Keystone Lintels’ innovative Non-Combustible Cavity Tray Lintel (NCCTL) has recently been awarded third party certification by the British Board of Agrement (BBA) reinforcing its position as a compliant, commercially viable and installer-friendly solution for modern housebuilding.
Independently certified by the BBA, the NCCTL has been designed to meet the requirements of Building Regulations Approved Document B. Class A1 fire-rated and manufactured from high-grade 304 austenitic stainless steel, it combines the load bearing capabilities of a lintel along with the combined functions of a cavity tray with mechanically fixed watertight stop ends.
The NCCTL was developed as a commercially viable, rapid-build solution that is simple to understand and easy to install. Its ‘Fix & Forget’ self-supporting, single-piece tray allows for fast, easy, single-handed installation with no additional fixings, sealants or onsite fabrication required by the housebuilder. Crucially, the installation of the trays will not impede the speed of bricklaying when compared to any traditional DPC.
The unique design of the stainless steel trays provides watertight protection across the cavity thanks to an interlocking upstand which requires no tapes or sealants to create a waterproof joint. By eliminating the use of sealants at joints, the possibility of installation errors caused by onsite conditions have been removed. The result is a robust, durable and simple to install solution that is designed to last the lifetime of the building.
Commenting on the certification, Jonathan Fee, Technical Director of Keystone Lintels said: “This BBA Certification is an important milestone that is testament to the quality, safety and reliability of our NCCTL solution. This product not only meets the highest standards of compliance but it has also been developed to support fast and efficient housebuilding, with minimal disruption on-site.”
With its newly awarded BBA Certificate, the NCCTL now offers verified performance assurance which is recognised by building control, government departments, architects, local authorities, specifiers, and industry insurers such as the National House Builders Council (NHBC).
