Closed-Cell vs Open-Cell Foam:
What's the Difference
Closed-Cell Spray Foam
Dense. Durable. Moisture-Resistant.
Closed-cell spray foam creates a rigid, high-density insulation layer that delivers exceptional energy efficiency, moisture protection, and even structural reinforcement. It forms an airtight and watertight seal, making it ideal for areas where air leaks, humidity, or durability are concerns such as basements, crawl spaces, and exterior walls.
With a high R-value (Ranging from R-7-8.2 per inch), it performs extremely well in tight spaces. It also resists mold and water intrusion, adds strength to walls, and lasts for years.
Best for:
-
Crawl spaces
-
Basements
-
Exterior walls
-
Commercial buildings
-
Metal buildings and pole barns
-
Garages and workshops
-
Roof Rafters/Ceilings
Open-Cell Spray Foam
Lightweight. Flexible. Air-Tight.
Open-cell spray foam is a softer, low-density insulation that expands significantly making it perfect for filling hard-to-reach spaces and irregular cavities. It’s highly effective for sound dampening, air sealing, and energy savings in interior spaces, while also offering a more budget-friendly option than closed-cell foam.
Because it allows controlled breathability, open-cell foam is ideal for areas that don’t need a vapor barrier. It expands up to 100 times its original size, ensuring thorough coverage and reduced drafts in walls, ceilings, and attic spaces.
Best for:
-
Attics
-
Interior walls
-
Ceilings
-
Soundproofing projects
-
Renovations or retrofits where flexibility is needed
Our Installation Process
At JB Spray Foam Insulation, we follow a precise, code-compliant process to ensure your batt insulation performs at its highest potential.
Step-by-Step:
1. On-Site Evaluation & Estimate
Every project begins with an on-site walkthrough where we assess framing, identify key areas for insulation, and verify conditions such as moisture, obstructions, or accessibility. We then provide a clear, itemized estimate based on square footage, material selection, and local code requirements. No guesswork — just honest, informed recommendations.
2. Expert Installation
Our trained installers apply each system using the proper method for the material and application. Whether installing spray foam, batt, blown-in insulation, or specialty systems, we focus on complete coverage, correct thickness, and proper sealing to ensure optimal performance. Every installation is completed according to manufacturer specifications and industry best practices.
3. Quality Assurance
Once installation is complete, we perform a detailed quality check of all treated areas. This includes verifying coverage, depth, adhesion or fit, and overall consistency. We follow manufacturer guidelines and energy code standards to ensure long-term performance, comfort, and inspection readiness
4. Final Prep for Inspection
Before wrapping up, our crew ensures the site is clean, organized, and prepared for the next stage whether it’s drywall or city code sign-off. We take pride in delivering work that meets inspection standards the first time, minimizing delays for builders and homeowners.
