Keyfix began with an idea to set up a Brickwork Ancillaries Company and quickly branched into the world of non-combustibility on the back of the new Doc B fire regulations and an interesting conversation with Barratt’s which fanned the flames of innovation even further.

Through many industry conversations with leading Architects and Brickwork Contractors and in conjunction, BRE, BBA, NHBC, Premier Guarantee and LABC Warranty, we went on to develop and patent unique non-combustible solutions. These has been very well received by Installers and Main Contractors as the easiest to use and best customer service option on the market.

Whilst Keyfix has been quick to innovate, we have not compromised on quality or performance and have developed unique and commercially viable, rapid-build solutions that are simple to understand and easy to install.

Keyfix have been recognised and won awards nationally and internationally for our innovative approach to product design and we focus on collaborating with the industry to develop products which solve common problems on-site whilst enhancing long-term building performance.

Our extended range of non-combustible solutions include non-combustible cavity trays, corner units, pier units, stainless steel non-combustible weep vents, non-combustible cavity tray lintels and non-combustible retaining discs.

Technical Expertise

We provide comprehensive technical support on your project and work to meet your every need.

The Keyfix Technical team provide Keyfix clients with the full service package. Our team will attend all design meetings, providing you with a full technical review of architect’s drawings. From this, the team will provide a comprehensive Mark-up with a scheduled breakdown of component locations. Then, when you’re product has arrived and is ready for install, a member of our team will come to site and provide a Tool box talk prior to the first install.

The earlier you contact our engineers in your project the more design flexibility you will have for the overall project. Ask for a Keyfix Engineer to visit your site or office.

Regulatory Response

The introduction of Buildings Regulations Document B (Fire Safety) 2019 was an initial regulatory response to incidents involving the spread of fire within external cavities on tall buildings and prohibit the use of combustible materials within the external cavities of buildings over 18m in height.

The regulations apply to buildings containing one or more dwellings; an institution; or a room for residential purposes. As of June 2022, the Regulations also apply to hotels, hostels and boarding houses.

The amendments to the Approved Documents provide the further guidance (12.10 Note 2) that “materials achieving limited combustibility cannot be deemed to meet the requirement using an alternative classification method.
