Foil Mineral Fibre Sections

Pipework shall be insulated with PAROC / Rockwool pre-formed rigid mineral fibre pipe sections, aluminium foil faced, joints sealed with self adhesive aluminium foil tape.

components: 

Self-Adhesive Aluminium Foil Tape

Bostik T74 High Tack Foil Tape has been developed to deliver instant adhesion, mouldability, durability and reliability even when applying at temperatures as low as -5°C.
Designed for use in the heating, ventilation and air conditioning sector, it is ideal for lap sealing foil faced insulation materials, both rigid and flexible.
It is manufactured to the highest specifications and is coated with a high tack pressure sensitive acrylic adhesive, which is protected by a removable release paper.

RockLap H&V

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.

PAROC Hvac

PAROC Hvac Section AluCoat T is a non-combustible stone wool pipe section for thermal and condensation insulation of pipework and air ducts in buildings and ships. It has a reinforced aluminium foil facing and tape in the longitudinal seam which prevents condensation gives a quick installation.
