Rock wool blanket is a flexible rolling product covered with iron
wire mesh, stainless steel wire mesh or glass fiber cloth.It is
used mainly for the insulation of large sized pipe and tank, large
equipment, special shape component, valves and pipe fittings. Iron
and stainless steel wire mesh blanket is especially suitable for
thermal insulation of high-temperature equipment,as well as air
conditioning system for the wall and roof of buildings.
Faced roll is a rock wool roll covered with aluminium foil or other
covering materials for moisture proof and enhancing strength.
