Three-layer construction wood wool boards with core of super NEO

The wood wool board DRVONEO DN3 is made of expanded polystyrene with improved insulating properties, type Neo super and two layers of mineralised wood wool; cement binder and additives unite wood wool and the core into a compact unit. The surface provides high mechanical resistance and exceptional grip of the boards for mortar and adhesives.


  • extraordinary insulation properties – thermal conductivity for Neo super: λ=0,032 W
  • good adhesion to concrete and the ideal surface for plastering
  • difficult inflammable (self extinguishing) material: B1 after DIN 4102, E- per EN 13501-1
  • neutrality in combination with building materials and metals
  • insulating core protected from the effects of the sun at installation
  • very good mechanical properties
  • easy formatting and other processing at installation

Purpose, use and installation

  • thermal insulation of facades in systems with thick-layered plaster
  • thermal and sound insulation of inner walls
  • thermal insulation of basement ceilings, ceilings above subways, pillars, thermal bridges,…
  • thermal insulation in insulation systems of pitched-slope roofs – mansards
  • installation by way of coated concrete and lost formwork
