Flexible, High-Performance Air Sealing at Scale

Open cell spray foam expands to roughly 100 times its liquid volume, filling every gap, seam, and irregular cavity in a single pass. Its open cell structure delivers an R-value of approximately R-3.8 per inch while providing an exceptional air barrier and outstanding sound attenuation β€” making it the specification of choice for interior walls, attics, and sound-sensitive multifamily and commercial spaces.

For GCs and developers working in Old Tappan, the right insulation product depends on the specific assembly, climate zone requirements, and project budget. Open cell spray foam is typically the cost-effective solution for interior applications where a vapor barrier is not required and acoustic performance matters.

What Open Cell Spray Foam Delivers

Every advantage that matters on a GC or developer project β€” performance, acoustics, schedule, and value.

Superior Air Sealing

Open cell spray foam creates a continuous air barrier that dramatically reduces infiltration losses β€” directly improving HVAC efficiency and energy code compliance on new construction.

Exceptional Sound Attenuation

The open cell structure absorbs and dampens airborne sound β€” making it the preferred specification for multifamily party walls, floor assemblies, and commercial office interiors.

Fills Irregular Cavities

Expands to fill odd-shaped framing, penetrations, and hard-to-reach spaces that batts cannot fully cover β€” reducing air leakage paths that fail blower door tests.

Vapor-Permeable β€” NJ Climate Compatible

Open cell foam is vapor-permeable, allowing moisture to dry toward the interior β€” an important characteristic for many New Jersey climate zone 4A assemblies.

Cost-Effective vs. Closed Cell

At a lower cost per board foot than closed cell, open cell spray foam delivers outstanding value for interior wall and attic applications where a vapor barrier is not required.

Fast Installation for GC Schedules

JB's certified crews work efficiently on large commercial and multifamily volumes β€” sequenced to your rough-in schedule so insulation never holds up the next trade.

Frequently Asked Questions

Answers to what GCs and developers ask most about open cell spray foam in New Jersey.

Open cell spray foam is a soft, flexible insulation product that expands roughly 100 times its liquid volume. The open cell structure allows moisture vapor to pass through while providing an exceptional air barrier β€” making it well suited to New Jersey's mixed-humid climate zone 4A assemblies.
Open cell delivers approximately R-3.8 per inch vs. up to R-6.5 per inch for closed cell. Open cell is vapor-permeable, more cost-effective per board foot, and provides superior sound attenuation. Closed cell acts as a vapor barrier and adds structural strength. The right choice depends on the assembly, code requirements, and budget β€” JB installs both.
Yes. Open cell spray foam is widely used in commercial new construction and gut renovations for its air-sealing performance and acoustic benefits. General contractors across Bergen, Passaic, and Morris County specify it for multifamily, office, and mixed-use projects.
In many interior wall and attic assemblies, yes. New Jersey follows the 2021 IECC, which sets minimum R-values and air barrier requirements by assembly type and climate zone. JB's estimating team confirms code compliance for your specific assembly during the quote process.
Yes. JB Insulation & Drywall is a commercial-focused insulation subcontractor scaled for developer and GC timelines on multifamily, commercial new construction, and large renovation projects across Bergen County. Call (201) 485-8990 or visit jb-insulation.com/contact.
