Solar Gard window film reflects significant solar energy, while absorbing another portion of the energy. The result is that the amount of solar radiation transmitted inside the room is considerably less. Specs will vary depending on the Solar Gard window film selected.
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. During peak summer times in the middle of the day, loads on air conditioning systems can be reduced enough to turn off entire units or to install a less costly system.
In addition to the energy saving benefits, solar window film can increase thermal comfort, reduce glare, while at the same time rejecting 99% of the UV radiation reducing fading and the risk of skin cancer.
