Pennsylvania experiences a humid continental climate with cold, snowy winters and warm, humid summers, with meaningfully harsher winters in the Pocono and Allegheny regions than in Philadelphia and the southeast corridor.

For attic insulation projects specifically, this means timing and material selection are key factors in both cost and quality.
