Window film is a self-adhesive polyester based film that is applied to the interior surface of flat glass. It is generally designed to reduce heat energy particularly to upgrade control of solar heat energy, reject UV radiation, as well as giving a building a certain type of aesthetic image. There are two types of window film – non-reflective or dyed films that primarily absorb solar energy, and reflective or metallized films that absorb as well as reflect solar energy.
Insulated glass unit that has a low-e coating on the #2 surface designed to provide some heat rejection in the summer and heat retention in the winter. While a good investment and now required in all residential construction since 2003, the typical builder grade low-e glass provides for approximately ½ of typical heat rejection of solar control window films and does not address UV or glare reduction.
Same as window film – the tint refers to how much visible light is being transmitted- the darker the “tint” the lower the light transmission.
Screens applied to the exterior of windows. Designed to filter the visible light to reduce heat.
Reference to the replacement of the entire frame and glass.
Reference to the replacement of the glass portion only of existing window
Refers to attempting to repair and broken seal in a insulated glass unit without replacing the glass- very mixed results only work in certain situations.
AKA – the overall heat transfer co-efficient. The measurement of heat loss through a material, such as a floor or roof or even a wall. The lower the U-value number, the slower the rate of heat loss, which reflects a better insulating quality.
The amount of solar radiation absorbed into a home through a window/skylight. SHGC rating is used to quantify the energy efficiency of windows.
The VLT is the total visible light which passes through a window/window film. It is measured by percentage. The film gets darker the lower the percentage. (i.e. 90% VLT window film is virtually clear, while a 10% VTL is quite dark.) Depending on the manufacturer, the darker the film, the more heat is rejected. All solar window film blocks 99% UV rays.
The amount of sunshine that is visibly reflected by a window; the more the reflective or mirrored appearance, the higher the value.
The amount of ultraviolet radiation blocked from passing through your window. These wavelengths are the primary reasons behind skin damage, fading, and discoloration. Solar window film block 99% of UV rays, which will protect your family from damaging UV rays, fading furniture and flooring.
The amount of solar infrared radiation, (IR) that is blocked from passing through the window film. IR is most commonly known as “heat radiation”. IR light from the sun accounts for 49% of the energy that heats the earth.
