Rockwool Fire Insulation , Rockwool Fireseal Loose Wool 750 ºC
Quick Detail:
Fireseal loose rockwool is used in sealing the gap between service pipes and penetrations through concrete floors as fire resistance and thermal insulation applications
Description:
Rockwool (mineralwool) products is an economical light weight thermal insulation material which is well recognized as one of the best material for thermal and insulation purpose is manufactured from a mixture of natural rocks (basalt and dolomite) melted at high temperature to form a molten matrix, which is then passed through an air stream that cools the material and forms long fibrous strands. These strands are bonded together to form slabs, blocks, blankets, pipe covers and granulates (non-bonded). The material is chemically and biologically inert and free from plant pathogens.
Applications:
Loose rockwool is commonly used in sealing the gap between service pipes and penetrations through concrete floors. For it to be effective it must be placed in fire rated pillows for temporary service protection. The fusion temperature of this product is 1150 ºC. Fire collars are recommended for PVC pipes.
Specifications:
10kg per pack or 15kg per pack.
