Viracon, a single-source architectural glass fabricator, has announced that it has begun production of insulated glass units with the Viracon Thermal Spacer - VTSTM, a new thermal spacer technology available exclusively through Viracon. VTS replaces the traditional combination of metal spacer, desiccant and primary sealant with a better-performing single component. VTS’s seal integrity is supported by a 12 year limited Viracon Thermal Spacer (VTS) Insulating Glass Seal Warranty. The proprietary formulation of VTS consists of a black thermoplastic elastomer with integrated desiccant and primary sealant that is chemically bonded directly to the glass and secondary sealant.
This technology has been engineered to outperform conventional and other thermoplastic spacer systems.
“VTS delivers a superior primary seal, desirable aesthetics, and better thermal performance” says Sara Theis, product manager with Viracon. “The primary seal, backed by our special 12 year warranty, has 35 percent better argon retention and increased stability in extreme hot or cold temperatures. The extrusion method for the thermoplastic material results in a smooth, continuous, matte black finish without shine, perforation marks or seams and there is no separate PIB component so there can be no PIB movement. In addition, edge deletion is placed within the VTS, improving the edge of glass aesthetics. Thermal performance is 14.4 percent better than aluminum spacers and condensation resistance is notably higher. We believe every project should take a hard look at the benefits of VTS.”
VTS is the newest addition to Viracon’s spacer offering which includes aluminum, stainless steel, and ExtremEdge. VTS’s exclusive technology delivers the best thermal performance. It is available in a range of thicknesses; it improves edge of glass aesthetics; and units produced with VTS include an argon fill.
VTS is available for any size IGU up to130 inches by 236 inches maximum. It can be combined with Viracon’s other fabrication options including lamination, silk-screen or digital print, and the broad selection of Viracon’s proprietary glass coatings that can be applied to a variety of tinted substrates. With all these options designers have exceptional versatility to deliver striking aesthetics with the superior energy performance of VTS.
