Fire ratings of 1 to 3 hours for structural steel assemblies
Preserves architectural appearance of exposed steel and timber
Expands up to 50x when heated to form insulating char barrier
Paintable — can be topcoated with any standard finish
Code-compliant with IBC, ASTM E119, and UL standards
Ideal for design-forward commercial and residential projects
A proven, methodical approach refined over 20+ years of professional installation.
We work with architects and engineers to specify the correct intumescent coating system based on fire rating requirements, substrate type, and aesthetic goals.
Structural steel is cleaned, primed, and prepared to manufacturer specifications, ensuring proper adhesion and coating performance.
Intumescent coating is applied to the specified dry film thickness using spray, brush, or roller methods — maintaining a smooth, finished appearance.
A decorative topcoat is applied to match the design intent, and we verify proper thickness and coverage for code-compliant fire protection.
Intumescent coatings are advanced fire protection finishes applied to structural steel, wood, and other building materials that expand when exposed to extreme heat, forming a thick, insulating char layer that shields the substrate from fire damage. Unlike bulky cementitious fireproofing, intumescent coatings maintain the original architectural appearance of exposed structural elements — beams, columns, trusses, and connections — while providing fire resistance ratings of 1 to 3 hours. Sky Insulation is a professional intumescent coating contractor serving Denver, Colorado, specializing in applications for commercial, industrial, and high-end residential construction. During a fire event, intumescent coatings undergo a chemical reaction that causes the thin-film coating to expand up to 50 times its original thickness, creating a dense, insulating foam barrier that dramatically slows heat transfer to the protected structural member. This passive fire protection approach is ideal for projects where exposed structural steel is an architectural feature — such as restaurants, breweries, loft-style offices, retail spaces, and modern residential designs — where traditional spray-on fireproofing (SFRM) would be aesthetically unacceptable. Our experienced intumescent coating applicators work with architects, engineers, and general contractors to specify and install the right product system for each project's fire rating requirements, substrate type, and aesthetic goals. Intumescent coatings can be topcoated with standard paint finishes, making them invisible in the final design while providing essential fire protection.
Thin-film intumescent coatings maintain the visual appearance of exposed structural steel — no bulky cementitious fireproofing to hide the design.
Intumescent coatings expand up to 50x when heated, forming a dense insulating char that protects structural members for 1–3 hours during a fire.
Our applications meet IBC, ASTM E119, and UL fire test standards — ensuring your project satisfies both the fire marshal and the architect.
Intumescent coatings can be topcoated with any standard paint finish, making fire protection invisible in the final architectural design.
Intumescent coatings are thin-film fire protection finishes applied to structural steel and other materials. When exposed to extreme heat, the coating expands (intumesces) up to 50 times its original thickness, forming a dense, insulating char layer that protects the substrate from fire damage.
Intumescent coatings can provide fire resistance ratings of 1 to 3 hours depending on the product system, application thickness, and structural assembly. The required rating is determined by building type and occupancy per the Denver Building Code and IBC.
Intumescent coatings are thin-film, paintable finishes that preserve the appearance of exposed structural steel. SFRM (Spray-Applied Fire-Resistive Material) is a thicker, cementitious material that covers the steel completely. Intumescent coatings are chosen when architectural aesthetics are important.
Yes. Intumescent coatings are designed to be topcoated with standard paint finishes. This makes the fire protection invisible in the final design, allowing exposed steel to match any color scheme or architectural vision.
Denver's thriving design scene creates strong demand for intumescent coatings in RiNo breweries, LoDo restaurants, converted warehouse offices, modern loft residences, and retail spaces where exposed structural steel is an architectural feature.
Yes. Sky Insulation works directly with architects, structural engineers, and general contractors to specify and install intumescent coating systems for commercial and residential projects throughout Denver and the Front Range.
