M2Tech® Shaftliner is a 1" (25.4 mm) thick gypsum board with a specially formulated fire resistive noncombustible core enclosed in a heavy moisture and mold resistant, light violet colored, 100% recycled paper. M2Tech Shaftliner gypsum board is designed and engineered for use in constructing lightweight Shaftwall and Area Separation Firewall assemblies.
M2Tech Shaftliner gypsum board is UL Classified and ULC Listed in fire resistance designs and features double beveled edges for ease of installation. M2Tech Shaftliner is available in 8' (2440 mm), 10' (3050 mm), and 12' (3660 mm) lengths.
In addition to its fire resistive properties M2Tech Shaftliner gypsum board is also designed and engineered to provide added protection against mold when exposed to incidental or intermittent moisture during and after construction. When tested for mold resistance by an independent lab at the time of manufacturing, M2Tech Shaftliner achieved the best possible scores of 10 per ASTM D3273 and 0 for ASTM G21.
