100mm Wide by 10m Long Insulated Ducting for Heat Recovery Ventilation

Better than the previous one I bought, this one is much more robust and you can bend it and secure it without it splitting, for 10m of ducting of this quality I can't fault it.

Used this insulating pipe to reduce the condensation

Amazed how small the package was, I only needed 2 metres but as I opened the bag it just kept getting longer and longer...Now I have 8 metres of ducting that won't go back in the bag. I have no idea how they pack it.Ducting is made up of 2 separate aluminised film lengths with glass fibre in between, there's a polythene tube liner as well so it looks like it should last.The insulation expanded at the same time as the ducting, and hopefully it will prevent heat loss and condensation.

Works and seems to have no holes. The fiberglass will get in to your hands when cutting if you don't wear gloves.

Arrived when stated and seem to be doing the job well only fitted yesterday

Wanted to use this on a bathroom extractor, how long it will last god only knows I checked the items Q&A section and it mentioned item was non-perforated only realised it is perforated when I cut the ducting to install.Received quickly and well packaged. Shame it might not be fit for dealing with moisture but is very quiet so is likely to be acoustically ok

This insulated flexible vent hose stops the moist extracted air from condensing and collecting within the hose in a cold loft space compared with a none insulated hose.Should have bought it years ago.

The insulation isn't what I expected. It doesn't seem as heat retaining as other makes I have used.
