Ready to install double skin factory assembled Insulating Rooflights are available in GRP, Polycarbonate and PVC.  They are ideal for flat and low pitch roofs.

Unlike some manufacturers, the Brett Martin FAIR incorporates a number of design features which ensure its reputation as the best rooflight of its type available - design features that provide real benefits on site during installation for the contractor. These features

  •  Eliminate many of the common problems of leaking fixing seals and cold bridge condensation problems associated with inferior FAIR designs.

  • Enable the contractor to "fix and forget" whilst delivering real time/cost benefits on site.

   KEY DESIGN FEATURES.

  • 1 mm thick galvanised steel plate at intermediate purlin/filler positions.

  • Optional aluminium strip in underlap.

  • Inclusion of high density foam fillers throughout.

  • Bespoke design to customers exact specification.

  • Incorporates Trilite Superlife weather sheet as standard.

  • Safe system FAIR's with additional reinforcement in weather sheet and lining panel.

   BENEFITS.

  1. Secure seal between high thread fastener and rooflight.

  2. Prevents crushing of foam fillers during installation of fillers.

  3. Standard stitching screw can be used to give secure seal between metal overlap to rooflight or between adjacent rooflights.

  4. No need for expanding grommet. Laplox fixings result in less components on site.

  5. Strong, reliable joint improving seal between GRP and metal.

  6. Elimination of risk of cold bridges and condensation.

  7. Ensures quick easy site installation reducing time and costs.

  8. 30 years life expectancy.

  9. UV protected weather sheet.

  10. None fragile 'safe' FAIR's to meet HSE guidance and CDM regulations.

  11. FAIR's to satisfy site wind/snow load calculations

TECHNICAL INFORMATION

MATERIAL. Trilite translucent GRP Rooflight sheeting, manufactured from polyester resins contains UV inhibitors, fire retardants and processing additives with a fibre glass reinforcement and protective polyester film bonded to both surfaces.

FUNCTION. Trilite FAIR's admit diffused daylight, provide energy conservation and reduce condensation.

WEIGHT. Standard weight 1.83kg/m2 and or 2.44kg/m2, normal weight (and 'AR' advanced reinforced sheet) available as specification or application conditions dictate. Wide purlin spacings, high wind loads and CDM Regulations are determining factors.

LENGTH. Rooflights are manufactured to individual lengths requirements subject to limitations of transport and handling. In practice lengths in excess of 10 metres are to be avoided.

THERMAL CONDUCTIVITY (K)  0.15 W/m deg. C.

THERMAL TRANSMITTANCE (U-VALUE)  Double skin rooflights 3.3 W/m2 deg. C.

LIGHT TRANSMISSION.  Natural translucent Trilite: double skin rooflights approximately 65%.

FIRE PERFORMANCE. Available in fire ratings  of  Class O, Class 1, Class 2, & Class 3.

LIGHT DIFFUSION. Natural translucent Trilite Classification II - Moderately Diffusing Opal White tinted. Trilite Classification IV - Very Heavily Diffusing.

SHADING COEFFICIENTS. Natural translucent Trilite 0.83: Opal White tinted Trilite 0.51.

FIXING.  Extensive guidance is given in BS5427 - 1976.  Detailed fixing information is available from BRETT MARTIN ROOFLIGHT GUIDES.  All transit tape and packing should be removed from the rooflight unit prior to installation.

EFFECTS OF TEMPERATURE. Trilite does not soften at high temperatures or become brittle at low temperatures and may be used in situations where temperatures are in the range of -40 deg. C to +80 deg. C. Some discolouration may occur at temperatures above 65 deg. C but this will not significantly affect transmitted light.

BIOLOGICAL.  Resistant to micro-organisms, fungi and insects. Cleaning with mild detergent solutions will remove organic materials.

CHEMICAL RESISTANCE.  Trilite rooflights are resistant to a large number of chemicals: exceptions are strong solvents and concentrated acid and alkali solutions. For advice on specific chemicals and concentrations refer to the manufacturers.
