How to Fight Condensation
How does condensation work?
Two things are needed for condensation to form - moist air and cold surface. Anything that emits water vaporation such as cooking, laundry, ironing, flowers, and even people in the room, increases the humidity in the room. When moist air reaches cold surfaces such as window frames, window glass, or exterior walls, moisture condenses on them.
Why after replacement of the old wooden joinery with PVC, condensation, and mould appear?
The old windows do not seal well, and as a result of which there is constant unwanted ventilation, in which the humid air leaves the room, but along valuable heat is lost. Unlike wooden windows, the new PVC windows provide a seal that does not allow moist air to leave the room. As a result, the humidity rises and condensation appears on the coldest surfaces - most often walls and windows.
In new buildings, the humidity is increased due to the evaporation of moisture accumulated in the building materials, and this process lasts about a year.
How to solve the problem of condensation?
To prevent condensation and mould, we must eliminate the factors that cause them: high humidity and cold surfaces.
Here are some easy ways to successfully fight with condensation by eliminating high humidity:
Ventilate the premises:
Ventilate the premises for 5 minutes, several times a day. This will not only reduce the humidity but also refresh it. If you ventilate with the window wide open, by creating a draft for a short time, the temperature will recover very quickly, so do not worry about heat loss in the room - the heat accumulated in the air is significantly less than that accumulated in furniture, objects and walls. Avoid keeping the window slightly ajar for a long time, prolonged entry of cold air will cool the walls and furniture and then the temperature will recover more slowly and, accordingly, with greater energy consumption;
Do not ventilate wet rooms with open doors:
Bathrooms and laundry rooms are often ventilated by opening their doors. This increases the humidity and leads to condensation. Instead, use fans mounted to the ventilation shaft;
Avoid drying clothes indoors
When cooking, use an extractor hood to remove steam
Move the flowers and anything else that might increase humidity outside the rooms with condensation
