Pergolas

Our “Cover Your Pergola” systems are our unique solution to cover outdoor patios, pergolas, and awnings.

SkyPoly Multiwall Polycarbonate sheets often referred to by the brand name of Polygal or Topgal, are a structured sheet product available in double and triple layered configurations and manufactured in various colors and degrees of transparency.

SkyPoly allows sunlight in but provides protection from unwanted elements, such as rain, UV rays, and heat. What this means for you is that you can comfortably enjoy your patio rain or shine with a SkyPoly roof cover! SkyPoly roof panels for pergolas are durable, yet flexible, so they can be utilized in curved applications. Plus, SkyPoly is lightweight and easy to install so you don’t have to break your back or the bank to enjoy your clear plastic patio cover.


When a customer purchases any of our Cover your Pergola systems, they are getting everything they need to install the material and the support of our architectural specialists and sales team. We offer installation videos, instructions, and a list of contractors that have experience installing the material.

Pergola FAQs

To clean dirt and debris on the outside of the sheets, the easiest method is to simply spray the sheets off with water. You can also rinse with a mild soap, like Ivory, and then follow that with a clean water rinse. If you want to try hand washing, proceed with caution as Polygal can be scratched easily.

To clean dirt and debris from inside the flutes, first, remove the U-profiles and tape on the edge of the sheets. Use a vacuum to remove the dirt. Using an air compressor or blower can push dirt and debris further into the flutes.

Polygal can be easily cut with a circular saw, table saw, or a contractor grade jig saw on site. A carbide bit fine tooth blades with 8-12 teeth per inch is recommended. Cutting the material can lead to plastic shavings in the flutes. You can use a vacuum or an air compressor and blower to remove the shavings.

Polygal multiwall polycarbonate can be considered a roof for pergolas. The standing seam system, Topgal, is a leakproof roof, even on pergolas that are flat or have minimal slope. There is also a plastic base and cape system and an aluminum megalock system that offer an effective shade cover. These systems are not considered a “roof” just because they are not guaranteed to be leak proof on flat pergolas, but with the appropriate slope and correct install, these products are also virtually leak proof.

Polygal multiwall polycarbonate sheets do not allow for any flame spread. The sheets may melt, but they will not catch fire. The standard 8mm panels have a Type I or CC1 flame rating.

Polygal sheets are available in standard width options of 4’ or 8’ and in standard lengths of 8’, 12’, 16’, or 24’. Custom lengths are available as it is important to have a seamless sheet in the direction of the slope so the cover does not leak.

Polygal sheets should not be welded together with adhesives. The sheets are available with different seam profiles to connect the sheets.
