Universal ducting

We've developed this range as a protective solution for channeling ingenuity. This universal robust, yet flexible insulation duct provides future-proof flexibility for any combination of pipes, tubes and cables.

Harnessing creativity

Protectube acts as a thermal, sound, and mechanical barrier for a wide scope of applications, both indoor and outdoor. It can furnish great creativity of use in an efficient, and sustainable solution. Because of its light weight and flexibility, Protectube can be quickly and easily installed under river crossings, railways or buildings, used as feed lines for heat pumps or split air conditioning, ... the possibilities are endless. And they remain endless, even for future replacement or up-scaling.

Cover all bases

Just like our other insulated components, Protectube is made from extruded polyolefin foam to a robust HDPE outer casing, offering excellent thermal performance as well as protection against moisture, humidity, frost and mechanical loads. It is equally safe and environmentally friendly in terms of sustainability and recyclability.
