How Allentown's Climate Affects Window Replacement
In Allentown's extreme winters, triple-pane windows provide meaningful comfort improvements — R-6+ versus R-2 for double-pane — and eliminate the condensation and sill icing that double-pane windows produce in severe cold. At minimum, choose double-pane with warm-edge spacers (not aluminum) and proper air-sealing installation to prevent the infiltration that drives heating costs.
