Insulating film for windows consists of a transparent plastic film that is fixed to the window frame from the inside using double-sided adhesive tape, creating an insulating layer of air between the windowpane and the foil.
After the insulating film is applied to the window, the film is heated with a standard household hairdryer and shrinks into place, forming a transparent coating with no wrinkles or buckling.
