ROCKWOOL stone wool products are non-combustible with a melting point of approximately 1000°C. They are particularly suitable for thermal insulation, fire protection and sound reduction/absorption.

ROCKWOOL stone wool is inorganic and contains no nutritious substance. Therefore it will not be attacked by microorganisms. Stone wool will not rot and does not attract vermin. No CFCs, HFCs, HCFCs or asbestos are used in the manufacture of ROCKWOOL stone wool products.

Common Applications

RockTech WM is particularly suited to meet the specification requirements of thermal insulation, fire protection and sound attenuation of large process pipework, tanks, vessels, boilers and ducts. RockTech WM is suitable where high temperature combined with vibrations or high fire resistance is required. Irregular and circular shapes of equipment can be easily insulated by RockTech WM due to its flexibility nature of blanket type. Retention of the fibres by the 25mm (1”) wire mesh prevents any cracking or breaking. Wire mesh can be made from either galvanized steel or stainless steel materials.

Handling and installation

RockTech WM can be cut to required length and wrapped tightly around the equipment. The edges of each mattress should be butt jointed closely together with an angle of at least 30 degrees to each other to eliminate gaps and stitched using steel wire of diameter minimum 0.5mm. RockTech WM can be secured to the equipment with steel bands or pins with speed clips. All steel components or equipment exposed to a corrosive environment should be cleaned, degreased and coated with a protective finish before insulation is installed into it. The insulation should be finished with metal cladding i.e. aluminum or other approved cladding material. Both lengthwise and circular joints of the cladding are fastened with sheet metal screws or rivets. All the connections within the cladding shall be made watertight using suitable
sealant.

Packaging and Storage

RockTech WM is shrink-wrapped in polyethylene sheets or cling wrap for ease of handling, transportation, storage and identification. Products should be stored indoors or under a waterproof covering. Ensure the insulation is not in direct contact with the floor; otherwise it may become wet as a result of ground moisture.
