Double Layer 450gsm GRP Fibreglass Roofing Kits — Built for Balconies & Walkways

Available from 5m² up to 50m², our Double Layer Balcony & Walkway Fibreglass Roofing Kits are engineered for surfaces that demand the highest level of strength, waterproofing, and durability. Whether you're waterproofing a balcony, terrace, flat roof walkway, or any area subject to regular foot traffic, this is the kit built for the job.

We've been supplying and installing GRP fibreglass systems for many years — we know what works, and this double layer system is our go-to recommendation for balcony and walkway applications where performance cannot be compromised.

Why Double Layer?

A double layer application using 450gsm fibreglass matting provides significantly enhanced tensile strength and waterproofing integrity compared to a single layer. It's the professional standard for balconies, walkways, and any surface exposed to regular movement, thermal cycling, and the elements.

  • āœ… Superior strength and crack resistance
  • āœ… Excellent waterproofing — no joints, no seams, no leaks
  • āœ… Handles foot traffic and structural movement with ease
  • āœ… Long-lasting protection — 50+ year lifespan when correctly applied
  • āœ… Can be applied from as low as 5°C — suitable all year round

Optional tool kits are available — select from the drop-down above if required.

Key Details

  • āœ… Full installation instructions provided
  • āœ… Kits available from 5m² to 50m² — larger sizes available upon request
  • āœ… Catalyst provided at 2% Standard Cure
  • āœ… Suitable for DIY and professional installers

Don't forget your trims — edging trims ordered alongside a full roofing kit are available at just Ā£11 inc VAT. Click here to select your trims.
