 Pascals or less. In other words, the volume of uncontrolled air leakages in 1 hour must be less than 0.6 times the overall building volume when the difference in air pressure between the indoors and outdoors is 50 Pascals. Named after French mathematician and physicist Blaise Pascal, ‘Pascals’ is the unit by which pressure is measured. In this case, it indicates the air pressure difference between inside the building and outside the building for the airtightness test. Reaching an airtightness level of 0.38 can be considered a remarkable achievement.Perfect for use in low energy buildings, MEDITE VENT is a high performance, breathable sheathing panel, suitable for use in timber frame structures. It boasts high racking strength in excess of Category 1 requirements, and high vapour permeability alongside weather resistance. Its extremely low vapour diffusion factor helps to prevent condensation and because it is manufactured with no added formaldehyde, it contributes to both a healthier working environment for installing contractors and a healthier living environment for building occupants.This intelligently formulated panel is teamed with SMARTPLY PROPASSIV, an airtight structural OSB/3 panel with integrated vapour control properties, used as structural sheathing in timber frame buildings. These features eliminate the need for additional Air and Vapour Control layer (AVCL) membranes. Its coating also provides a durable, smooth surface perfect for the use of airtight tape at the panel joints. SMARTPLY’s in-house speciality surfacing technology provides this integrated vapour barrier, which delivers high and constant vapour resistance across the whole surface.For this project, the timber frame was in-filled with Icyenene sprayfoam insulation, with SMARTPLY PROPASSIV lining the interior, alongside plasterboard facing the room. MEDITE VENT was installed on the exterior of the spray foam, which was then topped with Tyvek wrap and finished with the timber cladding.MEDITE SMARTPLY’s entire product range, including MEDITE VENT and SMARTPLY PROPASSIV, is manufactured with FSC® certified Irish timber, from their own sustainably managed forests, demonstrating a clear supply chain and manufacturing process.Being conscious of how this industry impacts the environment is also something that Erigo Developments takes very seriously. Erigo is an award-winning construction company that puts an exceptionally strong focus on being environmentally responsible. The company demonstrates this by selecting carbon responsible materials and always aiming to achieve zero non-hazardous waste to landfill in all of their projects.“We've made a commitment that we're only going to build to a Passivhaus standard going forward, and to build with carbon responsible materials,” continued Rebecca. “I think everyone needs to do their bit to combat climate change.”“I think that building regulations need to go further in terms of power requirements and what's needed from houses now to achieve energy efficiency. That way, everyone knows what they can do in order to reduce their energy demands. There also needs to be more incentives in place to make people choose carbon responsible materials.”The use of MEDITE VENT and SMARTPLY PROPASSIV provides a winning formula for sustainable building.

Here is an email we received after a client installed the conservation cowled cast iron air vents to a London property in September 2022)...We recently did a project on an old coach house in a listed building. They wanted a/c but we couldn’t route water for the h2o unit and couldn’t have two big white plastic vents on the outside of the building.The solution was to combine your products, a pair of CON6 cast iron conservation vents. The clients are ecstatic. I thought I’d share as I’m sure a lot more people in old houses will be looking for a/c going forward.Sally Estad, Elstad Interiors, Chicago USA ( working on a property in Wimbledon, UK)

Originally used during Victorian and Edwardian period as sewer vents or "stench flaps", these cast iron vents with 100mm round spigots are making a bit of a come back. We've replaced the flaps (that used to allow air in but not out) with mesh so air flows freely in both directions and they've become quite a hit with specifiers ventilating basements and cellars and new builds. As well as sending a shipment to Abu Dhabi we've also had orders from closer to home - Travis Perkins, Midas, Bryen & Langley and 800 Group

Almost ten years since introducing the CON4 100mm conservation we are now adding to our collection of conservation vents with the CON6 which is our biggest yet. With a massive 150mm diameter spigot and a free area that is 50% larger than the next size down, it's sure to be a hit with many property restorers looking to add plenty of ventilation with a stunning looking vent that will last a lifetime.

