Naturalight polycarbonate pyramid rooflights are designed to be a smart, robust and reliable method of allowing natural light into a room. Available in a range of colour tints (clear, diffused, opal and bronze) they can be made to suit customer specifications. They are manufactured using a thermoforming process in single, double, triple and quadruple skin construction, allowing the rooflight to meet architectural requirements.

Double skin – 2.6 wm2k
Triple skin – 1.8 wm2k
Quad skin – 1.4 wm2k

Light transmissions:
Clear 87% – a high light transmission
Allows full vision of views and objects/Minimum privacy
Diffused 84% – a high light transmission
Increased privacy/Reduced glare and shadows
Opal 50% – a low light transmission
Maximum privacy/Reduced glare and shadows/Prevents vision of views and objects
Bronze 50% – a low light transmission
Reduced solar heat gain/Cuts down the brightness of sunlight

Solar gain:
The solar gain (‘g’ value) can be improved to a more manageable level by way of introducing varying tint interlayers to the polycarbonate rooflight construction thus reducing the heat build up occurring from transmittance through the rooflight area

Typical airbourne sound reduction for a triple skin rooflight is 30-35db

Fire rating:
Products comply with current uk building regulations covered under BS476 and european standards covered under BS EN 13501
