Trilite is Brett Martin Daylight Systems standard range of GRP rooflight sheet, meeting minimum required safety standards. Correctly specified Trilite rooflights can generally achieve Class B and Class C non-fragility when new, and are available to meet industry recommendations for non-fragility for 25 years, as outlined in NARM Guidance Note 2006/1. These rooflights are most commonly used in simple, low cost structures where there is little or no roof access required after installation.Trilite sheets are supplied as standard with the ‘Superlife’ enhanced UV protective finish.
