The mineral wool bag is a fire-retarding product that takes seconds to install and provides hours of fire resistance. As a result of the astm-e-84-70 test (surface-burning characteristics of building materials), the bag has been rated as a Class "A" building material. In the astm-e-119 test for fire endurance, the bag did not allow fire to pass through the opening for 64 minutes at 1750 degreesF. The device is used to fill open areas around conduits, pipes, and cables to prevent the transmission of fire, heat, and smoke. The wool bag measures 12 x 12 x 11 inches and weighs 20 ounces. Packaging is 30 bags per box.
