Powerdaylight Ø 35 cm dome lens

Powerdaylight Ø 35 cm dome lens

To further enhance the performance and durability of our Powerdaylight system, we incorporate an additional dome lens at the top. This extra lens ensures a fully sealed exterior for optimal weather resistance. It also enables the mirror to be positioned deeper within the tube, maximising light capture and minimising obstruction from northern light reflections. Moreover, the secondary lens significantly improves thermal and acoustic insulation, contributing to a more energy-efficient and quieter indoor environment.

The dome lens of the Powerdaylight is always made from Vivak® UV thermoplastic copolyester. They offer high impact strength, a good fire rating and good weather resistance. These properties are demonstrated by our 10-year guarantee on mechanical strength and optical properties.
