How Allentown's Climate Affects Siding Replacement
Allentown's extreme winters demand insulated siding with meaningful R-value. Insulated vinyl (R-3 to R-6) reduces thermal bridging through wall studs and prevents the freeze-thaw moisture cycling that degrades standard siding. Proper moisture barrier installation beneath the siding is critical — inadequate house wrap allows water infiltration that freezes and expands inside the wall cavity.
