We have a twin wall flue running through an upstairs bedroom and the wife wants it boxed in. The information I can gather from the manufacturer is that any combustible material needs to be at least 60mm from the flue. So am I ok using a timber frame then standard plasterboard as long as it's 60mm from the flue or do I need to use some heat resistant materials?

Thanks

IIRC it's a 50mm minimum, though happy to stand corrected. Timber frame and plasterboard would do the job too.

Bit of a shame to cover up a heat radiation source within the bedroom though, albeit minimal from a twin wall flue, it'll still help keep the room warmer when the stove is burning.

Use metal studs and pink plasterboard and you can minimise the boxing. You could also put vents in it to use the heat.

There should be a code on the flue about 11 digits long I thInk, somewhere near the end will be a 2 digit number which is CLEARANCE to combustible materials in mm.

ithat means combustible materials can’t be within that dimension, covering them with heat proof board  doesn’t comply as they are still within that dimension.

You can have problems in well draught proofed houses even complying with those dimensions. I know of one property that had a fire because of lack of ventilation.

You could use some open mesh for an industrial look?

Thanks all, I'm quite happy to leave it as it is as it keeps the room pretty warm when the stove is on but it's in the little ones room so the wife wants it boxed in and I don't she would be happy with the open mesh solution purely down to cosmetic reasons.

There is this sticker which gives some info:

So as long as I'm at least 60mm from the flue, timber and plasterboard will do the job? I'd probably have a vent at the top and bottom of the box in order not to lose the heating effect altogether.

You can put anything combustible down to 60mm away if burning solid fuel, wood, coal, peat etc, you dont need to use pink plasterboard, even if you did it would still need to be at least 60mm away because it is classed as combustible.
