The Keystone Non-combustible Cavity Tray Lintel offers a non-combustible stainless steel single leaf lintel with combined cavity tray.
For use in an exterior masonry skin in conjunction with a non masonry inner leaf such as a steel frame system, the NCCTL is a highly efficient and practical solution to the challenge of non-combustible cavity detailing. Manufactured in Class A1 grade 304 austenitic stainless steel, the NCCTL represents the ideal specification for all applications requiring Document B compliance. The NCCTL can also be ordered in grade 316 austenitic stainless steel if required in coastal locations.
- Non-combustible Class A1 for compliance with Document B in buildings over 11m high
- Stainless steel construction with mechanically fixed watertight stop ends
- Facilitates speedy installation
- Utilises traditional onsite trades, no additional skills required
