This dataset represents hard wood fibreboard production produced in the wet process as the weighted average of hard wood fibreboards produced by the members of the European Panel Federation (EPF).

Hard fibreboard, also called hardboard, is an engineered wood product in conformity with the stan-dard EN 622-1. Hard fibreboard is produced in either the wet or dry process. The wet process leaves only one smooth side while the dry processed hardboard is smooth on both sides. Hardboard is similar to medium density fibreboard, but is denser, much stronger and harder because it is made out of exploded wood fibres that have been highly compressed. Consequently, the density of hardboard is usually about 800-1040 kg/m³. Typical thickness is in a range from 2.2-4.0 mm.
It differs from MDF in that the bonding of the wood fibres usually requires no additional materials, although resin is often added. Hard fibreboard is characterised by high dimensional stability.

Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.
