Basic Knowledges Regarding Window Film
1--Usage of Window Tint.
There are many different grades, shades, colours and thickness of available window films. Window Films are a retrofit upgrade for existing glass that can be used to address a range of problems inherent to glazing, including:
~Heat and Glare reduction
~Safety and Security
~Protection from graffiti.
Window films are an extremely cost-effective method to reduce heating and cooling costs in existing buildings by reducing the amount of heat transfer through glazing.
2--Window Film and Fading
Window films filter out over 99% UV rays to 380nm, reducing the main factor in fading. However, additional factors such as solar heat and visible light also contribute to fading. Therefore, the greatest protection from fading is offered by tinted or metallized window films that reject large levels of heat and visible light, in addition to UV.
3--About UV Window Films
The adhesive system used in window films rejects UV radiation up to 380nm. As UV is one of the main sources of fading, it can prolong the life of fixtures and fittings. Specialist UV window films are available that offer increased protection to 400 nm. These films are usually clear and are widely available. For yet further protection 500nm, tinted amber winow films are available.
