Nick1c Posted May 23, 2020 Share Posted May 23, 2020 The frame of our house is being clad in a mixture of cedar & render, with some pressed aluminium details. The carpenters on site have been great, but over the last couple of days have been battening out one of the elevations with untreated softwood. We are on an exposed coastal site & they have been using stainless fixings. I have asked if this is a good idea & been told it will be fine as the cladding will (should?) keep it dry, it does however make me nervous. There are three options - leave as is, leave it up but paint with preservative or tear it down & replace with treated timber. Which of these is the sensible route?

LA3222 Posted May 23, 2020 Share Posted May 23, 2020 I think for outside I'd be using treated timber - I don't have a technical reason for why, just that like you, my instincts say outside should be treated. Link to comment Share on other sites More sharing options...
nod Posted May 23, 2020 Share Posted May 23, 2020 I cladded this two weeks ago and used normal tile batons Very quick and easy Link to comment Share on other sites More sharing options...
Temp Posted May 23, 2020 Share Posted May 23, 2020 Regular tile battens are always pressure treated, probably for good reason. Can't see why cladding battens would be any less critical. Link to comment Share on other sites More sharing options...
Gone West Posted May 23, 2020 Share Posted May 23, 2020 My BCO insisted that all external softwood be treated, even behind cedar cladding. Link to comment Share on other sites More sharing options...
nod Posted May 23, 2020 Share Posted May 23, 2020 We inherited this job The guys that where doing it had there materials delivered Then they decided to Furlough Three weeks in the company asked us to drop on it for a week so that the scaffolding could come down We do a lot of battening for cement board and render Always treated tile batons 65 mil STAINLESS screws Link to comment Share on other sites More sharing options...
Nick1c Posted May 23, 2020 Author Share Posted May 23, 2020 Thank you. It sounds (as I thought) that they should be treated - the next question is take them off & replace with tanalised or paint with preservatives. I suspect the former ?. It’s not just 25mm batten as the rainwater down pipes are hidden behind it. Link to comment Share on other sites More sharing options...
Miek Posted May 23, 2020 Share Posted May 23, 2020 I don't see why you can't treat it in situ. What fixings? If screws then you could remove it, if ring shanks then definitely leave in place 1 Link to comment Share on other sites More sharing options...
Mr Punter Posted May 23, 2020 Share Posted May 23, 2020 You could also use stainless staples to attach some cheap dpc to the faces. Link to comment Share on other sites More sharing options...

All the Batons that are used are pressure treated Just the same as the ones on your roof The membrane and cladding or render Baird will keep them dry as a bone The building pictured Had been built and stood empty since 2008 crash The guys that cladded originally had battened out and boarded directly without a membrane So all had to be stripped off Even the batons that where in perfect condition Link to comment Share on other sites More sharing options...
