The following are some common problems of glass curtain walls:

1. Aging and cracking of sealants

In long-term use, sealants will be affected by factors such as climate and ultraviolet rays, leading to aging and cracking. This may cause the sealing performance of the curtain wall to deteriorate, leading to problems such as rainwater leakage and air infiltration. For example, on the glass curtain walls of some high-rise buildings, after years of wind and sun, cracks appear in the sealants, allowing rainwater to penetrate into the room during the rainy season, damaging the wall and decoration.

2. Self-explosion of glass

The glass itself may have quality defects, or be subjected to uneven stress during installation and use, resulting in self-explosion. Self-exploding glass not only affects the appearance, but also poses a threat to people and property. For example, on the glass curtain wall of a commercial building, a piece of glass suddenly exploded, and the falling fragments almost hit passers-by.

3. Hardware damage

Hardware connecting the glass and the frame, such as screws, hinges, etc., may be damaged due to corrosion, fatigue, etc., thus affecting the stability of the curtain wall. For example, in some buildings in coastal areas, due to the high salt content in the air, the hardware is easily corroded, causing the glass to loosen.

4. Structural deformation

Deformation and settlement of the main structure of the building, or unreasonable structural design of the curtain wall itself, may cause deformation of the curtain wall structure. This will affect the appearance and performance of the curtain wall, and even pose a safety hazard. For example, in earthquake-prone areas, if the curtain wall structure design does not fully consider the seismic factor, it may be severely deformed during an earthquake.

5. Difficult cleaning and maintenance

Glass curtain walls are usually high in height, and cleaning and maintenance are difficult. If they are not cleaned for a long time, dust, stains, etc. will affect the transparency and beauty of the curtain wall. For example, the glass curtain walls of some high-rise buildings are difficult to clean, and the surface is covered with dirt, which affects the overall image of the city.

6. Energy consumption problem

The poor thermal insulation performance of some glass curtain walls leads to overheating in the summer and overcooling in the winter, which increases the energy consumption of air conditioning and heating. For example, some curtain wall buildings with ordinary single-layer glass have significantly higher indoor temperatures in summer than other buildings, and the energy consumption of air conditioning has increased significantly.

7. Light pollution

The reflection of light by glass curtain walls may cause light pollution, affecting the surrounding environment and the lives of residents. When the sun is strong, the reflection of light by large areas of glass curtain walls may cause glare to drivers and affect traffic safety.

These are the common problems of glass curtain walls, which need to be paid attention to during the design, construction and use process, and corresponding measures should be taken to prevent and solve them.
