"industrial fire doors"

Jewers Doors have completed the installation of five of their Osprey sliding folding doors to new private aircraft hangars and integral fire station at Old Warden Aerodrome in Bedfordshire.

Premier Security & Fire was commissioned to design, fabricate and install six sets of security doors at University College Hospital London (UCLH).Instructing clients Kyotec Group required a LPS1175 SR2 security standard on all doors, including one set of double doors with a 60-minute fire rating.Premier's portfolio of certificated doors, screens and gates ranges from LPS1175 SR2 to C5 (SR3); D10 (SR4) including fire-resistance to EI 60 and E90, and thermally-broken options.For more details of Premier Security & Fire’s extensive range of security doors, windows, screens, and gates, including Secured by Design standard, call our Managing Director Neil Johns, on 0208 559 8295. He will be happy to take your call.

Compartmentation, Protected Means of Escape and Boundary Protection were all required as part of the fire safety solutions and therefore Coopers FireMaster fire curtains and Coopers FireMaster Plus2 fire curtains were installed to ensure the fire safety requirements were met. In total, 113 fire curtains were installed, 96 with round headboxes and 17 with square headboxes. Round headboxes were engineered for The British Museum as a request from the architects. The headboxes of the fire curtains were going to be seen by the occupants so Coopers engineered a round headbox that looked in keeping with the design of the building.

DRU gas fires and a Spartherm wood fire were specified by Ethos Construction and DRU dealer Grate Expectations for Harford Manor, a country house in Holyport, Windsor. They selected the fires for their ‘A’ energy ratings. This included the DRU PowerVent extended flue system for flexibility of location. In addition, the gas fires can be operated using the DRU Eco Wave app for tablets and smartphones. Ethos project manager Niten Mistry said: ‘The fires were selected for their impressive performance and ease of installation. They also contribute to the high quality of the property.’ www.harfordmanor.com, www.grateexpectations.com,

The Cooperage is located on a former industrial site in Central London and is believed to have been built in the early 1900s. Following an unsympathetic earlier restoration in the 1990s, Chris Dyson Architects were invited in 2011 to prepare a scheme for the extension and complete renovation of the property, turning it into a spectacular five bedroom family house. The Cooperage has been nominated for the RIBA House of the Year 2017 long list. Photography by Peter Landers.

An innovative door design was required for a new manufacturing process about to be introduced in the new Nissan battery plant manufacturing facility. Project/doors:100 Bespoke Conveyor screensThe challengeNissan required a unique door for a new production facility. The doors needed to give 60-minute fire resistance and be capable of completing up to 400,000 open/close cycles a year. Further, the doors needed to meet strict air leakage criteria and be able to withstand sudden air-pressure increases. The doors also had to interface with third-party equipment such as conveyor belt controls and fire alarms. Each required an LCD display control panel that provided a quick and easy diagnosis of what each door was doing at any point in time. The solution Using an already proven design solution which Hart developed for the baggage handling system in Heathrow’s Terminal 5, Hart adapted the product to suit this new requirement. As this was not a product already on offer, invention and rigorous testing were required.The successA decade has passed since the doors were installed and commissioned. The facility continues the manufacture of the battery cells and the doors remain a critical part of the success of the plant and have proved exceptional reliability and total cost of ownership

The existing ornate and decorative features of the hotel, meant that the fire curtains needed to integrate with the existing parts of the building that were remaining. This included a four sided, marble clad atrium in one of the main entrance halls, which covers two floors. There were four fire curtains installed around the first floor of the atrium therefore reinstating fire separation between floors. Fire curtains offering up to 3 hours fire resistance were also installed in the new hotel kitchens, preventing fire from spreading from kitchen areas to the public dining rooms and bar.

