Safing Mineral Wool

Quick Overview

4 inch (102mm) thick x 24”(61cm) x 48"(122cm) and 24 ft 2 (2.23 m 2 ) per polyethylene heat shrink package. Other thickness(s) 2" through 5" are available by special order. NOTE: Lesser product thickness may be used providing the installed thickness of insulation measured between the cold side of wall and the fire side of the wall is a minimum 4”(102mm) when a 3 hour rating is desired. Heavier densities of DELTA ® BOARD will provide equal or better fire stopping performance when installed along with the safing specifications.
