"smoke and heat control systems"

Hatfield Place, a luxury country house wedding venue, chose Junckers solid wood flooring fitted with Leveldek underfloor heating system for its newly developed building. The new foyer, ceremony hall and wedding breakfast room overlook the original walled garden, with views of the beautiful parkland to the rear. The redeveloped building is bright and airy with large feature windows and high ceilings. In the foyer, a spacious room with seating for up to 300 guests, Junckers 22mm Oak Variation flooring provides a warm and lively backdrop, adding character with its subtle colour variations and natural grain patterns. In contrast, the ceremony hall and wedding breakfast room were fitted with Junckers’ Oak Harmony plank flooring, a wide board floorboard which gives a more uniform impression required for the formal spaces. Both floor types were pre-finished in Junckers’ popular Ultramatt lacquer, a strong and durable finish with no surface sheen. Delivered pre-finished, the floors are ready to walk on as soon as they have been installed and will withstand years of dancing and dining with the correct maintenance. The floors in all three rooms were installed over Leveldek, Junckers’ fully integrated underfloor heating and levelling system. Working in partnership with Jupiter Heating Systems, the Leveldek system was developed to simplify the specification process to offer a versatile levelling system, underfloor heating and solid hardwood floor from a single point of supply. Underfloor heating is the most efficient way of heating a large, open area. Specifying Leveldek offered Hatfield Place an all-in-one solution whereas traditionally, installation of the heating system, levelling system and the floor itself would have to be separately sourced. The system is efficient and cost effective to run, ideal for use in a large space. For energy efficiency and fast acting warm-up time, the heating pipes are installed directly beneath the floorboards and the panels are insulated and reinforced for outstanding heat output. The system can be used on an uneven substrate as varying heights can be achieved with the stacking cradles. For more than 30 years, Junckers’ wooden floors have been recognised as the only type of solid hardwood flooring on the market stable enough to be guaranteed for use over underfloor heating. Junckers offers a full guarantee for the system, which is recommended for residential and commercial buildings as well as sports and dance. The flooring contractor was PICA Floorings. 

Project BackgroundThe Harrow Club in London W10 has been creating positive futures for marginalised young people in West London since it was formed in 1883 as The Harrow Mission Church. Through general youth clubs and specialist interventions, they aim to empower young people to complete their education, avoid anti-social behaviour and become positive contributors to society. They work with up to 500 young people each week across 6 clubs, helping them to recognise their full potential.The Harrow Club with high ceilings, period windows, and exposed beams has a large sports hall which is a preserved reminder of the Club’s heritage, plus a smaller dance studio, both of which were heated by an old continuous gas-fired radiant tube system that had ‘life-expired’.Project SolutionBuilding Services Engineering Consultants, SS and A of Great Portland Street were commissioned by the Harrow Club to explore options for the replacement of the old radiant heating system. They called on the expertise of Powrmatic to review possibilities and offer a solution.The installation of the new systems was expertly undertaken by Industrial Commercial Environments Ltd of East Sussex. Radiant heating is the most suitable form of heat for both sports halls and dance studios as the lower air temperature for the same comfort level is approx. 5ºC lower than with a warm air system, thus producing a beneficial environment for the activities. A new Powrmatic SRP-PCV+ continuous gas-fired radiant tube system was the proposed solution. This enabled the installation to follow the route of the existing thus minimising costs and disruption during the works.Project ResultThe new Powrmatic SRP-PCV+ continuous radiant heating systems in the two halls have provided the Harrow Club with energy-efficient heating for the next two to three decades. These systems deliver the comfortable environment crucial for the well-being of the young people that the club nurtures in their quest to improve their futures.The Harrow Club now benefits from the energy-efficient Powrmatic SRP-PCV+ systems, listed on the Carbon Trust Energy Technology List (ETL), reducing their fuel bills, carbon emissions and thus their impact on the environment.

