Winter is here—are your home’s doors and windows well-insulated?
Release date:

As October arrives, the weather grows cooler day by day, bringing winter ever closer. If your home’s doors and windows aren’t properly sealed at this time, you’ll start feeling chilly drafts—especially in older homes where aging windows and doors have developed large gaps. Cold winds, often mixed with dust and sand, sneak into the house, not only failing to keep it warm but also making a mess of your living space.
If conditions permit, we recommend replacing your aging doors and windows early in autumn or winter. If that’s not feasible, you can start by updating the window seals, reapplying window sealant, and then installing a set of heavier curtains—this will help keep cold drafts from sneaking indoors.
Seal window gaps to prevent drafts
Do any of you ever feel this way? In autumn and winter, when sitting by the window, you can clearly sense cool breezes trickling down your back. This phenomenon usually occurs in one of two ways: either the sealing strips around the window’s glass and frame have aged over time, accumulating dust during prolonged use and gradually wearing out—thus reducing their ability to block wind and dust—or perhaps the wall has become loose, causing the window frame to lose its tight seal with the surrounding masonry, allowing drafts to sneak in through the cracks.
Solution: For the first scenario, you can purchase sealing strips from a building materials market and either install them yourself or hire a professional to do it for you. Self-installation is also quite simple—glass sealing strips are made of rubber and slot neatly into the grooves along the edges of the glass. To replace them, just use a screwdriver to gently pry them out, then slide in the new strip and press it firmly into place.
For the second scenario, you can either contact a professional to reapply the sealant at your home or tackle the task yourself. The process is straightforward: after lightly cleaning the joint between the frame and the wall, apply glass sealant evenly along both the inner and outer edges of the frame. Make sure the sealant layer is about 5–10 millimeters wide for optimal results.
Warren reminds you: The use of seals and sealants should depend on the extent of window damage. For instance, if some seals are still intact and there’s no air leakage even during windy conditions, you may not need to replace them—repeatedly removing and reinstalling them could actually hinder proper sealing of the gaps. However, if cracks between the frame and the wall are severe, it’s recommended to contact a professional who can carefully reapply expanding foam to ensure a strong, durable bond between the frame and the wall.
Replace windows or increase the number of glass layers
Many older homes still have single-pane windows, which offer poor soundproofing and insulation. Some people hope to improve thermal performance by adding more layers of glass. However, if you simply add extra panes to the existing frame—such as replacing the original single-layer glass with double-glazed, insulated glass—the profile dimensions might no longer match. Moreover, the added weight from the extra glass could make the window much harder to open and close. Therefore, it’s generally recommended to either replace the entire window or install an additional layer of glazing for better results.
Solution: The implementation steps for replacing windows and adding an additional layer of windows are essentially the same, including preliminary on-site measurements and factory fabrication. However, during the final installation phase, replacing existing windows requires removing the old ones entirely, whereas adding an extra layer involves simply installing the new window directly over the existing one.
The entire process typically takes about 10 to 15 days, though both the measurement and removal/installation can be completed within a single day. If your windows open outward, you can add an inner layer of windows from inside the room. For inward-opening windows, consider installing a sliding window system on the exterior side.
By using this double-layered window setup, you can achieve insulation comparable to that of double-glazed windows. As for the window material, we recommend choosing broken-bridge aluminum for optimal performance.
Warren reminds you: Be sure to carefully inspect newly installed windows—especially when adding new ones. First, verify the glass thickness and check for safety markings. Then, thoroughly examine the window hardware: test whether the sash opens and closes smoothly, and ensure the window seals tightly when closed, providing a draft-free fit.
Replace with thick curtains
Unlike the lightweight sheer curtains of summer, autumn and winter curtains not only help regulate light but also provide excellent wind-blocking and insulation when paired with a heavy, extra-long set. However, choosing the right texture, size, and pattern for your curtains requires careful consideration—after all, they should not only effectively cover the windows but also harmonize seamlessly with the room’s overall decor and furniture style.
Solution: When choosing curtain fabrics for winter, prioritize materials that are both thick and warm—but also consider the room’s orientation. South-facing windows bask in ample sunlight, offering a wide range of fabric options for the colder months. In contrast, north-facing rooms tend to feel chilly and gloomy, so it’s crucial to select curtains carefully. Opt for deep, warm-colored fabrics, and consider materials like cotton or velvet, which provide superior warmth. Beyond their insulation benefits, these fabrics also offer excellent dust-proof and soundproofing properties.
Besides curtains, you can also enhance a room’s warm ambiance by making subtle changes to other soft furnishings inside. For instance, opt for throw pillows or cushions in colors or materials that complement the curtains, or choose lighting fixtures that emit softer, warmer-toned light—preferably with a focus on hues like amber or gold—to create an even cozier atmosphere.
