It is very affordable, as it does not require the extra cost of glazing sheet, it allows emergency access to the window, and the film itself can be re-used once it has been carefully cut out. It is ideal for student accommodation or rented property and will ordinarily last for a complete winter. If you find that after a while the film begins to sag or wrinkle a little, this is normal, and can be addressed by repeating the careful heating of the film with a hairdryer.

Each pack contains the thermal film, suitable double sided tape and Surface Preparation Wipes, that clean and degrease the window surround before installation.
