How to prepare windows for winter: sealing and insulation

With the onset of cold weather, it is especially important to properly prepare windows for winter in order to preserve heat and prevent energy leakage. Even quality plastic windows lose their tightness over time, and wooden structures require regular maintenance. Properly adjusting your windows for winter and insulating the jambs will help protect your home from drafts and improve its energy efficiency.

Why is it important to prepare windows for winter?

Without proper maintenance, windows can become a source of heat loss and discomfort. Preparing double-glazed windows for winter allows you to eliminate minor faults, improve air tightness and extend the service life of the structures. It also helps to prevent condensation and freezing of window frames.

How to prepare plastic windows for winter?

1. Check the seals. The seals wear out over time and lose their elasticity, resulting in draughts. Clean them of dirt and treat them with a special product to restore flexibility. If the seals are damaged, they must be replaced.
2. Adjusting the sashes for winter. A tight fit of the sashes is important to keep the heat in. Adjust the windows by changing the level of pressure with an adjusting wrench to eliminate gaps.
3. Clean and lubricate the hardware. To ensure that the hardware works properly even at low temperatures, clean all moving mechanisms from dust and dirt and lubricate them with silicone grease.
4. Insulate the jambs. Heat leakage often occurs through the slopes. You can use foam or special panels to insulate them.

Preparing wooden windows for winter

Preparing wooden windows for winter requires more attention than for plastic constructions. Wooden frames should be treated with anti-mildew and anti-moisture products to protect them from temperature fluctuations. It is also important to check the condition of the seals and renew the sealant if necessary.

Preparing double-glazed windows for winter

1. Checking the tightness of double-glazed windows. If condensation forms inside the double-glazed unit, it indicates a violation of tightness, and it will have to be replaced.
2. Cleaning the double-glazed windows. Wash the windows before winter so that dirt does not interfere with sunlight penetration and thermal insulation.
3. Check ventilation valves. Modern plastic windows are equipped with air inlet dampers. Make sure they are clean and working properly to prevent condensation.

Eliminate draughts and improve energy efficiency

Regular maintenance and proper window tune-ups can help prevent heat leaks and reduce heating costs. Insulating and sealing your windows will keep your home comfortable even on the coldest days. Additionally, you can use thermal curtains or window frame seals to improve insulation.

Conclusion

Proper preparation of plastic windows for winter includes checking the hardware, replacing the seals and insulating the jambs. Wooden windows require additional treatment to prevent damage from moisture and frost. Timely sash adjustment and window maintenance will help avoid drafts and improve energy efficiency