Ninety UDF-50 REM Bilco Natural Smoke and Heat Ventilators (NSHEVs) were installed in a large scale accommodation development at the University of Hertfordshire. The development at the College Lane Campus comprises a mixture of individual bedrooms, twin rooms and studios. All of Bilco’s NSHEV products are manufactured to the highest possible standards, are CE Marked and meet Construction Products Regulation 305/2011. At 1500mm x 1620mm Bilco’s double leaf UDF-50 REM Smoke Vents offer a 1.5m2 clear vent area – making them ideal for dwellings of multiple occupancy such as halls of residence.

Bilco UK’s special zinc-clad Roof Access Hatches and Smoke Vents chosen for the Zaha Hadid designed Glasgow Transport Museum, Scotland. The roof specification included Smoke Vents and Roof Access to blend with the roof finish. Bilco supplied modified units with zinc cladding to achieve the desired look. To enable safe roof maintenance, a modified E-50T Hatch was supplied and installed to the 46 degree sloping roof enabling maintenance staff to gain easy, safe access to roof equipment

Take one look at our website and customers would be forgiven for thinking our grilles are only available painted in one colour - black. They can of course be supplied bare metal to go rusty in many cases as another option but black is our standard colour. That said we supply vents and air bricks painted in a huge range of RAL colours. These cant be ordered direct from the website and there is an additional cost but they can be turned around in a week or so. Please email for more details

Designed by The Cast Iron Air Brick Company, this stunning grille was transformed from a concept to "a work of art" by North Devon based, pattern maker, Peter Hoole in 2010 and is now cast in West Midlands. With over 2000 sold, its fast becoming "the" conservation vent for listed and period properties and is now available with a 5" diameter(125mm) spigot as well as the original 4" diameter (100mm). Supplied in traditional black or primed for contractors to colour co-ordinate to owners requirements on site.

Three MEDITE MDF products MEDITE TRICOYA EXTREME, MEDITE VENT and MEDITE MR are being specified for a new line of garden buildings.

There are a lot of different official documents about the rules and regulation around fire safety and smoke ventilation, which, in turn, influence the way you should choose and install your AOVs. Building regulations are minimum standards that apply to almost all new residential and commercial buildings, and also alterations to the existing ones. If you are planning to use an Automatic Opening Smoke Vent (AOV) System in your project, you will have to comply with the regulations mentioned.

AOV or Automatic Opening Vent systems control the airflow of smoke in a fire. According to EN12102-2 it is a statutory requirement to have an AOV unit on a new construction. Since 2006, Europe has required that the AOVs meet with the standards set forth in DIN EN12102-2. As a result, many companies have made their versions of AOVs. Majority of these options only go as far as barely meeting the before stated regulations. However, the Coxdome Firejet SHEV exceeds the expectations and requirements of a standard AOV.

Project: London Architectural Glazed approached Surespan to design and manufacture bespoke roof access and AOV Hatch. The project had a requirement for a huge 4700 x 1300 Smoke vent with access however due to EN12101-2 testing, Surespan only has CE Certification up to 1800 x 3000mm. Surespan designed a solution which involved combining a large 3628 x 1300 electric roof hatch with a separate 1300 x 1218mm SRHE/AOV unit combined into one frame.

The data sets for SIEGENIA's ventilation units can now be found in the CAD/CAE software Trimble Nova. This enables architects and planners to carry out easy and reliable planning with the facade and wall-mounted ventilator data as well as components contained in the software.

Product:140° degree opening glazed smoke ventilation up to 3m x 1.2m. Here installed and commissioned in a newly upgraded prestigious London address. CE Marked and Certified to EN 12101-2. The AOV features concealed actuators along with a double-glazed top. 1.5 W/m²K Double Glazed Lid Custom made to any size up to 3m x 1.9m

