Energysaver is an innovative triple skin factory assembled rooflight offering maximum daylight potential, thermal performance and ready-to-fit convenience for wide-span buildings. Delivering U-values from 2.0W/m²K down to 0.9W/m²K, Energysavers help a building achieve compliance with Parts L2A and L2B of 2006 Building Regulations. Energysaver FAIRs have been designed with a transparent internal insulating membrane, Cleartherm, to partition the space within the rooflight and create an additional heat barrier, providing outstanding insulation for minimal extra cost.

Available for GRP Trilite and Trilite Ultra weather sheets: Optional unique ‘Diamond’ long life (standard on Safelight) gives protection against weathering, UV degradation and chemical attack, giving a life expectancy of over 30 years.
Trilite GRP
Standard range of GRP.
- Meets the required safety standard Class B non fragile to ACR[M]001:2005
- Available in weights of 2.4kg/m2 or 3.0kg/m2
- Weather sheets supplied with ‘Superlife’ enhanced UV surface protection
Trilite Ultra GRP
Range of heavyweight sheets offering significantly greater safety margins than the minimum standard.
- Advanced reinforcement provides optimum strength
- Weather sheets supplied with ‘Superlife’ enhanced UV surface protection
- Available in weights of 3.6kg/m² or 4.5kg/m²
Safelight GRP
Safelight is the safest rooflight available, with unequalled safety margins and unmatched rigidity ensuring it will not be damaged by inadvertent foot traffic. Safelight is supplied with ‘Diamond’ long life surface protection as standard, providing optimum weather performance.
- Safelight is supplied with ‘Diamond’ long life surface protection as standard, providing optimum weather performance
- Safelight reinforcement system for best possible strength and rigidity
- Non-fragility can be guaranteed due to minimal reliance on condition of fixings
Marlon CS
Marlon CS Longlife profiled polycarbonate FAIRs provide outstanding impact resistance and co-extruded UV protection to cut out 98% of harmful UV radiation and reduce the effect of sheet weathering. Available in a wide and increasing profile range, clear options provide excellent light transmission and tint options allow solar control.
- 98% of harmful UV rays eliminated to reduce effect of sheet weathering
- Excellent light transmission
- Wide and increasing profile range available
- Self-venting material which softens and opens in the event of a fire allowing smoke, flames and fumes to escape
- Achieves a non-fragility rating without need for additional safety measures
Universal FAIR is a patented option, offering a continuous internal support structure which allows fasteners to be positioned at any point along the length of the rooflight, whilst also ensuring a U-value of 2.2W/m²K is achieved.
The intermediate sheet provides full support at fixing positions, eliminating ‘dishing’ around fasteners, ensuring a weathertight seal is simply and reliably achieved. This concept avoids the need for intermediate HardpakTM fillers, simplifying the ordering process, and is particularly beneficial in refurbishment projects where purlin spacing is not known or variable, or wherever steelwork tolerances are greater than normal.
