Oklahoma Owned and Operated
Founded by Bob G. Pool in 1979, Thermal Windows has been custom manufacturing energy efficient windows and sliding glass doors in Tulsa, Oklahoma for over 40 years.
Custom Manufactured for You
None of our windows are mass-produced. We manufacture them in our Tulsa, Oklahoma production facility to your exact specifications.
Convenience
TrustGard vinyl windows are available in two colors: white and almond. Single and Double Hung sashes tilt in for easy cleaning.
Security
Double Hung windows come with special "Night" latches that allow for ventilation while preventing the window from being opened. Additional security is available with optional ThermalSafe glass.
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.
