What is GRP/Fibreglass Roofing?

GRP Roofing or as it’s full term ‘Glass Reinforced Plastic’ commonly also known as Fibreglass is constructed from a polyester resin, which is then strengthened by chopped strand mat glass fibres to form a laminate. In roofing, this provides a strong yet lightweight alternative to lead roofing, providing a strong, durable and weatherproof material perfect for flat roofs.  

When was GRP/Fibreglass Invented?

The material was first invented in 1938 by Russel Games, affectionately known as the ‘Father of Fibreglass’  In the early days, fibreglass - which was also known as ‘Glass Wool’ had a massive array of uses, it was used in the construction of boats - as well as used as a form of building insulation.

Technological advances since the 1930’s has seen GRP one of the most commonly used materials in the worldwide construction industry.
