Fibreboard - soft - without adhesives (fibreboard production - soft - without adhesives)

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. The product fibreboard soft without adhesives' is an engineered wood product. Soft fibreboard consists of up to 85% of wood fibres. Soft fibreboard without adhesives has been produced in the wet process from wood residues from sawmills (e. g. sidings) and from wood chips. In the wet process the raw material is grinded and then mixed into a mash with up to 98% water. This mash is then formed into a so-called fibre cake. After pressing most water out of the mat the fibre cake is the cut and dried in the drying channel with temperatures between 160 to 220 °C. The addition of binders is usually not required as the heating of the liquid lignin as part of the wood bonds the fibres during cooling. For special purposes (higher strength hydrophobic properties) resins or bitumen-containing agents can be added. Thicker board are produced from gluing together several standard boards. Softboard is applied for building shell like roofs walls and floors acting as thermal and acoustic insulating material. Softboard regulates moisture balance permitting fully vapour permeable construction which avoids the risk of interstitial condensation or rot without the use of membranes or vented cavities. The cut-off classification is allocatable product. The activity type is ordinary transforming activity. The reference product amount is 1.
