RockLap H&V Pipe Sections


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. The Sections are designed for thermal and acoustic insulation of heating, ventilation and air-conditioning pipework operating in the temperature range 0°C to 700°C.

For rapid, efficient pipework insulation


• Resilient, high performance barrier provided by one-piece, reinforced foil with integral lap
• Fast and simple installation reduces costs and time on site
• Installation may be carried out in winter conditions
• Tape requirement reduced
• Class O finish



RockLap H&V Sections are provided with a factory applied foil facing which meets the requirements of Class O with joints sealed using a suitable foil tape.

Self-adhesive lap

The self-adhesive lap bonds effectively at low site temperatures, hence reducing possible delay during winter installation. The adhesive on the lap has been specially formulated to provide an aggressive bond with a long life and high shear properties.


The nominal density is not less than 120 kg/m3.



RockLap Pipe Sections are non-combustible and are rated Class O as defined within the Building Regulations.
