Wood wool not only has excellent properties as an insulating material, but its rough appearance can also be very decorative

Wood wool boards or boards are made up mainly of wood, cement and water. It is a material used in wall and ceiling cladding, and its characteristics include fire resistance, acoustic and thermal insulation properties.

Species of conifers in the form of fine threads are especially used for the manufacture of wood wool. Firs, pines, poplars, etc. Along with wood, cement is used as the main mineral element, although depending on its use it can be combined with other materials, such as lime, rock wool, polyethylene …

The result is a rough, whitish surface. Thanks to increasingly sophisticated production processes, this roughness can practically disappear. In addition, the application of pigments allows you to find wood wool in a multitude of colors.

Like plates, it can be found in low, medium or high density. This will depend on the pressure or amount of material used per cubic meter.


  • Soundproofing. It is one of the characteristics most demanded by those who use wood wool. It has a very high noise absorption index. It is often used in installations with high noise levels, such as parking lots or industries, to acoustically isolate them from offices or residential areas.
  • Thermal insulation. It is possible to thermally insulate the house or building and considerably reduce the costs of heating or air conditioning. This also makes wood wool a quick payback material.
  • Fire resistance. It is a highly regarded material in the construction areas for its proven fire resistance and low reaction. This contributes to improving the strength of the structures that wood wool normally covers.
  • Moisture resistance. The material cannot and does not absorb moisture, so its use may also be possible in environments such as bathrooms.
  • Durability. It is a tough material, although it does not reach the level of an OSB or oriented chip board. In terms of useful life it must be the same as that of the building.
  • Ecological Material. If the wood used comes from responsible farms, we would be facing an ecological material of renewable origin and with low environmental impact. It is 100% recyclable.

Uses of wood wool boards

  • Traditionally, the main use of wood wool was to upholstery inside walls and ceilings to thermally and acoustically insulate a building.
  • Today this use is still maintained, but more and more is seen. This raw look is demanded by architects and interior designers.
