Hygrothermal criteria for design of cross-laminated timber external walls

In terms of hygrothermal performance, solid wood panels such as cross-laminated timber (CLT) are sensitive to moisture. However, the previous studies on the hygrothermal performance of CLT external envelopes have not indicated the critical moisture conditions for CLT external walls. Therefore, our main objective was to set limit values as hygrothermal criteria for the design of CLT external walls in terms of moisture conditions using a stochastic approach to ensure safe hygrothermal performance. Hygrothermal performance was evaluated by simplified 1D validated calculation models based on the field measurements [1].
