What is an interior supplemental window system?

The Therm-O-Lite product line is engineered and designed for existing facilities both commercial and government. Our window system is installed from the interior of the facility and supplements the existing prime window. All of our systems have been designed to provide energy savings, and noise reduction. Our Safety Series 2000 product has incorporated a technology which provides blast resistancy. And, our systems are a fraction of the cost of a prime window replacement.

Overall our value is an effective low cost solution to issues of blast resistancy, energy savings, historical preservation and noise reduction.