Glasgow’s latest redevelopment project, located on Langside Road, is built upon the former site of the city’s Victoria Infirmary and consists of a large housing development that includes 413 flats, offices and retail space. The 3.75 hectare site, which is situated next to Queen’s Park on the south side of the city, forms an important part of the Battlefield area’s character, with the buildings’ exterior reflecting and complementing the surrounding heritage by using the city's traditional blonde coloured sandstone.  As part of the construction process, Bilco UK was commissioned to supply six ESW-50REM Smoke Vents, in addition to seven E-50TB Roof Access Hatches, to provide the highest standards of safety and efficiency, whilst being sympathetic to the project’s overall design.  Installed onto the roof areas of four blocks of flats by Scottish contractors, Procladd Small Works Ltd, Bilco UK’s ESW-50REM Smoke Vents were specified to provide essential ventilation in the event of a building fire. Featuring a linear actuator operating mechanism that opens the cover to 140 degrees within 60 seconds, the smoke vents ensure compliance with Building Regulations Approved Document B, BS9999 and EN12101-2.  The built-in wind deflector also provides protection against smoke being blown back into the vent in the event of a fire., whilst the newly-designed closed-cell EPDM sponge gasket helps meet Building Regulation air leakage targets by providing a better seal of the cover to the curb. With the addition of a fixed vertical ladder, the smoke vents can also be used by maintenance engineers for roof access.  Billy Baillie, Managing Director at Procladd Small Works Ltd, said: “We have a longstanding relationship of over 20 years with Bilco UK, and will continue to do so over the forthcoming years, due to their impressive product quality and outstanding service. Bilco UK’s Roof Access Hatches and Smoke Vents were incredibly easy to install, and knowing they’re engineered to meet the highest industry standards, it provided both ourselves and the client with the confidence that the installation would set the standard for performance and longevity.” Constructed with corrosion-resistant materials, Bilco UK’s E-50TB Roof Access Hatches were also installed to provide engineers with safe, regular and convenient access to the roof to conduct essential maintenance. Engineered with compression spring operators to provide easy one-hand operation, the roof access hatch meets the requirements of Manual Handling Regulations, whilst the automatic hold-open arm locks the cover in the open position to ensure safe egress. The overlapping cover design, fully welded corners and insulated cover also ensure weathertightness and energy efficiency to deliver the highest standards of resilience. Mark Baird, Sales Operations Manager at Bilco UK, said: “Drawing on our longstanding relationship with Procladd Small Works Ltd, it was fantastic to work together on this project, which has been designed to positively impact the city’s culture. The products installed were manufactured with fire safety and efficiency in mind, delivering assurance of the durability and suitability of the installation for years to come.”For further information on Bilco UK’s complete range of roof access solutions, visit www.bilcouk.co.uk or call 01284 701696. 

Project: Creative Centre, York St John UniversityClient: Tate+Co ArchitectsScope of project: Design and supply 24 bespoke-sized rooflights for the roof of a triple-height atrium to fit within apertures in a glulam timber grid.Products: 24 bespoke sized em.glaze rooflights, some with concealed actuator smoke ventsThe ChallengeThe roof of the striking 14m, triple-height atrium, which forms the centrepiece of the newly opened Creative Centre at York St John University, features a glulam timber roof grid. Architects Tate+Co wanted to punctuate that grid with bespoke sized rooflights to bring even more light into a space which is used as an exhibition, teaching and theatre space, as well as somewhere for students to mix and relax. The rooflights had to have a sleek, minimalist aesthetic, in line with the overall design intent of the atrium and, because almost all the services in the atrium are hidden, needed to be available with matching concealed actuator smoke vents.The SolutionWhitesales designed and supplied 24 bespoke-sized em.glaze rooflights which suited the specification perfectly. The flush-glazed glass-to-edge design of the em.glaze units with flat sealed glass units fitted within a fully welded, thermally broken aluminium frame achieved the lean, crisp look the architects were looking for. The fact that they were also available with fully concealed actuators in the smoke vents supplied by our affiliate business Sertus was an added bonus. All the rooflights were supplied for the project complete with preformed 300mm PVC splayed upstands, which enabled them to be fitted directly into the glulam grid, saving the contractors time on site. They were also fitted with specially coated glazing which allowed for a degree of solar gain and contributing to the low energy requirements of the BREEAM Excellent rated building.‍The BenefitsAs well as the meeting the design specification, Whitesales’ technical team helped to ensure that the em.glaze rooflights could be installed quickly and efficiently by the main contractors Kier Construction. We estimate that our recommendation to supply the units with preformed 300mm PVC splayed upstands saved the roofing team at least two weeks on site because they didn’t have to construct the upstands themselves and the integrated splay made waterproofing the roof a lot easier. Tate+Co Director Andy Baker-Falkner is delighted with the em.glaze units: “We liked the lean, crisp design of the Whitesales em.glaze units, particularly with the clean white reveal and option for fully concealed vent actuators.”

