neverest® Semiflex 160 - Flexible Aluminium Ducting Ventilation Fan

This is the business. I used the 150mm for a cooker hood. It comes in a box that's no more than 40cm long but due to its construction can stretch out. I probably extended to about 1.5m to join to a high capacity roof tile. It's nice and rigid so you don't get noise when the extractor is on. Perfect for the job. Folks who damaged it must have been doing something wrong....

Don't seem to be Jenny options for 150mm ducting but this fits the bill and works very well. I was able to persuade it around a tight 's' bend where I was concerned it might be damaged against a hard edge but it is resistant enough against puncture damage. You can stretch the concertina out to almost a straight tube or keep it tight fit a sharp bend, it's very accommodating without losing rigidity

Strong but has to be done used strategically; it should be stretched first before implanting as pulling needs enough room, and once there is indentation, it won’t go and there is a risk of tear trying to reshape. Shouldn’t be use where there is enough foot traffic as there is risk of easy unintentional damage

Just wat I needed

This was used for a direct air feed for a new eco stove. The fire is located on an internal was so the duct was laid under the slab. I was a little concerned that it might collapse under the weight of the concrete but all was fine. I stuck my phone inside just to be sure!

This is so amazing. We ordered for our Air conditioner. The previous pipe would make the room a bit warm with the heat. But this is brilliant and keeps the pipe cool and the room is also cooler now. It is worth it specially in this extreme hot weather. We are loving it.

Strong qauility

not great quality, but ok value for money
