Although the glass curtain wall is beautiful, it will always age. After being exposed to wind and rain for a period of time, the glass curtain wall will inevitably have some problems as it ages or is eroded by the external environment. Regarding the safety, function and benefits of the glass curtain wall, it is necessary to replace the glass curtain wall in time. So when does the glass curtain wall need to be replaced? Zhongdong Curtain Wall will take you to reveal the logic of replacing the glass curtain wall today.
1. Replacement of aging glass curtain wall strips
1. Since the glass curtain wall is usually exposed to the outside, long-term sunlight, temperature changes and water vapor will cause the silicone weather-resistant sealant to harden, crack, powder, debond, lose sealing elasticity, and cause the sealant to age and fail. This result will reduce the strength of the sealant and the loss of adhesion is a huge safety hazard. If the strip is found to be aging, it needs to be replaced in time.
2. Self-explosion of glass curtain wall
Since most of the glass used in glass curtain wall is tempered glass, the inherent nickel sulfide impurities in the production process of tempered glass cannot be completely removed, which may lead to unpredictable self-explosion. At the same time, due to the large temperature difference between hot and cold, the glass is stressed and ruptured. If the glass is broken at this time, it needs to be replaced in time.
3. Glass curtain wall support structure
The glass curtain wall support structure is mainly aluminum profiles or steel. Aluminum profiles are susceptible to electrochemical corrosion in coastal areas. After the anti-rust coating of steel is damaged, rust is prone to spread, which seriously weakens the bearing capacity. This situation usually rarely occurs. If it occurs, the glass curtain wall may have to be dismantled and rebuilt.
So why must the missing glass curtain wall be replaced?
1. Safety requirements
Problems can easily cause the glass used in the glass curtain wall to fall. The main manifestations are failure of structural adhesive, loosening of fixings, failure to deal with self-explosion/breakage of glass in time, and broken hardware. These may cause glass panels or window sashes to fall from high altitude, posing a fatal threat to pedestrians, vehicles, and property.
2. Loss of glass curtain wall function
Glass curtain wall glue strips are aged and prone to leakage: Continuous leakage not only damages interior decoration (ceiling, wall, floor), equipment (electrical, HVAC), but also breeds mold, endangers health, destroys building use function, and reduces property value.
