Fiber Insulation Board Lines
Efficient production lines for high quality insulation board. The market for insulation materials is continuously growing. Reduction of energy consumption offers the overall most important potential for reduction of costs and emission of carbon dioxide. Insulation of buildings based on ecologically produced wood materials has gained growing interest and importance worldwide. Insulation materials made from wood fibers are preferred materials because of their excellent characteristics like heat conduction and high heat storage capacity, as well as diffusion permeability and moisture balancing capacity.
- New environment friendly production process
- On the basis of increased requirements, more strict legislation for building insulation
- Potential to produce up to 250 mm thick boards and to achieve a density range from 35 – 250 kg/m³
- Up to 1400 m³ insulation board can be produced per day requiring max. 6,5 t/h o.d. fiber as raw material
- Products:
- Flexible boards:
- Density range 40 – 100 kg/m³
- Thickness range 20 – 250 mm
- Rigid boards:
- Density range 35 – 240 kg/m³
- Thickness range 10 – 250 mm
- Plant Capacity:
- Fiber throughput 1 – 6,5 to/hr

- New ecologically friendly dry process on the basis of increased requirements, more strict legislation for building insulation and development of more efficient binders
- Potential to produce 250 mm thick boards and to achieve a density range from 35 – 250 kg/m3
- Up to 1400 m3 insulation board can be produced per day requiring max. 6,5 t/h (oven dry) wood chips as raw material
Efficient Product Ion Lines for High Quality Insulation Board
The new dry process is based on the known MDF production by using a special blending technology and the unique curing system “CSS”.
The important process steps are as follows:
- Fiber production from chips in a pressurized refiner
- Fiber drying in a flash dryer
- Blending of
- Dry fibers with MDI/PMDI (rigid insulation board) or
- Bonding-thermoplastic fibers mixed with wood fibers (flexible insulation board) Uniform blending is a most important process step with distinct influence on resin consumption and on the final board properties
- Forming machine with integrated high efficiency dissolving rolls
- Forming belt with fiber mat densification and lateral mat trimming
- Calibration and curing in the “CSS” system. Steam injection is activating the MDI resin or the bonding-thermoplastic fibers in the specially designed curing machine “CSS”. Special control loops ensure a homogeneous density profile and excellent physical properties of the insulation board as well as a minimized raw material consumption
- Raw board handling with cut to size and profiling of insulation board
Benefits of the insulation boards produced with the new technology:
- Heat conduction capacity of 0,031 W/m*K
- Pressure resistance (referring to 10 % compaction) of more than 160 kPa
- Possibility to add hydrophobizing substances or flame retardants
- Usage in special approved design concepts for the fire resistance classes F30 – F90
- Improved living comfort based on moisture balancing
The advantages of the the new Dieffenbacher wood fiber insulation board will lead to an important growth of this product.