Design & Build construction of a purpose build student accommodation development to provide 1,025 bedrooms and once completed it will provide a dramatic new addition to the Birmingham skyline.The buildings comprise of two bold, angular towers with sharply defined ‘razor’ edges and a smooth, highly detailed, gloss black finish, rising 13 and 24 storeys respectively. The towers are anchored by a middle section rising to 10 storeys and finished with a traditional, matt brick with defined window reveals and texture.The building is designed to achieve a BREEAM Excellent rating and the student beds arranged principally in cluster units.Noise absorbing window ventsDucoMax SR is a self-regulating, acoustic vent (sound attenuating ventilator), specifically engineered for situations exposed to high levels of noise disturbance. The various types are attractively designed and offer excellent acoustic and airflow performance. Suited to high-rise applications, the SkyMax variant was also placed in this project. The SkyMax SR is an upgraded version of the DucoMax SR making it applicable to heights up to 70 meter. The acoustic vents ensure that the students have a carefree night's sleep in a bustling city. 

The 110m, 29-storey curved on plan Westmark Tower is the tallest residential tower to have been completed in central London in 2021. Part of Berkeley Homes Central London’s prestigious West End Gate development in Marylebone, it features more than 14,000m2 of unitised curtain wall designed and supplied by aluminium fenestration specialists AluK and installed by envelope contractors Martifer. What makes this project really stand out is the collaborative approach that was demonstrated by AluK and the other consultants involved from the outset. With Berkeley at the centre of the process, the technical and commercial elements of the façade were successfully de-risked at pre-tender stage because AluK was able to work directly with lead architect Squire & Partners, delivery architect Design Delivery Unit (DDU), façade consultants Cladtech Associates and structural engineers WSP on a RIBA 4 system design for the unitised envelope. The challenge for AluK was to work with DDU to deliver a design that was true to the architect’s original intent whilst addressing the technical issues of a curved on plan façade from the second to 29th floor. All the united cells needed to be dead loaded back to a post tensioned concrete frame with a 3-dimensional floor bracket, whilst catering for the varying facets of the façade.The final unitised solution features more than 2200 unitised cells of three principal configurations. Each floor comprises: a vision cell, typically housing AluK’s concealed vent and full height glass panes, a panel cell, specifically designed to house specialist internal framework to carry articulated GRC (Glass Reinforced Concrete) feature piers and spandrels, and a recessed balcony cell with an integrated floating glass balustrade.With 36 different angles to overcome in a faceted design ranging from 0° to 15°, AluK developed a series of common aluminium extrusions to close the joints and reduce the number of profiles required. The horizontal stack joint uses an aluminium profile to carry the gasket and avoid the incidence of crimping as the cells are stacked around the building structure. What is also significant is that every cell connection provides four lines of system seal to ensure that the façade meets the stringent Cladtech performance specification and the CWCT Sequence B test.AluK’s system, extruded from 6063 T6 alloy, extracted benefits from both a mitred corner and a square cut system by creating a hybrid to suit both the client’s aesthetic desire for a mitred joint to the corners and Martifer’s manufacturing requirements of a square cut for economy.AluK also extruded tailored aluminium bracketry from a structural 6082 T6 alloy which was capable of supporting the system weight and allowing for 3-dimensional adjustment for precise installation.From the onset of the project, the Berkeley director team set out a time and design model of early engagement, specialist designers and fabricators all within a clear programme. This also included a series of productive workshops sharing client expectations and considerations. AluK not only facilitated these meetings but also bought into the collaborative ethos and contributed to a highly successful project for Berkeley.AluK’s designers are all from a fabrication/installation background and, as such, they design a value engineered solution from the outset. Part of this was using 14,000m2 of AluK’s AW86 unitised curtain walling system with minimal bespoke profiles and gaskets, yet it meets every challenge the project presented whilst offering a significant cost reduction in metal and accessories compared to the original specification in a competitor’s system. As part of the project team, AluK worked collaboratively alongside consultants Squire & Partners (concept architect), Buro Happold (thermal and acoustics), WSP (structures), Design Delivery Unit (delivery architect) and Cladtech (façade consultant). The façade design meets the thermal efficiency requirements of the building at 0.95W/m2K, as a weighted average. Using a 43dB Rw(+Ctr) acoustic glass, it also meets the sound reduction targets. Because AluK was involved at such an early stage in the project, the complete RIBA Stage 4 system design enabled façade contractors Martifer to realise significant cost savings for their tender and several months of time saving against their usual post-tender design and iteration phase. This also offered cost certainty for Berkeley and significantly de-risked the post tender delivery of the façade.Alongside the unitised curtain walling, the finished Westmark Tower will feature 241 AluK SC156 lift and slide doors, 750 concealed vents and 58 swing doors.West End Gate is Berkeley Homes’ latest luxury development being built on a 2.66-acre site. Described as a modern interpretation of classic London, it will feature a series of contemporary mansion blocks alongside the 29-storey curved stone tower. Work began on the first phase of West End Gate in the Spring of 2018 and was completed in Spring 2021, with internal fit out nearing the end.

