Three-layer EPC core construction wood wool boards

DRVOPOR DP3 wood wool board is made of expanded polystyrene (styrofoam) and two layers of mineralised wood wool; cementitious binders and additives bind the wood wool and the core into a compact unit. The panel surface provides high-level mechanical resistance and excellent adhesion to mortar and adhesives.


  • High-level insulation — EPS thermal conductivity: λ=0.039 W/mK
  • Good adhesion to concrete and an ideal base for plastering
  • Flame-retardant (self-extinguishing) material: B1 in compliance with DIN 4102, E in compliance with EN 13501-1
  • Neutral in combination with building materials and metals
  • Great mechanical properties
  • Easy formatting and other installation processing

Purpose, use and installation

  • Thermal insulation of facades in thick-layered rendering systems
  • Thermal insulation of basement ceilings, underpass ceilings, columns, thermal bridges etc.
  • Thermal insulation in pitched roof insulation systems — mansard roofsInstallation in the form of sheathed concrete and permanent formwork
