Expanding Foam – Fire Rated – Indoor & Outdoor Use

Product Overview

Our High-Performance Fire Rated Expanding Foam is a versatile polyurethane foam designed for precise application directly from the can. It provides a robust fire-resistant seal for construction joints, service penetrations, door frames, and window surrounds, forming a durable barrier against fire, smoke, and air movement.

This foam expands up to 50 times its original volume, effectively filling irregular or wide cavities that conventional fillers cannot reach. Once cured, it adheres excellently to most building materials, including brick, concrete, plaster, metal, and timber. Its formulation supports efficient job site progress, as it allows for cutting, sawing, or plastering just one hour after application. The 750ml size yields approximately 40 liters of cured foam, ideal for professional use.

Features & Benefits
