Effective Window Insulation Tricks to Drastically Lower Energy Bills

Installing Thermal Insulation Film

This insulation film is easy to install and made from a thin plastic that effectively retains heat indoors, thus reducing heating costs. It’s especially useful for single-glazed windows. Before installation, clean the windows as you’ll need double-sided tape to ensure the plastic film adheres well. Typically, the tape comes with the insulation film. Apply the tape around the window frame and cut the film to fit the windows. Use a hairdryer to apply the film smoothly and avoid wrinkles.
