Simulation of heat and moisture flow through walls covered with uncoated medium density expanded cork

Investigation of material characteristics and hygrothermal performances of different bio-based insulation composites

“…The measured thermal conductivies are close to or in the range of other reported measurements, i.e. 0.037 to 0.041 W⋅m − 1 ⋅K − 1 for cork composite [15], 0.034 to 0.09 W⋅m − 1 ⋅K − 1 for grass composite [18], 0.038 and 0.06 W⋅m − 1 ⋅K − 1 for hemp composite [4], and 0.0404 to 0.0578 W⋅m − 1 ⋅K − 1 for mycelium composite [22].…”

“…A comprehensive hygrothermal characterization of expanded cork for building facades is provided by Simões et al [16], where the studied cork boards are observed to have low thermal conductivity ranging from 0.037 to 0.041 W⋅m − 1 ⋅K − 1 with good resistance during long term durability testing. Relevant heat transfer modelling and hygrothermal simulations on the cork boards have also been carried out by the same research group [17,18] and provide valuable insights into heat and moisture transport phenomena under the simulated built environment. An overview of grass-based composites is presented in [19], showing average thermal conductivities between 0.034 and 0.09 W⋅m − 1 ⋅K − 1 , and also highlighting their good sorption desorption capability.…”

Performance parameters of ETICS: Correlating water resistance, bio-susceptibility and surface properties

“…The highest value of increase was obtained for S9 (5.74%). However, Tadeu et al [60] concluded that for an ICB uncoated wall, moisture along the ICB is only high when the outer moisture is high and remains that way for a long period of time. This can be explained by the rather slow process of moisture diffusion within the ICB.…”

Development and Testing of Advanced Cork Composite Sandwiches for Energy-Absorbing Structures

“…Suberin is practically infusible, and it is insoluble in water, alcohol, ether, chloroform, concentrated sulphuric acid, and hydrochloric acid, among others. Expanded cork is fully recyclable, reusable, and biodegradable, and it has also been found that medium-density EC is also resistant to long-term exposure to external conditions [ 46 , 47 ].…”
