Insulations have a great importance in terms of the reduction of energy consumption in buildings [1]. Hemp shive board can be seen as an alternative to such boards that are made from processed wood fibres and resins. [2] Research and practice has shown that alongside natural fibres use in textiles, they can also be used successfully as composites reinforcements, compounds of building materials, as heat and sound insulation materials, and in many other applications [3]. For example, hemp fibre boards are 2.5 times more resistant and 3 times more elastic than wood fibre boards and they are much more resistant to moisture [4]. The purpose of the work is to compare density and insulation property for board at the one amount raw material hemp shive, wood chips and mixture 50/50 hemp shive with wood chips. In RTU Institute of design technology experimental laboratory 400x400 mm size board samples are produced with cold pressing technology and as adhesive used KLEIBERIT 862.0 Urea Formaldehyde (Figure 1). The tests are performed to determine such parameters as raw material granulometric analysis, board density and thermal conductivity according to EU standard methods. References: 1. D. Mathis et.al.
