“…The bark protects the layer of cambium of the tree mitigating also the harmful effect of fire (Bauer et al, 2010, Wang -Wangen 2011. A number of products come from tree bark like absorbers and raw material for fertilizers, however, the need for higher valued products is always the ultimate goal for each material (Naundorf et al, 2004).…”

Two disparate waste materials were mixed to identify the likelihood of constructing insulation boards. Treebark and Hemp (cannabis) residues were combined in different proportions and with two dissimilar typesof glue. The thermal conductivity (λ) for all boards was measured. Diverse methods of processing the finalboards demonstrated altered thermal properties based also on the different density (low and medium).The results have validated the possibility of exploiting local waste materials to produce an eco-friendly,low priced insulation product with competitive (λ) compared to the market products. All materials werecollected within a small range to the laboratory (< 100 km). The energy requirements and the carbonfootprint of these boards were kept low compared to traditional chemical insulation materials.

“…They concluded that E. globulus bark fibers could be incorporated beneficially (in low amounts) in cementitious materials. In parallel, the significantly higher amount of inorganic compounds of bark, compared to wood material, 55 contributes to a fire‐retardant character, 56 which constitutes a crucial characteristic for the future utilization of bark in structural applications. Semple and Evans 57 highlighted that when bark is present in wood‐cement composites, the compatibility of Melaleuca uncinata increases compared with composites without bark; in contrast, the bark of Eucalyptus loxophleba strongly inhibits cement hydration, depending on the chemical composition of the bark, which varies greatly among different wood species.…”

This review gives an overview of recent advances in research on the role of tree bark material in bark-cement bio-composites, and their potential as building insulation materials. Suberin and other bark extractives seem to be of great importance for the insulation properties of such composites. Bark is a readily available, biological raw material with unique properties and it has revealed promising results as a bio-insulation material, either alone or in mixtures with different matrices (cement, lime, resins, polymers, etc.). The thermal, mechanical, acoustic, and hygroscopic properties of these bark-insulating composites depend on several factors, primarily the type of tree bark, the density and mechanical strength of the bark, the density of the boards produced, and the ratio of bark material to the binder material used in the board production (cement, lime, resins, polymers, etc.). The size of granules and the thickness of the board produced seem to be factors with a lower impact on the properties of the bark-cement composites. A low proportion of bark fibers or particles (0.5-1%) in bark-cement composites has proven highly beneficial to their mechanical and thermal properties and ensures higher workability of the mixture. Different modification treatments of bark material should be investigated, with the aim of decreasing the bark extractives content, to improving the cement setting, decreasing the unstable hemicellulose components and their hygroscopic nature, improving the bark particles' durability in alkaline environments, and upgrading their adherence properties. As the demand for alternative, sustainable structural materials keeps rising, the cement-bark composites will undoubtedly keep attracting the attention of the scientific and industrial world.

Larch (Larix decidua) bark insulation board: interactions of particle orientation, physical–mechanical and thermal properties

The current trend for sustainable utilisation of limited resources is stimulating the scientific research for previously neglected raw materials that could also be used for new value added products. Bark, which is a natural insulation material of trees, could be used as technical insulation material. This paper focuses on the effects of particle orientation in light larch (Larix decidua) bark insulation boards on their physical-mechanical and thermal properties. The experimental design is based on the variation of the particle orientation (orthogonal or parallel to the panel plane) and the board density (200-500 kg/ m 3 ). The mechanical properties, water absorption, thickness swelling and thermal conductivity of the boards were tested. The results showed a significant influence of the particle orientation and the density on the measured properties of the bark panels. This implies that the bark particle orientation is an important factor when producing insulation panels with specific characteristics. Suggestions for efficient use of bark particleboard are given.
