≤ 2.0% of the dimensional stability of peeled extruded plate, Knauf did some research for this, set the expansion joints through exterior insulation system in the context of a certain area, you can effectively release the layers of the system specified in GB deformation. 


 GB. Extruded board application of a relevant national standard. Thus the number of applications have borrowed to the technical standards of expanded polystyrene board. In June 2009, the Shanghai Construction ASTRI and the National Building Standard Design Institute jointly organize the compilation of extruded plate plaster external wall insulation system of technical standards, while the resistant peking syndicate prepared GB 08CJ16 extruded board insulation system building construction "revision in August 2009 in the National Building Standard Design Institute. The industry is working to strengthen the application of norms and standards of the extruded plate, extruded plate so as to guarantee the rational use of external wall insulation.