Before there was an open, 4" (100mm) diameter pipe that drained water from the back of this Devon farm house into the yard. Apart from an open pipe, which never looks good on a listed building, when it rained heavily there was water gushing out across the road causing havoc to any cars parked nearby. With the installation of the cast iron cowled conservation vent now the water is deflected downwards and the opening is no longer open to the elements and in eye line. With a choice of 100mm or 125mm spigots this cowled vent has many uses

Copenhagen’s Amager Bakke is a visionary project in Denmark that doubles as a recreational playground and a waste-to-energy plant.The towering structure is over 280 feet high, has an estimated cost of $670 million and is a part Copenhagen’s commitment to become the world’s first carbon-neutral capital by 2025. Part of the facility is already on line.The waste-to-energy plant, a giant incinerator that burns household garbage to generate heat for approximately 160,000 households and electricity for 62,500 homes, began operating in March. The recreational component is still under construction.Kalwall® translucent sandwich panels provided a critical solution in this truly global project, with their aesthetic beauty, energy efficiency and, most importantly, their best-in-class explosion-venting properties.Kalwall panels are used in areas of the building where a potentially volatile event could occur. The panels work to vent pressure out of the building, allowing it to withstand an explosion without collapsing roofs or floors. The panels are designed to release from their mounting system, but remain attached to the side of the building to avoid becoming falling debris. The interior of the panels are shatterproof and include a Fiber-Reinforced Polymer(FRP) face sheet that can be customied to withstand 230 ft-lbs (312J) of impact.Staying close to the project’s mission of being environmentally conscious, Kalwall panels provide dramatic savings in energy consumption through exceptional thermal and daylighting performance that reduces heating costs and artificial light usage.Working through Sipral, a leading supplier of external building envelopes based out of Prague, the panels were delivered on schedule and required no on-site modifications. Amager Baake was designed by the highly-acclaimed architecture firm Bjarke Ingels Group (BIG) and has the world watching as it merges two completely different applications.BIG founder Bjarke Ingels hopes that Amager Bakke will “change public perceptions of what a public utility should be” by providing a social and physical infrastructure.Amager Bakke provides Copenhagen with a rooftop ski slope that is comprised of 1,600 feet of trails, as well as 10 running and walking trails. There is also a 260-foot climbing wall along the facade.Ingels said the concept of a structure that brings together two diverse interests can be lasting. “If you make a building that remains relevant to the people living around it, and using it and inhabiting it, it can last forever,” Ingels said in an interview with CNN Style.Photography: Christoffer Regild

Sudbury House is a building that was identified shortly after the Grenfell tragedy as having flammable cladding and inadequate smoke ventilation. Sertus Façade Louvre Blade smoke vent windows and Sertus control panels were identified as the best fit. Fully certified to EN standards, these attractive windows open to 90 degrees in under 60 seconds when triggered, and are designed for installation into facade apertures or curtain walling. Louvres were also fitted to the head and entrance levels of the stair cores, a single leaf vent installed in the lobby. Finally, firefighter’s priority switches were installed on every level.