OverviewPowrmatic was selected to supply a frost protection warehouse heating solution for a massive 81,000m² building at Plot 2 at the Midland Logistic Park installed by Phase Mechanical Projects. a combination of 7 TE61 heating units and TE61 Destratifcation units were installed.Project BackgroundThe 81,000m² industrial logistic warehouse required frost protection with design parameters of -5°c external and +5°c internal.SolutionOne of our largest installations to date, 4 x TEG61 air rotation heaters were installed by our trusted partners Phase Mechanical Projects. Each TEG61 heaters boasts an impressive 525kW of heat output and were installed alongside 3 x TE61 destratification units to assist with the air turnover due to the size of the building. The 4 TEG61 heater units selected were designed to move 39m3/s of air around the building per unit, and when combined with 3 TE61 destratification units also at 39m3/s this gave a total air volume of 270m3/s which achieved the required 0.8 air movements per hour from the end client.ResultThe newly styled Powrmatic Air rotation units in our new RAL 7015 colour were installed expertly by Phase Mechanical Projects. The racked logistic warehouse will now benefit from a frost protection system which will protect the internal sprinkler system from freezing in the colder months. Each T.E manufactured at Powrmatic is custom built to specific project requirements.

Powrmatic was selected to supply a large distribution centre with an energy-saving air rotation heating system for ILG's 46,800m³ distribution facility in Gatwick working in partnership with Air Ability who supplied and installed just a single Powrmatic TEx41 air rotation heater.

Façade automation for failsafe natural smoke ventilation in a prestigious infrastructure project.

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.

A project to install a communal heating system at low rise flats and maisonettes at Bretton House and Sanders Way, in the London Borough of Islington, is using bespoke metal pipe boxings to conceal external pipework.The more efficient heating system was installed as part of Islington Council’s ongoing cyclical repair programme, which assesses all properties on a 7 to 10 year cycle to establish where improvements need to be planned & implemented.The Pendock casings are manufactured from 2mm thick corrosion resistant aluminium and incorporate a brown PPC finish to integrate with the brickwork and provide a consistent finish to the project. The use of aluminium not only improves weather resistance, but also adds tough protection to the external pipework.

Our team manufactured and installed 26 two-compartment Laminate Heated Lockers to accommodate 52 people, designed for a wet area, which assures that there will be no risk of peeling or rust.The specification of two-compartment Heated Lockers were 1800mm high, 300mm wide, with 1mm rivets, and 450mm deep. Lockers are positioned on top of a 175mm stand, which allows the heat to enter the lockers through perforation. The Laminate Heated lockers were requested to be in ‘Gris Orage’ by Polyrey, which offers a visually pleasing design that matches the room’s colour scheme.Helmsman Heated lockers are the perfect solution for wet clothes, with laminate doors to fit your aesthetic needs. The lockers are manufactured with a perforated base as well as the shelf allowing the warm air to circulate inside the locker and perforated slots at the top allow the damp air to flow out.Laminate Heated Lockers were finished with Lowe & Fletcher Nimbus in Black. Nimbus is a great lock option since it gives users the peace of mind that their personal possessions are secured and it can be used in both public and private user modes, meaning it may be permanently locked up with a single code or used for day-to-day use.Helmsman Heated Lockers are a fantastic option for many industries. Heated lockers provide commuters and employees who require their damp clothes to dry before the end of the working day.If you have a project where heated lockers are required, or if you want to know more about helmsman products, contact us today at 01284 530496 or get your quote here today.

