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.
