Tips for caring for window and door seals

Tips for optimum rubber care of window seals

First of all, a reference to our YouTube video on the care of window seals.

Caring for window seals

Maintaining and cleaning seals regularly increases their service life many times over.

Before you choose a new seal for your windows and doors, it is important to check the condition of the current seal. If it is hard and brittle, a new seal is needed. It is also advisable to check the seal regularly for cracks or damage and repair or replace it if necessary. An intact seal not only ensures better energy efficiency, but also greater safety and comfort in your home.

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

Gasket care - Do gaskets need to be cared for?

Yes, gaskets need to be maintained. Simple cleaning can be carried out with rinsing water, whereby harsh cleaning agents or oil should be avoided. Basically, care begins with keeping the surfaces of the gaskets permanently 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 clean cloth, as this also reduces the risk of possible mold growth.

Which care product for window seals?

To support the elasticity and function of the seals, the surfaces should be treated with a grease or talcum powder or silicone spray. Special care products for seals can be found here. It is advisable to treat the surfaces of window seals regularly to extend their service life and ensure a better seal. Grease is good for rubber seals as it keeps them supple and protects them from drying out. Talc can be used on older or porous seals to improve their performance. Silicone spray is particularly suitable for window and door rubbers as it is water-repellent and facilitates the movement of the seals. It is advisable to treat the seals every few months to maintain their functionality.

Are there any special care recommendations for the winter and summer seasons?

Care is absolutely essential, especially in the winter season, as this prevents the window seal from freezing to the window frame. Gasket care is an important part of keeping your window gasket in good working order. In summer, a talcum powder can be used to bind moisture and prevent the window seals from sticking to the window frame. .

Furthermore, minor damage can be detected and repaired at an early stage before major problems arise. This can prevent costly repairs or even the need to replace the entire window. A well-maintained window seal also improves sound insulation and contributes to a pleasant indoor climate. It is therefore advisable to clean, check and, if necessary, replace the window seals regularly in order to maintain the efficiency of the windows.

How do I ventilate properly?

In order to save energy, the building shells of houses and apartments are becoming increasingly airtight. 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 thermal energy to escape and the window reveal would cool down so much that there is a risk of mold growth. 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.
