How Window Insulation Works
Castle Window Covers are able to insulate your windows with an unnoticeable, virtually-invisible sheet of acrylic that insulates the temperature inside your home at a comfortable level all year long. GLASS vs. ACRYLIC
Without getting too scientific, a simple way to put it is as follows
Glass windows - even dual-pane windows - transmit heat through the glass, which means your glass windows are allowing heat to escape your home while you're spending money running the heater all winter long!
Acrylic window covers insulate your windows, which means that they don't allow the heat to escape through the glass windows. The heat never gets to the glass at all. The acrylic keeps the warm air inside your home, allowing it to heat up faster and stay warm longer. That means you spend a lot less in energy costs and heating bills while also maintaining a comfortable temperature in your home or office.
