Insulation Tubes
Closed-cell elastomeric (NBR/PVC) insulation tubes for HVAC, plumbing and refrigeration pipework — supplied as full sleeves or pre-slit for retrofit work, with optional aluminium-foil lamination or a self-adhesive closure.
Key advantages
- Closed-cell and condensation-resistant — protects cold lines from sweating.
- Pre-slit option lets you wrap existing pipework without dismantling it.
- Wide service temperature range, from refrigeration duty to hot water.
- Aluminium-foil lamination available for outdoor and UV-exposed runs.
- Cut to clean lengths, so site installation and waste are easy to control.

Frequently asked questions
Pre-slit or full sleeve?
Use full sleeves on new pipework before it is installed. Choose pre-slit tubes when insulating existing lines that cannot be dismantled; the slit is closed with adhesive and then taped.
Which wall thickness should I choose?
It depends on the medium temperature, ambient humidity and pipe diameter. Send those three values and we will recommend a thickness that avoids surface condensation.
Can the tubes be supplied with aluminium foil?
Yes, foil-laminated tubes are available, and they are usually specified for outdoor runs or where a vapour barrier is needed.
