Further to government review and amendments on the requirements for cavity trays, and our internal review of non-combustible trays now available and acceptable to us, we require the following for warranty acceptance:
For all projects commencing after 1st January 2023, LABC Warranty will require cavity trays on residential buildings above 18m to be non-combustible (performance requirement including A2-s1, d0 or A1 reaction to fire classification) and to have independent third-party product certification that has been assessed as being acceptable to us.
Cavity trays should be used in accordance with the product certification and the use of preformed corners must be incorporated.
