Production of wood-fiber insulation boards using a dry-manufacturing process

Siempelkamp Maschinen- und Anlagenbau developed a new method for producing wood-fiber insulation boards using a dry-manufacturing process. These boards are used to insulate against heat, cold, and impact sound. The new process allows the production of boards with a thickness of 20 (0.8 in) to 240 mm (0.8 ft).

Advantages of the new process

Energy savings of about 30 % per ton of finished product compared to the traditional wet-manufacturing process are, at today’s energy costs, a true advantage.

For the first time, the production of thicker boards (up to 240 mm or 0.8 ft) is possible. In the past, such thickness could only be achieved by gluing boards together.

The board density is adjustable and can be set from 80 kg/m³ to 220 kg/m³. Different densities result in different application areas for the boards (e.g., insulation against impact sound, heat, or cold).

The board length can be adjusted according to the application. The new process is designed for a maximum board width of 2,500 mm (8.2 ft).

The capacity of the line is impressive: 1,320 m³ per day can be achieved for boards with a thickness of 240 mm (0.8 ft) and a density of 80 kg/m³. The capacity decreases with a thinner board and a higher board density.
