Reed board


Lasting thermal insulation – reed board
Three in one – siding, insulation and plaster base

Advantages of reed board in brief

  • higher heat retention
  • reduction in cold bridges
  • ideal interior climate
  • natural product in an authentic form
  • most environmentally friendly insulation


Technical indicators of reed board:

  • Density: 150 kg/m³
  • Heat conductivity: λ=0.055 W/mK
  • Diffusion resistance factor: μ=6.5
  • Heat capacity: c=1.200 MJ/kg
  • Construction material category according to DIN 4102: B2


Smart siding

Reed board consists of natural reeds bound by wire into boards. Reed board is good for both siding and insulation. The high flexibility along the length of the reed dampens sound and thus does away with the need for bulky soundproofing panels. This is why reed board is the best siding material for frame houses and roof construction.

Comfortable insulation

Use of reed board in interior finishing when accompanied by clay plaster or on the exterior with lime plaster or siding ensure lasting reliability. Even a thin layer of reed board on the inside wall is enough to let the surface of the wall reach a very pleasant temperature fast. A consistent indoor temperature produces a sense of cosiness. The optimum indoor temperature and moisture level is ensured through a combination of reed board and clay plaster.

Good for the environment

Reed board ensures a good interior climate and responds to changes in the weather patterns. Artificial insulation materials use CO2 but reed board is carbon neutral, and has the highest sequestration value of natural insulation boards. It takes 83 times less energy to make a reed board than a polystyrene insulation panel.


Reed board is made of natural reeds. An annual reed plant is used as the material. The reeds used for the purpose undergo critical selection to ensure that the reed has superlative workability and hardiness.

Reed mat

A rendering base made of reed is used to reinforce clay and lime plaster. There are around 70 reeds per metre, and they are tied to one another with galvanised wire. Its rough surface and flexibility make the reed mat a valuable base for plaster.
