any real builder types on here?

right my question is, how best or correct way is it to put a wood burning flue though a corrugated roof ? I have found a rubber boot/flashing which looks to bolt to roof on eBay searching with Google. I'm hoping to not build a chimney so the flue passing though the bedroom will also heat bedroom but if I have to use the twin wall flue will this still give some warmth ?

 

i have a bum crack does that qualify id get a proper proform cravat n upstand if it were me , rubber dont sound to good? it should be fire clad through bedroom too , but your in france soooooo??

 

I thought you'd have to post this request in Polish, isn't that where all your builders come from these days?

 

is a cravat not a piece of gentleman's clothing?

 

god knows what they speack round here

 

Like what barney said , rubber on your flue aint goin to last long and may even get very hot , thats not good ,, if your flue cools in its lenght then you will get condensation which will A, rot the flue causing it to leak and B , run down into the fire .Use twin wall with the proper roof terminal

 

@Keith.H is a good builder.
I'm sure he'll be along soon because like all good builders he does a 5 hour day (inc tea breaks) and works 3-4 days a week (when busy).

 

...and don't forget to insulate your loft with copies of The Sun and old B&H packets...

Personally, I wouldn't run a flue through a cravat. It'll ruin the material.

 

Your in France, stuff it through the roof and cement round it

 

what are you trying to say?

Lump of cement on the roof ,two chimney blocks, viola....

 

As Poptop said

As for the bedroom, a double skin may limit the heat but anything less and you risk serious burns, i know very little about woodburners and flues as we are not allowed to touch them but Machine Mart do a good range and have useful diagrams in the catalogue

Cant find the diagrams on the web site

 

I have heard stress is a killer, so i go with the thinking that prevention is better than cure

 

This type of thing.

i wouldnt use one on a hot flue ?? ok for vent duct but they still leak after time , you neead proper weathering cravat / upstand really

 

Use this one then 100deg hotter

The weathering ring etc should be part of the twin wall set up. This just gets you through the corrugated roof.

 

we used to use dektites but if extreme weather n temp changes n not being fitted correctly they are parp you need a weather sheet if its corrugated that tucks under next sheet with upstand built in to it then fit cravat over upstand with pipe onto bottom and pipe n cowl on top or your asking for trubs realy especially on residential house . Sealant is ok but not 100% as with all stuff and thats what you stick them dektites on with .

 

Looks like we're back to stuff it through the roof and cement round it.
