The fabric you see at the perimeter of our porch enclosures is 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. Our fabric is made using 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 remains attractive year after year, and is easy to clean.
