Foil Faced Mineral Fibre Sections & Isogenopak
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. Covered with 0.35mm thick Isogenopak sheeting.
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.
Isogenopak (0.35mm)
Isogenopak® is a rigid vinyl film designed to wrap around industrial pipe insulation. The film’s inherent curl means it covers pipes quickly, reducing installation time especially with overhead piping. Its smooth, light grey surface creates an elegant finished look that resists damage from acids, alkalis, salts, and aliphatic hydrocarbons. As a protective surface, the film is impervious to gases, grease, and oil, and is virtually impermeable to water vapor.
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.
