Learn about Viracon's newest spacer - VTS™ - engineered to outperform

Insulating glass consists of two or more plies of glass enclosed by a spacer. Inherently, insulating glass increases a window's thermal performance by reducing the heat gain or loss.

At Viracon, insulating glass units are sealed with a primary seal and a secondary seal of silicone. Insulating units are designed to absorb stress on the unit caused by thermal expansion and pressure, provide a barrier to water and moisture infiltration, provide a gas-tight seal to prevent loss of any specialty gas fill and create a barrier that reduces condensation.
