Fire Block Extreme

Fire Block Extreme PRO is a fire blocking foam sealant designed to work in the most extreme conditions, for ambient temperatures of -4°F to 100°F. Although Fire Block Extreme is ideal for all high and low humidity applications, Fire Block 113 is recommended in desert climates. Although it is not approved as a fire stop, Fire Block Extreme is a certified draft stopping and fire blocking product. It is orange in colour for easy inspection recognition. Fire Block Extreme uses a minimal shrinking technology to ensure an airtight seal while providing industry-leading yield, and is safe to be used around windows and doors. It offers minimal post-expansion for small gap filling while also being capable of filling gaps of up to three inches. It offers premium adhesion to most construction materials, including: wood, metal, masonry, glass, vinyl, and some plastics.
