Flue material

[Ackoman]

Hello

Is it possible to tell from these pictures what material my flue is made from?

The house was built in 1971 if that helps.

Many thanks,

Ackoman

Asbestos/cement

Was asbestos used in the 70s?

Yes

It could still be used right up till the complete ban in the late 90's .... artex was a favourite to have it along with cement board/pipe products.

artex was a favourite

Ah Artex - I remember my ol' man moving into a place that had an average of 4" long points hanging off the ceiling and getting me and my brother (8 and 12 ish at the time) scraping the stuff off by hand with no protection

The things we got up to back in the day .

Do you think it is safe/possible for me to slide the collar (that is being held by the two jubilee clips) down so that I can get access to the upper section of the flue?

The flue is currently unused - the boiler that it was connected to is long gone.

Bonded asbestos, (asbestos cement), is relatively inert provided it remains intact, breaking it will release fibres. I'd wear a suitable dustmask, and some disposable overalls, damp it down with a garden sprayer, and work carefully. What were you hoping to achieve?

I've installed a fan in the bathroom ceiling and need to route the vent to the outside world

And you want to do this via an old asbestos flue which could release asbestos fibres back into your home?

How will it do that? The bottom section of flue will not be connected to bathroom shower vent, only the top section - that's why I want to move that collar. I was also thinking about capping off the bottom section.

And, it is already capped off at the bottom end i.e. in the house.

Won't the wind potentially blow back down the vent when the fan isn't running, taking fibres with it into your room?

 

[Dan Robinson]

Biggest draft in our house is through an extractor fan.

 

[Ackoman]

Ok, I hear what you guys are saying. The fan does have flaps which are supposed to close it when it's not running, but I do take your point.

Maybe back to the original plan of having a roofer fit an extraction tile.....

The fan does have flaps

So does ours look. They're great for telling me when it's windy outside.
