Rooflights – Going Round In Circles

A new circular-glass rooflight from Brett Martin Daylight Systems is said to maximise daylight and exceed the thermal performance requirements of building regulations approved document L.

It is available in four standard sizes ranging from 600mm to 1,500mm and bespoke sizes. It can be mounted direct to a builder’s upstand or with a robust prefabricated insulated GRP kerb for both new build and refurbishment applications, which can reduce onsite installation time and cost.

It will hit an overall U-value of between 1.16 and 1.64 W/m2K depending on size and configuration.

The unit comprises a double-glazed panel encased in an environmentally friendly RAL 7016 powder coated aluminium frame. All frames are thermally isolated to minimise the risk of condensation.

 

Safety

It benefits from a laminated inner pane for the safety of those below and is also non-fragile for the safety of those above, having been successfully tested to CWCT TN-67 for class 1 roofs and Class B to ACR[M]001.