With stringent demands in terms of design, comfort, and functionality, the new City of Glasgow College is considered a ‘University of the Future’. GEZE UK made a key contribution to the modern look & feel of the technical college with custom door solutions, including revolving doors and swing doors.State-of-the-art door systems for the City of Glasgow CollegeThe £228 million project for a capacity of 40,000 students and 1,300 employees was completed by the Sir Robert McAlpine construction company. The entrance areas on the west and south sides were designed using GEZE door technology to reflect the structural aesthetic of the City Campus.The highly modern new building, with over 1,000 classrooms, boasts a striking design while fulfilling high requirements for functionality and safety.Manual revolving doors ensure the flow of trafficThe west and south wings impress with modern steel and glass façades with two manual revolving doors. An additional automatic swing door was installed directly beside each of the revolving doors.Manual revolving doors with TSA 325 NT door drives are the ideal solution for the building's specific requirements in terms of functionality and ease of access. The generous door leaves are easy to move, and the integrated control mechanism stops pushing behind an individual entering into the swing door. In addition, the revolving doors effectively protect the lobby from draughts, dust and noise.Automatic swing doors, designed as emergency exitsThe automatic swing doors directly besides the revolving doors were equipped with electro-mechanical GEZE Slimdrive EMD-F swing door drives to offer maximum flexibility. They can be activated with the push of a button, providing barrier-free access for persons with restricted mobility. The door drive is just 7 cm tall, and integrates discreetly into the door frame to move the door leaf precisely, reliably, and extremely quietly. In the event of a fire, the swing doors also serve as barrier-free emergency exit doors.Automatic sliding doors: effortless door comfortA single leaf automatic sliding door with GEZE Slimdrive SL NT drive guides students and visitors into the interior of the Riverside campus. The highly modern building, which was nominated for the prestigious Stirling Prize, houses student accommodation hat is home to over 3,000 ship building and marine technology students.The slim Slimdrive SL NT drives (just 7 cm tall) integrate almost invisibly into the modern, column-encased entrance area, moving door leaves of up to 125 kg quietly and effortlessly. This makes it the ideal drive solution for a public building with consistently high traffic in both directions – especially one such as Riverside that is also used as a residential building. GEZE's modern door solutions have played a key part in ensuring students can move comfortably and safely through their environment.

ForFarmers is a market leading international feed company that offers feed solutions for conventional and organic livestock farming.Project/doors:21 Hart Doors across 4 sites including Speedor Super, Speedor Storm and Speedor MiniThe challengeDue to the contents of the building, regular industrial doors were not acceptable as they had to be left open, allowing pigeons to enter the building, resulting in damage to the produce.The solutionThe front elevation of the building had to be sealed to prevent vermin egress while also allowing truck access in a fast and safe way. Speedor high speed doors activated by vehicles allow for efficient movement in and out of the building.The successThe doors, installed at feed intake tipping bays, improve aesthetics of the facility, prevent ingress of wildlife into the building and dust being blown over adjacent properties. Speedors do a tremendous job when required for fast open/close cycles at locations such as this where tipping feed can create dust for example. We designed taller and narrower doors – 7.5m high x 3.2m wide – to accommodate the dimensions of the tipping trucks and overall the installation works very well for a happy client

The Coopers FireMaster®, closed rectangular Concertina fire curtain is a perfect solution when requiring fire compartmentation around a staircase as it offers a virtual firewall creating a lobby once the curtain has been deployed with more than 2 hours integrity. The innovative Concertina fire curtain installed at Aldgate Tower fully encapsulates the staircase from the 11th to the 12th floor in the event of a fire. The curtain is triggered by either the fire alarm system or a local heat or smoke sensor and is automatically deployed from the ceiling to the floor.

Deptford Fire Station is a Grade II listed building in Lewisham having been originally constructed in 1903. Bolton Gate supplied the folding appliance bay doors in the 1960’s and although still functional after fifty years, they were in need of replacement due to frequent usage. Since the building is listed, every effort was required to replace the doors on a like for like basis and Bolton Gate were engaged to supply new folding shutters to the same design which were installed and handed over recently. This is the latest in a list of several fire station contracts undertaken in London.

Coopers installed and commissioned two FireMaster® Plus fire curtains, the first to protect the property from fire and smoke migrating from the kitchen whilst the second to protect the internal balcony from smoke and fire travelling between floors. Both fire curtains provide 2 hours fire and insulation zone protection and were installed into the ceiling to remain hidden from view until deployed by a fire alarm.

