1, easily comes off and hurt sb.'s feelings.Foundation wall and incrustation mortar are inorganic material, combine with organic outer insulation, because its chemical attribute difference therefore in conjunction with insecure, a lot of cases of hurting sb.'s feelings that come off that rise has taken place now.
2, resistance to biological attack is poor.The organic material quality is dredged soft, easily by biological damages such as termites.
3, fire safety evaluating hidden danger is arranged, it is combustion-supporting and produce a large amount of toxic gases to meet fire.Organic combustible material is now prohibited by country.
4, manufacturing process is numerous and diverse, and the material cost fluctuates with oil price, the difficult control of cost.
5, easily aging distortion, the life-span weak point can not with the same life-span of building.
