Fireproofing Contractor — ApexSeal NY NY NJ CT PA
Fireproofing
Code-compliant passive fire protection for structural steel, concrete, and building assemblies.
What Is Fireproofing?
Fireproofing is the application of fire-resistive materials to structural elements to maintain their load-bearing capacity during a fire event. Applied to steel beams, columns, decks, and concrete surfaces, fireproofing buys critical time for evacuation and limits structural collapse. ApexSeal NY is a certified fireproofing contractor serving commercial, industrial, and institutional projects across NY, NJ, and CT — delivering fully code-compliant, inspected, and documented installations.
Why Choose This Service
- Maintains structural integrity during fire events — critical for life safety
- Required by IBC and local building codes for most commercial construction
- Spray-applied fireproofing (SFRM) is fast and cost-effective for large steel areas
- Intumescent coatings provide fire protection with an architectural finish
- Fully documented with UL-listed assemblies and third-party inspection
- Extends the time available for safe evacuation and fire suppression
- Protects your investment — reduces structural repair costs after a fire event
Our Process & Approach
Code & Assembly Review
We review the structural drawings and determine the required fire-resistance ratings (1-hour, 2-hour, 3-hour, or 4-hour) for each element based on IBC occupancy and construction type.
UL Assembly Selection
We select UL-listed fireproofing assemblies that match the structural member sizes, required ratings, and aesthetic requirements of the project.
Surface Preparation
Steel surfaces are cleaned of oil, dirt, and loose mill scale. Primer compatibility is verified. Masking protects adjacent finished surfaces.
Material Application
Spray-applied fireproofing (SFRM) or intumescent coatings are applied in controlled passes to achieve the specified thickness for the required fire rating.
Thickness Verification
We perform systematic thickness measurements using calibrated pins and document results. Minimum thickness must be met at every measurement point.
Third-Party Inspection
We coordinate with the special inspector and provide all documentation — product data sheets, thickness logs, and UL assembly references — for the project record.
Applications & Project Types
Common Questions
What is the difference between SFRM and intumescent fireproofing?
Spray-applied fire-resistive material (SFRM) — commonly called "spray fireproofing" — is a cementitious or gypsum-based material applied in thick coats. It is cost-effective for concealed steel. Intumescent coatings are thin-film coatings that expand when exposed to heat, providing fire protection with a smooth, paintable finish suitable for exposed architectural steel.
What fire ratings are available?
We install assemblies rated from 1 hour to 4 hours depending on the structural element, building occupancy, and code requirements. The required rating is determined by the building code and structural engineer of record.
Is fireproofing required on all steel buildings?
Requirements depend on building height, occupancy type, and construction classification under the IBC. Most commercial steel-framed buildings require fireproofing on primary structural members. We review the code requirements for your specific project.
Can damaged fireproofing be repaired?
Yes. We perform fireproofing repairs and touch-ups on existing buildings where the material has been damaged by mechanical impact, water, or renovation work. Repairs must match the original UL assembly.
