Foster® 81-84™ Cellular Glass and Urethane Adhesive/Sealant is a two-component, high strength thermosetting urethane adhesive containing non-flammable solvents. It is designed to bond various types of low temperature insulation to themselves and to metal and masonry substrates. After curing, it forms a strong, yet flexible bond capable of withstanding thermal shock and mechanical impact.

Foster® 30-45™ N Foamseal® Sealant is a gray vapor barrier sealant designed for use with rigid thermal insultation including polystyrene foam. It remains flexible and tough in joints and will not shrink or crack during repeated cycles of high and low temperatures.

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.

Foster® 95-50™ Flextra® Sealant is a one-component, elastomer-based product used as a vapor barrier sealant in the joints of cellular glass and urethane foam board stock insulations. It remains soft and flexible, preventing damage to the insulation due to thermal cycling through a wide range of temperatures.
