Where These Kits Are Used

This 450g kit is ideal for:

1. Roofs requiring regular foot traffic or maintenance
2. Balconies being finished with tiles or decking
3. Long-term waterproofing for domestic and commercial flat roofs

Why 450g Matting?

Our 450g fibreglass matting provides:

1. Superior durability
2. Full resistance to weathering
3. Long-term performance under foot traffic
4. Flexibility against structural movement

When installed correctly, a 450g GRP roof offers a lifespan of 50+ years with zero maintenance.

Combine your kit with one of our fibreglass roofing tool packs — each includes enough 50mm tape to complete your roof, so you only need to purchase trims separately.

1. Larger GRP Roofing Kits are available upon request.
