Resistance to Weathering Rooflights

FILON reinforced GRP rooflights are supplied with a highly durable protective film to the weather surface. This extends sheet life and will reduce yellowing. Under normal atmospheric conditions the life expectancy should be in excess of 30 years.Independent accelerated weathering tests completed under ISO 4892 and EN 1013-1 1997, confirm that FILON reinforced rooflights meet the highest durability classification under this standard.
