Fire-resistance ratings of 1 to 4 hours for structural assemblies
Cementitious and fiber-based SFRM products
Compliant with Denver Building Code, IBC, and NFPA standards
Experienced crews for tight commercial construction schedules
Coordination with GCs and building inspectors
High-rise, mid-rise, and industrial applications
A proven, methodical approach refined over 20+ years of professional installation.
We review project specifications, fire rating requirements, and structural drawings to determine the correct SFRM product, thickness, and application method.
Structural steel surfaces are cleaned of oil, dirt, and loose scale to ensure proper SFRM adhesion. Adjacent surfaces are protected from overspray.
Fire-resistive material is spray-applied to the specified thickness on beams, columns, connections, and deck assemblies using calibrated spray equipment.
We perform thickness testing per ASTM standards, prepare inspection documentation, and coordinate with building inspectors for code compliance sign-off.
Spray-applied fire-resistive material (SFRM) is the most widely used passive fire protection system in commercial construction. Applied directly to structural steel beams, columns, trusses, and metal deck assemblies, SFRM creates a thermal barrier that insulates structural members from the extreme temperatures generated during a fire, delaying or preventing structural failure and protecting building occupants. Sky Insulation provides professional SFRM application for commercial, industrial, and multi-family construction projects throughout Denver and the Front Range. Our certified crews apply cementitious and fiber-based SFRM products to achieve fire-resistance ratings of 1 to 4 hours, depending on the assembly type and code requirements. We work with the leading SFRM manufacturers and follow all application specifications to ensure consistent thickness, density, and bond strength. Denver's commercial construction market demands fireproofing contractors who can deliver on tight schedules without compromising quality. Sky Insulation's experienced crews coordinate closely with general contractors to sequence SFRM application efficiently, minimize trade conflicts, and ensure every application passes building inspection on the first visit.
SFRM is the industry-standard fireproofing method trusted on thousands of commercial buildings — providing reliable fire-resistance ratings backed by UL and ASTM testing.
Our applications meet all Denver Building Code, IBC, and NFPA requirements, with proper documentation for building inspections.
20+ years of commercial fireproofing experience means efficient application, minimal rework, and reliable schedule adherence.
We work closely with general contractors to sequence SFRM application efficiently within the overall construction schedule.
We apply both cementitious (gypsum-based) and mineral fiber SFRM products. The product selection depends on the fire rating required, the structural assembly type, and whether the application will be exposed or concealed.
SFRM thickness varies based on the fire-resistance rating required (1 to 4 hours) and the structural member type (beam, column, deck). Typical thicknesses range from 3/8 inch to 2+ inches. We follow manufacturer specifications for each assembly.
We perform thickness testing throughout the application using pin gauges per ASTM E605 standards. We also verify bond strength and density to ensure the SFRM will perform as specified during a fire event.
Yes. We provide SFRM patching and repair services for areas damaged by subsequent trades during construction. Timely patching ensures fire protection integrity is maintained through project completion.
