High Temperature Resistant Rockwool Fire Insulation Dark Board
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:
ROCKWOOL dark boards is designed to camouflage the insulation behind glass of the curtain wall is an alternative to black tissue.
