twin wall flue

[dgrallying]

i am about to install a wood burner and i am looking to install a twin wall insulated liner but as i am installing it in a bungeralow however as i am looking to build on above in two years time can i extend the liner or would i need to change the whole liner?

Thanks

Its a good while since I was involved in such a project, but a firm called Rite-Vent fixed me up with stainless flue lengths and couplings, and advised me as to the legislation of the day.

If you're talking about the stainless twin wall insulation flue pipe then yes you can. Make a note of the manufacturer flue pipe as I don't know if difference make are slighty difference fittings
