Intumescent Fireproofing
Intumescent fireproofing is a type of passive fire protection that uses a special coating which expands when exposed to heat, creating an insulating char layer that protects structural steel. Unlike traditional spray fireproofing, intumescent coatings provide fire protection while maintaining an aesthetically pleasing finish — making them ideal for exposed structural steel in architectural applications.
Northeast Fireproofing is certified to apply intumescent coatings from major manufacturers. Our teams are experienced in both shop-applied and field-applied systems, and we work closely with project architects and engineers to meet both the fire rating and aesthetic requirements of each project.
Intumescent Fireproofing Services in NJ, PA, DE & MD
Northeast Fireproofing specializes in intumescent fireproofing coatings for exposed structural steel across New Jersey, Pennsylvania, Delaware, and Maryland. Our intumescent coating services are ideal for architecturally exposed structural steel (AESS) where the aesthetics of the finished product are as important as fire protection performance.
Unlike traditional spray fireproofing, intumescent coatings are applied as a thin paint-like finish that expands dramatically when exposed to heat, forming a protective char layer around the steel. This makes intumescent the preferred choice for lobbies, atriums, parking structures, and any application where structural steel remains visible in the completed building.
Applications & Markets We Serve
Our intumescent fireproofing crews serve a broad range of project types across the Philadelphia tri-state region and beyond. We have applied intumescent coatings on corporate headquarters, healthcare facilities, educational institutions, sports venues, mixed-use developments, and transit infrastructure throughout New Jersey, the Delaware Valley, and metropolitan Philadelphia.
We are approved applicators of CAFCO SprayFilm, A/D Firefilm and Hilti Fire Finish intumescent systems, and work closely with architects, steel fabricators, and general contractors to coordinate shop-applied vs. field-applied coating strategies based on project logistics and schedule requirements.
Quality You Can See
- Architecturally Acceptable Finish: We apply intumescent coatings to achieve smooth, paintable finishes suitable for exposed locations.
- Shop or Field Application: We coordinate with steel fabricators for shop application or mobilize our own crews for field application — whichever works best for your schedule.
- UL-Listed Systems: All coatings we apply are UL-listed and code-compliant for the required fire resistance rating.
- Manufacturer-Certified: Northeast Fireproofing is an approved applicator for all major intumescent coating manufacturers serving the NJ/PA/DE/MD market.
From new construction projects in Philadelphia and New Jersey to renovation projects in Delaware and Maryland, our intumescent fireproofing crews deliver consistent quality and reliable scheduling. Request a quote from our project management team today.
