Product description
These 2.5mm roof lights are single-skin GRP rooflight sheets that let natural daylight into a building. Made from glass reinforced polyester resin in a neutral translucent finish, they are profiled to match common roof sheeting so they sit flush within a roof of profiled sheets or insulated panels. They are the economical way to bring daylight into halls, warehouses and agricultural buildings.

When to choose this roof light?
The 2.5mm roof light is a single-skin sheet, meaning it provides daylight but no thermal insulation. It is the right choice for unheated buildings or as a daylight strip within a roof of profiled sheets. Where the surrounding roof is insulated and the rooflight should match its thermal performance, an insulated rooflight such as the 40mm GRP roof light or a thicker version is the better fit. A full overview is available in the stock articles and in our clear roofing sheets section.
Suitable Accessories
For installing the 2.5mm roof lights we need or recommend:
- Tek screws with sealing washers, matched to a timber or steel substructure. A selection is available among our screws and fixings.
- profiled filler pieces and sealing tape to close the profile against the adjoining sheets.
- matching roof panels for the surrounding roof area: insulated roof panels.
A full overview of accessories is available in our accessories section.
