SST Non-Metal Spacer-sst provides the highest resistance to conduction and eliminates metal to glass contact and conduction.
Many windows are constructed with a metal spacer between the panes to give them the insulating glass unit structural stability. Unfortunately these metal edges conduct cold from he outside of your home at a rate up to 120% higher than at the center of the glass are. 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 and reducing stress on glass panes.
