Shield HD doors are designed to limit the transmission of heat from a fire.
With a high density wool core, the doors have excellent heat retardation properties, which prevent the temperature of unexposed areas from exceeding 250F, thus allowing sufficient time for people to safely evacuate the area. Suitable for areas where impact resistance is important. The mineral wool infill also increases the acoustic capability of the doors allowing them to reach an acoustic rating up to 42 db.
