01 Systems

Fire wrap systems.

Brunco Insulation Ltd provides specialized fire-wrap systems designed to protect critical building services while meeting the demanding fire-resistance requirements of modern residential, commercial, and industrial construction.

Since the introduction and widespread adoption of fire-wrap technologies in the early 2000s, these systems have become an essential component in passive fire protection strategies across the mechanical insulation and construction industries. Developed through advanced testing and engineering by leading manufacturers such as 3M, Unifrax, CL4, and Morgan Thermal Ceramics, fire-wrap systems offer efficient, space-saving alternatives to traditional fire-rated shaft enclosures and assemblies.

With nearly 30 years of industry expertise, Brunco Insulation delivers professionally engineered fire-wrap solutions for multi-unit residential, multi-tower condominium, rental, commercial, and institutional developments. Our services include the installation of fire-rated systems for HVAC ductwork, kitchen grease ducts, dryer exhaust systems, pressurization ducts, piping systems, electrical raceways, structural steel components, and other critical life-safety applications where maintaining fire compartment integrity is essential.

Our experienced team provides complete consultation, system review, manufacturer coordination, and engineering support to ensure every installation meets applicable building code, UL/ULC listings, and project-specific performance requirements. Utilizing high-temperature ceramic fiber and advanced endothermic fire protection materials, we provide tested and certified assemblies ranging from 1-hour to 4-hour fire-resistance ratings, helping developers, contractors, and consultants achieve compliant, efficient, and reliable passive fire protection solutions.
