Plastic windows for the cellar - advantages and designs


In many cellars there are still very simple and inexpensive steel windows. However, plastic windows offer significant advantages in this area. Which these are, which price differences exist, and which versions of plastic windows there are, read here.

Comparison with steel cellar windows

In unheated cellars you can often find basement windows made of steel, because they are much cheaper than plastic windows.

Since the basement is unheated, a thermal insulation plays in the basement window in this case, no important role. Some steel cellar windows are even extra designed so that the best possible aeration of the basement premises is created.

However, this ventilation can cool the insulated basement ceiling, thus reducing the effect of the insulation. This is especially true when a permanent train is created in the basement through the steel cellar windows.

If, on the other hand, tight plastic basement windows are installed, this cold air flow is largely excluded. Even with tilted plastic windows, a much lower cooling effect of the basement ceiling is created.

Price differences

The prices for basement windows are not only based on the window material, but always after the execution.

Plastic windows with pure tilt function are still relatively inexpensive, tilt-and-turn windows for the basement, which also have a thermal insulation are already significantly more expensive.

As soon as a window has nearly the quality of living space, the prices rise significantly.

Burglary protection in cellar windows

Steel windows usually have an integrated steel grid to prevent the intrusion of rodents and unwanted persons through the basement window. As a rule, this also serves as a very effective protection against burglary.

For tilting windows made of plastic or tilt-and-turn windows, however, appropriate protection must be provided. The basement windows, which are easily accessible to any burglar, should definitely be burglar-resistant.

Attaching window grilles alone is often not enough. If in doubt, you should discuss with an expert the necessary protection and the necessary protection class.

Tips & Tricks

In heated cellars used as living space, however, the same conditions apply as for the windows in the other floors. Here, it is then also on the U-value of the windows, also the size of the light area should be chosen as appropriate - usually a little more than a room on the ground floor, since generally less light penetrates.
