3M Fire Block Foam for Ready-to-Use Foam-in-Place, 12 fl oz Can

The Fireblock foam is a durable polyurethane-based product, heat resistant up to 240°F (115°C), that has been tested to ASTM E84 (modified) as a Type V Residential Fireblock. This ready-to-use foam (no mixing required) expands up to 200% in volume upon dispensing, enabling it to quickly and effectively seal openings, thereby inhibiting air circulation and helping to reduce air infiltration, making it a valuable Draftstop solution.

Designed for industrial and occupational use only, this product is not intended for consumer sale or use. Its unique volume-expanding properties allow it to expand significantly once applied, ensuring a thorough and reliable seal that can help prevent the spread of fire and smoke.

The heat-resistant nature of the polyurethane foam formulation means it can withstand elevated temperatures without compromising its integrity, making it a suitable choice for applications where fire safety is a primary concern.

By undergoing testing to the ASTM E84 (modified) standard for a Type V Residential Fireblock, this Fireblock foam has demonstrated its ability to meet the necessary performance criteria for use in residential construction projects, where it can play a crucial role in compartmentalizing spaces and inhibiting the spread of fire and smoke.

The ready-to-use format of the Fireblock foam eliminates the need for any mixing or preparation, allowing for quick and efficient application on the job site. This convenience factor can help streamline the installation process and reduce the overall time required to complete the task.

Overall, the Fireblock foam's combination of durable heat resistance, volume-expanding capabilities, and fire-inhibiting properties make it a valuable tool for industrial and occupational users in need of a reliable solution for sealing openings and preventing the spread of fire and smoke.
