Introduction to Aluminium Spacer Bar
Aluminium spacer bars are essential components in the production of insulating glass units (IGUs). They serve as the separator between the two or more glass panes in an IGU, creating a sealed chamber that is typically filled with an insulating gas such as argon or krypton. This design significantly improves the thermal insulation and soundproofing performance of the glass, making it a popular choice for energy – efficient buildings. Aluminium spacer bars are favored for their lightweight, corrosion – resistance, and ease of fabrication. They can be customized in various shapes, sizes, and finishes to meet different architectural and design requirements. Aluminium Spacer Bar
