US150 Firestop Brick
US150 Firestop Brick is a medium density, flexible polyurethane foam designed to firestop large openings containing various penetrants. Once exposed to fire US150 is highly intumescent, this expansion provides a tight seal against the passage of flame, smoke and toxic gases.
US150 can be easily cut to fit on site so penetrants can be easily added, changed or removed and the US150 Bricks can be reused to restore the firestop rating. This makes US150 ideal for use with data and communication cabling or control cabling and cable trays.
US150 can be installed from one side allowing openings with limited access to be effectively firestopped. US150 pillows require no curing so are not limited by installation temperature like sealants. offering a window install window.
