Heat Insulation External Wall Rockwool (construction)

1,External Thermal Insulation Rockwool Board

？ Introduction
 
The external thermal insulation rockwool board is designed for the buildings of external thermal insulation system with thin finish coat and applys to external wall insulation and energy saving of new or existing building whose foundation wall is concrete or brick and other compact structures.
 
The external thermal insulation rockwool strip can also be used as fire barrier to improve the fire resistance of buildings external walls with other thermal insulation materials.
 
？ Features and Application
 
High compressive strength, tensile strength and good durability ensures the reliability and long-term stability of the product in the application.
 
Low thermal conductivity can effectively reduce the heat loss of the building to achieve energy saving and emission reduction.
 
External thermal insulation rockwool boards will not release heat and poisonous smoke because of its incombustibility and can effectively partition the spread of flam when fire occurs.
 
It has good performance of non-hygroscopicity, ageing resistance and long-term stability.
 
It is light weight and easy to be cut and processed.
