If you’ve been researching insulation options for your Perkasie home, spray foam has probably come up more than once — and for good reason. It outperforms traditional materials in ways that matter most: tighter air sealing, higher R-values per inch, and long-lasting durability. 

But not all spray foam is the same, and the right choice depends on where it’s going and what you need it to do.

Bulldog Insulation is the team Bucks County homeowners trust for expert spray foam insulation in Perkasie, PA.

Open-Cell vs. Closed-Cell: What Perkasie Homeowners Should Know

Spray foam comes in two types, and each one serves a different purpose. Understanding the difference helps you avoid overspending — or underspending — on your project.

Open-cell spray foam is lighter, softer, and expands to fill large cavities quickly. It delivers an R-value of roughly 3.5 to 3.7 per inch, which works well for interior walls and spaces where soundproofing matters. It’s also the more budget-friendly option.

Closed-cell spray foam is denser, more rigid, and packs a much higher R-value — around 6.0 to 7.0 per inch. It doubles as a moisture barrier, making it ideal for basements, crawlspaces, and exterior-facing walls. If you want maximum energy efficiency in less thickness, closed-cell is the way to go.

A qualified installer of spray foam insulation in Perkasie, PA will evaluate your home and recommend the right type based on your specific situation — not a one-size-fits-all approach.

Where Spray Foam Makes the Biggest Difference

Spray foam’s real strength is its ability to expand into cracks, gaps, and irregular spaces that batts and loose-fill simply can’t reach.

According to the U.S. Department of Energy, spray foam creates an effective air barrier that reduces both air leakage and heat transfer. For Perkasie homes, the areas that benefit most include:

  • Attics — Seals the building envelope from above, where most heat escapes during winter.
  • Basement rim joists — A common trouble spot where cold air sneaks in at the foundation line.
  • Crawlspaces — Closed-cell foam locks out moisture and cold simultaneously.
  • Exterior walls — Fills cavities completely, eliminating gaps that traditional insulation leaves behind.

Targeting even one or two of these areas can make a noticeable difference in how your home feels — and what you pay to heat and cool it each month.
