Window Replacement Systems – Kalwall
Retrofits with Kalwall vs. Glass results in dramatic savings for stopping heat loss, reducing electric light usage by offering glare free-usable diffuse daylight, eliminating the need for shades, and decreasing solar heat gain. Our high performance systems are very competitively priced, virtually maintenance free, and offer increased security compared to typical glass retrofits, for both increased impact resistance and vandalism.
Technical Information
Savings from retrofitting with Kalwall -the most highly insulated light transmitting fenestration system on the market, can exceed 400% vs. standard glazing systems.
Before Window Replacement
Old, drafty single-pane glazing produced excessive glare and inhibited learning.
After Window Replacement
Energy-efficient Kalwall system creates a comfortable and protective classroom
