FireDefender FS is used for stiles and rails around the perimeter of doors, between the mineral core and the decorative wood or high-pressure laminate edges. It has excellent screw withdrawal characteristics and is also used as internal blocking material to allow hardware to be screwed to the door.
FS is made from gypsum, organic fibers, fibreglass and inert binders. In addition to its excellent performance in fire doors, FS can be used to make fire rated door frames. These can be veneered to match exactly the faces of the door and surrounding woodwork or cabinetry.
