Insulation foil for old & simple glass windows. A heat insulating air-cushion is formed & it also offers similar insulation to additional glass-panes Prevents cold, saves power, clearly reduces condensed water formation on panes. After the insulating film is applied to the window, the film is heated with a standard household hairdryer & shrinks into place, forming a transparent coating with no wrinkles or buckling.
