How to stop condensation on windows in winter!

T-STRIPE is a special heating system invented to heat up the outer edges of cold and wet window panes while using minimal energy (see our cost breakdown) to stop window condensation. This way both window pane and window frame will stay dry – even at very low temperatures. You can purchase T-STRIPE directly in our webshop. Assembling T-STRIPE and installation is easy, no matter what kind of windows you own. It works best on double glazed windows. And of course you do not have to install it yourself; either ask the electrician of your choice or let one of our contractors know, they will gladly help you. With T-STRIPE your windows will stay dry and top condition!


Get rid of window condensation water!

The Austrian Institute for Healthy and Ecological Building (IBO) has conducted a study on the effectiveness if T-STRIPE and confirmed that with T-STRIPE neither condensation water nor mold occured. By heating up the edges of the window pane itself T-STRIPE completely prevents condensation water and mold spores from forming and additionally causes a heat dissipation effect which increases the comfort.

T-STRIPE can be obtained at one of our many partners or directly in our webshop. We gladly direct any Inquiries regarding assembly or installation to one of our contractors or an electrician near you.

Assembly and Installation of T-STRIPE

T-STRIPE heats up the window pane in order to prevent condensation water. In connection with a Thermostat T-STRIPE requires no further manipulation, making it absolutely easy to use while conserving energy costs. T-STRIPE will only be swtiched on when needed.

Power consumption of T-STRIPE is very low, the heating element needs only 10 watts per meter. A Window with 4m in circumference will take up only 40 watts, equalling power consumption to that of a small lightbulb. To show you how low the energy consumption of T-STRIPE really is we tested its performance a whole winter in an apartment with several windows. Read up on the results here.

Condensation water can be an expensive and annoying problem. It can also turn into a serious health hazard quickly:


But how exactly does this water form on the surface of my window pane?

Condensation water occurs wherever air humidity gets too high and/or air temperature is too low.

The higher the relative humidity in the air and the lower the temperature, the more condensation occurs, and the faster this accumulation appears. Air humidity also depends on the number of people in a room, since people’s breath also contains a lot of vapour. During the colder seasons humidity outdoors is usually higher than inside. Insufficient heating and bad airflow increase the chance of condensation. That window panes are the first place where condensation happens is simply because the glass is usually the coldest spot in a room, but in extreme cases condensation also appears on walls and around entrance doors.

This is the main reason people always hear the same advice, to turn on their radiators and to air their rooms more often.

It is however very important to air and heat your rooms responsibly and economically.

During colder seasons keeping windows open constantly would be a huge mistake, since the constant influx of cold air causes the temperature in the room to drop too drastically. Reheating the room results in huge heating expenses. Instead, you should try to open up all the windows in a roomcompletely for up to 10 minutes, several times a day if needed, to facilitate a complete as possible exchange of air masses. This way it will also be easier to reheat a room. This method is also very beneficial when it comes to airing the bathroom or kitchen.

During summer constantly airing rooms is of course always a possibility.

When it comes to the temperature in a room, preferences vary. Generally speaking it should never be necessary to heat a room beyond 23°C just to avoid condensation.

If condensation occurs despite all these aforementioned precautions, then the problem has to be tackled from a different perspective. The first step should be to check the windows in question and see whether they are still properly functional. If after an expert’s inspection brings no result, then the probable cause of condensation are either bad building shells or bad airflow. Even with newer buildings condensation is oftentimes a problem, since modern architecture usually includes large windowfronts but insufficient heating sources.

There is no need for complex modifications to an existing room. T-STRIPE installation is fast and easy, no matter what kind of windows you have.