As a part of the development of the company, BT are planning to reduce their number of working locations from over 300 to just 30. BT Bristol features flexible workspaces, the latest IT and smart building technology, restaurants and cafes and a rooftop wildflower meadow terrace with panoramic views of Bristol.An important aspect of the development of this new building was its eco credentials. With the whole company seeking to reduce its carbon emissions, choices were made throughout the design and build process to support this aim. As well as the rooftop meadow, the building features a heating system from the low-carbon district heating network and aspects that encourage employees to make greener choices about their travel to and from work. In order to support this, the BT Bristol office building features parking for around 270 bicycles, as well as changing rooms, showers and lockers.Helmsman were excited to be contacted by Honeyfield Property Services to supply and install the lockers at BT Bristol. The client requested Heated Z Lockers, with hasp locks for the user to attach their own padlock.Heated Lockers are a great addition to a cycle storage area, providing a storage solution that can dry damp clothes as well as keep your items safe during the working day.The Z shape is a particularly good choice for heated lockers, as the user can hang their clothing in the taller area of the locker and let the heated locker do the hard work.Air flows through the locker through a perforated base, and perforations at the top of the locker allow the damp air to escape. The tube heaters are positioned within the stands of the locker and can be either plugged into a 3-pin power socket or wired into a fused switch.In keeping with BT Bristol’s aim for carbon efficiency, the laminate used for the project was Graphite by BioCarbon Laminates. This is one of Helmsman’s standard laminate options, and is a carbon neutral material.In addition to the lockers, we also supplied and installed seat stands, with adjustable feet, and ash hardwood seat slats. The stands, back and sides of the lockers were all cladded with matching Graphite laminate, and the lockers were finished with black circle discs with white numbering.It was great to work with Honeyfield Property Services on this project, and wish the BT Bristol office much success in the future.If you have a similar project, or want to find out more about our Heated Lockers, give us a call on 01284 530427 or fill in our contact form here.

ChallengeFor the air traffic controllers at Birmingham Airport, concentration is critical to ensuring the safety of the hundreds of passenger jets that take off and land every day. Studies show office workers lose concentration when noise levels hit 55dB; however, the sound of just one medium-sized aircraft descending at 1,000ft is 70dB.SolutionWith this in mind, noise reduction was an essential factor in the specification of the insulation for the 105ft air traffic control tower. The airport’s developers consulted Knauf Insulation’s Technical Support Team for advice. The Technical Support Team recommended Rocksilk® RainScreen Slab, a non-combustible Rock Mineral Wool insulation designed for use in high-rise rainscreen façade systems.Mineral Wool insulation has superior acoustic performance because of its open structure, which traps sound between the individual strands and turns it into heat energy.Rocksilk® RainScreen Slab is quick and easy to install and adapts to minor imperfections in the substrate. Slabs are flexible and knit together eliminating air gaps for maximum acoustic and thermal performance, making it perfect for use on the curved walls of the funnel shaped control tower. The same level of acoustic performance could not have been achieved with rigid foam boards, which have closed cell structures that offer virtually no sound absorption. Rigid foam boards are also more prone to air gaps, reducing acoustic performance further.As well as excellent acoustic and thermal performance, Rocksilk® RainScreen Slab is non-combustible with Euroclass A1 reaction to fire classification. This means it will not contribute to the spread or development of fire should it occur.Another factor in the specification of Rocksilk® RainScreen Slab was sustainability. It is manufactured with ECOSE® Technology, Knauf Insulation’s unique bio-based binder, which contains no added formaldehyde or phenol. It is made from natural raw materials that are rapidly renewable, and is 70% less energy-intensive to manufacture than traditional binder, so it is more environmentally friendly. Products made with ECOSE® Technology generate low levels of dust and VOCs, and have been awarded the Eurofins Gold Certificate for Indoor Air Comfort.Thanks to Rocksilk® RainScreen Slab the air traffic controllers at Birmingham Airport can enjoy a quieter, warmer, safer and more sustainable workplace."Acoustic protection, energy performance, fire safety and sustainability were all crucial factors taken into account during the design of the air traffic control tower and so all materials specified with the project needed to meet these multiple requirements. We are extremely pleased with the building."Will Heynes, Birmingham Airport’s Development Director

An energy efficient approach to construction, using low maintenance building materials together with Dimplex ground source heat pumps, is proving the key to cost-effective heating at a collection of ten new homes built by Shetland Islands Council in Brae.

