Abstract
The invention relates to wood fiber insulating material boards and mats, in which the wood fibers and the binder fibers are aligned three-dimensionally. The fleece of wood fibers and binder fibers can alternatively have synthetic resin granules scattered on it. Likewise, a woven fabric or a film can be applied to one or both sides. The product obtained in this way is heated in a heating/cooling oven, calibrated and/or compacted to the desired final thickness.
