Warm-edge spacer for IGUs

The company’s Thermal Spacer-VTS technology replaces the traditional combination of metal spacer, desiccant, and primary sealant with a single component. 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. The primary seal, backed by the company’s 12-yr. warranty, is said to have 35% 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. VTS is available for any size IGU to130 x 236-in. maximum and can be combined with other fabrication options including lamination, silk-screen or digital print, and glass coatings that can be applied to a variety of tinted substrates.
