Level Threshold Approach has Problem Covered

Level Threshold Approach has Problem Covered

Cavity Trays Ltd

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.

Controlling Penetrating Water in Cavity Walls

Controlling Penetrating Water in Cavity Walls

Cavity Trays Ltd

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.

IntroductionThe Keyfix Non-Combustible Cavity Tray System has played an important role in futureproofing a major new residential development in Stratford’s Olympic Park by exceeding new building regulations whilst improving build quality and installation efficiency on site.OverviewLocated in the very heart of the Queen Elizabeth Olympic Park, Chobham Manor in East London is the first of five new neighbourhoods in the former home of the 2012 Olympics. Comprising 850 new one, two and three-bed homes alongside community facilities, shops, public green spaces and community areas, this stunning new development has sustainability at its core with all homes built to the Code for Sustainable Homes Level 4.In a design by JSA Architects and built by Taylor Wimpey, the layered brickwork façade features projected bay windows, balconies and set back terraces. To meet the requirements and a tight build programme, Keyfix worked with subcontractor Chine Brickwork and supplied 4545 metres of Keyfix Non-Combustible Cavity Trays (NCCT) along with Corner Units and Weeps on blocks A, B and C which form Phase Four of the development.ChallengeThe challenges for Keyfix were the unique brickwork build programme which incorporated two runs of cavity trays being supplied per floor to accommodate brickwork corbelling and recessed brickwork.SolutionAs the corbels where built at a different stage on the build programme so the Keyfix Non-combustible Cavity Trays had to project out either side of the pier when initially being installed. Therefore, when the infill corbels where being built the continuous run of tray could link in seamlessly. A task that would have been near impossible had the system relied on tapes or mastics to make the linking joint.The Keyfix stainless steel NCCT was specified due to its self-supporting system which doesn’t need fixing back to the internal concrete frame and clips together for fast and easy installation. It is essentially a ‘Fix & Forget’ solution with no additional fixings, sealants or onsite fabrication required by the brickwork contractor. Therefore, installation of the trays did not impede the speed of bricklaying even when compared to traditional DPC. Installed in the outer leaf with no connection with the inner skin, this innovative cavity tray system does not create a thermal bridge and eliminates all differential movement issues.With a lifespan of 125+ years it is the only non-combustible cavity tray system that does not rely on tapes and mastics to make watertight joints, therefore elimating one of the main reasons for product failure.Commenting Kieran Coyle of Keyfix said: “Holding an A1 Fire Rating, the Keyfix non-combustible cavity tray solution exceeds the minimum standards set out in ADB (Approved Document B), whilst ensuring this new development meets and exceeds the latest regulations. If the regulations become stricter, it will also be futureproofed maximising the whole-life value of the development.”The award-winning Chobham Manor Phase Four is now complete, with the Keyfix Non-combustible Cavity Tray playing an integral part in the creation of a safe and resilient development that will transform the Olympic Park into a lasting legacy for East London.For more information about the Keyfix range of non-combustible solutions download the product guide, visit https://keyfix.com/or for technical support call 028 8676 7508 or email info@keyfix.com