Tiny Houses are on trend. Downsizing, sustainability and the desire for affordable housing are the three most important reasons why miniature houses are rapidly gaining in popularity in Germany. More than one tenth of single people considering home ownership are currently interested in this kind of Tiny House - according to the "Livee Tiny House market study 2021". And you don't have to go without your home comforts. The Tiny House with solutions from SIEGENIA proves this.Save precious spaceWith this well-thought-out use of just 16.5 square metres of floor space, the solutions from SIEGENIA have made a significant contribution to the favourable response to the Tiny House. For example, the sliding hardware, ECO SLIDE, saves valuable space behind the sofa because the window sashes do not swing open and closed but slide to the side instead. Every centimetre of living space can therefore be used. Room comfort solutions from SIEGENIA are also installed in the remaining windows. Here the tried and tested TITAN fittings provide smooth operation and ease of use. As TITAN vent secure, it combines this in the bathroom with efficient burger resistance in accordance with resistance class RC2, even in the tilted position. Whereas in the loft, it demonstrates its versatility as hardware for an especially narrow, elongated element.And finally in the kitchen area, the AEROPAC wall-mounted vent unit guarantees demand-based ventilation even when you are out and about. The ventilator with its elegant design not only operates incredibly quietly, it is also equipped with sound absorption, which provides a quiet home in noisy environments.

We adapted our aluminium window specification to meet the narrower than normal vent dimensions at the best-in-class £52 million student village in Coventry, balancing requirements for daylighting, ventilation, student safety and aesthetics. A total of 3,500 sqm of aluminium windows together with aluminium curtain walling and aluminium high-traffic doors were fitted at the 893 home development. The installation not only contributed to the creation of an uninterrupted, zero combustible facade, but also provided maintenance solution for the building owner. Paradise Street has been architecturally inspired by the originally medieval city of Coventry. The scheme's homes are arranged in a wall, and three towers to address the busy ring road, with a gatehouse opening into a 2,000 sqm piazza. Balancing the ventilation and necessary daylighting requirements led to the introduction of a fixed and opening vent to each room. This presented a whole new design challenge when it came to the window detailing, hailing a true example of design and technical collaboration between the architect, contractor, fabricator and TECHNAL. Complementing the subtle textures used for the facade's anodised aluminium panelling as well as the interior colour scheme, the TECHNAL systems are dual colour. Externally they are finished in pearl beige and white, internally. Other TECHNAL systems used for this project include the visible grid curtain walling. This is installed into an angled brickwork detail, creating an interesting wedge shape design to the common room space. To the main entrance, TECHNAL high traffic aluminium doors have been installed and tested to Secured by Design standards. These feature maglocks and automatic gearing that are tied into the building management system, ensuring all doors open in the event of an evacuation.

Nuplace are a quality lettings company, owned by Telford & Wrekin Council. It secured planning permission to build 39 new homes on a site in Telford. The window specification was for a White chamfered profile that could achieve an overall U value of 1.4 W/m2K. SBD accreditation was a requirement AND PAS24. The site’s location near a busy road meant acoustic glazing was required on some elevations. Trickle vents were required on some windows, including those with acoustic glazing requirements, which meant non-standard acoustic trickle vents were required.

OverviewMechanical Smoke ventilation system designed and installed by Dyers Environmental Controls Ltd at Droylsden Marina.Project BackgroundThe Wharf, set alongside Droylsden Marina offers a collection of modern 1, 2 and 3 bedroom apartments which required a mechanical smoke ventilation system. Dyer Environmental Controls Ltd supplied and installed a mechanical smoke ventilation solution in a Watkin Jones Homes development. The fully automatic EN certified system allows safe escape for residents and clear access for firefighters.Project SolutionDyer Environmental Controls Ltd supplied and installed a mechanical smoke ventilation solution in a Watkin Jones Homes development. The apartment block has 6 levels connected by a central staircase. Dyers installed EN certified dampers to each floor along with local smoke detection. The fans were placed within the smoke shaft with a Powrmatic N-SHEV Roof Opensky louvred ventilator situated above them, providing weather protection. A control panel operates the duty and standby fans. Two AOV smoke dome vents are in place to provide smoke clearance, one located on level 6 and the other on the central staircase.Project ResultThe Powrmatic open sky louvre is situated above the smoke extract fans, providing weather protection. If smoke is detected in the building the system will open the corridor AOV, smoke shaft damper, head of stair vent and open sky louvre. The duty fan will run to extract any smoke located in the corridor. In the event of a power failure the standby fan will engage. Dyer’s fully automatic system allows safe escape for residents and clear access for firefighters.

