Boss 813+ Fire Stop PU Foam and Boss 333 Foam are high-performance polyurethane foams designed for fire protection, insulation, and sealing in modern construction. Developed by BOSS Products, these foams excel in static joints, fire-rated assemblies, and acoustic/thermal insulation, offering unmatched safety and durability. This blog delves into their features, applications, and benefits, making them a top choice for builders and safety professionals.

Boss 813+ Fire Stop PU Foam: Revolutionizing Fire Protection

Boss 813+ Fire Stop PU Foam is a one-component, self-expanding polyurethane foam formulated with fire-retardant properties, meeting EN 1366-4 standards for fire-resistant jointing. Available in a 750 ml aerosol can, its pink color signals high fire resistance, ideal for sealing gaps around fireproof doors, windows, and joints in walls and ceilings.



Key Features:

  • Fire-Retardant: Resists flame spread and smoke, enhancing passive fire protection.

  • High Adhesion: Bonds to concrete, drywall, masonry, and metals.

  • Fast Curing: Cures in under 60 minutes, speeding up projects.

  • Acoustic & Thermal Insulation: Blocks sound and heat, improving comfort.

Applications:

  • Installation of fireproof doors/windows.

  • Sealing static joints in high-rises.

  • Penetration seals for pipes/cables in fire-rated walls/floors.

  • Roof construction openings and acoustic baffles.

Boss 333 Foam: Versatile Construction Sealing

Boss 333 Foam, another BOSS polyurethane expanding foam, complements Boss 813+ with broader sealing uses. It’s perfect for general construction sealing, insulating gaps, and filling cavities, offering excellent adhesion and expansion.

Key Features:

  • Expanding: Fills large voids easily.

  • Non-Toxic: CFC-free, safe for indoor use.

  • Non-UV Resistant: Apply indoors or shield from sunlight.

  • Easy Application: No mixing required; install with spray gun.

Applications:

  • Filling gaps in walls, roofs, and frames.

  • Sealing service penetrations.

  • Acoustic insulation in partitions.

Why Use Boss Products?

  • Safety: Prevents fire/smoke spread, maintaining firewall integrity.

  • Efficiency: Single-sided installation saves labor.

  • Compliance: Meets building codes (e.g., International Building Code).

  • Environmental: Uses HCFC/CFC-free propellants.


Easy Maintenance and Long‑Term Durability:


Boss 813+ Fire Stop Foam and Boss 333 Foam form resilient, closed‑cell seals that resist moisture, cracking, and shrinkage over time, reducing the need for re‑sealing and maintenance in commercial and residential constructions. This durability helps maintain fire integrity and insulation performance throughout the building’s lifecycle.


Ideal for Retrofit and Renovation Projects: 


Both foams are excellent for retrofitting existing structures, such as sealing gaps around old pipes, electrical conduits, and HVAC penetrations in retrofitted offices or apartments. Their one‑component aerosol application allows quick, clean installation without dismantling walls or fixtures, making them cost‑effective solutions for upgrading fire safety in older buildings.


Compatibility with Other Fire‑Protection Materials: 


Boss 813+ Fire Stop Foam integrates seamlessly with fire collars, gypsum boards, concrete, and intumescent sealants, allowing contractors to build multi‑layered passive fire‑protection systems. Using Boss 813+ Foam alongside these materials ensures a complete fire‑stop solution that can achieve higher fire‑rating classifications (such as 1‑hour, 2‑hour, or more) in walls, floors, and partitions.
