Windows have important role in regulating heat and energy consumption. Old windows are generally
drafty, but new windows also have a disadvantage of giving away and receiving a lot of heat through
the glass surface.
From 30 to 50% of the average household costs are redundant because of unnecessary loss of
heat
through untreated windows. During the summer period, sun blasts throug windows make the
inside of
the room too hot, so that intensive air conditioning is a must. In the winter, heat loss through
windows burdens the heating system. Both cases result in higher costs.
One of the most affordable ways to improve the energy efficiency of the windows is the
installation
of thermal insulation films. They represent a simple and very efficient way to protect
the interior
from excessive heating during the summer, or heat loss during the winter. In this way, with the use
of protective window films, energy consumption can be significantly reduced.
LLumar window films block up to 85% of total solar heating during the summer, while
preventing up to
55% of heat losses. In this way, window films enable energy consumption throughout the
year, cutting
heating and cooling costs.