OverviewHead of stairwell High Rise Student Accommodation Ventilation designed and installed by ADS (Air Design Systems) at a brand new student accommodation on Friars Road, Coventry.Project BackgroundTrinity View is a brand-new student accommodation in Coventry with Six iconic blocks for 614 students, all set around a private courtyard which required a smoke ventilation system.Project SolutionADS (Air Design Systems)  installed Powrmatic N-SHEV Stirling natural and smoke ventilators at the head of three stairs along with Stirling vents above the smoke extract fans in two smoke shafts. Along side these smoke ventilators, a Powrmatic N-SHEV Wall Opensky was installed at the head of a separate smoke shaft that terminated in the Façade. The Stirling Casement Ventilators were operated by 24v drive open/drive close actuators opening to 90° and painted to a RAL 7016 colour to match the existing building. The Roof Opensky N-SHEV ventilator was also operated by an electric 24v drive open/drive close actuator with single skin aluminium blades mounted on a turndown base.Project ResultADS (Air Design Systems)  delivered an expectational high rise student accommodation smoke ventilation installation which was handed over on time and in budget with their customer. The student accommodation now benefits from a life safety smoke ventilation system. ADS also provided the smoke shaft dampers, the facade FLW Fieger louvred vents and the full control system for the accommodation. The 4 different sized Stirling Casement ventilators offered 1.04m² (x2) , 1.32m², and 1.15m² Free area to Approved Document B.

In the heart of the vibrant student city of Sheffield lies The Gate, a modern student accommodation scheme that houses 455 students. The imposing building is situated along the busy main road bordering Sheffield Hallam University and is equipped with numerous facilities including a gym, rooftop terrace, and a cinema… The complex is truly a diamond among student residences. The installed DucoMax sound attenuating window ventilator makes a major contribution to the healthy indoor climate of the building.About The GateIn the heart of the bustling student city of Sheffield, surrounded by a number of busy roads and right next to Sheffield Hallam University, is the brand-new student accommodation - The Gate.   Numerous facilities contribute to a pleasant living environment for the 455 students who live there, including a gym, a spacious rooftop terrace with breathtaking views, a cinema room, communal kitchens and study areas.A Healthy Indoor ClimateAt The Gate, attention is not only paid to different accommodation levels for the students, but also their long term wellbeing and as part of this a healthy indoor climate is also highly valued. On average we spend 90% of our time indoors. Good ventilation ensures a healthy home and prevents health problems such as dry eyes and throat, headaches while studying, loss of concentration and stress among the students. In addition, good ventilation has been shown to improve learning performance by up to 23%. The Gate opts for a natural ventilation system in which fresh air is supplied through the facade. The DucoMax acoustic window vent not only ensures a plentiful supply of fresh outside air, but also reduces any outside noise from the city below to a maximum (up to 53 dB).Reducing noise nuisanceThe ventilation system supplies fresh air via the DucoMax acoustic window vent in the living and sleeping areas, while in humid rooms polluted air is removed. The central location of The Gate provides easy access to the vibrant city of Sheffield, but unfortunately this can cause a lot of noise nuisance too due to the busy traffic. The DucoMax was developed specifically for buildings with high levels of noise disturbance, to keep the noise out. The integral self-regulating valve also keeps the air flow constant during differing wind pressures. As a result, students are hindered as little as possible by these external factors. The combination of the various facilities with a healthy indoor climate contributes to an optimal learning and living environment for the students.

Kawneer’s AA®100 curtain wall, AA®540 vents, and series 190 and AA®720 doors were specified by the regular Kawneer users for the latest redevelopment of the Wilfred Brown Building at the university in Greater London. The mullion-drained capped and SSG (Structurally Silicone Glazed) curtain wall forms a new sawtooth façade to the first and second floors and is complemented by the AA®540 window vents which are top-hung and also Structurally Silicone Glazed, series 190 heavy-duty doors to the main entrance, and the thermally-superior AA®720 doors.

