Abstract：A new type of modular thermal insulation wallboard with thermal insulation，sound insulation and decoration functions has been developed. The modular wallboard is made up of bamboo wood fiber integrated wall panels，vacuum insulation panels and aerogel felt. It has excellent insulation and sound insulation performance，good fire resistance and high efficiency in installation and construction. Thermal and sound insulation performance tests were carried out for the new modular insulation wallboard. The results show that the heat transfer coefficient of the wallboard is 0.36 W/（m2·K） and the weighted sound insulation is 35 dB，which is suitable for improving the comprehensive performance of passive low-energy buildings and envelopes of existing building.
