Fibreglass (also called fiberglass or GRP) is a strong, lightweight composite material made from fine glass fibres combined with resin. It’s widely used in construction, roofing, marine, and industrial applications because of its durability, corrosion resistance, and versatility.
Fibreglass—also known as glass-reinforced plastic (GRP)—is formed by combining glass fibres with resin to create a tough, durable composite material.
This combination results in a material that is:
This makes fibreglass ideal for demanding environments like construction, marine, and industrial settings.
Fibreglass is widely used because it outperforms many traditional materials.
In construction, this means longer lifespan and reduced lifecycle costs.

Fibreglass stands out for its balance of strength, durability, and low upkeep.
Different types are engineered for specific uses:
Choosing the right type depends on your environment and application.
Fibreglass is manufactured in different forms depending on use:
Each form serves a different role in manufacturing and construction.
Fibreglass is used across many industries:
Fibreglass is commonly used in flat roofing systems, where durability and waterproofing are critical.
Compared to traditional materials, fibreglass roofing:
There are three main manufacturing processes:
Each method is chosen based on scale and product requirements.
Yes—fibreglass is highly water-resistant, making it ideal for roofing and marine use.
In terms of strength-to-weight ratio, fibreglass can outperform steel in certain applications.
Fibreglass can last decades with minimal maintenance.
Initial costs can be higher, but long-term savings come from durability and low maintenance.
When selecting fibreglass, consider:
The right choice ensures performance and longevity.
