Insulated Glass Quality: Why the Aluminium Spacer Bar is Critical
The Aluminium Spacer Bar is the backbone of insulated glass longevity, preventing moisture penetration and fogging.
4 Quality Indicators for Aluminium Spacers
1. Uniform Porosity
High-quality spacers require consistent and transparent air holes. Poor porosity reduces desiccant efficiency, leading to internal condensation.
2. Surface Cleanliness
Dirty surfaces prevent Butyl sealants from bonding correctly. Our spacers guarantee a surface free of oil, dust, and impurities for a lifelong seal.
3. Structural Integrity
A square profile ensures even support. Poorly formed spacers deform under wind pressure, risking glass breakage and seal failure.
4. Seamless High-Frequency Welding
Welding is the most difficult stage of production. JI'AN High-Frequency Seamless Welding provides a flat back with no protrusions, ensuring zero cracks during bending and superior sealing performance.
