How can you prevent condensation on windows?

Insufficient ventilation oversaturates the air with moisture, causing condensation. Relative humidity determines how much moisture air can retain; condensation forms when saturation is reached.

The most common moisture sources are:

• Showering, cooking, ironing and drying laundry
• Large numbers of houseplants
• Insufficiently heated rooms
• Several people present (breathing releases water vapour – a family can produce over 10 litres of vapour daily)

To prevent condensation, ventilate rooms several times daily, especially kitchens and bathrooms. Open windows fully rather than leaving them tilted, as prolonged tilt ventilation can increase heating costs without significantly reducing humidity.

If your windows are worn out, consider energy-efficient replacements with double or triple low-e glazing. Old windows can allow moisture in and worsen condensation.

By installing SAPLAST windows and doors, your home will retain optimal temperatures and reduce heating costs. Because PVC windows seal very well, proper ventilation is crucial for preventing condensation. We also recommend RAL installation, which ensures a quality window-to-wall connection, further reducing condensation risk.

Warmer air holds more moisture, so maintaining constant room temperatures is important for reducing condensation. Place radiators and other heaters beneath windows to form a thermal barrier and reduce temperature differences between indoors and outdoors.

Quality windows and doors, proper ventilation and humidity control are crucial for a comfortable, healthy home. SAPLAST provides optimal thermal insulation and energy savings, with advice on correct use to avoid condensation problems.
