Description
Soudafoam FR HY Fire Rated Expanding PU Foam
Soudafoam FR HY is a high-yield, fire-rated expanding polyurethane foam designed for sealing, filling and insulating gaps in passive fire protection systems. Delivering over 25% more yield than standard Soudafoam FR, this one-component PU foam provides outstanding fire resistance, thermal insulation and acoustic performance for professional construction applications.
With rapid curing properties and expansion up to 35-40 times its original volume, Soudafoam FR HY is ideal for sealing expansion joints, service penetrations, fire-rated door and window installations, and other fire-stopping applications. The foam adheres excellently to most common construction materials without the need for primer, helping speed up installation and improve efficiency on site.
