Are your glass doors and windows ready for winter?

Winter is coming, are your glass doors and windows ready for it?

Although you can use heating indoors to keep warm, the house with poorly sealed doors and windows still feels very cold, especially for old houses. If the windows are not tight, the cold wind will come in from the window gap.

In this article, I will introduce how to make your home warmer in winter, what makes doors and windows leak, and how we solve the problem of leaks in doors and windows.

How to make your home warmer in winter

1. Proper use of seals

If your glass doors and windows are not tightly sealed, one of the reasons could be the aging of the sealing strip. You can usually find them at the connection between the glass of the window and the window frame. In the process of using windows, the owner often opens and closes the windows and wears the sealing strips.

In addition to the long-term accumulation of dust, the friction on the sealing strips is increased, which causes the window’s ability to block wind and sand. For weathered seals, owners can go to the building materials market to buy good quality seals. If the owner does not have installation experience, ask the sales staff for the installation method in detail and then install it by themselves.

Before installation, remove the old seal and carefully remove the debris in the slot. At the same time, the sealing strip cannot be pulled too tightly during installation, just insert the new sealing strip and tap it.

Another situation is that the old house is more likely to appear. Due to the long life of the house, the wall may become loose, and the seal between the window frame and the wall is reduced, resulting in wind drilling from the crack. In this case, consumers can contact a professional for repairs, or consumers can buy a foam glue on the market and seal it by themselves.

2. Increase the number of glass layers to keep warm

Single-layer windows may have a tight seal. Meanwhile, you can also increase the number of glass layers to achieve thermal insulation.

Add glass to the original frame of your glass doors and windows, change the original single-layer glass to double-layer insulating glass.

After installation, the worker must carefully check the details, especially the tightness of the window, whether the window sash is flexible to open and close, and whether the window is airtight when closing.

3. Replace thick curtains

In addition to sealing window gaps, you can also replace thick curtains to withstand cold winds. The thick curtains in winter can not only adjust the light but also block the wind.

There are a few things to know when choosing curtains.

First of all, the windows must be sealed, and it also needs to coordinate with the interior decoration and furniture style of the entire room.

Choose your curtains also according to the orientation. The south-facing windows are sunny and there are many options for winter curtains; but in the north-facing rooms, there is not enough light and the curtains are warm. The curtain can be made of warm materials such as cotton or flannel.

From a design perspective, buyers want to increase the warmth of the interior, and can also achieve the warm living effect through the later soft installation.

Causes of windows and doors leaking in winter

1. Uneven profiles of doors and windows

The main reason for the leakage of doors and windows is the closeness between the doors and windows and the frame. The flatness of the profile is an important factor affecting the closeness. If the flatness of the profile is insufficient or deformed, there will be a certain gap between the door and window fans and the frame, causing air leakage.

2. A defective or aging sealing strip

The sealing strip is the key to the sealing of doors and windows. At present, the quality of the sealing strip on the market is very different. High-quality sealing strips have strong toughness, high wear resistance, and are not easy to break; while poor-quality sealing strips are very fragile, easily corroded and broken, and cannot achieve the sealing effect. If the sealing strip is not installed properly, unevenness or bulging may cause air leakage.

3. Cracks between the frame and the wall

During the installation of doors and windows, many winter door and window sealing workers did not do a good job of sealing the door frame, window frame and wall due to rushing or cutting corners. Especially in the old house, the wall loosens during the settlement process, and the closeness with the door and window frame is reduced.

If the waterproof glue is not applied evenly, the sealant is not adequately made, or the expansion bolts are not nailed, it will make the frame and the wall unable to “closely fit.” In summer rainy weather, the rubber tends to collapse, and in autumn and winter, it causes wind leakage.

4. Weak hardware lock

The quality of door and window hardware is also closely related to the sealing performance. Especially for casement windows, it relies on the transmission of the hardware to seal. If the transmission is of poor quality, it is easy to leak air from the edge of the sash.

The hardware of glass doors and windows currently on the market are divided into domestic and imported. Domestic hardware usually has two upper and lower lock points, while imported hardware usually has three upper, middle, and lower lock points.

