Application of Green Building Design Based on the Internet of Things in the Landscape Planning of Characteristic Towns Table 4 External wall insulation technology.
Practice Disadvantage Advantage External wall insulation Wide range of application, suitable for different buildings The insulation layer is exposed to the outdoors, so it is easy to stay Damage, resulting in reduced durability of the material Insulation for external walls The insulation layer has good durability, effectively avoiding external destruction of the environmental protection layer Affected by the surface temperature stress of the external wall structure layer Larger influence, easy to induce cracking of the insulation layer External wall self-insulation (sandwich insulation) Low requirements for the strength and durability of insulating materials The inner and outer walls need to be connected by connecting pieces, the structure is relatively complicated, and the construction technology and process requirements are high.
