Each of our products go through rigorous testing on-site and in-lab. Our service lab is located in Calgary, Alberta, Canada. What better place then this could we use as our home-base? We have some of the most extreme temperature variations in the world. It can go from -20 degrees Centigrade to + 20 degrees in a matter of 8 hours. This temperature swing is very hard on most products in construction, but with WeatherSkin, our products are made to beat out the cold and perform just as well at -40C as they do at + 40C. We have put the products through rigorous testing to ensure premium performance. Everything at WeatherSkin is engineered to the highest standards.
