Thermal Sash Window and Door Systems Inc
“We just replaced 24 windows in our house. Working with Rob O'Connor was an absolute joy. We had priced out windows from all the major manufacturers and distributors and by far Thermal Sash was the most competitive. Take it one step further, their product, Okna Windows, after exhaustive research also turn out to be on the high end of quality as well. The installation was a breeze and far exceeded my expectations of quality work. Thermal Sash came as a referral from a neighbor, and I would absolutely refer them to anyone else.”
