Abstract：The non - net casting exterior thermal insulation system on field concrete exterior wall in high storeyed resident building is developed firstly at home. This system adopts polystyrene board without steel wire net as thermal insulation board. The cracking resistant layer consists of polymer cement mortar and alkali resistant glass fiber woven scrim, anchored with plastic expanded tube. The tests of bonding power between polystyrene board and concrete, plastic expanded tube pull- out, compressibility, freeze resistance show the system property is reliable and high safe. The thermal measurement test shows the system can meet the requirement of wall body energy - saving 50% stipulated in Beijing "Energy Saving Detailed Regulations", with low construction cost and high work efficiency. The comprehensive construction cost lowers 40%～50% in comparison with back suspending net system.
