Polygal is a fantastic tool to cover pergolas, awnings, patios, and any other outdoor space you can create. It is a durable product that lets light in but blocks UV rays, rain, and, most importantly here in Texas, HEAT! However, improper Polygal installation can damage the product and greatly reduce its lifespan. We have established a list of the top three issues directly resulting from installation mistakes that can be easily avoided. We recommend consulting with a professional before beginning installation. Polygal can offer years of use and enjoyment with the right installation techniques.
*TIP* The protective film should be removed as soon as installation is completed. Prolonged exposure to the elements will cause the film to be next to impossible to remove.
Moisture and Debris in the Flutes
Leakage is the #1 issue that customers contact us about. There are several mistakes that cause leakage to occur, but they are all easy to prevent.
- Your roof should have a minimum slope of 10% to keep water moving in the right direction.
- Do not have any seams running horizontally or perpendicular to the slope. For this reason, we offer 24 foot long sheets of Polygal.
- Make sure to pre-drill holes larger then the screws themselves and use a sealant. This allows for expansion and contraction from the weather.
