Glass Film FAQs
Film applied to glass according to manufacturer's specifications can never be the sole cause of thermal breakage. Only if the glass is not manufactured and/or installed to established industry standards can window film be a contributing factor. To reinforce this point, some window film solution providers even offer a five-year thermal breakage warranty that includes glass and film replacement.
Most higher quality window films are protected by ultraviolet inhibitors, guaranteeing that the films will not discolour over time. 10-year manufacturer's material and labour warranties usually back up these claims.
The higher quality polyester window films offer an abrasive coating and adhesion technology that ensures that the specific requirements related to performance and appearance can be met over the long term (20 years or more). After this time, the film can easily be removed and replaced with a new film. The 3M films are compatible with standard ammonia-based cleaning solutions and procedures.
Some of the newer products, such as 3M Night Vision Films, not only offer the required solar protection but also allow clearer viewing from the inside at night.
Glass breaks when stressed. There are five types of stress that may cause glass breakage:
- Thermal Stress - from absorption of solar radiation.
- Tensile Stress - from the weight of the glass itself.
- Mechanical Flexing Stress - from wind.
- Impact Stress - from flying objects, (hail, baseballs).
- Twisting Stress - from building or window frame sagging or settling.
The first type, thermal stress, is the only one which film may affect. The use of window films will increase the thermal stress on sunlit glass. However, there are also other factors which will increase thermal stress such as: partial shading of windows from overhangs, tightly fitting drapes or blinds, signs or decals on windows, heating and cooling vents directed at glass. In addition, different types of glass (annealed versus tempered, clear versus tinted) have different solar absorption rates and will withstand different degrees of thermal stress.