How to incorporate a fire or stove installation into a self-build project.By Niall Deiraniya, UK general manager, DRU FiresAlways ask for the fireplace specification at the design stage. Modern gas fires and wood stoves require careful planning in order to work as part of the general home heating system.Gas, wood or other fuels?Decide which fuel type best suits your home. Modern gas fires have realistic flame pictures and are much more energy efficient than older models.Wood stoves and fires also have greatly improved energy efficiency due to Ecodesign regulations. The only downside is that there is much more work involved with buying and storing the wood and cleaning the stove after use.Both gas and wood have room sealed options. This means that no air from inside the home is used for combustion and all waste emissions are expelled outside, resulting in clean burning and high efficiency.Finally, sustainable fuels such as Bioethanol produce a very attractive flame picture, burn cleanly with no smell or emissions and are available in a large selection of design formats. Built-in or freestandingIf you are converting a house with an existing chimney, you may wish to retain the chimney, to incorporate a more modern fire. Conventional flue gas fires are designed to fit seamlessly into standard chimneys and require minimal building work. The chimney will almost certainly need sweeping before installation and the fire may require a chimney liner for essential safety.Most wood fires are also designed for chimney installation and make full use of the air circulation properties to provide visually attractive and energy efficient fires. You can either elect for a basic ‘insert’ fire, which matches the dimensions of a Class 1 chimney or a widescreen model, which will require some structural changes.Freestanding stoves are very popular, as they offer greater flexibility of location and provide dramatic room features. They are available in gas, wood or bioethanol and generally need a flue connection to an outside wall or through the roof. No chimney optionsContemporary balanced flue gas fires are designed to be installed without a chimney, so you can incorporate them almost anywhere in a self-build project. However, they still need to be specified at the earliest possible stage. A typical installation will require the fire to be flued through an outside wall, with the flue concealed behind a false chimneybreast. Fires can be located in room-dividing walls and other architectural features so they can be seen from both sides. You can also enjoy fires in kitchens, bedrooms, loft conversions and many other places. These types of installations are made possible by extended, fan-assisted balanced flue systems. They allow for multiple fires to be placed in larger properties, with the flues hidden in crawl spaces and other discreet areas, terminating on the roof.In conclusion, the secret to having attractive and energy efficient fires and stoves in any self-build project is design, plan, cost and implement. And always consult a fully qualified Gas Safe or HETAS engineer.For further information visit www.drufire.com

Staff at DBK Technitherm can now face the winter knowing they won’t have to battle the elements, thanks to Union Industries, the UK’s leading manufacturer of high-speed industrial doors.

Jewers Doors has for many years supplied contour doors which are specially shaped to encompass the fuselage of an aircraft in order to provide an environmental seal. These doors allow part of an aircraft (e.g. the nose or tail) to be within the controlled environment of a hangar for maintenance, repair and overhaul (MRO) operations. With part (often the major part) of an aircraft remaining outside the hangar, space within the hangar is available for other aircraft to be worked upon – thus increasing productivity. Such an arrangement also means that MRO operations can be undertaken on larger Code E and F aircraft in hangars that would otherwise be too small.

Specialist commercial refurbishment company Saracen Interiors delivers four floors of stunning Grade A office accommodation in the heart of Watford’s Met Quarter. Early discussion with Forza regarding project floor plans and elevations enabled the Forza team to prepare veneer layons that fully utilised the potential of the species distinctive decorative features and then create panel layout drawings in order that product delivered to site was clearly sequentially numbered for installation. Incorporated in the project joinery component package for Forza were items such as skirting and lift surrounds in addition to mirror frames and IPS panels for “Boutique” style washrooms.

