Who We Are
We're Building Scientists First. Installers Second.
Most contractors quote first and ask questions later. We start with a professional building envelope assessment — measuring actual R-values, identifying air infiltration paths, locating moisture-drive condensation zones, and reviewing your project against the NYC Energy Conservation Code (NYCECC).
That diagnosis tells us exactly what system is required: closed-cell vs. open-cell, required inch thickness, vapor retarder classification, and fire-stopping requirements under NYC Building Code Chapter 7. You receive a written scope, not just a number on a page.

Why Choose Spray Foam Insulation?
No other insulating material seals your home from air and moisture intrusion, saves on utility bills, strengthens your home, and protects your family's health like spray foam.
Specialist Services
Engineering the Right Solution for Every Building
Every engagement starts with a diagnostic assessment. We identify your specific thermal, moisture, and code compliance issues — then prescribe exactly the right system to solve them permanently.
Closed-Cell Spray Foam
Achieves R-6.5 to R-7 per inch — the highest thermal resistance available. Creates a rigid, vapor-impermeable envelope that stops air infiltration, moisture migration, and thermal bridging in a single application.
- R-6.5–R-7 per inch
- Vapor & air barrier in one
- Structural rigidity added
- Required by NYCECC for many assemblies
Ideal For
Basements, roofs, exterior walls, crawl spaces
Typical Cost
$1.50–$3.00 / sq ft
Open-Cell Spray Foam
R-3.7 per inch with superior acoustic dampening. Expands to fill every stud cavity and penetration, eliminating drafts, condensation on interior surfaces, and uneven temperatures in sound-sensitive spaces.
- R-3.7 per inch
- Best-in-class sound reduction
- Fills every gap & cavity
- Cost-effective interior solution
Ideal For
Interior walls, ceilings, between floors
Typical Cost
$0.75–$1.50 / sq ft
Fireproofing & Fire Stopping
Intumescent coatings and UL-rated assemblies engineered to meet NYC Building Code Chapter 7 requirements. We work directly with DOB inspectors and deliver all documentation needed for commercial certificates of occupancy.
- UL-listed intumescent coatings
- DOB Chapter 7 compliant
- Full inspection documentation
- 1–4 hour fire-resistance ratings
Ideal For
Commercial, mixed-use, new construction
Typical Cost

Attic & Roof Assembly
The attic accounts for 25–40% of a building's heat loss. We calculate your R-value deficit against NYCECC targets, then prescribe the right system — spray foam, blown-in, or hybrid — to close the gap permanently.
- R-value deficit assessment
- NYCECC compliance planning
- Air sealing + insulation
- Roof deck & rafter options
Ideal For
Residential homes, brownstones, flat roofs
Typical Cost
$1.00–$2.50 / sq ft
Commercial & Multi-Family
Building envelope consulting for warehouses, mixed-use, co-ops, condos, and new construction. We model thermal performance, identify code compliance gaps, and deliver installations that pass DOB energy inspections the first time.
- Thermal performance modeling
- DOB energy compliance sign-off
- Co-op, condo & warehouse experience
- Full project documentation
Ideal For
Warehouses, condos, mixed-use, new builds
Typical Cost
Custom quote — scope-based
Moisture & Condensation Control
Condensation on walls, pipes, and ceilings is a building science failure — not a cosmetic one. We perform dew-point analysis to pinpoint the exact source, then apply closed-cell foam to shift the condensation plane outside the envelope.
- Dew-point analysis included
- Mold risk elimination
- Permanent moisture plane shift
- Post-remediation verification
Ideal For
Basements, cold walls, pipe chases, roofs
Typical Cost
