Adhesive Guru AG510 not only functions as a deterrent to airborne sound transmission but also exhibits an intumescent property. In the event of a fire, the material expands, enabling the sealant to sustain a firestop penetration seal for up to 4 hours when penetrants are exposed to fire. Specifically crafted to control the propagation of fire, smoke, and noxious gases, its efficacy persists both before and after exposure to fire, provided it is installed in adherence to a listed through-penetration or fire-resistive joint assembly system.
