A home or building is only insulated as well as its windows. A single pane window loses 20 times as much heat as the same area in an adjacent well insulated wall. This leads to nearly 30% of all energy used to heat and cool homes going out the window. Thinsulate™ Window Film helps improve the insulation value of a typical single-pane window close to that of a double-pane, and of a double pane close to that of a triple-pane.
