FILON rooflights are manufactured from glass reinforced polyester resin (GRP), with unique light diffusing additives which scatter light passing through, to provide effective daylighting without hot spots, excessive glare or shadow. They are available in over 900 different profiles, to match all current and most discontinued asbestos cement and metal roofing profiles.
FILON GRP rooflights may be used in single skin and double skin site assembled applications and where necessary, including insulating intermediate layers to provide improved insulation levels for compliance with current legislation. FILON GRP rooflights are available in the various weights types of: CE18; CE24; CE30 and; CE36 respectively with nominal weights of 1.83kg/m², 2.44kg/m², 3.06kg/m² and 3.66kg/m².
FILON rooflights have excellent impact resistance and 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. Under normal conditions, sheet life should be in excess of 30 years.
The FILON standard range of profiled rooflights and sheets is available at sheet types to provide Class C and Class B non-fragile ratings in accordance with ACR(M)001:2014.
FILON sheets are supplied cut to length to suit customer requirements and the widths will be determined by the profile.
FILON rooflights have been tested in accordance with BS 476 parts 3, 6 and 7 and are offered in three fire retardant grades of SAB class 3, SAA Class 1 and SAA1 Class 0. For technical advice on which fire grade should be used in specific applications please refer to FILON Technical Services Department.
FILON rooflights are normally 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 subsequently 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 the Citadel page and literature for more information.
