What happens when the bedroom window glass cracks in winter?

This is due to the size of the glass being too tight or shrinking.

Leave too small to fit the local temperature difference. In winter, when the temperature is relatively low, the window glass will self-crack. Insulating glass.

There is damage during the production process, and after the temperature changes, the glass cracks from the wound point, and it can also cause self-cracking.

In addition, there are many reasons why the glass of the window itself is broken, some are external reasons, and some are internal reasons, and if the glass is too tightly inlayed, it can also cause the glass to break. If the weather is too cold, the glass will break, and it will also break if it is heated unevenly. It is better to repair it as soon as possible, so as not to be very bad in the winter.

Precautions to prevent glass breakage

First, there are quality problems in the glass itself, such as the glass contains stones.

Air bubbles and impurities, which are the weak points of the glass, are also an important cause of glass bursting.

2. In the process of glass processing, due to improper operation, the glass has a deep burst edge problem, or there are scratches, etc., which will also lead to glass bursting.

3. During the transportation of door and window glass, if it is damaged due to poor packaging, the damaged part will change the internal stress of the whole glass. When used on the wall, the internal stress of the glass can also cause it to burst.

Fourth, improper installation of doors and windows can also cause glass bursting. For example, the size of the door and window glass is not suitable and the installation is too tight, which leads to the change of stress inside the glass.

Reasons why the window glass cracks on its own:

1. The size of the insulating glass is too tight or the shrinkage is too small, which is not suitable for the local temperature difference. When the temperature is relatively low, the window glass will self-crack.

2. The insulating glass is damaged in the production process, and after the temperature changes, the glass cracks from the injury point, and it may also cause self-cracking.

Window glass maintenance.

The first trick: wipe the wooden door with a cotton cloth.

When dealing with surface stains, you need to use a soft cotton cloth to wipe it to avoid scratching the surface with a hard cloth; When the stain is too heavy, you can use a neutral cleaner, toothpaste or special cleaning agent for furniture, remove the stain and then dry wipe it; Note that the cloth soaked in neutral reagent or moisture should not be placed on the surface of the wooden door for a long time, otherwise it will damage the surface and make the surface material discolored or peeled; Pay attention to the edges and corners of the wooden door should not be rubbed too much, otherwise the edges and corners of the paint will fall off.

The second trick: plastic wrap skillfully helps the windows to remove oil.

Doors and windows can be wiped clean with a cloth moistened with vinegar water. If the window is stained with oil, you can spray the glass with detergent first, and then paste plastic wrap to soften the solidified oil stains, and after ten minutes, tear off the plastic wrap and wipe it with a damp cloth.

1. Cracking caused by resonance.

If it is bonded with the wall, the wall must be flat, and the glass and the wall must be bonded as a whole, especially the house by the road or subway track, the resonance in these places is great. So most likely it is resonance-induced cracking.

2. Glass aging.

The quality of the glass is not very good, it may also be that it has aged for a long time, the glass is cracked, and the glass can only be replaced, there is no other way. For safety reasons, explosion-proof film can be glued temporarily to prevent broken glass from falling.

3. The temperature difference is too large.

The temperature difference between indoor and outdoor is too large, which leads to uneven heating of the glass, which leads to cracking.

Ways to prevent glass self-breaking:

1. There is no elastic material isolation between the glass and the bottom of the cabinet door and the bead, so that direct contact is easy to cause the glass to break; If the glass is loose or the nails are fixed too tightly, the vibration when the door is opened and closed can easily cause the glass to break. Therefore, there is a certain amount of flexibility during installation to prevent the glass from cracking.

2. The glass cutting is too large, there is no margin for the edge, and the glass is directly pushed into the door notch or hard embedded in the groove during installation, then, due to the temperature difference, the glass will be damaged if it is squeezed. Therefore, there must be a margin when cutting, not too large.

3. When cutting glass, each side should be reduced by 3mm according to the size of the notch, so that there is a gap between the glass and the notch to meet the needs of deformation. When installing the glass, it should be filled with elastic materials, such as putty, rubber strips, sealants, etc., so that the glass is isolated from the door notch and the bottom of the groove, and is in an elastic and fixed state to avoid glass fragmentation caused by collision.

Yes. Glass is a poor conductor and is fragile. When the temperature difference between the inside and outside of the glass is too large, and the expansion inside and outside is inconsistent, bursting will occur.

Because glass is a mixture, amorphous, there is no fixed melting boiling point. It is recommended to replace the windows with tempered glass, which will not be frozen and cracked. Usually do not force the glass surface, in order to prevent scratches on the glass surface, it is best to lay a tablecloth.

When placing things on glass furniture, handle them with care and avoid collisions.

Why does the glass crack in winter: The heat of the glass is transferred from the inner wall to the outer wall at a slow speed, the temperature difference between the inside and outside is large, and the temperature of the inner wall expands high, while the temperature of the outer wall has not risen, basically does not expand, and the expansion degree of the inner and outer walls is inconsistent, so it is easy to crack. This is what is commonly referred to as thermal expansion and cold contraction.

In winter, the outer side of the glass breaks first, and when hot water is poured into the glass, the temperature of the inner wall of the glass rises sharply, but because the glass is not a good conductor of heat, the temperature of the outer wall of the glass does not change much, and the temperature difference between the inner and outer walls of the glass is very large.

Whether the window glass you change is insulating glass. If so, it is that the insulating glass he made is not tightly sealed, that is, it is unqualified, because of the weather, the heat exchange is cold outside and hot inside, and the inner glass has cracks, and the window can be replaced.

There are three reasons for this:1. Affected by external forces. When glass is heated, the heat is not evenly distributed.

At this time, the glass will be affected, resulting in a self-explosion phenomenon. It may also be caused by sun exposure, sediment impact, and large bumps in the vehicle.

2. Affected by the weather. Summer and winter are the seasons when there are more glass self-explosions, and the glass on the bay window and curtain wall is more likely to self-explode in summer, while the shower room occurs more in winter. The large temperature difference between inside and outside is an inducing factor for the self-explosion of tempered glass.

In summer, if the outdoor temperature is too high, the indoor air conditioning temperature is very low, and the glass is cold and hot on both sides, and the force is uneven, the probability of self-explosion will increase.

3. It may also be a quality problem of the glass itself. The self-explosion of glass has a lot to do with its own quality problems. If the tempered glass itself contains more impurities, the probability of self-explosion will increase a lot.

1. There are stones, bubbles and impurities in the glass;

2. The glass contains nickel sulfide crystals;

3. In the process of processing, transportation, storage and construction, the surface and edge of the glass may cause defects such as scratches, explosions and edges, which are easy to cause stress concentration and cause the tempered glass to crack;

4. The tempered glass needs to be heated and cooled in the production process, and the uneven direction along the glass plate surface and the asymmetry along the thickness direction of the glass during heating or cooling will lead to uneven stress along the plate surface and asymmetrical stress distribution along the thickness direction, which may cause the tempered glass to crack.
