External wall fire barrier

• Introduction

External wall rock wool fire barrier strip is a kind of strip material processed by external thermal

Insulation rockwool board. Its general density is 100kg/m3—150kg/m3 and has good properties of

thermal insulation, crack resistance, fire resistance and durability.


• Features and Application

External rock wool fire barrier strip is insulation materials with good advantages of low thermal conductivity, good air permeability, higher level of combustion performance. It is mainly used for external thermal insulation engineering of residential buildings and public buildings including external wall thermal insulation engineering, curtain wall thermal insulation engineering and EPS external wall insulation system.
