The regular service life of U profile glass ranges from 20 to 30 years. Its specific duration is directly affected by four major factors: material properties, installation technology, service environment and post-maintenance, so it is not a fixed value.
I. Core Influencing Factors
Quality of the material itself The purity of the base glass, the anti-rust grade of the wire mesh (for reinforced type), and the aging resistance of supporting materials such as sealants and gaskets are the foundation for determining the service life. For example, glass made from high-purity quartz sand is more resistant to weathering than glass with more impurities; weather-resistant silicone sealants have a service life 5 to 10 years longer than ordinary rubber gaskets.
Standardization of installation technology If the frame is not fixed firmly or the glass joint gaps are not sealed tightly during installation, rainwater leakage or air ingress will occur. In the long run, internal metal parts are prone to rust, and the glass edges may crack due to repeated thermal expansion and contraction, which directly shortens the service life.
Erosion degree of the service environment
In outdoor applications, high salt spray in coastal areas and acidic gases in industrial areas will accelerate the corrosion of the glass surface and the aging of sealing materials, and the service life may be 30% to 50% shorter than that in dry inland areas.
Humid indoor environments (such as bathrooms and swimming pools) will also affect the seals at the glass joints, requiring additional anti-corrosion treatment.
Frequency and quality of post-maintenance Regular inspection (recommended every 2 to 3 years) of whether the sealant is cracked, whether the glass surface has scratches or damages, and timely replacement of aging components can effectively extend the service life. If there is no maintenance for a long time, problems may cause chain damage and lead to early replacement.
II. Key Measures to Extend Service Life
Early selection : Prioritize the use of reinforced U profile glass(with wire mesh) and match it with supporting materials with strong weather resistance (such as EPDM rubber gaskets and neutral silicone sealants).
Installation control : Choose an experienced construction team to ensure the frame is fixed firmly and the joints are sealed completely, so as to avoid potential leakage problems in the later stage.
Daily maintenance : Regularly clean the glass surface (avoid using highly corrosive cleaning agents), check the status of sealants and connectors, and repair in time if problems are found.