Verdo-Kew Bridge

Verdo-Kew Bridge

Keyfix

IntroductionThe speed of installation and improved build quality of the Keyfix Non-Combustible Cavity Tray System has played an important part in the construction of a major new high-rise residential development in West London and at the same time help meet and exceed regulatory requirements.OverviewLocated close to the Thames in Brentford West London, Verdo – Kew Bridge is a new mixed use development which forms part of a major new regeneration scheme that includes the new community stadium for Brentford FC. Designed by Broadway Malyan and built by developer EcoWorld, it comprises of 487 new one, two and three-bed homes alongside retail and business spaces, public green spaces and community areas.In order to safeguard the future of the development, Keyfix supplied 765 metres of Keyfix Non-Combustible Cavity Trays (NCCT) along with 2490 Corner Units, 4000 Pier Units and 5000 Weeps on blocks E,F,G and H of the development.ChallengeOne of the key challenges for Keyfix was the brickwork build programme which required early completion at the lower grid line levels of one to six. This was due to the scaffolding needed to be stripped away because it was blocking a walkway at Brentford Stadium and therefore needed to be cleared prior to the start of the new football season.SolutionWorking to a tight schedule, the offsite fabrication and preforming of bespoke non-combustible cavity tray units in line with the brickwork set out drawings saved time for the installation team at brickwork contractor DWG. This one-piece NCCT system allowed for a very simple and very efficient install, enabling the brickwork façade to continue at a fast pace.The Keyfix stainless steel NCCT was specified due to its self-supporting system which doesn’t need fixing back to the internal concrete frame and clips together for fast and easy installation. It is essentially a ‘Fix & Forget’ solution with no additional fixings, sealants or onsite fabrication required by the brickwork contractor. Therefore, installation of the trays did not impede the speed of bricklaying even when compared to traditional DPC. Installed in the outer leaf with no connection with the inner skin, this innovative cavity tray system does not create a thermal bridge and eliminates all issues associated with differential movement.Furthermore, the NCCT is manufactured with integral Stop Ends on each cavity tray to ensure water is trapped and channelled outwards via a Keyfix Non-combustible Weep (NCW). The integral Stop Ends also facilitate perp joint width adjustability of +/- 3 mm between 7–13 mm if required.With a lifespan of 125+ years it is the only non-combustible cavity tray system that does not rely on tapes and mastics to make watertight joints, therefore eliminating one of the main reasons for product failure.Commenting on the project, Kieran Coyle, Keyfix Technical Sales Manager said: “Verdo – Kew Bridge was the first project in which we created and used a Component Schedule and this is now the same component schedule template we use on every project. It allows installers to use new Component Codes to identify the different components and install the system to its full integrity.”Holding an A1 Fire Rating, the Keyfix non-combustible cavity tray solution exceeds the minimum standards set out in ADB (Approved Document B), whilst ensuring this major new development meets and exceeds the latest regulations. If the regulations become stricter, it will also be futureproofed maximising the whole-life value of the development.Set to make its mark on West London, Verdo – Kew Bridge is on track for completion, with the Keyfix Non-combustible Cavity Tray meeting the contractors requirements and enabling the creation of a development that has safety built in.For more information about the Keyfix range of non-combustible solutions download the product guide, visit https://keyfix.com/or for technical support call 028 8676 7508 or email info@keyfix.com

