Bespoke ridgelights are designed to maximise the amount of natural daylight in a building and at the same time provide a clean, minimalistic finish both inside and outside.

They are manufactured from proprietary aluminium extrusions in a range of sizes to suit slope lengths or design. Available with hermetically sealed glass units, the rooflights are installed on-site, either to a site-formed upstand or to a proprietary Whitesales upstand.

Gable, hip- and open-ended ridgelights are custom-made continuous rooflights which are available in spans of under 1m up to 7m unsupported, and larger with a supporting framework. A 30° slope is designed as standard, although bespoke pitches can be achieved. Each rooflight run is terminated with glazed gable ends, hipped ends, wall abutments or open ends. Bays are designed at equal centres as standard, which will be sized in accordance with the required dimensions and glass specifications. Units can incorporate angles and other specialist detailing.


Glazing is available in polycarbonate, multiwall or solid sheet and single-, double- or triple- glazed glass. Clear, opal-diffused and heat-reflect polycarbonate are suitable for a broad range of projects. Glass is available in an extensive range of options to meet the more demanding criteria. The thickness and type is determined by the size and configuration of the rooflight unit and can be custom designed.
