Eliminate mold on the window rumpfinger windows blog

Mold on the window and window seals occurs very often. Responsible in most cases is a bad insulation, a wrong ventilation behavior and/or humidity damages, whereby the thermal bridges develop and the areas cool down strongly. You can recognize the mold infestation by unsightly, dark spots, which in the long run can affect the building structure and endanger health. In the following article you will learn where the mold comes from and what you can do about it.

Fungal spores love all organic materials

Molds are microorganisms, which to the growth

– nutrient-rich soil – moisture – heat

need. Suitable breeding grounds are z. B. wood, plastics, rubber, wall plaster and paints. In the window area they settle mostly in bathrooms. In the kitchen as well as on window joints. The infested areas
discolor and form mildew stains: at first they are small and punctiform, then they become larger and circular, and in the final phase they grow into a fungal lawn.

Causes of window mold

Especially in winter, when you heat a lot in the apartment and the windows remain closed most of the time, a lot of moisture is formed by showering or cooking, which then condenses on the cold window pane. This leads to the fact that the spores are predominantly

– on the window frame – on the window sill – on seals

come to light. Also heavy curtains favor the emergence from mold: the areas behind the curtains are much cooler than the rest of the room. Condensation develops in these places. Deposits on the neighboring surfaces.

Uninsulated roller shutter boxes are an optimal shelter for the mold in the apartment. The air in the shutter box is extremely cold. Presses on the inner wall of the apartment. In the interior wall, warm air and cold partial surface meet and condense at lightning speed, because the temperature differences are very high. This happens more often in old buildings, where the shutters are poorly insulated or not insulated at all.

special case: roof windows

Roof windows are particularly exposed to weather conditions such as snow, hail, rain or storms compared to vertical windows. Since they cool down more than normal windows, you should be ventilated as soon as possible after the condensate has precipitated – otherwise the window will mold over time. As a remedial measure you can

– moldy window seal – the affected sash – the old skylight pane – the whole skylight window

Home remedies for the removal of mold

Mildew spots on the window glass can be washed off with a cloth and a commercial cleaner. Disinfect the areas for complete mold removal with high percentage alcohol. The mold on the window frame can also be removed with a cloth soaked in alcohol, provided that it is only superficially on the window frame.

How difficult or easy you eliminate the mold on the window depends on the material of the window frame. With washing-up liquid and microfiber cloth you can remove the dirt on the window seal without damaging the sensitive silicone layer. Cleaning milk and scouring milk are suitable for foxing stains on silicone grout that has not yet been properly absorbed; however, you will need to repeat this curtain from time to time.

You can also remove mold spores from a silicone joint with vinegar cleaner or pure vinegar remove. When using pure vinegar, remember to always use it only with gloves, because it has a corrosive effect. Methylated spirits and hydrogen peroxide help kill fungal spores for good. But you dry out the window joints, which later makes the seal porous.

If you have already treated the stains with another home remedy, but they are still visible, then try Baking soda and grout from. However, this method only remedies the problem if the window joints are white. There are other mold removers on the market like:

– Chlorine cleaner – Mildew spray with sodium hypochlorite – Mildew remover with special fungicides (fungus killers).

Prevent mold with proper ventilation

Prevention is better than cure. Even in the case of mold, you can achieve much more with preventive measures. Mold prevention most important. Frequent. Vigorous ventilation is much better than the well-intentioned continuous ventilation with tilted windows. Frequent and vigorous airing is much better than the well-intentioned continuous airing with tilted windows. Continuous ventilation has the effect that the walls cool down too much.

When you ventilate intermittently, you ensure that the air in the room is completely exchanged without the walls becoming excessively cold in the process. If you don't have the time or the inclination for manual ventilation, then a controlled residential ventilation a solution. The use of a ventilation system should be taken into account from the very beginning when planning the construction of a house.