Addiscombe Oaks

Addiscombe Oaks

Keyfix

IntroductionThe Keyfix Non-Combustible Cavity Tray has been installed as part of a new-build project, Addiscombe Oaks in South London, helping to safeguard the development from fire and future building regulation changes.OverviewAddiscombe Oaks is a residential housing development designed by Gardner Stewart Architects (GSA) and developed by L&Q. This new-build development offers a selection of contemporary studio, one, two and three bedroom apartments. Conveniently located in East Croydon, residents of Addiscombe Oaks will benefit from quick transport links into London Bridge, Brighton and Gatwick airport, in addition to nearby shopping centres and parks.Working alongside brickwork contractor Lee Marley Brickwork, Keyfix supplied 2,200 metres of its Non-Combustible Cavity Tray (NCCT), 434 preformed Corner Units, 1,362 preformed Reveal Returns, 8,700 weep vents, as well as Non-combustible Cavity Tray Lintels (NCCTL) over 264 openings.The primary objective for the client was to ensure that the building was constructed in line with updated building regulations, and to ensure that the building would be future-proofed against potential regulation changes. Keyfix was able to meet this objective, as its NCCT is designed to last for the life of the building. The Keyfix NCCT is a fully compliant, A1 fire-rated system, manufactured using Class A1 Non-combustible Grade 304 austenitic stainless steel, resulting in a lifespan of 125+ years for the entire system. Therefore, its use ensures that the building is protected, should building regulations become stricter in the future.ChallengeFurthermore, the main challenge the client faced on the project was keeping to the tight project timeframes. The project ran from October 2021 to August 2022, and the main contractor required an accredited solution which could be delivered in line with the tight-build programme. Keyfix resolved this challenge by supplying products which improved buildability. In particular, the provision of preformed corner units helped to significantly save time on installation.SolutionThe Keyfix NCCT was specified due to its ‘self-supporting one-piece system’ which allows for an easy and efficient installation. The NCCT’s unique design incorporates a stainless steel tray to provide rigid self-support across the clear cavity and requires no reinforcement from the internal structure using mastics or tapes. This design saves precious time for the bricklayer and eliminates clashes with other components.Likewise, the Keyfix Non-Combustible Cavity Tray Lintel was specified due to its A1 Fire Rating, high performance stainless steel, and ease of installation. As the NCCTL requires no tape or mastics, it is a system that allows the contractor to ‘fix and forget’. The design of the NCCTL also incorporates mechanically fixed Stop Ends to capture and channel water outwards via the Keyfix NCW (Non-combustible Weep). The NCCTL is the maintenance-free solution that can accommodate openings up to 2822.5mm, with lintel lengths based on brickwork opening sizes with the range based on 215mm stretcher bond as standard.Moreover, Keyfix supports its clients with the provision of a technical review of architects drawings and a comprehensive schedule and location layout plan on every project. On Addiscombe Oaks, Keyfix engaged with L&Q and Lee Marley Brickwork early on so that any challenges could be resolved before construction took place, ensuring that the project ran smoothly. Keyfix’s team attended design meetings, followed up with calls to site, and provided a Tool Box Talk and CPD webinar presentations to provide technical support and educational resources alongside its products.Martyna Kielbasa, Senior Design and Technical Manager at L&Q commented: “The non-combustible cavity tray was specified as it aligned with the non-combustible scheme throughout the whole development. Keyfix’s representatives supported our subcontractor throughout the construction process by assisting with technical reviews, itemised schedules and sign-offs on specs.”Commenting on the NCCT, Kieran Coyle of Keyfix stated, “The Keyfix Non-Combustible Cavity Tray is an A1 fire-rated system, ensuring our customers peace of mind as their buildings are future-proofed and safeguarded against fire, in addition to onsite efficiency.”Addiscombe Oaks is now complete, with the Keyfix Non-Combustible Cavity Tray system having played an essential role in the construction of a safe residential development that is future-proof against possible regulation changes.

Park East

Park East

Keyfix

IntroductionThe Keyfix Non-Combustible Cavity Tray has been installed as part of a major housing project , Park East in South East London, helping to improve efficiency onsite, and to exceed building regulations.OverviewPark East is a £95 million development in Erith, designed by ECD Architects and developed by Wates Group. The project comprises 320 new homes, of which 20% are for private sale, 24% for Shared Ownership, and 56% for rent in order to accommodate a mixed tenure community. The modern, stylish homes are in close proximity to the local amenities and parks, with excellent transport links to London.Working alongside brickwork contractor Lee Marley Brickwork, Keyfix supplied 3,772m of its Non-Combustible Cavity Tray (NCCT), 3,528 units of corners, and 20,774 units of its Non-combustible Weep Vents to this project. Keyfix’s sister company Keystone Lintels supplied 890m of its Non-Combustible Cavity Tray Lintel, which was powder coated as per the client’s request.Challenge The main challenge faced on this project was the brevity of the programme, which ran from November 2020 to November 2021. As the project was time sensitive, the main contractor required an accredited solution which could be supplied in line with the tight-build programme. Keyfix’s NCCT presented the ideal solution to this challenge.SolutionKeyfix was able to meet the client’s objectives by providing products in accordance with their tight-build programme. To ensure the maximum efficiency of installation, Keyfix designed various types of bespoke units including preformed corners and pier units to assist Lee Marley brickwork in keeping to its the fast-paced build programme. Due to the scale of the project, the products were prefabricated, allowing the brickwork to be conducted swiftly. Despite the bespoke nature of the products, the first delivery was made just two months after the initial enquiry in September.Duncan Marley, Contracts Director at Lee Marley Brickwork commented: “On the Park East development we required various bespoke products and Keyfix were able to provide a quick turnaround on those. The Keyfix NCCT also helped us to save time significantly because the system is so quick to install. Keyfix also provided us with a scheduled breakdown of components which was a great help.”The Keyfix NCCT was specified due to its ‘one-piece system’ which allows for a very simple and efficient installation. The system is self-supporting as it doesn’t require fixing back to the internal frame, therefore saving valuable time. Additionally, the adjustability of the perp joint allows for the cavity trays to be shunted to match the brick coursing on site, ensuring consistency in the brickwork formation.The NCCT was also chosen due to its A1 fire rating. It is made from non-combustible Grade 304 stainless steel which will never contribute to fire loading in the building. This fully compliant system ensures that the Park East buildings will be future-proofed against the implementation of tighter regulations.The non-combustible nature of the product makes it an effective solution to provide DPC protection over lintels, masonry supports, soffit systems and other elements in the cavity such as fire barriers. Additionally, the fact that the Keyfix NCCT does not rely on tape or mastics to form its watertight joints negates the prevalent cause of product failure and creates a more robust system altogether.In addition to providing NCCTs, Keyfix identified where it could offer technical support, and provided a full technical review of architects drawings, a comprehensive mark-up, and a scheduled breakdown of component location. The team also attended design meetings to ensure that the products were being used correctly, as well as hosting a Tool Box Talk prior to the first install to ensure the system was installed properly.Commenting on the NCCT, Kieran Coyle of Keyfix stated, “The Keyfix Non-Combustible Cavity Tray is an A1 fire rated system, ensuring our customers peace of mind as their buildings are future-proofed and safeguarded against fire, as well as our on-site benefits.”The Keyfix Non-Combustible Cavity Tray has played an important part in the creation of a safe new-build development for future tenants to enjoy.

