Our curtains are built to withstand extreme cold, heat, and weather. The clear vinyl will shrink and expand slightly with temperature changes. The change is less than 0.5% (1/2%), far less than the standard 5-7% of most clear vinyl enclosures. Any changes in size can make fastening (closing) your enclosure in colder temperatures more challenging.  We recommend keeping your enclosure down when temperatures are below 60 degrees Fahrenheit and only rolling them up to the bottom of the clear vinyl if you still like the airflow. This will assure you can use your enclosure with minimal effort. 

Our manufacturing process comes directly from many years of experience in the sailmaking industry. All of our components have been tested in extreme cold, wind (pressure), abrasion, heat and sun (UV).
