Abstract This study investigates the potential for enhancing the thermal performance of external walls insulation in warmer climates through the combination of phase change materials (PCMs) and bio-based materials, specifically hemp wool and wood wool. Experimental tests using the heat flow method (HFM), and numerical simulations with ANSYS Fluent software were conducted to assess the dynamic thermal distribution and fluid-mechanical aspects of phase change materials (PCMs) within composite walls. The results demonstrate a notable reduction in peak indoor temperatures, achieving a 58% reduction with hemp wool with a close 40% reduction with wood wool when combined More >

Abstract Magnesite-bonded wood wool panel (MWWP) is an inorganic-bonded panel product in which wood excelsior is bonded with magnesite. Lowering the hygroscopicity is one of the key measures to improve the quality of the panel. In this study, moisture absorption mechanism of MWWP and measures generally applied to lower its hygroscopicity were reviewed. Three methods were then experimented to improve the dimensional stability of the panel, including adjusting the molar ratio of raw materials, adding additives and optimizing the conditioning process. The results showed that satisfying dimensional stability could be achieved when the molar ratio of More > Graphic Abstract
