Foster® 95-44™ Elastolar® Sealant is a fire resistive, flexible butyl elastomer-based vapor barrier sealant. It is designed for sealing joints in insulation (except polystyrene foam), metal, and masonry wherever maintenance of a water tight and air tight seal is required. It can be used as a joint sealant in low velocity duct air-conditioning systems. It is ideal for sealing the laps of aluminum jacketing to prevent the entrance of moisture.
ELASTOLAR Sealant meets NFPA 90A and 90B 25/50 requirements. WATER VAPOR TRANSMISSION RATE (ASTM E 96) The water vapor transmission through 1 in. of impermeable insulation in 12 x 18 in. blocks with 1/8 in. joints of ELASTOLAR Sealant is too small to measure.
