With the TesaMoll Thermo Cover insulating foil transparent from Tesa you can easily insulate windows in your home. The non-adhesive film acts as an insulating air cushion. This makes it ideal for windows where a second layer of glass is missing. The window insulation also reduces the condensation of windows. You simply attach the insulation foil to your window with the supplied transparent double-sided adhesive tape. Use a hair dryer to smooth the foil. The TesaMoll insulation foil measures 4m x 1.5m (6m²).
