Insulated Glass Packages with SST Energy-Saving Foam Spacer System
Many windows are constructed with a metal spacer between the panes to give the insulating glass unit structural stability. However these metal edges conduct cold from the outside of your home at a rate up to 131% higher than the SST foam spacer. 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, the SST warm-edge spacer design also minimizes the subtle movement of glass panes caused by changes in temperature, helping to prevent seal failure and reducing stress on the glass panes.
