THE INFLUENCE OF POST-PRODUCTION MATERIALS ON LIGHTWEIGHT WOOD FIBERBOARD PARAMETERS

The aim of this study was to produce a very low-density insulation wood fibreboard, in dry technology, with the use of post-production fibres.During the tests, different amounts of post-production fibres, coming from various stages of processing such as grinding, edges cutting, cutting to the required board size, milling and disqualification of faulty boards, were added to lightweight fibreboard.The amount of possible added post-production wood fibres strongly depends on the characteristic of the fibres and particles size distribution.The parameters of the lightweight board, the most influenced by the dimensions of the fibres used, are mainly thermal conductivity and compressive strength.
