Principles for selecting external wall insulation system
Jul 04, 2021
(1) The principle that the crack resistance of the external thermal insulation system is better than that of the internal thermal insulation system
(2) The principle of anti-cracking technology with gradual gradual change and flexible stress release
(3) The principle that ordinary cement mortar should not be used as the material for leveling and protective layer of external thermal insulation system
(4) The principle of no cavity or small cavity structure to improve the stability of the system
(5) The anti-cracking problem of the protective layer is the main contradiction principle of crack control
(6) All external thermal insulation systems have passed large-scale weather resistance tests to verify the principle of crack resistance
(7) The principle that the paint exterior finish system should be selected as far as possible
(8) The compatibility and matching principle of materials of each layer should be fully considered
(9) Strengthen the sealing principle of the material change of the insulation cut-off part
(10) Principles for suppliers of external wall insulation system to respond to the complete supply of system materials
