Why Builders Use Spray Foam for High-Performance Homes

As homebuyers become more focused on energy efficiency, comfort, and sustainability, the demand for high-performance homes is rising fast. And when it comes to meeting those standards, more and more builders are turning to spray foam insulation as their go-to solution.

At Custom Insulation Company, Inc., we work closely with homebuilders throughout the region to deliver insulation solutions that go beyond code—and spray foam consistently comes out on top.

What Is a High-Performance Home?

A high-performance home is designed and built to:

• Maximize energy efficiency
• Reduce environmental impact
• Enhance indoor comfort and air quality
• Deliver long-term cost savings to homeowners

To meet those goals, every part of the home’s envelope needs to work in harmony—and insulation is a critical component.

Why Builders Prefer Spray Foam Insulation

1. Unmatched Air Sealing

Unlike fiberglass or cellulose, spray foam expands on application, sealing even the smallest gaps and cracks. This minimizes air leakage, which is one of the leading causes of energy loss in homes.

Result: A tighter building envelope with better control over indoor temperatures and moisture.

2. Superior R-Value per Inch

Closed-cell spray foam has a high R-value (around R-6.0 to R-7.0 per inch), offering better thermal resistance than traditional insulation. This allows builders to meet or exceed energy codes with less material and wall thickness.

3. Structural Strength

Closed-cell spray foam adds rigidity to walls and roofing systems, making homes more resilient against wind and weather—especially beneficial in storm-prone regions.

4. Moisture Barrier

Spray foam resists moisture, helping prevent mold and mildew. This is especially important in basements, crawl spaces, and attics where condensation and humidity can lead to costly damage.

5. Fewer Callbacks

Builders appreciate fewer homeowner complaints related to drafts, cold spots, or uneven temperatures. Spray foam delivers consistent performance year-round, reducing the likelihood of post-construction issues.

Designed for Code Compliance and Beyond

With building codes becoming stricter—especially in energy-efficiency and air-sealing requirements—spray foam helps builders stay compliant while adding long-term value to the home. It’s an investment that pays off in both performance and buyer satisfaction.
