Why Hire a Professional Insulation Company in Dunwoody
Code Compliance from Start to Finish
A Professional Insulation Company in Dunwoody provides full code-compliant installation tailored to local zoning and state energy requirements. These include:
- Air sealing and vapor barrier standards
- R-value minimums for walls, attics, and crawlspaces

| Closed-Cell Spray Foam | 6.5 | Yes (walls, roofs, crawlspaces) | Excellent | Excellent | Exterior walls, basements |
| Open-Cell Spray Foam | 3.7 | Limited (attics only) | Very Good | Moderate | Attics, interior walls |
| Fiberglass Batts | 3.2 | Yes (if vapor barrier added) | Poor | Low | Walls with air barrier |
| Cellulose Blow-In | 3.5 | Yes (attics) | Moderate | Moderate | Attics |
Technical Specs for Spray Foam Systems
| Specification | Closed-Cell Foam | Open-Cell Foam |
| R-Value (per inch) | 6.0 – 7.0 | 3.5 – 3.9 |
| Water Resistance | High | Low |
| Sound Insulation | Medium | High |
| Vapor Barrier | Yes | No |
| Building Code Approved | Yes (all zones) | Attics only |

| Flammability Rating (ASTM E84) | Class 1 | Class 1 |
Bonus Tip: Closed-cell foam is the go-to for homes in humid or flood-prone parts of Dunwoody due to its vapor resistance.
Market Facts: Georgia & National Context
- In 2024, Georgia updated its Energy Code to require higher R-values in many renovation scenarios, increasing demand for energy-conscious insulation solutions
- Nationwide, 83% of building inspectors surveyed cited spray foam insulation as one of the most frequently failed areas in renovation inspections—mostly due to poor installation or lack of proper fire-rated barriers
Things to Consider Before Making a Decision
1. Local Building Code Expertise
Choose local insulation teams familiar with Dunwoody’s municipal requirements. Look for specialists who have worked with the local permitting office.
2. Product Certification & Safety
Request documentation showing that the foam insulation brand is a trusted spray foam brand approved under ICC-ES or ASTM standards.
3. Crew Credentials
Ensure you’re hiring reliable spray foam professionals—not generalists. Certified installers are required for code-verified applications.
4. Type of Renovation
Retrofit vs. new build insulation requires different techniques. A Professional Insulation Company will audit your home to identify best-fit foam insulation solutions.
5. Energy Goals
Discuss your performance expectations. Are you aiming for soundproofing, humidity control, or low utility bills? Only home insulation experts can guide based on outcomes—not just product specs.
Bonus Tip: Insist on a blower door test before and after installation to verify air-sealing effectiveness.

How long does spray foam insulation last?
Closed-cell foam can last over 30 years with no degradation, provided it’s installed properly.

FAQ
What’s the most code-compliant insulation type for Dunwoody homes?
Closed-cell spray foam is the most compliant due to high R-value and moisture resistance.
How do I verify a company is code-compliant?
Check their licensing, request past permit approvals, and ask about training in Georgia’s 2024 Energy Code.
