Product information

Product names

  • fermacell®flooring elements
  • fermacell®gypsum fibre boards

Product description

The product consists of two homogenous fibre gypsum boards that are glued together with an offset of 50 mm to produce a rabbeted edge. They are produced in two different thicknesses (20 mm and 25 mm) and the boards are 1 500 mm long × 500 mm wide, with a total surface area of 0.75 m2. The connection between each panel is completed with fermacell® Floor Glue. The panels are placed in succession in a floating installation.