“A great achievement by all involved”– Neil Turvey, UCL Estates Assistant Director Capital ProjectsOverviewUCL is one of the world’s leading universities, as well as being London’s number one university for Research Strength, where they have consistently led the way with not only their academic excellence but also their global impact.UCL PEARL (Person-Environment-Activity Research Lab) was completed in Autumn of 2021 and is a unique facility, designed to explore how people interact with their environment in a groundbreaking 4,000m² building. Sophisticated systems are used to gather a rich array of information which will help to understand these reactions and how they can be used to create a better urban environment for the future.PartnershipHAG Ltd. were tasked with protecting the building both through the supply & installation of essential fire protection systems, such as fire shutters & fire curtains and high security steel door sets throughout the building, located in Dagenham, in the London Borough of Barking & Dagenham.As a UK wide company with nearly 40 years’ experience in dealing with large scale contracts of this size, we were able to assist the main contractor by ensuring reliability, professionalism, safety and ensuring that the project was completed on time.All our fire protection products are fully compliant with the Regulatory Reform (Fire Safety) Order 2005 and certified to UKCA.All of HAG’s fire curtains have been independently tested and certified by the international fire testing experts at Warrington Fire, are tested to the latest standard BS EN 1634:2014 and marked to BS EN 13241-1:2003.HAG Ltd.’s steel doors offer an exceptional level of security, whilst not compromising on aesthetics. Our doors were made to the specification of UCL PEARL, to seamlessly sit in their surroundings and ensured not only security, but they are suitable for high levels of use and offer thermal insulation. The ProjectThe original UCL PEARL site consisted of various buildings, one of which was Grade II listed 1940’s. The new building is the first zero-carbon in-use building for UCL, and one it hopes will set the bar for future developments.Within the 10m high building, you will find life sized environments, such as a train station, village square, high street, even a pop-up theatre, all of which have fully controlled conditions and the ability to change materials, such as the flooring or wall cladding. UCL can adjust lighting, sounds and experiment with smells and the other senses to see the impact that these changes have on people. “A building that will be able to house the world”– Nick Tyler, Chadwick Professor of Engineering and Director of UCL Centre for Transport StudiesUp until now, assumptions have been made about how people react to environments, but this has been based on outdated data. UCL PEARL can now pave the way, with the use of sophisticated systems, such as eye trackers, brain scanners & accelerometers, to ensure a more informed suite of ground-breaking data going forward.UCL PEARL are already working in partnership with the London Underground and are researching the design of the built environment for people with dementia.Not only are there legal requirements and obligations for fire safety and protection within this building, but fire shutters & fire curtains should be regularly maintained to ensure they are suitable for intended use, they are safe to use, in good repair and subject to a program of monitoring & reviewing.This is another reason that HAG Ltd. were chosen to assist with this unique facility, as we can offer a full & comprehensive maintenance & repair service, to ensure that their fire shutters & curtains continue to work efficiently and with ease.

It’s prime time for the education sector to refurbish and service institutions. Helmsman manufactured and installed almost 200 new laminate lockers in a high school in Manchester. These laminate lockers were extra heavy duty. Having ‘extra’ heavy-duty lockers means that the laminate doors inset into the locker frame and creates extra durability. The advanced locking design provides a return lip within the internal door frame for the hooked cam to lock behind. In addition, there is a locking slot in the door frame upright that enables secure locking in two places. These stable and fire retardant four compartment lockers have created storage for 776 students.The Laminate used was Arpa Fucisa, which makes the corridors pop. The laminate lockers are all standard sizes of 1775mm high x 300mm wide x 450mm deep. This project included a standard 150 mm stand with the rear leg which has been cladded with matching laminate panels to have a fully secure, clean and aesthetically pleasing effect. Arpa Fucisa also used for the sidewall to locker infill. Chorlton school chose to have engraved numbers on each locker door. Using this solution for numbering protects the lockers from vandalism.Helmsman is the leading manufacturer of a complete range of lockers and cubicles in the UK and a specialist in providing solutions across different sectors from leisure, healthcare and education through to commercial, retail, construction and industrial. With a dedicated and experienced in-house design team supported by its on-site factory, the company produces high-quality lockers manufactured for each project.

Bioethanol fires require no chimney or flue, give off no harmful emissions and are 95% energy efficient. They are available in a large selection of designs for living rooms, kitchens, bedrooms, bathrooms and gardens. A good example is the home of Bury resident Anthony Norman, who chose an Italian kitchen and a British made bedroom from local dealer Icon, both featuring table-top bioethanol fires. Anthony and his family were convinced that they would make exciting additions to their new kitchen and master bedroom. Ebios bioethanol fires are made in Germany and distributed by DRU in the UK.

As the leading manufacturer of fire and smoke curtains, Coopers were appointed to develop a smoke curtain system to provide an unintrusive method capable of controlling smoke migrating from the lower floors. It was also necessary to protect the un-insulated glazing installed above the atrium’s reception area with an approved fire curtain barrier system approved to provide a one hour insulating zone. Coopers manufactured, installed and commissioned two SmokeStop smoke curtains developed to control smoke generated in the event of fire and effectively channel it away from occupants during evacuation.

