Trilite GRP is Brett Martin's standard and reinforced range of GRP rooflight sheeting with options which meet or offer significantly greater safety margins than the minimum standard.
Correctly specified Trilite GRP 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 Technical Document NTD03.
These rooflights are most commonly used as multiple skins in structures clad with profiled metal or fibre cement cladding where little or no roof access is required after installation, or in the case of reinforced sheets, where roof access after construction is regular.
Trilite GRP sheets are supplied as standard with the ‘Superlife’ enhanced UV protective finish to minimise the harmful effects of the suns’ ultra-violet radiation and to ensure a long life span.

A cost-effective 1.8kg/m2 sheet which can achieve Class B non-fragility when used in combination with Trilite 24 and above.
A standard weight 2.4kg/m2 sheet suitable for projects that will require minimal roof access. It can achieve Class B non-fragility in combination with other GRP rooflight sheets and will also achieve Class C non-fragility during construction when used as a liner in a typical liner profile.
A standard weight 3.0kg/m2 sheet that in typical applications is resistant to damage during construction and suitable on projects where there is limited or controlled access needed after construction. It will achieve Class B non-fragility as a liner during construction or as a single skin rooflight when new.
A heavyweight 3.6kg/m2 sheet that also provides significantly greater safety levels than the minimum requirements and suitable for projects that require regular roof access after construction. It can be expected to remain Class B non-fragile as a single skin rooflight for at least 25 years.
A heavyweight 4.5kg/m² sheet that provides significantly greater safety levels than the minimum requirements and is unaffected by loads typical of inadvertent foot traffic or a falling person when fully fixed. It is ideal when there is a high risk of accidental foot traffic during subsequent roof construction when fully fixed.
Trilite 45 Liner
A heavyweight lining panel with a weight of 4.5kg/m2 that provides generous safety margins at the lining out phase, for safer working conditions. It has a life expectancy of over 30 years.
