Production of wood fibre boards (MDF/HDF) Fibreboard usually has a homogeneous structure which is finer than that of particleboard. They can therefore be processed similarly to solid wood i.e. it is possible for example to mill or profile them. A distinction is mainly made between MDF (medium density fibreboard) and HDF (high density ...

Common formats. Wood fibre insulation can be designed to deliver a range of functions through varying to some degree both manufacturing technique and board ingredients. Flexible insulation. Application: Friction mounted between studs / rafters. Thermal conductivity: circa 0.038 W/mK. Density: circa 50 kg/m3.
As I’ve said previously there are two different ways of manufacturing wood fibre boards. Now the first process is wet processing and essentially you take chipped timber – so all waste timber – you grind it up and then you boil it up with water and a few other chemicals designed to break down the timber into the fibres.
The 'Wet' process. 1 - Chips and shavings from typically spruce and fir are retrieved as waste from the manufacture of other timber products. 4 - The mix is pumped into a forming box as a continuous fibre mat. 5 - Around half the water is removed through pressing and vacuum pumping. 6 - The board material is dried in an air drier.
