Savolit Wood Wool Boards

The composition and performance of Savolit boards makes them ideal for many different applications in building construction with their surface providing an excellent mechanical key for direct plastering or rendering. Manufactured in accordance with European Standard EN 13168.

Applications

  • External cladding of timber frame walls
  • Internal lining of timber frame walls
  • Base Board for plastered ceilings and walls
  • Internal partition walls
  • Carrier board for render
 

Composition

Savolit wood wool boards consist of long wood fibres, stabilised by chemical impregnation and bound by cement-binding agent into a compact coherent structure. The mineralisation process strongly increases the fire resistance of wood wool. The composition and performance of the boards make them ideal for many different applications in building constructions. Produced in accordance to standard EN 13168 (FIW München).

Savolit boards are manufactured from 100% FSC certified wood. FSC logo
