Tinted Windows Save Energy
Simply Blinds is now installing Tinted Window Film to the inside of glass conservatories and other large glass surfaces to reduce the amount of solar radiation that is transmitted through the glass and reduce the amount of heat that is transferred to provide cooler inside temperatures during hot sunny weather.
In ¼” (3mm) annealed glass, 87% of the energy is transmitted, 5% is absorbed and 8% is reflected.
Tinted window film reflects significant solar energy, whilst absorbing another portion of the energy. The result is that the amount of solar radiation transmitted inside the room is considerably less. The movement or transfer of heat from a region of higher temperature to one of cooler temperature is called heat transfer. The transfer of heat always flows from hot to cold. No heat will transfer if there is no difference in temperature. With solar window film installed on the inside of a window, the proportions are changed dramatically, with reflected energy and absorption increasing. This corresponds to a reduction in solar heat transmitted inside the room.
Lowering the temperature saves energy
Only a few degrees in temperature reduction can have up to a 25% reduction in cooling costs, due to the laws of thermodynamics. It requires considerable amounts of energy to remove heat from a room through air conditioning. In addition to the energy saving benefits, solar window film can increase thermal comfort, reduce glare, whilst at the same time rejecting 99% of the UV radiation reducing fading and the risk of skin cancer.