Project BackgroundHoe Bridge School is an independent co-educational pre-prep and prep school in Woking, Surrey. The sports hall had been heated by an old radiant system supplied some 35 years ago. The old system was past economical repair so the school decided to invest in a brand new radiant heating system. Contractor, ABS Ltd had over the years maintained the facility, so the school looked to them for advice on replacement equipment. Powrmatic were approached by ABS Ltd and undertook a thorough survey of the sports hall, with a view of replacing the old system with a new Powrmatic SRP – PCV continuous radiant tube system.Project SolutionAlthough the concept of the new heating system is very similar to the old one, there are sound reasons for the like-for-like type replacement. Radiant heating in sports halls is well established as it provides an environment of uniform heat coverage without stuffiness where sports activities can be performed in complete comfort.The new Powrmatic SRP – PCV continuous radiant tube system comprised two radiant branches, each 22m long, down the length of the hall, each branch containing 2 x PCV 23kW burners, all feeding to a vacuum fan to extract the products of combustion. This arrangement virtually mimicked the original layout to reduce the installation time and costs.Project ResultGas fired continuous radiant tube heating is a proven type product being the most appropriate solution for the challenge presented by sports halls, maintaining comfort levels whilst minimising fuel usage and carbon emissions.The SRP-PCV system combusts fuel at the point of use and has the capability of modulating down to 60% of high fire whilst maintaining efficiency but reducing fuel consumption. The Powrmatic SRP-PCV system is designed and manufactured in accordance with BS EN 17175:2019 for Multi-Burner Systems and incorporates a patented burner metering device.The Powrmatic SRP-PCV & PCV+ systems have been validated following review against government approved high performing energy efficiency criteria, with a Seasonal Space Heating Energy Efficiency (SSHEE) of greater than 90%, thus allowing inclusion onto the ETL (Carbon Trust, Energy Technology List). This high efficiency reduces energy usage, operational costs and carbon emissions.

No timber was allowed as part of the new refurb to conform to FM Global (Airbus Insurers) regarding system fire rating. IKO recommended an overlay on the existing deck, which complied with all the latest British Standards and Regulations. IKO Mach One System was chosen as it provided a flame-free System. Where detailing was difficult IKO Polimar EC/UV System was used. The roof refurbishment also included the installation of smoke vents, associated smoke control panels and accessories.

OverviewPowrmatic supplied a TEG41 air rotation heater for a large distribution warehouse facility in Bristol which was installed by our trusted partners at RSY Air Conditioning.Project BackgroundSupplying the motor trade for over 50 years, Apec Braking is firmly established as the leading specialist braking supplier to motor factors throughout the UK and Ireland. The 10,488 m² distribution warehouse required frost protection with design parameters of -5°c external and +10°c internal.SolutionJust one TEG41 air rotation heater was installed by our trusted partners RSY Air Conditioning. This TEG41 heater was designed to deliver an impressive 420kW of heat output. The TEG41 heater uses high volume, low velocity, air-circulation to distribute conditioned air to large open space and is the perfect solution for any distribution warehouse heating requirements. Due to the customers requirement to maximise the amount of racking within the warehouse area the distance of the unit from racking was much less than would be usually recommend (it was under 2mtrs from face of heater to face of full height racking).ResultThe newly styled Powrmatic Air rotation units in our new RAL 7015 colour were installed by RSY Air Conditioning. The unit was redesigned at the top of the unit to be top exit rather than the conventional design. The theory behind this was to direct the leaving air towards the roof and use the internal profile of the roof to aid with stratifying the air across the building length. The racked distribution warehouse will now benefit from a frost protection system which will protect the internal sprinkler system from freezing in the colder months.

