The Ramset BlazeBrake™ Fire Rated Expanding Foam is a high-performance sealing solution designed for construction professionals, including plumbing, electrical, and mechanical contractors. This one-component expanding polyurethane foam effectively seals construction joints and service penetrations, preventing the transfer of flames, smoke, and gases between building compartments. With a compliance standard of AS1530.4:2014, it ensures safety in fire-rated applications while providing a 50% post-expansion rate for optimal filling of gaps. Available in a pale yellow colour and packaged in a 750mL size, this foam reacts with moisture in the air to expand and fill irregular holes or cavities. Once cured, it can be easily cut, shaped, or painted to match surrounding surfaces. Additionally, it offers sound dampening properties and excellent thermal insulation while being CFC and HCFC free, making it an environmentally friendly choice for modern construction needs.
