Tips for caring for window and door seals.

Maintaining window seals increases the service life many times over

In order to guarantee the permanent tightness and insulating effect of window seals, the associated care is very important. This increases the service life and functionality of the window seals by a factor of three to four.

Basically, care begins with keeping the surfaces of the seals dry. Care should be taken to ensure that the rubbers are not moistened by condensation or rainwater. This is particularly important during the heating period. If necessary, the seals should be wiped dry with a cloth, as this also reduces the risk of possible mould growth.

To support the elasticity and function of the rubber, the surfaces should be treated with a grease or talcum stick or silicone spray. This is particularly important in the winter season. In summer, a talcum powder can be used to bind moisture and prevent the window seals from sticking to the window frame.

Maintaining your window seal keeps it supple and prevents it from sticking to the window frame in summer and freezing in winter. Gasket care is an important part of maintaining the function of your window gasket.

Ventilation instructions
In order to save energy, the building envelopes of houses and flats are becoming increasingly tight. This "tight" construction prevents sufficient natural air exchange. It is therefore necessary to open the windows 2 to 3 times a day to let fresh air into the room and allow moist, stale air to escape to the outside. Cross ventilation is ideal for this. To do this, open the window sashes on at least 2 opposite windows. After 3-5 minutes, sufficient air exchange has taken place and you can close the windows again. Never leave the windows permanently in the tilt position during the cold season. This would allow large amounts of expensive heat energy to escape and the window reveal would cool down so much that there is a risk of mould forming. We recommend using a digital thermometer/hygrometer to check this. This shows how high the temperature and humidity are in the rooms. Ideally, this should be 20 to 22°C and 50% relative humidity.

Another tip: Reducing the room temperature by 1°C can save up to 6% on energy costs.
