Made In Japan Floor base underlayment insulation board


DAIKEN's insulation board is a fiberboard with a density of less than 0.35 g/cm, manufactured by forming the plant fibers of waste wood etc. produced when buildings are demolished as the raw material.
It is useful for many purposes as an underlayment or curing material for roof, wall, or floor installation.

  • Water-repellent finish prevents the floor surface from wetting and dirt even if the rain blows in.
  • Slip-proof surface finish ensures safety in building site.