Located within the Kirtley building, close to the cycle storage compound, are changing facilities with a number of showers, hairdryers and mirrors. As part of the upgrade to these facilities, the University has installed Heated Z Lockers. The shape of these lockers was chosen so that the user has the full height of the locker to gently dry their clothes and equipment that they used to cycle to university.This unique shape makes them the perfect design for heated lockers. Simply hang your damp clothes inside and let the Heated Z Locker do the hard work. Air flows easily inside the locker, with a perforated base, and perforated slots at the top allow the damp air to escape. Single and twin tube heaters are available, with the heat source plugging into a 3-pin power socket, or wired into a fused switch.A range of materials and colour finishes are available, and the University of Derby chose Laminate Z Locker doors in two colours. Laminate is a great choice of material as it creates a more Heavy Duty locker less likely to scratch, dent or damage.With a large range of laminate manufacturers, including a carbon-neutral laminate supplier, our Heated Z Lockers can be a bright pop of colour through to a neutral wood affect laminate. The University of Derby chose two contrasting laminate colours in colours Sage and Elegant Grey from BioCarbon Laminates, providing a modern look to the Z Lockers. The lockers were also manufactured with seat stands, with the slats matching Elegant Grey door colour from BioCarbon Laminates.We can also provide a range of accessories, from multiple lock options through to wrist straps, particularly popular with leisure centres and gyms. The project at University of Derby included oval laminated numbering, Lowe & Fletcher coin return locks and grey wrist straps.The university were very pleased with their Heated Z Lockers, and we have since been back to measure up for some more laminate lockers.

A detached new build house in Pontyberem, Carmarthenshire, has incorporated a Grant Aerona³ air source heat pump and Monowave cylinder to deliver its heating effectively and sustainably.

A new flooring solution was required as part of a large, high-specification selfbuild housing project on the stunning Archerfield estate in North Berwick. Underfloor heating had been specified for the ground floor of the house and it was important that the chosen floor solution would help to optimise heating efficiency. Given the scale of the project it was also important that the chosen screed solution could be installed quickly over a large area to fit within the build programme. Following initial discussions and a successful pump trial the customer decided to use Tarmac’s TOPFLOW Screed C cement based liquid screed.TOPFLOW Screed C is a free-flowing, cement based liquid screed that can be trafficked after just 24-48 hours and dries within 21-28 days. It can be pumped into place and allows large areas to be covered quickly with up to 120m2 laid in as little as 45 minutes. Fast drying times mean it can be laid later in the programme when the building is fully water-tight and still hit deadlines for installation of flooring. It is ideal for use with underfloor heating systems. As a self-compacting screed, it fully encapsulates heating pipes without leaving any voids and is also a more conductive medium than traditional sand and cement screeds, improving the thermal performance of the system. It is also compatible with most cement based adhesives meaning it can be used with a wide range of flooring types.The fast-drying times and early trafficking characteristics of TOPFLOW Screed C enabled other trades to follow on quickly, helping to provide continuity and efficiency within the client’s build programme. The contractor was delighted with the outcome, commenting on how good the material was to work with and on the excellent finish achieved.

The Audley Stanbridge Earls retirement village is an exclusive residential development of 155 luxury retirement apartments and cottages designed around a Grade II listed Tudor Manor house on a 32 acre site near Romsey, in Hampshire. Underfloor Heating had been specified as part of the design and the large floor areas now needed to be finished with floor screed that could be installed quickly and efficiently within the operating windows provided by the main contractor.TOPFLOW Screed A Thermio + offers a higher thermal conductivity than conventional sand-cement screeds, can be laid thinner and fully encapsulates heating pipes without leaving any voids. This makes it ideal for use with underfloor heating systems where it helps to improve the thermal performance and energy efficiency of buildings. All TOPFLOW Screed A products are made from gypsum and are completely cement free, with a binder made from 98% recycled material. This gives it a lower carbon footprint than a conventional cement-based screeds, saving up to 20.45kg CO2e per m2, making it a more sustainable choice.
