SAUERLAND BOARD is produced using the extrusion press system which is the first continuous production method for wooden materials.
1. It is the only way to produce tubular particle boards :
2. The particles are positioned vertically to the surface of the board
3. Homogeneous material for the whole thickness of the board
The vertical position of the chips leads to the following technical characteristics:
1. Thickness swelling
Advantages for door manufacturing :
2. Compression resistance
3. Bending Strength
Extruded boards are used as cores or middle layers. They are always crossbanded on both sides with thin particle board, hardboard, MDF or plywood. In all cases the bending strength is obtained by crossbanding.
Consequences for the sound insulation:
Apart from the mass the bending strenght is the decisive factor for the sound insulation.
low bending strength ⇒ high sound insulation
The low bending strength of the SAUERLANDBOARD is very advantageous for a high sound insulation.
