The 175mm vertical kerb is an ideal solution for achieving a low rise rooflight sitting at 175mm high, this kerb is vertical which will maximise the available clear light size.
The 175mm kerb also meets building regulations when installing to a cold roof.

The kerb is designed to be fitted to the finished roof level and is, therefore, the ideal choice for retrofitting to an existing roof and then “weathered in”.

Please note that if you choose a wormgear operated rooflight you will require a winding rod to operate, please follow the linked product below.

Unlike adapter kerbs, when taking sizes to choose the appropriate kerb, use the roof opening size.



Our polycarbonate roof lights offer high impact resistance whilst having minimalistic and modern aesthetics, offering a smart solution that allows natural light to fill a room.

This product is available in both dome & pyramid styles, Polycarbonate tints are also available to offer privacy, reduce glare, and also to restrict light transmission.

This kerb is one of the most competitive UPVC products on the market and this range offers a sleek modern design that is part ‘L’ compliant.

Extruded from high-quality UPVC this range offers an integrated water management system to shed water to the outside of the rooflight. internally the white UPVC provides a clean, smart self-finish.

All of our standard kerbs are extruded with a ribbed section to assist with the adhesion of the roof covering (eg felt) above that there is a termination angle to offer a suitable point to end said covering.

A datasheet for this product is available in the resources section of this site.

It is the buyer’s responsibility to ensure the rooflight size purchased is suitable for the intended installation, all rooflights are made to order and are non-returnable.
