Vista’s Seal Smart Insulated Glass System combines Intercept® “warm-edge” spacer technology with multiple glass options that allow you to choose the right glass package for your home. We know that one size doesn’t necessarily fit all. This is why the Seal Smart family has numerous configurations, from a dual-glazed Low-E and Argon unit, to a triple-glazed package with two panes of Low-E glass and Krypton gas in both air spaces. The Seal Smart glazing system has a package to fit any energy need and budget.

Additionally, it offers the latest science in gas mixture and filling, OptiGas with ThermalCert, ensuring that the gas you were promised is actually going to bring you the energy savings you expect.

Contact Certified Window Wholesalers to determine which Seal Smart package is best for your home.
