When autumn and winter arrive, rooms with poorly sealed doors and windows can feel extremely cold, especially in older homes. Wind often slips through cracks in the windows, bringing in not just cold air but also dust. Keeping your home warm and protected from the elements starts with ensuring your doors and windows are properly sealed. A cost-effective solution is to replace window seals or reapply sealant. If you're on a tighter budget, consider upgrading to energy-efficient windows or security doors, along with heavy curtains that help block out the chill and wind.
**â– Warmth-Boosting Tips**
**Seal the Gaps to Prevent Drafts**
During colder months, especially in places like Beijing where the wind is strong, you might feel a cool breeze even if you can't see where it's coming from. To identify the source, run your hand along the window edges. Two common issues usually cause drafts: one is the aging of the rubber sealing strip between the glass and the frame, which can wear down over time and lose its effectiveness. The other is loose gaps between the window frame and the wall, allowing wind to seep in.
**Solution:** For worn-out sealing strips, you can purchase new ones from a hardware store and install them yourself. They’re easy to replace—simply remove the old strip with a screwdriver and insert the new one into the groove. For gaps between the frame and the wall, clean the area thoroughly and apply a layer of glass sealant around the frame. Keep the sealant layer about 5–10 mm wide for best results.
**Budget:** Sealing strips cost under ¥10 per meter, while sealant is around ¥20 per tube.
**Note:** Not all windows need immediate repairs. If the existing seals are still in good condition and there’s no noticeable draft, there’s no need to replace them. However, if the gap between the frame and the wall is large, it’s better to consult a professional to fill it with foam for a more secure fit.

**Upgrade Windows or Add Glass Layers**
Older homes often have single-pane windows that don’t provide much insulation or soundproofing. Adding an extra layer of glass can significantly improve thermal efficiency. However, simply adding glass to an existing frame may not be practical due to size and weight issues. It’s often better to replace the entire window or add a second layer of windows for better performance.
**Solution:** Replacing the window involves measuring, custom manufacturing, and installation. If you choose to add a second layer, make sure the frame can support the extra weight. For outward-opening windows, you can add an inside window; for inward-opening ones, a sliding window outside works well. Both options help create a double-glazed effect, improving insulation and reducing noise.
**Budget:** Plastic steel windows cost around ¥300 per square meter, while broken bridge aluminum windows range from ¥500 to ¥800 per square meter.
**Tip:** Always check the quality of new windows, especially the thickness and safety certifications of the glass. Ensure the hardware functions smoothly and the window closes tightly.
**Use Thick, Insulating Curtains**
Winter curtains are more than just decorative—they play a key role in keeping your home warm. Thick, long curtains can effectively block cold air and reduce drafts. Choosing the right fabric, color, and size is important to both enhance warmth and match your interior decor.
**Solution:** Opt for heavier materials like cotton or flannel, especially for north-facing windows that tend to be colder. Darker colors help retain heat and blend well with the room’s style. These materials not only insulate but also offer some dust and noise protection.
**Budget:** Curtain prices vary widely, from a few hundred to several thousand yuan per square meter, depending on the material and design.
**Tip:** In addition to curtains, consider updating other soft furnishings such as pillows, cushions, or lighting. Warm-toned lamps and matching fabrics can further enhance the cozy atmosphere of your space.
**â– Additional Tips**
**Avoid Sliding Windows for Better Insulation**
While sliding windows are convenient and take up less space, they are not ideal for insulation. When closed, they often leave small gaps between the two panes, allowing cold air and rain to enter. For better thermal performance, it's better to choose hinged windows that close more tightly.
**Plan Installation Wisely**
Window replacement requires careful timing. After measurements are taken, the installation process can be affected by weather conditions. Windy days may complicate the work, and high floors increase risks for workers. It’s best to schedule the project early to avoid delays.
**Don’t Over-Spend on Screens**
When replacing windows, screen windows are often included. However, these are frequently used and prone to wear. Instead of buying expensive specialized screens, opt for regular ones that can be replaced every year or two. This saves money without sacrificing function.
**Choose Warm Door Materials**
Old security doors were often thin and offered poor insulation. Even adding a wooden door inside doesn’t always solve the problem. If possible, invest in a high-quality security door with good insulation properties. These doors are designed to keep the cold out while maintaining a stylish appearance.
