Metacaulk® 1000 is a single component, general purpose fire rated sealant and smoke seal for construction joints and through penetrations. Metacaulk® 1000 is a water based, extremely intumescent, non-sag caulking grade sealant that is easy to apply. It cures to an elastomeric seal that is suitable where dynamic movement is expected. In the event of a fire, Metacaulk® 1000 will prevent the spread of flames, smoke, hot gases and water through joint openings and through penetrations. Metacaulk® 1000 systems are rated for 1, 2, 3 and 4 hr in accordance with the ASTM E814 (UL 1479), ASTM E1966 (UL 2079) and CAN/ULC-S115 test standards.
