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.

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
Acoustic:
The typical airborne 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
