Foster® C.I. Wrap™ 50 Membrane is a robust and flexible vapor retarder sheet membrane. It is constructed using synthetic, rubber-modified asphalt laminated to a durable polymer film, with a treated peel-and-stick release liner for ease of application. It is suitable for use over various types of thermal insulation materials, including cellular glass, polyurethane, polyisocyanurate, polystyrene, rigid fiberglass, and others, enhancing the insulation's performance and protection against moisture and vapor ingress.

Foster® MAST-A-FAB® WHITE Reinforcing Membrane 42-24 features a synthetic fiber composition that offers enhanced elongation, recovery, and resistance to stress breakage. This membrane's leno weave design ensures fabric stability, eliminating the typical thread movement and distortion found in plain weave cloths. Importantly, it has no discernible impact on the flame spread and smoke-developed ratings of the chosen mastic or coating.

Foster® C.I. Wrap™ 30 Vapor Retarder Sheet Membrane is a flexible vapor retarder sheet membrane. It is constructed using synthetic rubber-modified asphalt laminated to a durable polymer film, featuring a treated peel-and-stick release liner for easy application. C.I. Wrap™ 30 offers the advantages of controlled film thickness, efficient and labor-saving application, elastomeric properties that accommodate insulation system expansion and contraction, self-healing capabilities, and a strong bond to both the substrate and sheet overlaps.

Foster® 95-55 Sealant is a one-component, butyl-based sealant primarily employed as a vapor barrier sealant within the joints of cellular glass, polyisocyanurate (PIR), urethane, and phenolic foam board stock insulations. This sealant remains non-skinning and does not dry within the joint, which permits thermal cycling through a broad spectrum of temperatures without issue.

Foster® ElastiSeal™ Butyl Rubber Sealant 95-88 is a single-component sealant with solvent release based on butyl. This sealant is specially engineered to deliver outstanding exterior weathering capabilities. It is user-friendly, facilitating easy application and tooling while also demonstrating exceptional adhesion to various clean surfaces.

Foster® Elastolar® Sealant 95-44 is a flexible, fire-resistant sealant formulated with butyl elastomer. This vapor barrier sealant is intended for sealing joints in insulation (excluding polystyrene foam), metal, and masonry applications where maintaining a water-tight and air-tight seal is essential. It is suitable for use as a joint sealant in low-velocity duct air-conditioning systems and is particularly effective in sealing the laps of metal jacketing to prevent moisture ingress.

Foster® 96-04 Butyl Flashing Tape is a pre-formed, double-sided tape that comes in rolls with a release liner. This tape is extruded and non-hardening, consisting of a solvent-free, 100% solids gap-filling sealant with excellent tack. It is designed to create a weather-resistant and watertight seal while providing strong adhesion to various substrates, including metal, wood, glass, rubber, and masonry.

Foster® Drion® Contact Cement 85-75 is a fast-setting, water-resistant adhesive for sealing the laps of vapor barrier jackets and is also used for bonding materials to a variety of surfaces in applications where immediate adhesion and high initial adhesive strength are required.

Foster® H.I. Mastic® 90-07 is a durable protective weather coating specifically designed for outdoor use over thermal insulation when an economical breathing mastic is needed. This asphalt emulsion product is crack-resistant, even at critical right-angle bends during curing. It exhibits exceptional weathering stability, resulting in a firm and durable surface that withstands acids, alkalies, abrasion, and typical outdoor industrial conditions.

Foster® Cryolar™ 1K Vapor Stop Sealant 90-61 is a ready-to-use, one-component vapor stop sealant specifically designed for use in cryogenic applications. It is formulated with select synthetic rubbers to create an elastomeric vapor barrier film capable of spanning the temperature ranges encountered in cryogenic processes, including LNG, ethylene, and ammonia production. This sealant is suitable for application to various insulation materials like PUR and PIR foam, cellular glass, and other rigid insulations. It can be used in conjunction with aluminum, steel, and masonry construction materials.

Foster® Cryogenic Vapor Stop Sealant 90-66 is a two-part elastomeric sealant designed for cryogenic applications as a vapor stop sealant. It is suitable for use with various insulation materials such as polyurethane foam, polyisocyanurate (PIR) foam, cellular glass, fibrous glass, aerogel, and other rigid and flexible insulations. This sealant is compatible with aluminum, stainless steel, metals, wood, and masonry construction materials.

Foster® Spark-Fas® Adhesive 85-20™ is a rapid-setting, non-flammable, fire-resistant synthetic elastomer adhesive. It is specifically utilized for bonding duct wrap, fibrous glass, or mineral wool insulations with densities of up to 6 lbs. to galvanized steel and aluminum air conditioning or hot air ducts. This adhesive is chosen when a fire-resistive dry film is necessary. It contains non-flammable chlorinated solvents, eliminating the risk of explosions and fires during the application process.

Foster® 83-13HM ZP Hot Melt Adhesive is a high-performance, pressure-sensitive hot melt adhesive (PSA) designed for specific applications in attaching facing materials to various types of thermal insulation in pipe covering and facing projects. This adhesive is compatible with a range of facing materials, including ASJ, FSK, Saran, polyester, and other paper and aluminum foil laminate facings, when used in conjunction with fiberglass, PIR, PUR, phenolic, polystyrene, and cellular glass insulations.

Foster® Stic-Safe® Adhesive 85-15™ is a fast-setting synthetic elastomer adhesive tailored for affixing fibrous glass insulation (up to 6 lbs.) to sheet metal surfaces like galvanized steel or aluminum found in air-conditioning ducts, hot air ducts, and metal buildings. Foster® 85-15™ unique consistency facilitates quick and effortless brushing onto metal ducts and various other surfaces. Additionally, it serves as an effective adhesive for lap-sealing vapor barrier jackets.

Foster® Multi-Purpose Adhesive 97-15 is a high-tack, quick-setting, water-based adhesive specifically designed for various insulation applications. It is commonly used for bonding polystyrene foam insulations (both extruded and beadboard), fibrous glass insulation, and PIR/polyurethane board stock insulations to a range of porous substrates, including concrete, masonry, gypsum board, and more.
