Since 1979, Thermolite has been a leading innovator in supplemental interior window systems. We are a GSA-certified contractor and work with governmental agencies, the U.S. military, commercial renovators, hospitality facilities and historical preservation projects.
The cornerstones of our product all revolve around ENERGY and are represented in the colors of our square logo and are SAVINGS, EFFICIENCY, INTEGRITY AND SECURITY.
Our patented Thermolite Window System is a one-of-a-kind alternative to traditional replacement windows. This 100% customized window system is designed to provide superior protection against bomb blast, audio espionage and hurricanes while reducing noise, sealing the building envelope and preserving historic architectural integrity.
The system is installed quickly, using a process that provides discreet and non-intrusive installation. In fact, many of the systems can be installed during evening or off-peak hours for your convenience and security. Contact us now to see if you qualify for a free supplemental window.

** NOTE TO SPECIFIER ** RetroWAL(TM) a Revolutionary High Performance Curtain Wall Retrofit System
Thermolite has launched a revolutionary glazing retrofit system that enables rapid ROI for the commercial energy efficiency retrofit market. RetroWAL(TM) is designed to retrofit any curtain wall or storefront application and is ideally suited for historic and landmark projects as it allows preservation of the existing facade. RetroWAL(TM) consists of a "Window Attachment Lite" or "WAL" which is easily installed on the inside of the existing glass in as little as 30 minutes and greatly minimizes disruption to building occupants or tenants. The product increases the thermal performance of single pane windows in commercial buildings, improving center of glass R-value from R-1 up to R-3 (U-factor 1 to 0.37) with the basic system. Air infiltration is reduced to between .01 and .04 cfm per square foot of window space. Solar heat gain is controlled by using between glass blinds and/or window film laminated on the opposite side of the low-e coating or the existing building glass.
The RetroWAL(TM) patent pending design places composite caps around the frame with thermal breaks reducing the conductivity of the aluminum dramatically. Typical curtain systems in older buildings have R values (resistance to heat loss) of less than R=1. This value is only the same as 1/4" Styrofoam. ThermoWAL(TM) triples the insulating value of the existing older systems, outperforms many total replacement options at a fraction of the cost. It adds minimal weight to the existing curtain wall structure which is often limits the building options.
Security variations for curtain wall structures have been implemented by Thermolite for years and are now available for the commercial building market.
Security variations for curtain wall structures have been implemented by Thermolite for years and are now available for the commercial building market:
BlastWAL(TM): Protects against blast pressures exceeding GSA and DOD standards over 12 psi.
FireWAL(TM): Protects against active shooter entry into storefront, and curtain wall lobby glass.
StormWAL(TM): Hurricanes and Super Storms cannot penetrate our glass and frame retrofit system. Designed to withstand 159 mph winds and higher 3 second gusts. Delete if not required.
