Cost-effective Filonite GRP sheets are ideal for a wide range of roof glazing applications, including car ports, garage roofs, covered walkways, lean-to's garden sheds and workshops. Filonite is a clear lightweight GRP sheet, available in two profiles: Filonite S with a Sinusoidal profile and Filonite T, with a trapezoidal profile. Both sheets offer an exceptional 94% light transmission to give maximum light where you need it. Building Regulations allow Filonite to be used as follows: Complete roof of domestic garages and outbuildings of maximum 40m² area. Open sided buildings such as balconies, carports, coveredways and canopies that have one longest side permanently open. Benefits Durable: A long, maintenance free life of 20 years plus can be expected with Filonite. Low Maintenance: Only occasional washing of the external surface is required to maintain the best levels of light transmission. Fire resistant: Independent tests under BS476 ‘fire tests’: Parts 3 and 7 confirm Filonite sheets have been designated AB and rated Class 3.
