Dome and Pyramid Rooflights

Polycarbonate domes and pyramids are available in a range of standard sizes and configurations fitted with single, double and triple layers of polycarbonate glazing.

They can be ordered with or without an insulated kerb and can be fitted to existing or new builders' kerbs. Manual or electric opening can be provided for fresh air ventilation and controllable trickle ventilation is an option. Access hatches and smoke vents can be supplied in a range of sizes.

All Twinfix domes and pyramids use the same Marlon FS Longlife, premium quality polycarbonate with a co-extruded UV protection, that eliminates 98% of harmful UV radiation.

Marlon FS Longlife has an impact resistance of over 200 times that achieved by the same thickness of glass.
