"cavity closer"

RC was approached by Dorsey Construction Materials to supply our award-winning cavity fire barriers and cavity closers for a high-rise housing development in Dagenham.

Dacatie's TFR Fire Rated Cavity Closers were used in this residential project by Willmott Dixon. The 133 homes come in a mix of 2, 3 and 4 bedroom houses, and 1 and 2 bedroom apartments. It is part of the Bristol Mayor’s commitment to build 2,000 new homes, including 800 affordable, in the city.

Anthracite Grey Eurocell Eurologik 0.8 U-value triple-glazed windows with fully post-consumer recycled PVC-U cavity closers have been specified by Morris Homes on Vista, the UK’s largest zero carbon village in Peterborough.

A systematic approach of arresting and reducing the flow of water within a cavity wall prior to any change in status of that wall helps balance demands on damp protection measures. In the case of a circular window passing through a curved cavity wall, protecting against damp ingress is easily achieved using a preformed Type K cavitray. The preformed Cavitray is curved to match the wall. Conventional flat material or roll material cannot uniformly match the radius of a wall.

Delta Registered Installers, Bensleys provided a waterproofing solution on an iconic Brighton structure.Steeped in history and thought to be built on the original Brill Baths site, sits Clarendon Mansions. This large, detached structure is thought to have been built in 1870 by Charles Brill during the Brighton boom.The four-storey building facing Brighton’s famous sea front, was originally constructed as a hotel.Numerous refurbishments over subsequent periods of time, saw the structure move from a hotel to a public house, with the basement area being unoccupied for nearly a decade.The basement area boasts large, vaulted areas to the south and west elevation, with the south-side possibly being part of the original Bath structure.Bensleys were instructed by the main contractor, Pilbeam Construction on behalf of Evolution Architects, to help design, specify and install the waterproofing system.There’s no one-size-fits-all when it comes to waterproofing design. With the basement suffering from water penetration, Bensleys worked with the design team at an early stage of the project to ensure the right approach be taken, which included multiple factors such as: customer requirements, standards, robustness, cost, resources, time, skill required, safety and expectations of ground water which all translated into a design solution.

Commissioned by 30 member states of the European Union, the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) monitors the climate and weather. In light of climate change, the data it collects using complex satellite systems is becoming increasingly important. The growth of the organization associated with this is reflected in the continuous expansion of its HQ in Darmstadt. The construction of a new six-floor office building also includes a canteen for all employees working at the location. This canteen gets its unmistakable face from a lamella-style suspended ceiling made of golden PC-ALU 6010 aluminum mesh from GKD – GEBR. KUFFERATH AG.Modern weather forecasts today have little in common with traditional country weather lore. Satellites make it possible to monitor the climate and weather on a global scale. The data collected is then used to keep authorities, citizens and companies up-to-date with the latest developments at all times. In Europe, EUMETSAT monitors the atmosphere, oceans and earth’s surface around the clock and then transmits the data to the participating EU member states. Established in 1986, the organization opened its headquarters in Darmstadt in 1991. However, ever increasing requirements and staff numbers meant that the operation quickly outgrew its original space. A six-floor office building with 160 workplaces represents the final phase of a whole range of extensions and new buildings. Following a construction period of just 18 months, around 100 employees were able to move out of their temporary container offices and into the new building costing around €10 million, while a further 60 new employees are set to follow. The shape of the new building, designed by Pielok Marquardt Architects from Offenbach, is a mirror image of an existing building. Beside excellent energy efficiency and multifunctionality, the new building is characterized by transparency and modern design. Four office levels offer versatile space with transparent partition walls for any desired arrangement – whether open space, combination offices or classic cubicles.Functional division – exceptional aestheticsThe ground level comprises two separate functional units that can be accessed via separate entrances. Beside a control center for a new satellite program, this is also home to the campus kitchen with connected canteen for the workforce at the location, which has now grown to include around 600 employees. The kitchen has been designed to provide 410 meals a day and the canteen offers 250 seats. The mullion-transom facade also ensures that the room is flooded with light. Carefully chosen furnishings divide its area into various acoustically optimized zones. The white of the desks and chairs is picked up by strips in the glossy flooring and the cladding of the food counter, pillars and supports. In the central zone, bright red benches with high, sound-absorbing backrests offer a vibrant contrast. The color scheme is rounded off by the warm brown of the stone floor and the wooden acoustic cladding. However, the striking element in the room is the suspended ceiling, made from 400 square meters of golden aluminum mesh. Its 120 elements with a blade-type design mimic the appearance of sunshine in the canteen with their discreet shimmer. LED lighting strips further underline this impression. At the same time, the mesh conceals the ventilation technology with incoming air outlets on the element frames. As a result, the accessibility of the woven ceiling elements was among the key requirements for GKD. The planners opted for a particularly open mesh design in the form of the PC-ALU 6010 mesh with various warp and weft wire thicknesses. The function and aesthetics of the ceiling mesh thereby provide the desired high level of comfort in the canteen, while also making the room a unique feast for the eyes.

The forming of a level threshold would be easy if the designer did not have to consider the prevention of damp ingress. The problem is a number of elements converge at a threshold, and when the threshold is required to be practically level, it can be difficult to bring together protective measures in a manner that promote integrated functionality and structural convenience. A different approach to forming level thresholds is offered by Cavity Trays Ltd. It literally and physically covers the problem. The Type LTT Level Threshold Tray is a three-dimensional preformed DPC that envelops opening masonry skins.

