This is the Extra Strong version of the window film which is twice as thick as the standard film.
The film shrinks when heated with a hairdryer, creating a tight seal that prevents cold air from entering and warm air from escaping. The film is transparent and does not reduce the amount of light or visibility through the window.
- Keeps out draughts and helps stop condensation
- For use on painted / varnished wooden / Aluminium / PVC / uPVC / Vinyl windows frames
- Does not reduce the level of light coming through the window
