Client News: Technoform Glass Insulation introduces new 1-inch-wide TGI-Spacer, providing high acoustical performance

Contributing to building occupants’ comfort, Technoform Glass Insulation North America, Inc., (TGI NA) now offers TGI(R)-Spacer in a 1-inch width for commercial and residential insulating glass products, such as windows, entrance systems and curtainwall. This new product not only optimizes thermal performance and condensation resistance, but also enhances acoustic performance for quiet interiors.

Blending naturally with any window frame, TGI-Spacer’s straight sightline and smooth matte finish complement insulating glass products’ appearance. TGI NA expands product design options with a new Dark Grey color added to its standard color palette, which also includes light grey, bronze, champagne, white and black. Custom colors are also available upon request.

Beyond aesthetics, independent laboratory testing validates that with this new 1-inch-wide TGI-Spacer and two lites of 0.25-inch glass (0.25-inch annealed/ 1.002-inch TGI-Spacer/ 0.25-inch annealed) a Sound Transmission Class (STC) rating of 35 and an Outdoor-Indoor Transmission Class (OITC) rating of 27 can be achieved.

“Reaching this exceptional level of acoustic performance is now possible without using any laminated glass,” says TGI NA’s product manager, Dheeraj Corepall.

Years of independent tests at the leading U.S. and global testing laboratories and use in the field have proven that TGI-Spacer meets or exceeds existing energy codes, as well as the most stringent industry standards for long-term unit durability, UV resistance, gas retention, fogging and moisture penetration.

With this newest addition, TGI-Spacers are available in widths ranging from 0.25 inch (6.35 mm) to 1.002 inch (25.45 mm). The patented design combines the benefits of high-performance polymers and thin stainless steel, setting the performance standard for insulating glass products.
