Fireproof Sandwich Panel Rock Wool (construction)

4,Rockwool Sandwich Board

？ Introduction

The core materials of rockwool is designed for the sandwich boards with mental panels which use the rockwool as coe materials, the painted steel panels and other mental panels as facing.
 
It has good properties of fire resistance. thermal insulation, sound insulation and noise reduction, is the ideal choice for external wall panel, roof panel and internal partition wall panel.
 
The core materials of rockwool will be made of rockwool strips and be bonded with mental panels and then the rockwool sandwich board with mental panel is manufactured. Its vertical fiber structure make it has high shear strength, compressive strength, and tensile strength.
 
？ Features

,Rockwool core material has stable strength and durability to ensure the reliability and uniformity of rockwool sandwich panel.

,Rockwool core materials has excellent fireproof performance and do not release heat and poisonous smoke when fire occurs.

,Rockwool core material has excellent thermal insulation performance which improve the thermal resistance of building maintain structure to reduce the heat loss and achieve energy saving.
