“…By including hemp shives and longitudinally milled wood chips in thermal insulation materials with PCM, the thermal inertia of the building can be increased without enlarging the mass of the building [19]. To provide the same heat capacity as a 10 mm thick PCM layer, a 110 mm thick brick wall is required [20][21][22].…”

The growing availability and decreasing cost of microencapsulated phase change materials (PCMs) present an opportunity to develop innovative insulation materials for latent heat energy storage. By integrating PCMs with traditional insulation materials, it is possible to enhance the thermal capacity of a building by up to 2.5-times, virtually without increasing the building’s mass. To improve buildings’ indoor structural performance, as well as improving their energy performance, microencapsulated PCMs are integrated into wallboards. The integration of microencapsulated PCMs into the wallboard solves the PCM leakage problem and assures a good bond with the building materials to achieve better structural performance. The novelty of this research is the application of encapsulated phase change material dispersion and technology for its incorporation into the structure of hemp shives and longitudinally milled wood chip-based insulation boards, using cold pressing technology to reduce the energy consumption of board production. As a result, low-density insulation boards for indoor application were produced by varying their structure and the amount of phase change materials in the range of 5% to 15% by board mass. The obtained board prototypes can be used as microclimate and thermoregulation elements of interiors, as well as functional aesthetic elements of interior design.

Summary Renewable biomaterials are in the spotlight as a potential solution to increasing global greenhouse gas emissions. The construction industry contributes up to 40% of greenhouse gas emissions, with building materials responsible for a major portion. Research on high‐performance materials with small carbon footprints has been steadily progressing. Wood is a sustainable building material with a high carbon fixation. Wood can be divided into the hard core and outer bark, both of which are very useful as building materials. In this study, a phase change material (PCM) was applied using vacuum impregnation to compensate for the poor thermal performance of wood. The thermal energy storage capacity of wood can be enhanced by applying aPCM, which has excellent latent heat/heat storage performance. The difference in the structural and chemical compositions of the core and bark of wood also has a significant influence onPCM impregnation. The thermal performance of shape‐stabilized PCMs (SSPCMs) was evaluated by comparing the hierarchical structures and components of wood (core and bark). The PCM loading performance was verified by impregnation and surface/morphological property conversion analyses. When the porous structure of wood is filled with the PCM, its surface properties change from hydrophilic to hydrophobic. This was analyzed by contact angle measurements. The SSPCM with cork showed a 49% efficiency compared with the n‐octadecane, which indicates an outstanding performance compared with other biomaterial‐based PCM composites.

“…Nearly all types of woodworking processes generate significant amounts of by-products and residues [ 1 ]. This material is used for a determined period and then subsequently recycled as wood shavings [ 2 ], disposed of as residues from primary wood processing, e.g., sawdust, trimming residues, wood pieces, chips and bark [ 3 , 4 ], or combined with other materials to form composites [ 5 ]. These by-products and leftovers result from the processing of the logs and, added to the branches, trunks, and roots that remain in the forest, represent a significantly higher volume than those of the wood product obtained [ 6 ].…”

“…Abu-Jdayil et al (2019) [8] analyzed the renewable thermal building insulation materials including wood shavings. The thermal properties of phase-changing materials (able to release, absorb or store sufficient energy at phase transition to provide useful heat/cooling) combined with wood shavings were studied by [5]. The thermal insulation performance of concrete was improved by adding wood shavings while decreasing its compressive strength [9][10][11][12].…”

Oversized Planer Shavings for the Core Layer of Lightweight Particleboard

Planer shavings (PS) are side-products generated during the processing of solid wood, typically used for heating, packaging, or insulation purposes. PS has been used for decades in particleboard manufacture, particularly in the core layer. The aim of this research is to investigate the use of PS with a length over 4 mm in low-density one-layer particleboard manufacturing with a thickness of 10 mm, as an option to reduce the raw material demand for wood-based panels. Correlations towards the mechanical properties of the particleboards, fabricated at a density of 475 kg/m3, could be drawn by analyzing the effects of different urea-formaldehyde adhesive contents (6%, 9%, and 12%). Two methods of adhesive application (pouring and spraying) and two types of blending of PS with adhesive (plowshare mixer and drum mixer) were investigated, with the aim that PS will have controlled resin application. The difference between the adhesive application methods was examined by analyzing the mechanical properties as an internal bond, modulus of rupture, and modulus of elasticity as well as indirectly by visualizing the adhesive distribution by adding a green pigment to the adhesive before application. PS demonstrated reduced bending properties in comparison with the EN 312 standard requirements of particleboards for internal use in dry conditions (type P2), due to the low density. The internal bond strength in the case of the particleboard without pigment application (up to 0.5 N/mm2) was higher compared to the P2 requirements (0.4 N/mm2), and significantly lower (0.15 N/mm2) in combination with the pigment (2.5% based on the board weight, compared to 0.1%, specific for such industry applications), but still superior to the values of the reference panel manufactured with wood particles.
