The right way to care for your windows

Tips on cleaning, looking after and ventilating your uPVC windows

Looking after the window frame

aluplast window profiles are made from premium, weather-resistant and easy-to-clean plastic. To clean the smooth, non-porous and hygienic surface, all you need is normal soapy water. Soiling due to dust and rain can be removed easily.
Do not use abrasives or chemicals, such as nitro diluents, benzene or similar agents, for cleaning. Please consult your window specialist if you cannot remove soiling using the method described above.

Looking after the gaskets

The gaskets on your uPVC window are made from premium, weather and ageing-resistant synthetic materials. When cleaning your windows, remove any dust and soiling from the gaskets on a regular basis.
Using special silicone oils on a regular basis is a good way to increase the elasticity and functionality of your windows' gaskets.
Please purchase cleaning agents for gaskets from your local window specialist.

Looking after window fittings

Hardware will retain its ease-of-motion and functionality through sporadic lubrication. Add a few drops of oil to moving parts and apply acid-free grease or Vaseline to the closing points. This will help to retain the functionality of your windows. If you require any further information on this subject, please contact your window specialist.

Ventilation and heating

Modern uPVC windows have such a high air impermeability and are sealed so tightly to the building structure that no natural air exchange can take place. Proper ventilation using modern windows can help to save heating costs and create a healthy room climate at the same time.
Cross ventilation through two opposite windows is especially quick and effective – one single open window sometimes is not enough. Keeping the window open for 5 minutes is sufficient to replace the indoor air. For a more thorough airing of the rooms, open the windows wide for 10 minutes.
You will achieve the best results by ventilating your home three to four times a day. However, it is important to make sure the flow of air is not obstructed in any way (by furniture, for example). Ventilate kitchens and bathrooms more frequently as moisture levels tend to increase due to cooking, bathing, taking a shower, etc. As a general rule of thumb: If your window is fogged up, then it's time to ventilate.
To facilitate ventilation, Basic Air plus® or REGEL-air® ventilation systems can be installed in the window.

Initial cleaning for uPVC windows following installation

Despite all the care taken by the craftsmen during installation, soiling like residues of mortar, wallpaper paste, adhesives etc. may occur. Residues of mortar and colour splatters can be removed with a semi-rigid putty knife by carefully scraping off the soiling. After that, wipe with a damp cloth.

Please be careful not to scratch the surfaces with the small but sharp pebbles in the mortar. Residual adhesives on the glass surface can be removed carefully with an inclined razor blade.
