How Is The Film Different From Other Solar Control Films?

Solar control films focus on the solar energy spectrum and are primarily designed to help keep the sun’s energy from entering a building. In order to be effective, the glass needs to be exposed to sunlight. The effectiveness of a film in helping to prevent solar energy from entering a building is measured by its Solar Heat Gain Coefficient (SHGC). While Thinsulate™ Window Film has properties that allow it to reduce the solar energy entering a building, the film is also designed to help prevent the transfer of radiant heat from one side of the glass to the other. Radiant heat is based solely on the temperature difference between the outside of the glass and the inside of the glass. Therefore, the Low E properties of Thinsulate™ Window Film helps keep warm air inside during the winter months, and keep the warm air outside during summer months. Thinsulate™ Window Film helps reduce the amount of solar energy entering the building (SHGC) AND it helps provide additional insulation to reduce the transfer of radiant energy from one side of the glass to the other (U Value).
