The impact of the Window Films on Energy Efficiency

Watch the video of the European Window Film Association (EWFA) about the impact of window films on energy efficiency.
Building sector accounts for as much as 41% of total energy consumption in Europe, which is more than transport (32%) and industrial consumption (accounting for only 25% of total energy consumption in Europe).

Windows have very important role in regulating energy consumption in the building sector, and 75% of windows approximately are not energy efficient. For the enhancement of the window energy efficiency (for new as well as for old windows) EWFA recommends thermal insulation films.

Window films significantly increase energy efficiency of the buildings. These foils provide a much better thermal insulation, which can reduce heating and coolling costs up to 30%. 

During the summer period, on third of the load on the cooling system is the solar energy that passes through the windows. In such conditions the films block solar heating from the exterior side of the glass, which significantly reduces the room temperature as well as the cooling costs. In addition to that, the window films reduce the glare and block up to 99.9% of the UV rays which protects from negative radiation effects and prevents the furnitre paint bleeding.

Quality window foils act as thermal insulation, and during the winter period they prevent heat loss and thus reduce heating costs.

LLumar window films during hot summer days block up to 85% of total solar heating, while during the winter they retain up to 55% of heat losses that pass through the window. In this way, Llumar window foils provide energy savings throughout the year.