Five new towers at the University of Brighton’s Moulsecoomb Campus are now protected by a fault-tolerant network of MxPro 5 fire panels from Advanced.The 13 networked MxPro 5 panels have been installed to protect the five student accommodation towers varying between eight and 18 storeys, which will provide more than 800 student bedrooms as well as ground-floor fitness facilities and amenities for the students’ union. Responsible for the fire system design, supply and commissioning were West Sussex-based Southern Fire Alarms (SFA) Ltd, who installed the equipment alongside mechanical and electrical engineers J&B Hopkins.The fire system is integrated with multiple third-party interfaces, including automatic opening vents (AOVs), sprinklers and access control. Careful consideration was given to the complex cause and effect programming that needed to be applied across the site. Each building is configured with a six-minute investigation period, with sounders on the floor of origin initiated after a single device activation. A single subsequent device activation will escalate into full evacuation of the specific tower. A master key switch has also been introduced, to allow for full evacuation of all towers if required.

The building comprises of 3 sections, varying in height with retail space on the ground floor and student accommodation from the 1st to 10th floor being operated by Unite Students, which runs student accommodation sites across the UK. The project utilises Aluprof MB-SR50N capped curtain walling and inward opening vents with an external mesh to prevent objects from being release at high level from inside the building.

Flymesh and cast iron air bricks, up till now, Installers have either pushed the mesh into the back of the air brick from inside - never to be cleaned again - or meshed over the air brick and held it in place with silicon - never to be removed again. Which is why we invented the cast iron flyscreen airbrick with removable copper mesh. It solved a problem faced by Galliford Try, constructing the athletes village for London 2012 Olympics when they needed feature vents for kitchen extraction to enhance their clay bricked homes.

Looking down for architectural features in any Georgian town and as well as coal hole covers, manholes and the like you'll see all manner of air bricks and grilles, mostly for sub floor ventilation in property walls. Here is an illustration of a cast iron vent underneath a front door in Regency Bath. Like many it's in a pretty poor state. This one's patched up with steel plate and it's suffocating, what is a key part of the ground floor causing damp. Prevent damp in period property basements and below suspended floors...

Crittall Corporate W20 windows are an important component in the refurbishment and upgrade of a prominent industrial site in historic Bath.Newark Works is recognised as a masterclass in the retrofitting of heritage buildings that has transformed a former riverside heavy engineering factory into 21st century workspace.The buildings, dating from 1857 to 1905, are Grade II listed and sit within Bath’s designated World Heritage Site. They were formerly the home of world-renowned crane makers Stothert & Pitt but had fallen into serious disrepair. Their location as part of a larger Bath Quays redevelopment spurred their re-use, underpinned by sensitive treatment, to create 40,000sq.ft of modern workspace.“We specified the Crittall W20 system to replace the existing, single-glazed, cast-iron framed windows that were at the end of their life and deemed beyond repair,” said Nick Brown, Director of Ferguson Mann Architects.He explained: “The Crittall W20 system was chosen due to the need to use a window system that could sympathetically reproduce the fenestration of the large industrial windows – many of which were 3.6m tall – but also provide a huge thermal improvement.”  It was recognised that retaining the original cast iron windows and introducing secondary glazing was neither economically viable nor appropriate aesthetically.“The slim profiles of the Crittall W20 system meant we didn’t have to compromise on the amazing amount of natural light coming into the interior whilst improving the air tightness and reducing the overall heat loss of the building through the windows,” said Brown.He added: “Crittall were also able to recreate the opening vent arrangement of the existing windows, meaning we could also improve the natural ventilation provision to the new workspaces.”Consulting engineers Buro Happold calculated that just replacing the existing single-glazed windows with new double-glazed alternatives with a U-value of 1.8W/m2K would result in a 16 percent annual energy saving. That translated to 21.4 tonnes of CO₂. Over the building’s lifespan of, say, 25 years, that equated to a 535-tonne reduction in CO₂ emissions.In view of the heritage credentials of the buildings, planners and conservation officers at Bath & North East Somerset Council were consulted on the desire to replace the original fenestration with like-for-like steel windows. The local authority was keen that the buildings should be brought back into use after several previous failed attempts. They wanted the site’s historic significance to be respected while avoiding the desire to turn Newark Works into a ‘museum piece’. The installation of Crittall W20 was approved and two of the original cast-iron windows have been retained and refurbished as a reminder of the original building but not in a way so as to compromise the improved thermal performance of the whole.Summing up, Nick Brown comments: “Everyone is really pleased with the final result.”
