High Performance Spacer System

SST Non-Metal Spacer-SST Provides the Highest Resistance To Condution and Eliminates Metal to Glass Contact and Conduction.

Many windows are constructed with a metal spacer between the panes to give the insulating glass unit structural stability. Unfortunately these metal edges conduct from the outside of your home at a rate up to 120% higher than at the center of the glass area. This can create condensation problems at the window edge, damaging woodwork and draperies.

Preservation Windows combine a structural foam spacer with a seal of hot melt butyl to create a "warm" non-conductive edge, so Preservation Windows virtually eliminate condensation. And SST spacer's design also minimizes the subtle movement of glass panes caused by changes in temperature, helping to prevent seal failure by reducing stress on glass panes.
