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.
