Energy Saving Window Film
Energy Savings For Your Home:
Energy Savings For Your Business:
Each year, the average American household spends $1,500–2,500 on energy bills. *
45% of that cost is for heating and cooling. Windows and doors can greatly affect the cost of keeping your home or office comfortable and energy efficient. Energy saving Window film can help you save energy on your existing windows or doors… while helping with comfort.
Window Film for Energy Savings
Solar gain (also known as solar heat gain or passive solar gain ) refers to the increase in thermal energy of a space, object or structure as it absorbs solar radiation. The amount of solar gain a space experiences is a function of the total sun hitting your windows and doors and of the ability of your doors and windows to resist this solar radiation. Window film helps resist this solar radiation.
Objects struck by sunlight absorb its visible and short-wave infrared components, increase in temperature, and then re-radiate that heat at longer longer infrared wavelengths. Glass allow visible light to pass through almost unimpeded, once that light is converted to long-wave infrared radiation by materials indoors, it is unable to escape back through the window .. This trapped heat causes solar gain via a phenomenon known as the “greenhouse effect”. In buildings, excessive solar gain can lead to overheating within a space, but it can also be used as a passive heating strategy when heat is desired. In a cooling climate such as Florida this can create an undesirable situation.
Energy saving Window film affects and reduces the solar heat gain coming through your windows. Window film improves the Solar Heat Gain Coefficient (SHGC) of your windows. The SHGC is the fraction of radiation admitted through a window, both directly transmitted and absorbed and subsequently released inward. SHGC is expressed as a number between 0 and 1. The lower a window’s solar heat gain coefficient, the less solar heat it transmits.
So the lower the SHGC the better window is doing at keeping solar heat gain out.
