Attic & Crawl Space Insulation Services in Jonesboro, AR
Up to 40% of a home’s conditioned air escapes through an uninsulated attic, while damp crawl spaces account for nearly half of the air you breathe on the first floor. At Jonesboro Spray Foam Insulation, we provide specialized attic and crawl space insulation solutions that lock in comfort, lower monthly power bills, and eliminate indoor air quality hazards across Northeast Arkansas.
By applying high-density spray polyurethane foam, we seal the top and bottom of your building envelope—stopping thermal loss and moisture intrusion at the source.
Our Attic & Crawl Space Insulation Services
1. Attic Spray Foam Insulation
Traditional blown-in cellulose or fiberglass batts sit on the attic floor, leaving the roof deck exposed to blistering Arkansas summer heat. We apply spray foam directly to the underside of your roof deck, transforming your attic into a clean, semi-conditioned space.
- Roof Deck Sealing: Blocks heat before it enters the attic space, keeping ductwork cool.
- Air Leakage Control: Seals top plates, wire penetrations, and ceiling fixture gaps.
- HVAC Efficiency: Reduces the strain on attic-housed HVAC units and ductwork.
2. Crawl Space Encapsulation & Insulation
Open vents and dirt floors in crawl spaces allow outdoor humidity to seep under your home, creating ideal conditions for wood rot, mold, and pest infestations. Our complete crawl space encapsulation and spray foam service turns damp under-floor spaces into dry, energy-efficient foundations.
- Vapor Barrier Installation: Heavy-duty membrane covers dirt floors to block soil moisture.
- Rim Joist & Foundation Wall Sealing: Closed-cell foam seals perimeter walls and rim joists against drafts and moisture.
- Floor Temperature Control: Keeps wood and tile floors warm during cold winters.
3. Subfloor & Rim Joist Insulation
Drafty floors and cold spots along exterior walls are usually caused by unsealed rim joists. We apply closed-cell spray foam along the foundation band and subflooring to eliminate cold air infiltration and structural dampness.
4. Old Insulation Removal & Attic Prep
Before applying fresh spray foam, degraded, pest-damaged, or moisture-laden fiberglass batts must be safely removed. Our crew handles complete vacuum extraction, surface sanitation, and air-sealing prep work.
