Series 900 Casement Windows and Series 925 Awning Windows combine the views of a picture window with the ventilation and ease of cleaning found in operating windows. Low-profile hardware and narrow sight lines give them a timeless elegance.
These beautiful windows are made from strong, durable, maintenance free aluminum, featuring our special polymer Thermal Barrier.
Separating the interior and exterior surfaces, the barrier dramatically reduces heat loss in the winter and heat gain in the summer.
We make our attractive and durable casement windows in rotary crank configurations as well as push-out awning and tilt-in hopper styles. They can be made to fit nearly any opening.
Standard Features
To match your home’s individuality, we offer a wide palette of powder coating and anodized finishes.

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. Custom shapes, sizes and colors such as bronze and black are our specialty.
Convenience
Thermal windows are maintenance-free, made from strong, precision-engineered aluminum, with a durable powder coat finish that never needs painting. The tilt-in sash makes cleaning from inside your home quick and easy.
Security
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.
