What do people use to cover the ducting for cooker hood

Zoe02

Hi All,

nearing the end of this renovation but I insisted that the cooker hood be ducted out but now this is like this.

Is there something that can be used to cover it or what do people usually do in such case

Good move to have it ducted outside - a far superior option. 

Options for covering it would include boxing it in, using something like MDF, but I wonder if a simpler option could be to use square or rectangular rigid ducting instead of the flexi pipe?

Not sure what sizes are available - have a look on Screwfix or eBay?

What I did with my cooker hood ducting was to run it to the outside wall above the ceiling. The joists ran the right way, and I used smooth rectangular ducting (better air flow, so less noise). Obviously, running the ducting in the ceiling isn't an option for many. So I would recommend rectangular ducting which won't look anywhere near as bad as the flexi stuff. If you still want to hide the ducting, boxing it in is the only real option.

There are different sizes, and also round-to-rect adaptors. 

Might need a primer, although light keying might be enough, and then it can be painted the wall colour.

It's a ground floor flat celling not an option. think the rectangular rigid ducting will be a better choice than what is there currently.

If it was to be boxed in will need to come all the way down or they can do a small box?

Will research online to try and find where to buy square or rectangular rigid ducting

Maybe  should have just gotten the wall extractor fan.

https://www.screwfix.com/p/manrose-110-x-54mm-flat-channel-1m/14118 there was a question and answer that has me unsure now, 

"can this be used for cooker hood extraction ducting

wasn’t sure if its meets regs ?

 This depends on the airflow rate of the cooker hood. Most cooker hoods have a high extract rate so may not be suitable."

No, it would not need to come all the way down, and I think boxing the existing ducting would look better than rigid ducting. Fairly simple DIY job to fix a section of MDF to the wall just below the duct with another fixed to that in front of it, then paint it to match the wall.

Boxing in the existing flexi is as said above - it just needs two flat panels, eg MDF. The tricky bit is attaching the edges to the wall and ceiling. 

There's a larger rectangular ducting too, but tbh for such a short run I wouldn't anticipate any issues. And, the insides are smooth, unlike the ridged Flexi pipe's.

Another, but more involved, solution would be to span a panel above the hood, say if you had wall units there anyway. With cornice, it should hide any ducting up there.

You can’t really use rectangular ducting now, as there is now a large cutout in the side of the stainless steel hood.
so just box it in with ply/mdf and paint to match the wall, hopefully it will blend in.

Quite possibly. But it may be a pre-cut round hole, in which case the round-to-rectangular adaptors should pretty much cover it. And if the RH side it next to a wall, perhaps that side isn't as visually obvious.

But, Zoe would need to make these judgements.

Gluing a rect duct to the ceiling corner and painting it the wall colour has to be by far the easiest and least obtrusive solution. Provided it can be done :-)
