The 12 mil woven poly is suited for even hotter climates, offering 82% light transmission and diffusion, with an optional anti-condensation coating. It is particularly effective in areas experiencing prolonged direct sunlight, providing the most significant reduction in heat retention among our products.

Usage Instructions:

• Measure Width: On your greenhouse frame, measure the full length of Dimension A (the width) along the support beam. We recommend rounding up to the nearest foot and adding an extra foot to ensure a complete edge-to-edge seal. Record this measurement.
• Measure Length: Determine Dimension B (the length) by measuring from one outside end of your support structure to the opposite end. Again, round this measurement up to the nearest foot for precision and ease during installation.
• Ordering: Provide these measurements (Width x Length) to your representative, who will then offer a price quote and estimated delivery time.

Pro Tip for Pricing: Calculate the area of your custom poly by multiplying the width (A) by the length (B) to get the total square feet. Then, multiply this area by the price per square foot to determine the total cost of your custom greenhouse covering. Happy growing!
