Knauf FireWin - protipožární tmel FPA Akryl

Knauf FPA fire-retardant acrylic is a fire-retardant, one-component and partially flexible acrylic mass, designed for fire sealing. Under the influence of high temperature, the mass swells, ensuring an effective seal against fire, smoke and gas. Acrylic hardens under the influence of weather conditions, but remains flexible to some extent in order to ensure the mobility of the joint. It swells under fire exposure to form a fireproof seal.
