This product is heat-resistant, capable of withstanding temperatures up to 240 degrees Fahrenheit. It meets ASTM E 84 standards for smoke spread and flame development. The foam is ready to use, creating a tack-free surface in about five minutes.
This fireblock foam is designed to restrict the passage of flames and combustion by-products, effectively sealing any gaps in concealed spaces like floors, ceilings, and walls.
