Super Spacer® T-Spacer™

Quanex Super Spacer® T-Spacer™ is designed to satisfy the toughest commercial glazing demands, including silicone structural glazing (SSG), and can be seamlessly integrated into high-speed automated manufacturing thanks to an inner acrylic adhesive seal for immediate unit handling.

T-Spacer utilizes online PIB extrusion at the point of insulating glass (IG) manufacturing. Its triple-seal design is ideally suited to the challenges regularly met by commercial IG spacers and can offer a long-lasting solution for even the most architecturally innovative glass and glazing designs.

It has helped commercial buildings around the world boost their thermal performance while granting the benefits of large-format glass and glazing. For manufacturers and architects alike, T-Spacer is a true solution to every commercial IG need.
