Expanding Foam – Fire Rated – Indoor & Outdoor Use

Product Overview

This Professional Fire Rated Expanding Foam is a one-component polyurethane foam ideal for precise application with a foam gun. It provides medium-performance fire-resistant sealing for construction joints, service penetrations, door frames, and window surrounds, offering up to two hours of protection against flame, smoke, and air movement.

The foam expands approximately 1.5 to 2 times its original volume, making it perfect for smaller to medium cavities where controlled expansion is necessary. Once cured, it adheres excellently to common building materials like brick, concrete, plaster, metal, and timber.

Its formulation allows for cutting, sawing, or plastering just one hour after application, with working temperatures between +5°C and +25°C, ensuring efficient progress on job sites. The 750ml can expands to approximately 1.2 to 1.5 litres when fully cured, offering optimal yield for professionals.

The gun-grade format provides precise control, reduced waste, and cleaner application compared to hand-held variants.
