Intumescent Firestop Material
RectorSeal Joint Strip is a flexible, highly intumescent firestop material used in concrete/masonry control floors and wall joints up to 2 inches wide. It forms a strong char that prevents the passage of flame, smoke, and hot gases between control joints. Use with plastic pipe penetrations. Ideal for stadium construction, tilt up panels, curtain wall panels and all concrete and masonry construction joint applications where a fire rated control joint is required. Approved with any UL listed sealant. For more information, visit metacaulk.com/index.php/metacaulk-firestop-joint-strip.
