Core Energy & Comfort Capabilities

Roof Insulation Installation

Complete thermal envelope build to R-38 / R-49 North Carolina building code standards, paired with air-tight top-plate sealing to eliminate energy loss.

Roof Insulation Replacement

Safe vacuum extraction of compressed, rodent-contaminated, or water-damaged fiberglass, followed by attic deck sanitization and brand-new virgin fill.

Attic Insulation

High-density blown-in virgin fiberglass or stabilized cellulose providing a continuous, seamless thermal blanket across all ceiling joist cavities.

Spray Foam Roof Insulation

Applying high-R closed-cell or open-cell polyurethane foam directly to the underside of roof rafters, converting hot attics into conditioned storage spaces.

Cool Roof Installation

Installing high-SRI (Solar Reflectance Index) architectural shingles and bright-white membranes that reflect solar heat back into the atmosphere.

Roof Insulation Repair

Patching localized insulation voids around recessed can lights, bathroom exhaust ducts, and installing R-50 insulated zipper tents over attic access stairs.

Our 6-Step Energy-Efficiency Insulation Protocol

  1. Step 1 — Pre-Insulation Energy Audit & Thermal Infrared Scan: We scan ceiling planes with infrared thermal imaging cameras to pinpoint exact heat-leak zones, measuring current insulation depth.
  2. Step 2 — Comprehensive Air-Sealing (Top Plates & Chases): Before blowing new insulation, expanding polyurethane foam seals all wire penetrations, plumbing vent chases, recessed can lights, and top plates.
  3. Step 3 — Soffit Baffle Installation at Every Rafter Bay: Rigid foam vent chutes are stapled into every eave rafter bay so blown insulation never blocks incoming convective airflow.
  4. Step 4 — Old Contaminated Insulation Extraction (If Required): Commercial negative-pressure vacuums safely remove wet, animal-damaged, or compressed insulation directly into outdoor disposal bags.
  5. Step 5 — Pneumatic High-Density Blowing to Code Depth (R-49): Using calibrated depth markers, we blow virgin fiberglass or cellulose to an exact depth of 14 to 18 inches for uniform R-value coverage.
  6. Step 6 — Insulated Attic Hatch Box & Final Thermal Camera Sign-Off: We install an R-50 insulated zipper tent over attic access stairs and verify complete thermal coverage with infrared imaging.

Frequently Asked Questions

1. How much attic insulation do I need for a home in Cary, North Carolina (R-38 vs R-49)?

Under the North Carolina State Building Energy Conservation Code (IECC Climate Zone 4A), residential attics require a minimum of R-38 (approx 12-14 inches), with R-49 (approx 16-18 inches) strongly recommended for optimal savings.

2. How much can new roof and attic insulation lower my Duke Energy electricity bill in summer?

Proper air-sealing paired with R-49 insulation routinely reduces monthly Duke Energy air conditioning bills by $40 to $90+ per month during peak summer months.

3. What is the difference between blown-in fiberglass, cellulose, and spray foam insulation?

Fiberglass is fireproof and does not settle; cellulose offers high R-value from recycled fibers; spray foam creates an airtight vapor seal directly against rafters.

4. Can you install spray foam insulation directly to the underside of roof sheathing?

Yes. Applying spray foam directly to roof rafters creates an unvented conditioned attic, ideal for homes with HVAC ductwork located in the attic.

5. Why is air sealing top plates more important than simply blowing in more inches of insulation?

Insulation slows conductive heat transfer, but moving air leaks through unsealed ceiling gaps. Sealing bypasses with foam stops the 'stack effect'.

6. What are the signs of old, compressed attic insulation that needs replacement?

Warning signs include hot upstairs bedrooms, visible depth under 6 inches, dark dust filtration near eave vents, and rodent nesting odor.

7. What is a Cool Roof in Wake County?

A Cool Roof uses reflective shingles or white membranes that reflect up to 85% of solar heat, lowering attic temperatures and extending shingle life.

8. Does new roof insulation qualify for federal energy tax credits (Section 25C)?

Yes! Cary homeowners can claim a federal tax credit of 30% of insulation material costs (up to $1,200 per year) under the Inflation Reduction Act.
