Experts from Osnova provide practical advice on caring for uPVC windows. Proper care will help preserve the beauty of windows for many years.

1. Care for the PVC Profile

The profile is chemically neutral, meaning it does not react with air or moisture. The guarantee for the uPVC profile is over 40 years, ensuring that your windows won't yellow or deform during this time. However, even this undemanding material like uPVC requires some care. Clean the profile using a regular soap solution or specialized cleaners without solvents, abrasives, or acetone. Common dishwashing detergents can also be used to clean plastic windows.

2. Care for Rubber Seals

To maintain the elasticity of the seals, it's advisable to clean them from dirt once or twice a year and treat them with a silicone oil-based pencil or spray. Thoroughly wipe them with a cloth or sponge soaked in warm soapy water. The state of the seals greatly affects the thermal properties of the window, its airtightness, and noise insulation.

3. Care for Window Handles

If the window handle is loose, lift the decorative plate beneath it, turn it from a vertical to a horizontal position, and tighten the screws to rectify this issue.

4. Care for Drainage Holes

At the bottom of the frame, there are drainage channels that can be easily accessed by opening the sash. They allow water to drain from the outer surface of the window profile. If these channels get clogged with dirt and dust, moisture will accumulate, causing the windows to fog up. Periodically cleaning these holes allows moisture to drain properly.

5. Care for Hardware

The hardware of uPVC windows is subject to significant loads. Its reliability and durability depend on the quality of manufacture, materials used, assembly technique, and timely maintenance. It's recommended to lubricate all movable parts at least twice a year with acid- and resin-free oil. With such maintenance, the window hardware will remain easy to operate for a long time.

6. Care for Insulated Glass Units

Though insulated glass units repel dirt and dust, occasional wiping and cleaning are recommended. Warm solutions of any glass cleaning agent without aggressive chemical additives can be used. Various glass-cleaning agents are available at household goods stores.

7. Care for Windowsills and Sills

Sills and windowsills do not require special care. Wipe them with a damp sponge and a small amount of liquid detergent when they become dirty.

8. Regular Ventilation of the Room

uPVC windows are airtight and let in very little air when closed. Consequently, moisture accumulates indoors, especially in kitchens during cooking. It may condense on the coldest parts of the window—glass panes. To prevent this, it's recommended to ventilate the room three times a day for 15 minutes each time by fully opening the window.
