Corrugated rooflights are rolled using a composite material known as glass-reinforced plastic (GRP), which is also known as Fiberglass in the US. This fibre-reinforced polymer roofing sheet is reinforced by fine fibres made of class, which also make the material transparent, allowing light to pass through. This makes it a perfect composite for rooflight roofing sheets, as they have the strength required, whilst allowing light into the building from outside.
The benefits of usign GRP/fibreglass for roofing sheets include:
- Has a good weight to strength ratio
- Is corrosion resistant
- Is water resistant
- It is light-weight
- Is non-conductive
