Weight type
FILON GRP rooflights may be used in single skin and double skin applications, and, where necessary, including insulating intermediate layers to provide improved insulation levels for compliance with current legislation. Our rooflights are available in weight types (with nominal weights):
- CE18 (1.83kg/m²)
- CE24 (2.44kg/m²)
- CE30 (3.06kg/m²)

Fire resistance
FILON rooflights have been tested in accordance with BS 476 parts 3, 6 and 7, BS EN 13501 part 5, and BS 2782-0 Annex B Method 508A and are offered in three fire retardant grades:
- Filon Grade 300 – SAB, Class 3, BROOF(t4)
- Filon Grade 104 – SAA, Class 1, BROOF(t4), TP(a)

Colour
FILON rooflights are most commonly supplied as natural translucent GRP sheets. Colour tints can be offered in almost any colour, and as more colour tint is added, the sheet becomes semi opaque and eventually opaque in that colour. Opaque sheets can be used for many applications including the repair / replacement of asbestos cement roofs, as permanent cladding, and also in corrosive environments where steel sheeting would be unsuitable. See our Citadel page for more information.
Added extras
Sheets for external applications are supplied complete with FILON Protect, a highly durable UV resistant polyester film, factory bonded to the weather face. This extends the durable working life of the sheet and the UV resistance limits sheet yellowing.
Other surface protections are available, such as Filon Protect Antiglare which has a matt surface to remove the normally shiny appearance of UV surface protection. This is ideal for opaque sheets but can also be useful in certain rooflight applications. Filon Citadel Plus provides a greater period of protection compared with Filon Protect and is typically supplied with Filon Citadel sheets.
