Knauf Gypsum Boards comply fully with the requirements of ASTM1396/1396M. Knauf has the following boards under certification with Intertek in various sizes. Product description from :
Knauf Gypsum Board (GW-R) - Knauf GW-R Gypsum Boards are gypsum based wallboards whose front and back surfaces, and long edges, are sandwiched in a board liner. Knauf GW-R boards are used for cladding walls and ceilings that are constructed on metal grids and wooden frames: for furring, partitions and ceilings, prefab building units and for dry lining using dot and dab of a gypsum based bonder.
Knauf Moisture Resistant Gypsum Board (GB-WR) - Knauf GB-WR Moisture Resistant Gypsum Boards are gypsum boards whose gypsum core is additionally hydrophobized against absorption of moisture. Their application is similar to the Knauf GW-R Boards. However MR boards are primarily used for bathrooms and kitchens in private housing and offices.
Knauf Type X Fire Resistant Gypsum Board (GW-TX) - Knauf GW-TX Type X Fire Resistant Gypsum Boards are gypsum based wallboards whose core is reinforced with fiber glass for purpose of fire resistance. Knauf GW-TX boards are preferred in shaft wall installations, furrings, partitions, suspended ceilings and prefab units were fire protection requirements are needed.
Knauf Type X Fire Resistant IMPACT Gypsum Board (GW-TX IMPACT) - Knauf GW-TX Type X IMPACT Fire Resistant Gypsum Boards are gypsum based wallboards whose core is reinforced with fiber glass for purpose of fire resistance. Knauf GW-TX IMPACT boards are preferred in shaft wall installations, furrings, partitions, suspended ceilings and prefab units were fire protection requirements are needed.
Knauf Type X Fire and Moisture Resistant Gypsum Board (GB-WRTX) – Knauf GB-WRTX Type X Fire & Moisture Resistant Gypsum Boards are fire resistant boards with a reinforced fiber glass core whose that is additionally hydrophobized against absorption of moisture. Their application areas are similar to the Knauf FR Boards. However FM boards are primarily used for bathrooms and kitchens in private housing and offices. Knauf GB-WRTX Type X boards can be used as a substitute for GW-TX boards when specified in designs.
Knauf GB-WR Mold Type X Gypsum Board (GB-WR MOLD) – Knauf Moisture and Mold resistant Gypsum board feature unique technology that combines moisture and mold resistance and is specially engineered to provide enhanced protection against mold growth. This board is Type X approved for enhanced Fire resistance. Knauf GB-WR Mold boards can be used as a substitute for GW-TX boards when specified in designs.
Knauf Type X Fire Resistant Gypsum Coreboard (DH-H1) – Knauf Coreboards are 1” (25.4mm) thick type X Special Fire Resistant gypsum wallboards developed specifically to be used in conjunction with Knauf Shaftwall Systems where access from one side is restricted, given a high fire performance while being simple to construct.