London Stadium (formerly and also known as Olympic Stadium) is a multi-purpose outdoor stadium at Queen Elizabeth Olympic Park London.Project/doors:21 Fire and Security shutters (2010)50+ Fire and Security shutters (2015)The challengeHart assisted with the specification prior to the award. Technical collaboration was ongoing ensuring that integration and operation of the shutters went smoothly with safety and continuity in mind.

From early design discussions to your final commissioning activities of the 50 new shutters onsite, it was a pleasure to work with such proactive and knowledgeable organisation.” Jon Pepper, Project Manager, Balfour Beatty

Crystal Window & Door Systems fabricated over 2,100 windows and doors for the project. All of the windows and the storefront of the structure were coated in Powdura® 5000 coatings from Sherwin-Williams General Industrial Coatings,in the colors Bronze and Cloud. The fluoropolymer resins and solar reflective pigments in this powder coating defend against UV radiation, enhance thermal stability and deliver a hard, durable finish to combat wear and tear. As a result, the materials will require less maintenance, because the durability of these coatings will serve to protect the integrity of the structure’s design well into the future.

From a design concept to delivering a compliant secure solution, Eurobond worked with a leading Worldwide tech giant to provide steel door sets to meet their function and performance.

The Coopers FireMaster, closed and open Concertina fire curtain is a perfect solution when requiring fire compartmentation around a staircase as it offers a virtual firewall creating a lobby, once the curtain has been deployed, with more than 3 hours integrity. A total of five FireMaster Concertinas were installed between floors 11 and 15 in this large office space. These curtains allow for the open plan flow of the building to remain as intended and prevent the spread of fire through the building whilst providing compartmentation.

Hart has supplied hundreds of industrial doors to infrastructure projects both across the UK and internationally.Project/doors:9 Electric insulated roller shutters14 Speedor Super high speed doorsThe challengeOld rail shutters are unreliable with a potential to free fall due to mechanical failure. Doors that are past their ‘asset life expectancy’ should be replaced to ensure up to date legislations are met. These areas tend to have varying traffic and need to be secure for safety. These dangerous situations can be remedied by replacing with new doors designed for purpose. The solutionHart completed a major contract to replace old and unreliable shutters at the Stewarts Lane depot, Battersea. The contract included the removal of old doors and re-installation of nine doors of varying sizes, the largest being 8.5m wide and 4.7m. Safedrive motors delivered quiet and smooth operation despite the size and improved security and safety for staff.The successHart replaced 14 of it’s own Speedors installed at Laira Depot, Plymouth which were still operational after 22 years. This is an astonishing length of service and a testament to the quality of product. Hart’s reputation for technical excellence developed over many years has given Hart a distinct edge when involved such contracts.The Review:“Your installation staff were extremely efficient and friendly workers. They carried out the work safely in a professional manner and there were no issues or problems on site. Both of them were a credit to your company.” First Great Western Ltd

Product constituents: To meet UK fire standards the Access Panels manufactured have been tested by Warrington Fire and hold a 120-minute fire rating certificate.

Coopers Fire installed a large, multi-faceted FireMaster Concertina Closed fire curtain on floor 12. The client utilising floors 12 and 13 wanted to keep an open plan feel between floors to allow a more free flowing environment for the staff. To achieve this, a bespoke staircase was designed connecting the floors. The spiral staircase was a major feature on floor 12 and meant that staff were able to move freely between floors 12 and 13 without using the lifts.

The hospital needed to ensure good accessibility and create demarcation areas for staff and visitors. We provided various systems including automatic revolving doors and sliding doors, an automatic revolving door with a diameter of 5.4 meters, and various swing door operators for the automation of both wooden single-action doors and fire-resistant doors. We installed swing door operators and sliding door operators which ensure convenient, comfortable and safe access between the departments. In addition to the benefits of comfort and energy-savings, the solution provides safe escape routes and easy access for both able-bodied and disabled people.

