In the process of urbanization, large office buildings and high-rise commercial buildings often feature glass curtain walls. Many clients prefer to use glass curtain walls because of their bright and shiny appearance, which gives the whole building a tall and luxurious feel. Glass curtain walls are a new type of wall that combines aesthetics and energy efficiency. So what are the advantages of glass curtain walls? How should we maintain and care for them?

Advantages of glass curtain walls

  • Good lighting and vision: Glass has strong light transmission properties and can project natural light from outside to inside during the day, making the entire indoor space bright and spacious. At night, the indoor light scatters from inside to outside, and the reflective properties of the glass curtain wall provide a dynamic beauty that changes with the lighting from the sun or artificial light.

  • Novel appearance and flexible design: Glass curtain walls are smooth and regular, and under the irradiation of natural light, they make the entire building look tall and luxurious.

  • Insulation: Glass curtain walls can keep the building warm in winter and effectively block the entry of cold air from outside.

Maintenance of glass curtain walls

Because glass curtain walls can be affected by natural environmental factors for a long time, the adhesive will age and fail, and the glass curtain wall may fall. However, most curtain walls will try to use transparent or semi-hidden frame glass curtain walls during design to greatly reduce the probability of glass falling due to the support and restraint of the framework.

When the use of glass curtain walls reaches a certain age, water seepage is a common phenomenon. Relevant materials must be chosen according to national standards during construction to reduce the probability of leakage. Therefore, curtain wall maintenance must be carried out when the building is delivered and used for more than 10 years. Sampling inspections of silicone structural sealants on different parts should be conducted, followed by inspections every three years.

In addition to routine maintenance of glass curtain walls, specialized institutions must be contacted for testing, identification, and maintenance of curtain walls in the following special situations: abnormal use of the curtain wall is discovered; abnormal deformations, detachment, and cracking occur in panels, connecting components, and local walls; structural safety hazards are detected in the main building structure; damage due to natural disasters such as typhoons, strong winds, and earthquakes or safety accidents such as fires and explosions.