Kingsway Gardens, Residential Balcony Upgrades

Kingsway Gardens, Residential Balcony Upgrades

Garland UK

Kingsway Gardens, located in a leafy suburb of Hampshire, is made up of 5 residential blocks of flats that had been experiencing a large number of leaks across their balconies on multiple levels.The existing asphalt was showing signs of wear and tear with age degradation, where the lack of a full cavity tray, had meant the perimeter upstand had not been sufficiently protected for many years. With many attempts being made to patch the repairs, eventually, the insulation beneath the asphalt had become saturated, severely reducing its effectiveness as an insulator and having a detrimental effect on the U-Value of the buildings.Garland Technical Manager, Paul Boole and Technical Assistant, James Hiscock was instructed by property and construction consultants, The Welling Partnership, to provide their technical expertise and support to survey Kingsway Gardens and propose a tailored waterproofing specification for the residents.

Sotech Ltd

8300 SQM of Optima FC+, Optima FC+ perforated panels and Optima IPC (soffits) have been used in the completion of the 23-storey New Bailey building in Salford Quays.Optima FC+ was selected for a number of reasons on this project.Predominantly, it is an incredibly user friendly system – panels can be quickly and easily adjusted on site and the system can be fixed top down, or bottom up with individual panel removal and replacement. This makes Optima FC+ a highly desirable choice for designers and installers.However, the panels were specifically adapted for this project to enable a completely secret fix system, as per the architects vision. Therefore the top return fold was increased to 50mm instead of 38mm. This allowed for the security fixings to be completely concealed by the panel above, allowing the customer to easily fit the panels from ground up.Optima FC+ perforated panels were chosen as an additional aesthetic feature and Optima IPC was selected for the soffit areas as the architect requested a secret fix system.A bespoke window reveal and bracket was included in the panel design. This allowed for an extended side return which was used to hook on the panels and enable a secret fix. The Optima IPC system was perfect for this part of the design as it enables hidden mechanical fixings and is a cost-effective solution using 2.0mm aluminium.Black PPC aluminium was used as backing trays to enhance the appearance of the perforations, prevent views through the perforations and close off the cavity.Optima FC+ has been independently tested and certified to meet CWCT rigorous specification for rainscreen cladding and has been fire tested to BS8414-2 and classified to BR135 for high rise buildings. This makes it the perfect solution for Plot C1, now the tallest residential building in the New Bailey plot.Plot C1, which features a six-storey podium with an exclusive rooftop garden terrace for the wellbeing of residents, incorporates a number of sustainability measures including surface water drainage attenuation, minimising off site spoil disposal, reduced water consumption.The project has been shortlisted in the 2022 Facade Awards UK for ‘Best use of a rainscreen system using aluminium’.