Richard Richardson-Derry of GEZE UK looks at how a properly fitted fire door with the appropriate components can give occupants vital time to escape in the event of a fire.Despite what most people believe, toxic smoke is the cause of the most deaths in fires, as opposed to the fire itself. So what constitutes a fire door?The BWF Fire Door Alliance states the term usually refers to a fire door leaf which is the main component installed into a fire-rated frame, along with ‘essential ironmongery’ to make the door perform correctly in the event of a fire.However therein is the challenge – when not required to be a fire door it must still perform everyday functions of providing safety, security, privacy, separating different areas and reducing noise in a building.When an architect specifies door products, it is imperative that as well as achieving the everyday design requirements, factors relating to fire resistance are also a key consideration in order to achieve regulatory compliance.Under the spotlightApart from the frame and door leaf, a fire door includes a door closer, smoke seals, hinges, push pads or handles, signage, and maybe a vision panel. Each and every component must be fit for purpose; should any component fail then the whole fire door assembly could fail. And any item that is badly fitted or wrongly specified could contribute to the spread of fire.For each part of the fire door there are standards that must be adhered to.The door and frame should be installed securely and plumb and true with a maximum gap of 3 mm to all sides for a fire door with smoke protection (for a general fire door the gap can be up to 10 mm).The door closer is an important part of the fire door assembly and it is critical to specify a suitable unit and ensure minimum size EN 3 is used.All doors must be fitted with intumescent seals – they play a major role in fire safety as they will expand to around 10 times their volume when significant heat is applied.Hinges are a critical part of a door, carrying its weight and allowing free movement of the door leaf but also helping to keep the door straight during a fire episode. There should be three hinges in a fire door up to 2,100 mm high. For doors over 2,100 mm high, exceeding 150 kg, or over 100 mm wide there should be four. All hinges for fire doors should be made of steel or stainless steel and have a melting point of no less than 800°C.All relevant push pads, handles and kick plates must have the required test data and standards and should have a melting point of at least 800°C. Locks need to comply with BS EN 12209 and lever handles with BS EN 1906.Signage on a fire door is required, such as ‘Fire Door Keep Shut’ or ‘Fire Door Keep Locked’. They need to conform to BS 5499: ISO 7010.Vision panels can be introduced to a door specification for reasons of safety, aesthetics, or to allow transfer of light, however the relevant seals must still be used so as not to compromise the integrity of the fire door and only suitable fire tested glass should be used.Specifying a closer for a fire doorThere are four main types of closer – surface mounted with link arm, surface mounted with guide rail, concealed, and floor mounted closer. All should be tested, approved and certificated to harmonised standard EN 1154, BS EN 1634-1 and have Certifire or similarly approved testing. In addition, a closer should be CE marked or hold the new UKCA (UK Conformity Assessed) certificate (effective fromJanuary 2023).There is also the application to consider: which closer is best suited to the door type, size, location and intended use of the door? Another consideration is the best fitting arrangement, and again this is dependent on door type, size, location and use.There are several different configurations for a variety of applications that also need to be taken into account including fitting configurations, using brackets, mounting plates or spindle extensions to overcome specific site details. All should be specified in accordance with test evidence.Another consideration is being able to adjust the closer. The correct adjustment of the closing force is needed to ensure it meets the requirements for access under Part M and BS 8300 with Part B of the Building Regulations for fire as well. Correct adjustment refers to electro hold open, back check, closing speed, and latch action to ensure the door opens and closes safely and securely.All door closers complying with EN 1154 will have a six figure classification which should be marked on the door closer.The power of door closers according to the EN 1154 standard are rated from one to nine, for example a size three door closer has a closing force of 18 Nm (Newton Metres), where Nm is the closing force exerted by the door one metre from the hinge point. It should be noted that the minimum size allowed for any door closer on a fire door is size three.In summary, while all the component parts of a fire door must be thoroughly tested and conform to all relevant standards, the most important aspect is that they must work together as a doorset.Richard Richardson-Derry is national specification manager for GEZE UK

Accessible for every visitorThe landmark £78 million Darwin Centre is the most significant development at the Natural History Museum since it moved to South Kensington in 1881. With over four and a half million visitors passing through its doors every year, choosing the right door products was crucial if this popular tourist attraction was going to stand the test of time.dormakaba’s contribution to the projectdormakaba TS 92, TS 93, and ITS 96 cam-action door closers were specified due to their low opening forces in accordance with BS8300 and their aesthetical design, which is in keeping with the overall style of the Darwin Centre. The TS 92 and TS 93 cam-action closers have been installed with the electro-magnetic hold-open feature and have been designed to remain open, closing automatically if the fire alarm is triggered. Offering the illusion of an invisible closer, the ITS 96 is a concealed cam-action closer hidden within the door leaf and frame, complementing the overall modern and sleek design of the new centre.As part of the brief, a wall of glass was to surround the technology and displays within the Darwin Centre, only accessible by staff through glass doors. Due to the small diameter between the wall and the glass door, specialists in glass interior products, Harbrine, overcame this by using dormakaba’s EA pinch free patch fitting which allowed safe access with a clear view of the museum display.dormakaba BTS 75V and BTS 80 floor springs also feature at the redevelopment. These floor springs feature a hydraulically controlled closing cycle, adjustable closing speed and mechanical backcheck.Also installed is dormakaba’s ED 200 – an automatic swing door operator that offers an optimum solution for safety in high traffic areas. During an emergency, fire doors and exit doors must continue to open for people to exit, but close firmly to prevent the fire or smoke spreading. The ED 200 is particularly appropriate for internal fire door applications and has been successfully third party fire tested to EN 1634-1 on timber doors. Its unique package of safety, security and interfacing features means that when a fire alarm is actuated, or when the power is cut, the closer will revert from automatic to manual operation with a hydraulically dampened spring close action.
