Glass and Window Film Compatibility | Technical Information Guide

Thermal Stress Disclaimer:

Before applying window film it is important to ensure that the film you have chosen is suitable for your type of glass. This chart details which film is suitable for which type of glass.

The Window Film Company UK Ltd cannot be held responsible for problems that arise from applying an incompatible film, or from applying window film to a glass with an existing defect.

If you are in any doubt, please contact one of our experts on 01494 794477 who will be able to advise.

In all cases, your glazing should meet the Code of Practice BS6262 Pts 1-7 and BS8000 Glazing Workmanship on site. Damaged edges and other hidden defects can be highlighted by the application of window film and in a small number of cases this will manifest itself in a crack, emanating from the damaged area.

Neither the manufacturer nor The Window Film Company UK Ltd can assume responsibility for this type of breakage. It’s important to understand thermal cracking but equally vital to be assured that with the correct film choice, it is highly unlikely to affect your glass.

Other factors that may result in thermal stress include:

i) If your glazing is subject to partial shading.
ii) You have tightly fitted blinds or curtains.
iii) There are heating or cooling vents pointing directly onto your glass.

The Window Film Company cannot be held responsible for any damage that occurs as a result of installation in these circumstances, so if you are in any doubt as to the suitability of window film for your windows, please contact us directly on 01494 794477.

Please also pay attention to the following information.

If any of the below apply to your glazing system, please contact us for an advice or suitable film suggestion on 01494 794477.

1) Film may not be suitable if your pane is larger than 3m2 or is longer than 4.5m on any side. If you are intending to film glass of this size, please contact us to confirm suitability. The same applies if your glass isn’t toughened and is thicker than 10mm.
2) Film may not be appropriate if your glass is reflective or already has a tint.
3) Under no circumstances should you fit window film to glass that is already visibly damaged.
4) If your window is triple glazed, please avoid fitting window film..
5) Unless using Frostbrite frosted film, do not part film windows. The resultant differing absorption rates could place the glass under additional pressure.
