STOP! Thermolite windows install on the interior to reduce the noise infiltration, provide a security barrier and increase energy efficiency of existing windows. Thermolite Window System offer a lower investment and faster returns than traditional windows. We also have financing available. Minimize disruptive window projects by installing from the inside of the building and transform your existing glass system into a high efficiency window.

Since Thermolite Window Systems install on the inside of building, your building's historic integrity is maintained and the exterior glass facade is integrated into our system.

Industries Report

The Thermolite Window System is the perfect solution to energy security for military installations; we possess both GSA and DOD bomb blast requirements. Our system is utilized for security solutions of susceptible buildings as well as for energy solutions in both administrative and housing facilities.

Thermal Imaging Report

One of the best ways to estimate the expected savings from using our system is for us to install a "mock-up" next to an existing window and take a thermal image showing the difference. By calculating the temperature gradient and combining it with some basic building information, engineers can evaluate the cost benefits of using the Thermolite Window System.

Energy Modeling Report

We use the latest window design software WINDOWS 6.3 developed in concert between the Department of Energy and Lawrence Berkeley National Laboratories. This enables us to configure your existing glass with our system to produce the desired R Value, U Value, Solar Heat Gain and Visible Light transmittance.
