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 proplast, 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 proplast– as you can see from the red and yellow areas. After replacing the windows, heat losses are kept to a minimum.

Protect the environment and your bank balance with outstanding energy efficiency.

Reduce your home's energy consumption with proplast windows  - a noticeable financial relief for you and an important step towards ecological responsibility.

Whether you're building from scratch or renovating your existing property: With an incredible heat insulation coefficient of just 0.60 W/m²K, the energeto® is the best window in its class. It already exceeds many of the requirements of the German Energy Saving Regulation, which is not set to be introduced until 2020!

Saving up to €2,500 in heating energy costs, energeto® is a sound and solid investment that pays off twice: It maintains the value of your property in the long run and saves real money. Taking into account the initial costs, energeto generates solid and secure returns that conventional financial investments usually cannot achieve.

Both you and the environment will benefit from the enormous reduction of your home's energy consumption: The CO₂ emissions of your property will be reduced by up to 7,300 kg each year.

proplast windows are up to 20% lighter and yet even more stable than conventional windows. This saves fuel during transport and protects the environment.

And you? You will soon come to appreciate the higher standard of living you enjoy as a result of well-insulated windows.
