Professional open cell spray foam insulation for general contractors and developers in Parsippany-Troy Hills and across Morris County. Certified crews. Commercial-grade materials. On your schedule.
Parsippany-Troy Hills & Morris County
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 — making it the specification of choice for interior walls, attics, and sound-sensitive multifamily and commercial spaces.
For GCs and developers working in Parsippany-Troy Hills, 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.
JB Insulation & Drywall is a certified spray foam applicator based in Oakland, NJ. We work directly with general contractors and developers — no homeowner calls, no retail jobs.

Open cell spray foam creates a continuous air barrier that dramatically reduces infiltration losses — directly improving HVAC efficiency and energy code compliance on new construction.
The open cell structure absorbs and dampens airborne sound — making it the preferred specification for multifamily party walls, floor assemblies, and commercial office interiors.
Expands to fill odd-shaped framing, penetrations, and hard-to-reach spaces that batts cannot fully cover — reducing air leakage paths that fail blower door tests.
Open cell foam is vapor-permeable, allowing moisture to dry toward the interior — an important characteristic for many New Jersey climate zone 4A assemblies.
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.
JB's certified crews work efficiently on large commercial and multifamily volumes — sequenced to your rough-in schedule so insulation never holds up the next trade.
