Harrisburg Climate Recommendations
Located in the southeastern portion of Pennsylvania, Harrisburg has a humid-continental climate. This means Harrisburg and nearby cities like York, Lebanon, and Lancaster experience all four seasons, with hot, humid summers, and cold, snowy winters. Prepare for extreme fluctuations in temperature with energy-efficient glass and materials.

Low-E Protection
Keep warm in the winter by helping to reduce the heat loss from your home. Patio doors with panes of glass with Low-E help keep your home insulated, blocking out the cold and helping keep the heat in.

Diverse Climate
Prepare for bitterly cold winters and semi-humid summers with Pella® Impervia®. This strong fiberglass, for both windows and patio doors, is durable enough to help withstand extreme heat and subzero cold.

Fiberglass Patio Doors
For good insulation and protection from drafts and leaks, choose fiberglass patio doors.
