Expanding Foam – Fire Rated – Indoor & Outdoor Use

Product Overview

This Professional Fire Rated Expanding Foam Gun Grade offers a high-performance fire-resistant seal for construction joints, service penetrations, door frames, and window surrounds, forming a durable barrier against fire, smoke, and air movement. The foam expands up to 50 times its original volume, filling irregular or wide cavities that conventional fillers cannot reach. It adheres excellently to building materials such as brick, concrete, plaster, metal, and timber. Its formulation allows cutting, sawing, or plastering just one hour after application, enhancing efficiency on job sites. The 750ml size provides optimal yield, expanding to approximately 40 litres when fully cured. The gun-grade format ensures precise control, reduced waste, and cleaner application.
