North East Pennsylvania is known for its cold and humid climate. House insulation in PA has to be designed and installed to combat not just the cold of the winters but the high humidity levels in the summer. The insulation techniques, choice of material, and building methods and codes vary drastically from, for example, Arizona. Of course, no one size fits all, but Closed Cell Spray Foam defends the house from three major problems that NEPA Homeowners have: high heating/cooling bills, excessive moisture, and rodents.
Closed-cell spray foam insulation is ideal for PA humidity and cold climates due to several key properties that enhance energy efficiency, moisture resistance, and overall building performance. Here are the primary reasons:
Moisture Resistance
Closed-cell spray foam acts as an effective vapor barrier, preventing moisture from penetrating walls, ceilings, and floors. This is crucial in high-humidity environments, where moisture can lead to mold growth, wood rot, and structural damage. Closed-cell Foam’s dense structure repels water, ensuring that even if there is a leak, the foam won’t absorb water, which helps prevent moisture-related issues.
Moisture resistance properties makes Closed Cell Spray Foam ideal for insulating masonry or block walls, as well as below grade insulation.
Insulation Performance
There is much to say about closed-cell spray foam insulation performance, starting with the high R-value (typically around 6 to 7 per inch), providing superior thermal resistance compared to other insulation materials. This helps maintain a stable indoor temperature, particularly in cold climates with substantial heating costs. Like any spray foam insulation, it provides an airtight seal, filling gaps and cracks that traditional insulation might miss. Spray Foam reduces air leakage, improving energy efficiency and comfort by minimizing drafts and cold spots.
This is also an ideal insulation for older houses with 2X4 framing where there is just “no room” to insulate properly due to shallow framing.
Structural Strength
Due to its density and rigidity, closed-cell spray foam adds structural strength to walls and roofs. This can be advantageous in areas prone to extreme weather conditions, offering additional protection against wind and other external forces.

The author explores the results of a field study and closed-cell spray Foam structural support and resilience substantiated by lab tests. https://www.sprayfoammagazine.com/foam-news/trying-to-reason-with-hurricane-season/3215
This structural strength is also the reason why Closed Cell Spray Foam keeps the critters away from your house; inadvertently, it’s also a pest barrier.
Energy Efficiency
The combination of high R-value and airtight sealing means that buildings insulated with closed-cell spray foam require less energy to heat and cool. This results in lower utility bills and a reduced carbon footprint. By preventing air infiltration and providing excellent thermal resistance, closed-cell spray foam helps maintain a consistent indoor temperature, enhancing occupant comfort.
Longevity and Durability
Closed-cell spray foam does not sag or settle over time, maintaining its insulating properties and effectiveness throughout the life of the building. This durability is particularly beneficial in challenging climates where insulation needs to perform reliably year-round. It’s also resistant to rodents and bugs, minimizing the chances of unwanted critters entering your house and getting comfortable, destroying the house from where you can’t see them.
In summary, closed-cell spray foam’s combination of moisture resistance, high insulation performance, structural strength, energy efficiency, durability, and mold prevention makes it an excellent choice for high-humidity and cold climates. These properties help protect buildings from the elements, improve energy efficiency, and enhance overall comfort and longevity.
