How Spray Foam Insulation Helps You Meet Connecticut’s Energy Code Requirements

Insulate Right: Meet CT Energy Codes with Spray Foam

When planning a new construction, addition, or renovation in Connecticut, one of the most important components is insulation—not just for comfort and energy savings, but also to comply with local building codes.

At Ortiz Spray Foam Insulation, LLC, we specialize in high-performance spray foam installations that help your project meet Connecticut’s energy standards with ease. In this post, we’ll explain how spray foam insulation supports code compliance and why it’s a smart choice for any home or construction project.

🏡 What Is Connecticut’s Energy Code?

Connecticut follows the International Energy Conservation Code (IECC) with state-specific amendments. This code sets minimum energy performance standards for building components like:

• Insulation (walls, ceilings, floors)

• Windows and doors

• Air sealing and vapor control

• HVAC and mechanical systems

  
  

If your structure doesn’t meet these requirements, you risk permit delays, added costs, or failed inspections. This is why the right insulation strategy from the start is key.

✅ How Spray Foam Helps You Stay Code-Compliant

Spray foam insulation offers several advantages over traditional materials. It combines thermal insulation, air sealing, and moisture resistance in one application—making it easier to meet and exceed code expectations.

🔹 Higher R-Values in Less Space

Spray foam provides a high R-value per inch:

• Closed-cell spray foam: ~R-6.5 to R-7 per inch

• Open-cell spray foam: ~R-3.5 to R-4 per inch

This allows you to reach the required thermal performance without building thicker walls or using extra layers of rigid foam.

🔹 Built-In Air Barrier

Connecticut code also requires homes to minimize air leakage. Spray foam naturally seals cracks, joints, and penetrations—helping meet air sealing requirements without additional sealing products or tape.

🔹 Moisture and Mold Prevention

Closed-cell spray foam doubles as a vapor barrier, preventing moisture build-up and condensation issues that can lead to code violations or failed inspections—especially in basements, rim joists, and crawlspaces.

📏 Connecticut’s Typical Insulation R-Values

Here are common R-value targets based on Connecticut’s IECC climate zone (Zone 5):

Area	Required R-Value
Exterior Walls	R-20 cavity or R-13 + R-5 continuous
Roof/Ceilings	R-49
Floors over Unconditioned	R-30
Basement Walls (conditioned)	R-15 continuous or R-19 cavity
Crawlspace Walls	R-10 continuous or R-13 cavity

With spray foam, these standards are easier to meet—and often exceeded—in a single application.

🧱 Example from the Field

In a recent home addition in Ridgefield, CT, our team installed:

• 7.5 inches of closed-cell foam in the attic for an R-value over 50

• 4.5 inches in the exterior walls for over R-30 performance

This helped the builder pass inspection quickly while also improving indoor comfort and energy efficiency.
