The Centre for Window and Cladding Technology (CWCT) is a publisher of standards and guidance only (not regulations), on corrosion, intrusion, fenestration, weather and fire resistance, acoustic and impact performance, of building envelopes, facades, cladding and glazing.
Founded in 1989 and based in Bath, Somerset,[1] the CWCT provides training and courses, hosts international events, conferences, seminars and is recognised by over 330 member companies within the construction industry.
[2] TN98 (supersedes previous technical note TN73) Guidance for the fire performance of facades (including cladding) and suggests that any buildings with compartmented floors will limit spread of fire, thus affecting the design of interface points where the compartment floors meet the façade.
The specific fire strategy for the building, will be set out by the fire engineer including the requirements for the façade cladding.
The fire performance of the cladding and façade should form a key part of the early in the design process and fire strategy.
