PES is very popular in the Great Lakes, the Rocky Mountains and the Northeast regions where extreme cold and heavy wind are often a concern. Our curtains are built to withstand extreme cold and wind. Even our clear vinyl has been laboratory tested for Low Temperature Flexibility @ -30 F with no cracking, and Dimensional Stability (shrinkage & expansion due to temperature change) of less than 0.5% (1/2%).  Most products see significant cracking at these temperatures and shrinkage and expansion of 5-7% is common. These changes can significantly alter the look of your enclosure, the ability to fasten it in cold weather, and your enclosures longevity.  While our enclosures are made to withstand extreme cold, we still recommend keeping your enclosure down when temperatures are below 55 degrees Fahrenheit and only rolling up the fabric portion of your enclosure if you still like the airflow. This will assure you can use your enclosure with minimal effort and provide many years of use for your PES enclosure. 

All of our components have been tested in extreme cold and our manufacturing process comes directly from many years of experience in the sailmaking industry.
