Condensation
Ever wonder why your windows fog up in the winter? It’s because
the hot air inside your home clings to your cold windows, leaving
behind water vapor. In the winter, the cold air outside makes even
the inside of your windows cold to the touch. But Castle Window
Covers insulate the warm air from the cold glass, virtually eliminating
any chance of condensation on your windows, all while keeping the
temperature inside your home comfortable all year long.
