GRP Rooflights

Natural light can be introduced quickly and effectively into any building with the use of GRP rooflights. Whether installed into roofing or cladding systems, translucent GRP sheets transform darker internal spaces into brighter, more usable environments — improving working conditions and overall visibility without increasing energy demand. This makes them a simple but highly effective upgrade for agricultural, industrial, and commercial buildings where light and usability matter.

GRP rooflights provide a consistent and even spread of daylight across the internal space, helping to reduce reliance on artificial lighting throughout the day. By allowing high levels of natural light transmission, they can significantly lower electricity usage while creating a more comfortable and productive environment. In many applications, this improved light quality has a direct impact on day-to-day operations, making internal spaces feel more open, safer, and easier to work within.

Manufactured with a UV-stabilised, weather-resistant surface layer, GRP rooflights are designed to maintain performance and clarity over time. This protective finish helps prevent discolouration and degradation, ensuring long-term durability even in exposed environments. With up to 90% light transmission available, they deliver excellent daylight performance while remaining fully compatible with surrounding roofing and cladding sheets.

A wide range of profiles are available to suit both modern builds and refurbishment projects. We stock large volumes of the most common profiles including Big 6 fibre cement, 32/1000 box profile, 34/1000 box profile, and 13/3 corrugated, alongside a variety of obsolete and harder-to-source profiles. This ensures accurate matching with existing roofs and cladding systems, reducing installation issues and saving time on site.

GRP rooflights are lightweight, easy to handle, and straightforward to install, making them a practical choice for both new builds and replacements. Installation guidance is readily available to support correct fitting, helping to ensure long-term performance. All products are backed by a 10-year manufacturer guarantee, providing confidence in their reliability and lifespan across a wide range of applications.