Barry Fire Station / Altro case study

When undertaking a heating, ventilation and air conditioning (HVAC) maintenance and upgrade contract on a North Sea offshore platform, RBG Limited identified that critical noise levels were apparent in a range of working areas.Investigating the issue, RBG Ltd commissioned environmental sound testing, which revealed that ambient noise exceeded a specified minimum of 55dB (A) throughout the electrical workshop, store room, hydraulic workshop, subsea office and mechanical workshop, reaching its highest levels of 88-96dB (A) in the mud pit room. Additional noise generated by operating pumps, cranes and machinery would further increase the noise levels in these areas.As such, RBG Ltd needed to source a high performance industrial acoustic solution that would sufficiently reduce the noise contamination and make the working environment acceptable.Seeking expert industrial acoustics advice, RBG Ltd briefed CMS Acoustics on the project parameters, who responded with a bespoke ISO Acoustic Enclosure Panel system design.The SolutionThe ISO Enclosure Panel is a prefabricated sound reduction system, designed to create noise-protected structures in industrial environments. A self-supporting and robust construction, it offers the additional benefit of a short assembly time, facilitated by the panels being lightweight and easy to handle.The industrial acoustics technical team at CMS Acoustics calculated that a combination of 50mm and 100mm thick ISO Enclosure Panels would be required to achieve the specified noise reduction in the different areas. Depending on panel thickness, fire resistance ranging from 30 minutes to two hours can be achieved.For RBG Ltd, CMS Acoustics manufactured the panels in white and supplied them in ready to assemble kits clearly labelled according to area for installation. Some panels were manufactured to allow removal for maintenance while others were designed to be stud welded to external walls.To increase system robustness, CMS Acoustics integrated acoustic doors and vision panels into the ISO Enclosure design.

Since the Grenfell tragedy in 2016, there has been an increased focus on fire-safety compliance in all communal buildings. This focus sharpened even more when, early in 2018, the media unearthed evidence of some non-compliant products having been installed there, including internal fire doors that had been fitted without smoke seals. As a result, there has been heightened attention on every aspect of safety, not least on fire doors. Fire officers and building management personnel understandably want to ensure they have covered every possible safety angle.To this end, they are now often insisting on going beyond the specifications required by regulations.However, in trying to ensure doors provide the maximum protection against fire and smoke, another potential problem can arise that, if not addressed, can undermine those good intentions.The problem:One of our customers, a door manufacturer and installer, had recently supplied doors but then been informed by their customer that they were not successfully self-closing as they were meant to. The assumption was that the door closer was not performing correctly, so the ‘fault’ was relayed to Rutland with a request for a resolution. We agreed to visit the site swiftly to assess the situation. Our inspection found that the door closer was correctly specified for the width and weight of the door, but that the smallest possible door gaps had been specified. These, coupled with substantial smoke seals around the doors, were causing significant resistance to the doors closing. Although the resistance was due in part to the physical aspects of the small gaps and the seals, the main problem was actually the build-up of differential air pressures on either side of the doors.Given the increased focus on maximum fire defence at doorways on all new-builds and building refurbishments, this problem is arising ever more frequently. Tighter door seals have the effect of creating separate, near air-tight pockets within a building, each holding air at slightly different pressures. The bigger the building, the more such pockets and the greater the pressure differentials that can potentially build up.These pressure differentials can have a significant additional effect on the amount of force needed to close each door and must be taken into account when choosing and setting closers.The Rutland response:Rutland’s technical team attended the site as required to support the customer in achieving a solution, first to identify the issues with air pressures and then recommend and implement a solution to the problem.Initially, we made hinge and latch adjustments to the door sets to overcome some of the resistance. This proved to be insufficient to ensure all the doors correctly closed first time, so we advised upgrading to stronger door closers. This recommendation was supported by supplying the door manufacturer with relevant data from previous tests on an equivalent door set to verify the product’s suitability.The new closers were delivered to the site and our technical team remained on hand to provide extensive assistance with the installation. Rutland created a bespoke jig to aid the door manufacturer’s installers in fitting the replacement door closers, significantly cutting down the time it took to rectify the problem.Outcome and key learning points:The project was successfully brought back on track, to the full satisfaction of the property owner and the door set manufacturer. All doors now function as they should and are delivering the intended fire safety for all building occupants.This case highlights that, due to heightened protective sealing around doors, there is an increasing likelihood of air locks forming in buildings, which means that specifying of door closers cannot be based simply on weight and width of doors, as has traditionally been the case. The pressure differentials that result vary building by building, based on each one’s layout, so it necessitates careful assessment to ensure that appropriate closers are specified.
