At a glance

It suits Schweigen systems that require a 150 mm duct and offers insulation, acoustic dampening and strong resistance to crushing and punctures. Its main limitation is the shorter 4 m length, which may not suit longer duct runs without buying extra components.

Ease of installation score

8/10 - designed to be safer and easier to install, though extensions require a separate joiner.
