Reduce your heating costs

Save energy with thermal insulation

Are your heating costs too high? Normally, this is in fact down to your windows, not your heating system.

"They'll do for a few more years." That's what most home owners think when looking at their old windows. However, just because your windows still look ok from the outside does not necessarily mean that they offer anywhere near enough heat insulation. Very few people are aware of how much money they are literally throwing out the window on account of poorly insulated windows. Putting the replacement of old windows on the back-burner definitely won't pay off in the long run.
With energy-saving windows by aluplast, you not only save money, you also do your bit for the environment, too.

While just 8 % of a building's outer shell is made up of windows, they are the source of almost 40% of heat losses.


The thermal imaging camera shows one thing for certain: High surface temperatures and, as a result, significant heat losses are visible in the area around the glass and frame before the renovation with aluplast – as you can see from the red and yellow areas. After replacing the windows, heat losses are kept to a minimum.
