The objective of this study is to determine the water properties of bio-based insulation materials, derived from winegrowing co-products, which promote energy efficiency. The water performance of these new bio-based materials is based on the measurement of the moisture buffer value, the sorption isotherm, and the water vapor permeability. Four by-products are analyzed: stalks, grape pomace, crushed stalks, and skins; they are combined with a potato starch binder. The performance of these composites is compared to two other bio-based composites (hemp/starch and beet pulp/starch). The stalk/starch composite can be classified as a hygroscopic and breathable material with excellent moisture retention capacity.}, language = {en}, number = {3}, urldate = {2022-01-28}, journal = {Materials}, author = {Badouard, CĂ©line and Maalouf, Chadi and Bliard, Christophe and Polidori, Guillaume and Bogard, Fabien}, month = jan, year = {2022}, note = {Number: 3 Publisher: Multidisciplinary Digital Publishing Institute}, keywords = {agromaterials, bio-based composite, hygric properties, hygrothermal performance, renewable raw sources}, pages = {815}, }
