GRP Roofing Sheets
Frequently Asked Questions
What is GRP (Glass Reinforced Plastic)?
GRP is essentially a plastic polymer that has been reinforced with strands of glass. These strands are incredibly fine and woven together to form a fabric-like material. When combined with a plastic polymer, this eliminates the danger glass usually poses whilst increasing the strength of the end product.
This material can be found in a variety of products, such as stair tread and roofing sheets. This is due to the impact resistance, thermal insulation, and other properties of GRP. It is also incredibly long-lasting and cost-effective when compared to other materials.
When buying GRP roofing sheets, you may see them referred to as fibreglass sheets. Despite the name difference, they will usually be manufactured from the same materials and offer the same advantages. You can learn more about GRP by clicking here.
How Strong is GRP?
The uses of GRP or fibreglass are almost endless. This is due to the durability the material offers whilst remaining lightweight. This makes it ideal for a variety of manufacturing and construction applications, such as roofing.
By combining plastic polymers and glass fibres, GRP is able to withstand ultraviolet light and high temperatures. It is also resistant to many chemicals and salt air. This virtually eliminates the chance of corrosion.
The biggest advantage of GRP roofing sheets is their impact resistance. Whether you struggle with severe weather or falling debris, this material is often able to protect your property from these dangers. Making it ideal for rooflights or canopies.
What is the Difference Between GRP and PVC?
Whilst PVC and GRP look similar, they are actually very different. PVC is usually produced from a plastic polymer alone. GRP, on the other hand, also features glass fibres throughout. Therefore increasing its overall strength.
It is important to remember that GRP will not let the same level of daylight through. This is again due to the glass fibres reducing transparency. GRP rooflights may, therefore, appear 'misty' once installed.