The principle is that after the doors and windows are locked, the lock point and the lock seat are fastened together, and cooperate with the hinge or sliding brace to jointly generate a strong sealing pressure and elastically deform the sealing strip, thereby providing sufficient sealing performance for the doors and windows.

Therefore, the hardware with insecure locks will greatly reduce the sealing performance of doors and windows.

How to deal with window leaks before renovation

1. Select the window frame with cold-resistant function

When selecting the window frame, if you want to achieve the cold-resistant effect, the aluminum alloy of the broken bridge is preferentially selected. The heat-insulating aluminum profile improves the thermal insulation performance of the window, and its airtightness is relatively good, which can ensure that the indoor window sills and floors in dusty areas are not dusty.

If you choose a plastic-steel frame material, because the plastic-steel window has been used for a long time, the gap at the interface is too large to be bonded, and it is easy to ventilate. Therefore, when there is a leakage of air, first use a sponge to stick around the window, and then cover the entire window with plastic.

The plastic absorbs heat and is not airtight, and the temperature is maintained well. Select aluminum-wood windows, because aluminum-wood windows are covered with a layer of aluminum alloy in addition to solid wood. Doors and windows are more tightly sealed, which can effectively block the invasion of wind and sand, and will not freeze or dew in the cold winter. It also keeps noise out of the window.

2. Select vacuum glass for your glass doors and windows

Vacuum glass is preferred. The vacuum glass is similar to insulating glass, but its thermal insulation performance is better than insulating glass because the two sheets of flat glass in the middle of vacuum glass are sealed around, the gap is evacuated and the exhaust holes are sealed. The gap between the sheets of glass is 0.1-0.2mm, which is smaller than the insulating glass, and the insulation effect is good, but the price is more expensive.

Insulating glass has a moderate price and good thermal insulation performance, so it is widely used. The purchase requirements generally choose a 12mm hollow distance, and the glass on both sides should reach a thickness of 4 to 5mm.

The sealing structure of the insulating glass mainly includes a single-pass seal and a double-pass seal. It is recommended to use a double-pass seal. The first sealant prevents water vapor from invading, and the second sealant maintains the stability of the structure and continuously maintains heat.

If the window opens to the outside, a layer of window can be added to the interior, and if the window opens to the inside, an additional layer of a sliding window can be added to the outside.

Through two layers of windows, the thermal insulation effect of double glazing can be achieved.

3. Select casement window

A casement window is preferred. A casement window will be much better than a sliding window. Casement windows are generally sealed with rubber strips, and push-pull windows are sealed with wool tops.

Therefore, the casement window’s tightness and isolation from dust and rain are stronger than sliding windows; and casement windows are generally locked with two-point locks or heaven and earth.

The sliding window is closed with a hook lock or a touch lock, so the casement window is also much stronger in terms of airtightness.

How to fix window leaks after renovation

1. Old-fashioned window air leakage solution

For double-layer old-style windows, the solution to air leakage is to fill the gap between the window and the window with sawdust. The sawdust can solve the moisture of the window and block the strong cold air at the bottom of the window.

The window seams of such windows can be sealed with craft paper and paste to ensure high airtight temperature.

2. Solutions for air leakage in the window gap

If there is a gap between the window frame and the wall, clean up the gap, fill it with styrofoam, and then fill the gap with high-grade cement river sand, and then repair the surface; Leakage between the window frame and the seal can be considered.

If the gap is large, it is better to add a layer of plastic steel window to the original window.

3. Remaining problems in installing windows

First of all, it is necessary to look at whether the problem is left over by the workers when they are not installed or the product itself. If the product is the reason, you should find the dealer or the manufacturer.

If the worker has a little problem during the installation If there is something wrong, you can remove it and reinstall it.

Or you can first clear the gap between the window frame and the door cover and the wall, then plug it with styrofoam, then fill the gap with cement and sand. Go for repairs.


Generally all these below factors can affect your glass doors and windows.

Improper installation, quality of materials and failure of accessories will cause air leakage in doors and windows.

Check these points before installation to prevent problems and cause unnecessary trouble.

After all, in the cold winter, everyone wants to spend a pleasant time in the warm home interior.
