    Product Description

    25mm Thick 17mm Bore Rockwool Rocklap HV Pipe Insulation Sections

    25mm Thick 17mm Bore Rockwool Rocklap HV Pipe Insulation Sections

    RockLap H&V Pipe Sections

    ROCKWOOL RockLap H&V Sections are pre-formed sections of stone wool insulation, manufactured pre-slit for ease of application and have a layer of factory applied foil facing and a self-adhesive lap. The self-adhesive lap allows the sections to be snapped onto the pipework, then backing tape used to completely seal the joint. 

    The sections have been designed to provide acoustic and thermal insulation to heating, ventilation and air conditioning pipework, from temperatures of 0˚C to 250˚C.  In addition to insulating to save energy and minimise heat loss, insulation is required to services and equipment for other specific criteria such as Frost Protection, Condensation Control, Personnel Protection and Acoustic Control.


    RockLap H&V Pipe Sections are strong lengths of pre-formed insulation with a one piece, factory applied foil facing with integral self-adhesive lap. The integral lap ensures fast and easy installation: just snap the sections onto the pipe, peel off the backing tape and smooth down for a completely sealed joint.

    Other product properties

    Water resistance: RockLap H&V Pipe Sections are water repellent. However, when used or stored in the open, the insulation should be protected with a waterproof covering. 

    When used to insulate cold pipes, the joints should be sealed with foil tape to prevent condensation.

    Service temperature: RockLap H&V Pipe Sections are used to insulate pipes operating at temperatures in the range 0 to 250°C. The sections are used to insulate against frost damage. For hot pipes, the limiting temperature of the outer foil face is 80°C to maintain facing

    bond strength.

    pH neutrality: ROCKWOOL insulation is chemically compatible with all types of pipes, equipment and fittings. (Guidance is given in BS 5970 regarding the treatment of austenitic stainless-steel pipework and fittings). Stone wool insulation is chemically inert. A typical aqueous extract of ROCKWOOL insulation is neutral or slightly alkaline (pH 7 to 9.5).

    Durability: ROCKWOOL stone wool insulation products have been proven in service for over 60 years, in a wide range of climates and degrees of exposure. ROCKWOOL insulation will generally perform effectively for the lifetime of the building, plant or structure.
