Study on Thermal Insulation Performance of Cross-Laminated Bamboo Wall

In recent years, bamboo, as a green building material, has attracted more and more attention worldwide. Inspired by the investigation of cross-laminated timber in structural systems, a new engineered cross-laminated bamboo (CLB) consisting of the cross lamination of bamboo scrimber plates is proposed in this paper. To evaluate its potential in structural applications, the thermal insulation performances of the CLB walls and CLB walls with the EPS foam plate were studied and evaluated by the temperature-controlled box-heat flow meter method. Test results indicated that the thermal insulation performance improved with the increase of thickness, but different wall configurations had little effect on the thermal insulation performance under the same thickness of the CLB wall. The thermal insulation performance of EPS-CLB composite wall was much better than that of CLB wall. In addition, a relatively acceptable accuracy of the theoretical calculations was proved. Finally, the influence of different locations of the EPS foam plate on heat transfer coefficient can be neglected as it was studied based on the validated numerical models.
