Add Rooflights
Replace roofing sheets with translucent rooflights to bring natural light into your building.
PLEASE NOTE: when selecting a rooflight this will replace one of your roof sheets.
Allowing natural daylight into a sheeted building can be achieved effectively by replacing selected metal roofing sheets with GRP roof lights. These translucent panels are designed to integrate seamlessly with existing roof profiles, providing a durable and weather‑resistant solution that brightens interior spaces without relying solely on artificial lighting. By strategically positioning GRP roof lights, you can improve visibility, reduce energy consumption, and create a more pleasant working environment throughout the building.
