- How to fit a backdraft shutter to stop cold air entering your home & help you save money on your heating bills! It's a relatively simple (and cheap) device to fit.
Here's the one I fit in the video (make sure you choose the right size for your fan/pipe); amzn.to/3TrcoIq

Great idea trimming that plastic ridge off!
Thanks! 👍
Thank you very much, exactly what I need, hate my freezing cold bathroom. This will sort it out
Hope it helps 😊 Let us know how you get on
I’ve been looking for a solution for exactly the same problem. This looks simple and effective. How did it go, have you noticed a difference?
It was a really easy job to fit.. and cheap :) It's definitely less drafty.. I can sometimes hear a quiet 'tap' noise as the wind from the outside blows it shut, so it's definitely do its job. It's difficult to say whether it makes a difference to the temp in there, but I guess it should be, given the wind doesn't blow through like it used to. We've not smelt the smoke from next door's wood burner as much as we used to either.
Will it stop soil stack smells which is within half a meter from my fan extractor position on a sloping roof outlet? Thax
I would think it would help but maybe instead you can extend the soil pipe.
This looks great! Our extractor fan is right above the shower and on a windy day you get such a cold draft blowing down, it's horrible in winter! Would this be suitable for a ceiling mounted fan?
As far as I know this will only work well if the pipe is horizontal. If it was mounted in a vertical pipe it'd struggle to open with the airflow from the fan (against gravity on the flap).
@@Endpoint101 the us ones are usually recessed in the ceiling and the flap is still vertical allowing the system to still work well despite being ceiling mounted.
I am no tradesperson, but I imagine there’s versions that can be energised on the same circuit as the fan and operate electrically, regardless of orientation
The extractor fan should be strong enough to push the vent open. In fact a vertical installation may be better suited to this type of valve as it won't be prone to tapping sounds in windy conditions.
Just my two bobs worth....
The problem with the after-market shutters are that they clatter in the wind, as gusts open and close them. They are built for price, not quality. How bad this is will differ depending on house location and where on the house the fan is fitted. Some fans come with a built-in shutters that are almost silent. They are built with sturdier flaps and have bump stops to dampen the sound. Despite being a really good feature fan sellers are not keen to tell you about this. There are shutters that are a bendy sheet of plastic, but plastics do not make long lasting springs. If anyone knows of a backdraught shutter of better quality I would like to know.
Thanks for the comment 🙂 Ours does make a tapping sound now & again in gusty weather (like now!). It’s not bad, but could imagine in some places it might do it a lot more often. I too would like to know of a reasonably priced one with a bump-stop. All fans these days should have one integrated in really.
@@Endpoint101 in the US it’s standard for a bathroom extraction fan to have a backdraft damper as well as the outside vent on a wall or roof also has a damper to prevent birds and other animals from entering as well as helping to prevent too much air from coming in . I have some in my house and the noise from high winds isn’t bad. The one in my upstairs bathroom barely makes any noise because it’s defective. 😂
Interesting how things differ between countries. The UK may have that now (it's been fitted for over 12 years). Thanks for commenting! 🙂
@@Endpoint101 also the standard is the same for Canada and Australia too. For cold and windy climates especially wet ones, backdraft dampers are a must.
I have just fitted one of these and yeah it clatters. I have opened it all up and put tape accross the top of distrupt the air flow going in and hitting the top of the valve and also stuck some foam strip to try and stop the clatter....it's better but still too noisy for me.
What it annoying is when I blew a hair dryer in the fan end it opens and blowing a hair dryer in the outside end....it stays shut and doesn't clatter....so the wind must be doing something different cause it to open 🤷
