Insulated Glass Window Spacer

The basic function of the spacer bar is to maintain a constant distance between the glass panes e g.

Insulated glass window spacer.

Color material and thickness. Inherently insulating glass increases a window s thermal performance by reducing the heat gain or loss. The space between the two panes of glass is filled with air which provide insulation. 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.

Insulated glass panels consist of two panes of tempered glass separated by a spacer. Polysulphide or silicone located below the spacer bar. Viracon s insulating glass spacers are available in two colors three materials and a variety of thicknesses. At viracon insulating glass units are sealed with a primary seal and a secondary seal of silicone.

If the material conducts less heat or cold than a conventional aluminum spacer at the edge of the glass it is said to be warm edge most of these newer spacers are less conductive and outperform pure aluminum. These are most often used in residential window applications. Latter is additionally prevented by secondary sealant e g. When specifying an insulating glass unit it is necessary to specify all three.

Spacers are a critical part of every window unit. 12 14 16 18 mm and to prevent the release of the inert gas argon krypton out of the cavities between glass panes. They separate the panes of glass providing the insulating glass unit within the window with structural integrity along with a thermal and moisture seal that enhances the window s thermal performance. Insulating glass consists of two or more plies of glass enclosed by a spacer.
