Abstract

Building joints always lead to water leakage, wind penetration, and thermal bridges, which especially cannot be ignored in prefabricated buildings. Thus, in order to solve this problem, we propose a novel and feasible insulating element with a multi-layered structure, which can realize waterproof and thermal insulation at the same time. Its performance was evaluated by experiments and scenario analysis, including its water resistance, moisture resistance, cohesiveness, fire resistance, weatherability, thermal insulation, etc. The research results show that, compared with building foundation materials, the proposed building element obtained satisfactory performance: water absorption was reduced from 35.7% to 18.5%; moisture absorption from 7.0% to 2.1%; and weatherability and fire resistance performance were good. The proposed novel insulating element can be applied in prefabricated buildings, and the research can open up new ideas for other related insulating elements with more advanced and better performance which focus on solving problems caused by cold or hot bridges and building joints.
