Our solar heat control films are ideal for your home, business premises or retail outlets, and can be applied directly on any smooth glass surface. Window film is truly revolutionary as it enhances your comfort for a fraction of the cost of curtains and blinds, whilst still allowing you to see out. Window films are self adhesive or static cling products which are easy to retro fit to your windows and doors, or on a conservatory. The effect is immediate and you should notice a temperature difference especially on hot summer days.

Another benefit of these solar films is that they also stop up to 99% of UV rays, which in great part cause fading of furnishings, carpets and wooden floors.

Window Film Composition

Most solar control tints are made of layers of different materials and fine metal particles, which are bonded together. This is what makes residential and commercial films different to car tints, as car tints are usually just single layered dyed films. These films act in a spectrally selective way, mainly by targeting short wave infrared (SWIR) components of the light spectrum, preventing the heat gain cycle from taking place, and therefore making your room cooler.

Too much glare

If excess glare is also an issue, and you struggle to watch your television or computer screen, you might want to consider a tinted or heat reflective window film which will also reduce the amount of natural light to enhance your comfort. Glare reduction can only be achieved by making the glass darker and shielding the sun rays, just like sunglasses or car tints would do. Most of our solar films come in 3 grades from dark to light, so you can mitigate the loss of light to suit your requirements.

Double glazed units

When applying heat reducing film on double glazed units, there are a few considerations. Firstly, the darker film can only be applied if the internal pane of the unit is made of toughened glass, so please make sure you check the kite mark on the glass and the film's specifications first. Double glazed units can act as large radiators trapping the heat within the panes. Therefore the most efficient heat control films are the external grade ones as they stop the heat building up within the panes and therefore getting trapped in the room.

Shops and retail outlets

If excess heat is an issue in your shop or store, and you don't want to compromise the view through the window, our HRF-40 heat rejection film has a very slight colour hardly noticeable once on the glass. This window film is very popular with large stores, and especially food stores. It also reduces UV light by 99% helping prevent your displays from fading.
