Weather Resistance Algorithm of Exterior Wall External Insulation of Foam Glass

Wanghu Sun, Lingling Xiong


With the development of economy, more and more new type thermal insulation materials are put into use. However, once encountering awful climate, the cracking and exfoliation from the exterior walls occurs frequently of these insulation systems. In view of these problems, this paper studies the application of the foam glass in building external wall thermal insulation. It firstly introduces the external wall insulation technology and its characteristics, and then elaborates the algorithm of foam glass in building external wall insulation, and analyses through thermal conduction of the foam and thermal conductivity of the fiberglass mesh. Simulation experiments shown that the sintering temperature of glass powder of 120mesh should be around 550-680oC and the foaming temperature of the foam glass mixture should be around 750-850 degree centigrade.
