This Cromar 450gsm fiberglass chopped strand matting is designed for professional roofers and DIY enthusiasts installing a ProGRP roofing system. Its primary benefit is providing structural reinforcement for roof areas that require a reliable, light-duty waterproof base. Note that this matting is specifically calibrated for light foot traffic and should not be used in high-traffic commercial zones without additional reinforcement specifications.

No, the 450gsm variant is designed specifically for light foot traffic. For heavy-duty areas, you should use a heavier grade of matting.
One roll provides approximately 12 square metres of coverage.
While it is engineered for ProGRP systems, it is generally compatible with most standard roofing polyester resins, but testing on a small sample area is recommended.
You should wear gloves, long sleeves, eye protection, and a mask to prevent skin irritation and inhalation of fiberglass dust.
Yes, it is standard practice to overlap the edges of the matting by at least 50mm to ensure a continuous, waterproof seam.
Keep it in its original packaging or a sealed plastic bag in a dry, dark place to keep it free from moisture and debris.
You are likely using insufficient resin; apply more until the fibers appear fully wetted and clear.
Use a metal consolidation roller immediately after wetting the matting to push air out from under the fibers.
Use a sharper cutting tool and handle the cut pieces as little as possible before placing them on the deck.
Before installation, ensure your roof deck is clean, dry, and moisture-free. The matting should be cut to size using sharp industrial scissors or a knife to prevent fraying at the edges. Store the rolls in a cool, dry environment away from direct sunlight and humidity to maintain the integrity of the binding agent. When handling, always wear gloves and long-sleeved clothing to protect skin from glass fibers, and consider using a dust mask to avoid inhalation of stray particles during cutting.
