Wood as a renewable foam insulation | Good News
Today is the issue of energy saving in the foreground for each client. The federal government has tightened the requirements for climate protection with new buildings again until October 2013. Therefore walls and roofs must be well insulated, so that as little fzom costly heating energy dissipated to the outside air.
One uses this preferred hardboard or polystyrene, both use as a raw material petroleum. This material is favorable to manufacture and has good insulation properties, but of environmentally friendly materials one can not speak here. Quite apart from this, as this material has a negative effect on the Raunklima.
Scientists at the Fraunhofer Institute for Wood Research WKI in Braunschweig take a different approach. They have developed a novel process fzom in which can be made from wood particles a foam which can be used just like the standard plastic foams. Explains Prof. Volker Thole from WKI: "Our wood foam can be used just like traditional plastic foams, but is a wholly owned natural product made from renewable resources". In the preparation of the foam timber, the wood is first milled fzom into fine particles. This creates a slimy slurry, is introduced into the gas, which leads to the formation of the foam. In conclusion to the foam to harden. A further preparation method is based on chemical processes. For this purpose, fzom explains Prof. Thole: "You can think as similar to baking if the dough to rise in the oven and becomes solid." In both cases, the result is a very lightweight base material, the more easily fzom either into sheets or deformable foam mats can be processed.
Are already known insulating fzom material made of wood such as fleeces or wood shavings, but they have the disadvantage fzom that they easily fibers and not as form-stable as plastic material. Developed at the WKI Wood foam does not have these disadvantages. "We have our foam products according to the standards that apply to insulation materials, and analyzed with regard to the thermal insulation, mechanical and hydric - get promising results thus question the moisture properties," says Prof. Thole.
Meanwhile, you are at the WKI about to find out which types of wood are best suited. Furthermore, they are working fzom on the manufacturing processes in order to adapt to industrial requirements. In the future, you can see at the Fraunhofer Institute the use of wood foam not only in the insulation, but also in the packaging, so that the wood could replace polystyrene foam as a packaging material in the foreseeable future.
