Testimonial from a certified installer

“I have been a door and window installer for over 15 years. I have worked for different manufacturers and distributors, and I’ve noticed that doors and windows are constantly changing. There are so many products and assembly options available. As a professional, I have a responsibility to understand, master and apply the Canadian installation standard and manufacturer’s recommendations. With Isothermic, we get training tailored to our work as door and window installers. I think it’s great that a company is finally taking installation seriously. The installation program developed by the Isothermic team is really comprehensive. They’ve thought of everything from A to Z. I’m happy to be an Isothermic certified installer.”– Charles L.
