In it for the long run.

Insulation of pipework through buildings ensures the optimal temperature of both hot and cold water pipes is maintained whilst also controlling condensation. In working environments, it is important to keep temperatures comfortable and stable. High temperatures from pipework can also pose a hazard, but RockLap H&V Sections offer an excellent pipe insulation solution.

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. The sections also have properties that allow them to insulate from frost damage. 

RockLap H&V Sections are used for heating and ventilation pipes in a range of settings, through buildings, plants and other structures. The sections have been proven to deliver high performance thermal insulation in a range of settings with varying climates and degrees of exposure for over 60 years.
