Since 1979, Thermolite has been a leading innovator in supplemental interior window systems. Thermolite is a GSA-certified contractor and works with governmental agencies, the U.S. military, commercial renovators, hospitality facilities, and historical preservation projects.
The product cornerstone revolves around ENERGY and is represented by the colors of our square logo as SAVINGS, EFFICIENCY, INTEGRITY AND SECURITY.
The patented Thermolite Window System is a one-of-a-kind alternative to traditional replacement windows. This 100 percent customized window system is designed to provide superior protection against bomb blast, radio frequency intrusion, and hurricanes while reducing noise, sealing the building envelope and preserving historic architectural integrity.
The system is installed quickly, from the building interior using a process that provides discreet and non-intrusive installation. Many systems can be installed during evening or off-peak hours for your convenience and security.

** NOTE TO SPECIFIER ** RetroWAL 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 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 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 cu ft per min per sq ft (3.014 and 12.056 L per min per sq m) 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.
RetroWAL can provide acoustic, security and cyber resistant solutions, depending on the selected glass.
