Weatherboarding

[rp293]

I'm re-doing the weatherboard on my house with 7" feather edged board which will be mounted on verticle battens.


It's an old 1860s house with solid 9" walls.


Any recommendation for a membrane or paper to use between the wall and the weatherboarding; also should it go next to the brick i.e. under ther battens or next to the boards i.e. on the battens?

so you are trying to make your house look like a shed!

A lot of timber clad homes in Kent.

merlin is a numpty lets not forget, anyhoo, no need for a membrane at all just a drained air cavity of at least say 20mm. But your battens are bigger than that anyway so shouldn't be a problem. Depth of battens 2.5 x the board thickness if I recall. A good coating of Thompsons or similar prior to the battens wouldn't go a miss though. Post back if you want more info or guidance on fixing it or junctions or whatever.

There are highly convincing alternatives to timber BTW. No maintenance and cheaper than timber and the ever horrific upvc. Lots of colour choices too.

The house is only weatherboarded on tha gable end as it's very exposed to the weather and I'm guessing in the winter damp probably seeped through the brick.

I have removed some of the exitsing boarding which has been there many years and there is a membrane/bitchimin paper between the boards and the battens.

I was assuming it would be prudent to reinstall another layer of something; would be unhappy to go to all the effort of doing it and then have a damp issue. Is there any downside to installing the membrane?

Any advice on which membrane to use?

When butting the planks up is that best done on top of a batten so you can nail the ends flush ... I had read not to nail them at the ends to avoid splitting ....

Breathable membrane as used under roof tiles.

There will be no harm caused in using a breather membrane, something like Tyvek Housewrap will be fine. Your cladding supplier should be advising you regards to batten centres, nail length/positioning, substrate depth etc etc.

Yes that'd be OK, try ebay for good prices though!

Spoke to a really helpful guy at Permavent.

He recommends this; http://www.permavent.co.uk/products.eco.html

And recommends to fit it between the battens and the weather board i.e. not against the brick.

Somthing about thermal gradients etc etc ....
