<p>The invention relates to wood-based form parts, which are composed of a finely-divided wood material which is mixed with a binder and hardened into the desired shape, a method for the preparation thereof and the use of the form parts. According to the invention, the binder of the form parts comprises at least partially gluten or a similar cereal-based protein product, the weight ratio between the gluten and the wood raw material being about 0.05 to 3. Preferably, the finely-divided wood material comprises wood chips, wood fibres or wood flour. According to a preferred embodiment, the form parts contain also cement and/or gypsum and possibly a foaming agent, glycerol, glycol and/or a boron-containing substance. The form parts according to the invention can be employed for preparing heat insulation boards which are easily shaped. The thermal resistance of the heat insulation boards is of the order of 0.05 to 0.08 W/m °C.</p> |
