Knauf Frameless Encasement Solutions using Knauf Fireboard, have been specifically developed to create encasements of column and beam structural steel work. Frameless casings simply consist of Knauf Fireboard stapled to itself at abutting corners. For steelwork encased on all four sides, Knauf Fireboard is fixed at each corner directly through the material, independent of the structural steel. For partial encasements, involving wall or ceiling abutments, the encasement is fixed using lightweight Knauf Angle Sections at the abutment.
