In commercial construction, sustainability is no longer a feature — it’s a requirement. From New York City’s Local Law 97 to national energy-code upgrades, every new or renovated structure must perform smarter, cleaner, and more efficiently than ever before. One of the most effective ways to achieve those goals happens inside the walls and ceilings — through spray-applied insulation.
At Wohl Diversified Services, we’ve seen first-hand how advanced spray-foam systems are transforming building envelopes. Using next-generation closed-cell formulations such as NCFI InsulBloc HFO, our teams deliver airtight, high-R-value insulation that helps clients meet modern energy standards while reducing material waste and environmental impact.
1. The Energy Imperative
Commercial buildings account for nearly 40 percent of global energy consumption. Much of that energy loss comes from air leaks and poorly insulated structures. As design teams push for net-zero targets, insulation is no longer a hidden trade — it’s a core sustainability strategy.
Spray-applied insulation offers a continuous, gap-free seal that traditional batts and boards can’t match. When properly applied by trained professionals, closed-cell foam forms an air, vapor, and moisture barrier in one application — dramatically improving long-term performance and occupant comfort.
2. The Science Behind Closed-Cell Foam
Closed-cell spray polyurethane foam (SPF) differs from open-cell systems in density and structure. Each cell in the foam is completely enclosed, trapping gas that enhances insulation value while adding structural rigidity.
Key technical advantages include:
– Superior R-Value: Up to R-7 per inch, providing higher performance in less thickness.
– Moisture Resistance: Creates a vapor barrier that helps prevent condensation and mold.
– Structural Strength: Adds lateral rigidity to walls, roofs, and ceilings.
– Air Tightness: Eliminates the micro-leaks responsible for major energy loss.
At Wohl, we use HFO-blown formulations — the latest generation of environmentally responsible blowing agents that replace older, high-GWP chemicals. These systems combine performance with a reduced carbon footprint, meeting today’s toughest environmental standards.
3. Sustainability Through Smarter Materials
Green building is as much about what you use as how you install it. Spray-applied insulation supports sustainable construction in several ways:
– Reduced Waste: Precisely applied on-site, minimizing off-cut material.
– Low VOC Content: Modern foams emit virtually no harmful gases after curing.
– Energy Efficiency: Lower heating and cooling loads for decades.
– LEED Contributions: Qualifies under multiple categories including Energy & Atmosphere, Indoor Environmental Quality, and Materials & Resources.
Wohl’s field teams are trained to document coverage and thickness for code and LEED compliance — giving architects and owners verifiable data for certification.
4. Performance Meets Practicality
Unlike rigid insulation boards that require mechanical fastening and cutting around every obstacle, spray-applied foam conforms to complex geometries — from mechanical chases to curved roof decks. This versatility shortens installation time, reduces labor, and delivers a tighter building envelope.
Common applications include:
– Roof decks and parapets
– Curtain-wall perimeters
– Below-grade foundation walls
– Mechanical penthouses and plenum spaces
Every application is field-verified for adhesion, continuity, and thickness before covering, ensuring long-term performance and peace of mind.
5. Case in Point: Sustainable Performance in New York City
From modern corporate offices to historic renovations, Wohl has implemented high-efficiency insulation strategies that balance sustainability with schedule and budget.
One recent example: a large-scale adaptive-reuse project in Manhattan, where the design team needed to upgrade thermal performance without disturbing existing finishes. Our crews applied closed-cell foam directly to the underside of the roof deck, delivering a seamless thermal barrier that exceeded local energy-code requirements — all while keeping the project on schedule.
6. The Wohl Approach: Precision and Accountability
Spray-foam insulation requires the same discipline as any specialty system — and that’s where Wohl’s experience stands out. Every Wohl insulation project includes:
– Certified applicators trained in manufacturer protocols
– On-site quality control with daily reports
– Coordination with other trades to ensure safe sequencing
– Documentation for energy and environmental compliance
This precision ensures your building not only meets today’s sustainability benchmarks but performs efficiently for decades to come.
7. Building the Future, Responsibly
Energy performance, comfort, and environmental stewardship are now inseparable from quality construction. As a fourth-generation New York contractor, Wohl Diversified Services remains committed to leading this evolution — helping owners, architects, and developers build green from the inside out.
Whether you’re pursuing LEED certification, complying with Local Law 97, or simply aiming for a better-performing building, Wohl delivers solutions that protect both structures and the planet.
