At Thermal Windows, we're proud of the quality of our products, installation and service. If a problem occurs that is covered by our warranty, you have the comfort of knowing that you will be dealing directly with us, the manufacturer who is familiar with you and your order, not a factory in a distant state. Since proper installation is a crucial part of window and door performance, our Lifetime Warranty only applies to products installed by Thermal Windows.
