The NCCTL is for use in an exterior masonry skin in conjunction with a non-masonry inner leaf such as a steel frame system.
A non-combustible stainless steel single-leaf lintel with combined cavity tray.
All Keyfix Non-Combustible Cavity Tray Lintels satisfy the thermal performance requirements of Approved Document L of the Building Regulations (E & W), Northern Ireland’s Technical Booklet F, and Scotland’s Technical Handbook, section 6. The NCCTL satisfy fire safety requirements of Approved Document B of the Building Regulations within buildings over 11 m in height.
Reaction to fire classification = A1 (non-combustible) in accordance with BS EN 13501-1 as defined in 96/603/EC. Meets the requirements of material/coating specification requirements within PD6697. The patented NCCTL prevents thermal bridging. Keyfix's NCCTL conforms to the requirements of a cavity tray satisfying the NHBC & LABC Warranty technical guidance.
The NCCTL patented mechanically fixed Stop Ends are prepositioned within perpend joints to accommodate brickwork openings. The installation of the NCCTL requires no additional specialist skills. The ease of installation in the outer leaf combines the structural load-bearing lintel with the advantages of a self-supporting cavity tray.
