— Assembly Structure ／ Exploded

Composite structure

/ 01

Outer Jacket (opt.)— protective outer jacket

3.0MM · OPTIONAL

An aluminium, PVC or GRP jacket can be added where the run is outdoors or exposed to knocks, UV or fire.

/ 02

Adhesive Seam— self-adhesive sealing strip

0.5MM · SELF-SEAL

A self-adhesive strip is applied along the factory-formed slit, so the insulator snaps onto the pipe and seals without tools.

/ 03

Insulation Core— insulating core · 3 types

25MM · SELECTABLE

Choose one of three core materials according to fluid temperature and environment.

ElastomericNBR/EPDM foam. −50 to +115 °C · the standard for chilled water, hot water and HVAC.
PU FoamDense urethane. λ 0.023 W/mK · for cryogenic and refrigeration lines.
Silicone FoamUp to +200 °C. For high-temperature steam and chemical plant.

— Applications

Applications

/ HVAC

HVAC Ducting

Stops condensation on cooling and chilled water lines while holding down heat loss and noise.

/ CHEMICAL

Chemical / Industrial Piping

Insulates process pipe and steam lines, slows fire spread and keeps hot surfaces safe to work around.

/ CIVIL

Cold / Hot Water Pipe

The usual answer for building water, hot water and fire lines: freeze protection, lower energy loss and less condensation.
