    Wondering if anyone has any advice regarding wooden cladding?

    I'm going to clad an extension, single storey, and had planned on using rough sawn pressure treated timber, something like a 6x1" board, then paint them.

    I've seen on the ruby cladding website, there is quite a difference in price between cedar/larch and something like bog standard rough sawn softwood. Just wondered if anyone has used either and have any nuggets of wisdom??

    TIA

    rough saw can be crap full off knots warped bent it may even be mostly ok but for rough work also no tounge or groove so not waterproof
    joinery quality far more stable if it is say 6"cladding the coverage will be between say 130-138mm so 5 1/4 to 5 1/2 coverage

    Softwood? Give it 15 years.

    How is rough sawn going to hold paint?

    The cladding I had in mind wasn't T&G, just flat boards or possibly featheredge. I don't want it to look too modern.

    Had painted some panels made of rough sawn treated wood, in masonry paint... I know roll your eyes.:LOL: some 3 years down the line, it looks like it was painted yesterday.
    Ducks back in comparison is very poor, needing another coat every year.

    Cheers, I'd noticed these guys on ebay, larch is not to bad price wise, although still twice the price from the rough timber costs I have.

    Take on board what you are saying about waterproof etc, not a massive concerm for me, as I'm planning to paint.

    Thinking cap on now.

    What's the timber like underneath covered in that sealed in layer?
    Rhetorical I know, as you won't know until it has softened and rotted - and the paint coating may well still look like it was done yesterday.
