What to Consider When Re-Insulating Your Existing Building

Re-insulating an existing structure is more than just adding more batts or blowing in extra material. To achieve lasting energy savings, enhanced comfort, and improved indoor air quality, you need a strategic approach tailored to your building’s unique needs. Here’s what to evaluate before you start—and how Fresh Coast Foam can guide you every step of the way.

1. Assess Your Current Insulation & Air Sealing

• Insulation Type & Condition
  Identify whether you’re dealing with fiberglass batts, blown-in cellulose, or aging spray foam—and check for sagging, gaps, or moisture damage.

• Air Leakage Points
  Drafts around windows, doors, recessed lighting, and wall/ceiling penetrations can undermine even the best insulation. A blower-door test or infrared scan helps pinpoint trouble spots.

• Vapor & Moisture Barriers
  Buildings without proper vapor control can trap humidity in wall cavities, leading to mold and rot. Ensure your insulation strategy includes continuous air and vapor sealing.
  
  
  

Tip: Fresh Coast Foam’s certified team performs a full diagnostic—combining blower-door testing and thermal imaging—to map existing insulation performance and leakage paths.

2. Define Your R-Value Goals

• Climate Zone Requirements
  West Michigan’s cold winters and humid summers call for higher R-values than milder regions. Current code might require R-49 in attics, R-20 or R-13+5 in walls, and R-10 at rim joists.

• Space Constraints
  In retrofit situations, cavity depth may be limited. High-performance options like closed-cell spray foam (R-6 to R-7 per inch) or open-cell foam (R-3.5 per inch) can deliver superior thermal resistance in thinner profiles.

• Cost vs. Payback
  Calculate projected energy savings against installation costs. While premium materials may have a higher upfront price, their longevity and airtight seal often yield faster returns.
  
  
  

Tip: We help you model annual heating and cooling savings so you can choose the optimal R-value for your budget and comfort targets.

3. Choose the Right Insulation Material

Consider performance factors—R-value per inch, moisture control, air sealing, and long-term durability—to pick the material that aligns with your building’s demands.

4. Address Structural & Moisture Challenges

• Rot, Mold & Pests
  Before insulating, repair any water leaks, replace rotten framing, and treat for pests. Sealing voids with spray foam can then maintain a dry, pest-resistant barrier.

• Thermal Bridging
  Uninsulated studs or floor joists conduct heat and create cold spots. A continuous spray foam layer or exterior rigid insulation can break thermal bridges for a fully sealed envelope.

• Ventilation Needs
  Airtight buildings require controlled ventilation—such as ERVs/HRVs or ridge vents—to manage humidity and ensure fresh air without energy waste.
  
  
  

Tip: Fresh Coast Foam integrates moisture management and structural reinforcement into our spray foam installs, so your re-insulation project boosts durability as well as insulation value.

5. Plan for Minimal Disruption & Cleanliness

• Worksite Containment
  Retrofit spray foam and loose-fill installations can generate dust or overspray. Proper tarping, negative-pressure containment, and post-work cleaning protect your belongings.

• Timeline Coordination
  Align insulation work with other trades (electricians, drywall installers) to avoid re-work and keep your project on schedule.
  
  
  

Tip: Our crews arrive with fully equipped rigs and go-to containment systems, finishing most residential re-insulations in a single day with zero mess left behind.

6. Verify & Maintain Performance

• Quality Assurance Testing
  After installation, blower-door tests, thermal imaging, and spot-checks confirm airtightness and uniform coverage.

• Future Inspection & Upkeep
  While high-quality insulation lasts for decades, it’s wise to inspect attics and crawl spaces periodically for water leaks or settling.

Tip: Fresh Coast Foam provides post-installation testing and documentation, plus guidance on maintaining peak performance throughout your building’s life cycle.
