Closed-Cell & Open-Cell Spray Foam in Concord, NC | Concord Spray Foam Insulation
Get the exact foam density, R-value, and air barrier your framing requires—installed on schedule for Concord homeowners, remodelers, and custom builders.
Choosing the Right Spray Foam Chemistry for Every Cavity
Spray polyurethane foam (SPF) is not a one-size-fits-all product. Spraying the wrong density in the wrong building assembly wastes money or creates moisture issues. Whether you are framing a custom home in Cabarrus County, adding an in-law suite, or renovating an older Concord property down to the studs, we engineer hybrid and dedicated foam packages tailored to North Carolina Climate Zone 3A.
Our heated mobile rig carries both 0.5-lb open-cell and 2.0-lb closed-cell chemical sets. During your free site walk, we evaluate each wall, roof slope, overhang, and subfloor to recommend the highest-performing combination for your budget.
When to Use Open-Cell Spray Foam (0.5 lb/ft³)
- High-Expansion Air Sealing (R-3.7 to R-3.8/inch): Expands up to 100x its liquid volume to pack around electrical boxes, plumbing pipes, and irregular framing joints.
- Unvented Attic Roof Decks & Gable Walls: Ideal for 2x8, 2x10, and 2x12 rafters where 5.5 to 8 inches of depth delivers R-20 to R-30 at the lowest cost per R-value.
- Interior Soundproofing & Media Rooms: Soft, open cell structure deadens airborne voices, home theater bass, laundry room vibration, and highway noise.
- Clean Scarfing & Flush Stud Trimming: For open 2x4 and 2x6 walls, our crew scarfs excess foam flush with the wood studs so drywall hangers can install sheetrock cleanly.
When to Use Closed-Cell Spray Foam (2.0 lb/ft³)
- Maximum R-Value per Inch (R-6.5 to R-7.0/inch): Delivers R-14 in just 2 inches and R-21 in 3 inches—ideal for shallow framing bays and concrete block walls.
- Built-In Class II Vapor Retarder: At 1.5 inches thick, closed-cell foam stops moisture vapor movement without needing separate plastic sheeting.
- Structural Wall Racking Strength: Rigid closed-cell foam glues sheathing to framing studs, increasing wall racking strength by up to 250% against high winds.
- Cantilevered Floors, Garage Ceilings & Wet Zones: Seals carbon monoxide and car exhaust out of bonus rooms built directly above attached garages.
