More informationA spacer bar is a critical component within insulating glass units (IGUs), used to separate the panes of glass and create the insulating cavity between them. This cavity plays a key role in improving thermal performance and energy efficiency in modern glazing.
Certain spacer bar types also contain a desiccant material, which absorbs any moisture trapped within the sealed unit. Small perforations along the spacer bar allow the desiccant to effectively remove water vapour, helping to prevent internal condensation and maintain long-term clarity and performance.
Construction & Design
Spacer bars are manufactured into a frame that sits between the glass panes. The frame is slightly smaller than the glass unit, allowing the perimeter sealant to bond securely around the edges.
Warm edge spacer bars are designed to improve thermal efficiency at the edge of the glass unit, the area where the most heat loss occurs.
Often referred to as a thermal break, warm edge technology:
Key construction features of Warm Edge Spar include:
This ensures both structural integrity and consistent performance across all sealed units.
Regency Glass uses advanced TPS® (Thermo Plastic Spacer) technology as a high-performance alternative to traditional spacer bars in our fully automated TGU production lines.
TPS® acts as both:
Applied using a fully automated robotic process, TPS® offers:
