The fabric you see at the perimeter of our porch enclosures is Top Gun® (600 denier) acrylic coated polyester. It is a marine-grade fabric available in colors to match and complement your home, that will last for years. Top Gun utilizes an innovative, proprietary process to coat both the top and bottom of the fabric, making it completely reversible and element-proof on both sides. Not your father’s marine canvas, it’s a completely new material featuring excellent strength, durability, tear and abrasion resistance, dimensional stability, UV and mildew resistance. It is attractive year after year, and easy to clean.
