The system mat — built to wet out fast and lay dead flat.
E-glass chopped strand mat engineered for hand lay-up on roofs: uniform weight, quick wet-out, easy air release, and low resin use. Clean, clear laminates that look right and last.

Why roofers pick it

• Fast wet-out & easy de-airing for pace on deck and detail.
• Excellent weight uniformity for consistent thickness across the field.
• Low resin consumption — saves mix, keeps weight down.
