Chimney Wind Noise Driving Us NUTS -Help!

    Hello
    Our chimney works fine but when the wind gets up, which is often here in Galway, it makes an awful loud noise.
    Like blowing across the top of a beer bottle.
    It seems to get amplified in the chimney.
    like i said the chimney works fine- there is no down draught.
    Id rather not get one of those dampners which you pull up and down to seal off the chimney.
    They cost a packet (almost 400 euro) and we use the fire quite a lot.
    Where can i find a cowel yoke which reduces noise?
    Any of the suppliers/hardware stores i ask they say "We have cowels but there not designed for noise"
    Any help/advice appreciated...
    Thanks:(

    Maybe the answers in the question!

    If it sounds like blowing over a beer bottle... maybe a cowl that turns away from the wind will prevent air blowing over the chimney - preventing the noise.:)

    But the wind changes...i mean there just doesn't seem to be anything on the market to deal with this problem.
    ive been phoning around for weeks.
    I could write a thesis and/or bore the arse of you down the pub on the subject of wind noise & chimney cowls.

    I was refering to a cowl with a moving fin, that moves when the wind blows. It always has its back to the wind, so to speak. I have seen these in operation so they must be commonly available.
    Good luck.

    They are readily available, from any builder's providers, but they are not great in strong and variable winds (like on a chinmey that's close to trees or other buildings. I had one on my house for a while, but it kept spinning round as the wind changed, and frequently spun into the wind momentarily, causing interesting smoke screens inside the room. Personally I would try the stainless steel fixed type with louvres on each of the square sides. These divert the wind upwards away from the top of the chimney. They are quite cheap and easy to fix, and again any builders providers should have them.

    That's one of many. There are also round ones with a similar design but with horizontal louvres. The main point is to break up the wind as it passes over the crown of the chimney pot. Think of it like your analogy of blowing over the top of a beer bottle. There is only one way of pursing your lips that will create the sound, and if anything disrupts the blow then there is no sound:)

    I'm surprised that no-one in Galway knew what you wanted. I live in Waterford where at least two could supply the things.

    Slightly different answer to what you're looking for I expect but when I had exactly the same problem, I installed a stove so as to be able to control the airflow (and noise) up the chimney.

    It certainly has been a success, great heat, no noise and no draughts!

    Just curious but whats your objection?
    Aesthetics?
    Cost?
    Hassle?

    Installing the chimney closure will cost as much as the smallest stoves on the market...

    I definitely sense hostility. :rolleyes: Not sure if you have any much appreciation for those who have given their opinions and taken their time to try and help you. Perhaps you should go postal!!

    I'm sure the nice folks in here will accept your apology and hence no harm done!

    Coming back to your problem, the only thing I can suggest to keep costs down is to get the chimney damper and do a self install, if its possible for you to do that, i.e. hany with the hands and all that. I seen this type of damper in some of the better builders providers for about €160, a lot cheaper than the crowd that come and fit.

    However, if you've a fire on, this damper sits above the chimney pot and in this scenario, I don't know if it'll cut down on the noise all that much.

    I hear ye. :D

    Well, your options have been laid out here;
    1. change cowl
    2. have chimney damper installed (or self install).
    3. have stove installed.

    Little bit more planning, outlay and effort required for option 3 - but you reap the benefits (and not just in terms of cutting out howling wind) in the long run.

    Art6: I have recently fitted a round 'Aerocowl' with horizontal louvres and I am afraid it may have made the noise worse. The manufacturer says it increases the laminar flow of air - but told me that it should lift the air flow enough above the chimney top to stop it. It has not. The noise only started after we had put a stainless steel liner in the chimney. I have just read a suggestion for a spiral fin (a bit like the spiral radio aerials you used to see on cars) which might break up the air flow. Any thoughts?


    ...and Merry Xmas to all

    After spending hundreds on 3 different cowls
    We gave up and had to get our chimney sealed at the top with an old slate.
    No fire use, but the wind noise is gone.
    No we have a problem with stuffy air and a fume type smell when we have the Central heating on.
    its never ending!

    Sorry, couldnt help myself :p

    I had the same problem and installed a wood stove. Never looked back, best money I spent on the house. Looks great, fantastic heat and I can controll the air flow. Self installed and outside of the stove, cost very little, just a bit of work.

    If it really sounds like it is the sort of sound you get blowing over the mouth of a bottle, I personally would consider putting a masonry disc on an angle grinder and then cutting the top lip of the pot into a castellated or saw tooth profile. Might work, might not. sometimes you just have to experiment.

    Alternatively, most anything that stops the wind blowing across the top of the lip and resonating should kill the sound. Something like this:

    Yeh and the next time the wind blows it might start whistling Oh Danny Boy... :)

    It'd be on Youtube all over the world :D

    I had a problem with down draughts for years, and I tried all sorts of devices, none of which worked. Then I bought a spinning one (see http://chimneycowls.ie/files/Spinner-Chimney-Cowl-Information-Sheet.PNG) from a local builders providers. It was expensive -- €90 at the time, and it works quite well. It spins in the wind and with the thermal lift from the fire, and it does stop the down draughts. The only problem with it is that I live in a rural area and can burn ordinary Polish coal, and every now and then I have to get up on the roof and clean the soot out of it or it stops spinning. Not a big deal for me as I live in a bungalow, and a few clouts with a stick gets it going again! If you live in town and use smokeless fuel or just logs then I wouldn't think that would be an issue.

    have you tried a black bin bag filled with something like bubble wrap and pushed up the chimney? Is easy to put up and take out when having a fire.
    Now this may or may not stop the noise but is a cheap easy thing to try

    I have this installed on my chimney and I find it quieter since I put it on. I got it in my hometown's hardwear store (Dohertys in Roscrea) but cannot remember the price. Around €100 iirc. It spins with the wind and stops it blowing across it.
