Spacers

Spacer bars are essential components in the manufacturing of insulation glass units (IGUs), serving to separate the multiple glass panes and create a sealed air or gas space between them. These bars are typically made from materials like aluminum, stainless steel, or plastic, and are filled with desiccants such as molecular sieves to absorb moisture and prevent condensation within the IGU. The primary function of spacer bars is to maintain the structural integrity and precise spacing of the glass panes, ensuring consistent insulation performance. They also contribute to the thermal efficiency of IGUs by minimizing heat transfer at the edges, often incorporating thermal breaks or warm-edge technology to reduce energy loss. High-quality spacer bars are crucial for achieving the desired thermal and acoustic insulation properties, as well as prolonging the lifespan and clarity of insulation glass units.

 

Warm edge spacers for Insulating Glass Units (IGUs) are advanced spacers designed to improve the thermal efficiency of the unit. Unlike traditional aluminum spacers, warm edge spacers are made from materials with lower thermal conductivity, such as thermoplastics, or composite materials. This design minimizes heat transfer at the edges of the glass, reducing the risk of condensation and improving the overall insulation performance of the IGU. By maintaining a more consistent temperature across the glass surface, warm edge spacers contribute to better energy efficiency, lower heating and cooling costs, and enhanced comfort in buildings. Additionally, they help prolong the life of the IGU by reducing stress on the sealants and preventing moisture ingress, thereby enhancing the durability and performance of the insulating glass unit.
