A quick wipe down every now and then will keep them looking as good as the day they were installed.
Composite GRP doors are made from a very smart material called glass-reinforced plastic, or GRP. This is a particular type of plastic that has been reinforced with fine glass fibres. The result is a lightweight material with incredible strength and resilience. Perfect, in other words, for a strong, hardwearing door that combines good looks and elegance with all the protection you need. Because of its unique durability, those good looks will last for years to come.
