    A joiner has told me about windows he made from green western red cedar. He used it green as apparently drying it affects the durability?
    As a popular cladding presumably durability is ok, but what about movement or any other issues with cedar in this application?

    He's either pulling your leg, there's a misunderstanding, or he's an idiot!

    How is he going to keep the wood from drying out and shrinking and warping to b*****y after the windows are made/installed?

    It HAS to be dry (or permanently immersed in water) to be durable .

    But not too dry. You don't want to kiln dry it to 10% and then hang it up in the rain.

    Henry, I might have got something wrong on the 'drying affecting durability', but he did use it green as he stated that some was wetter than the rest. The windows have been in place for 18 months or so with no reported problems and am curious to have a look if I can, although they have been painted apparently.
    The movement issue rang a few loud alarms in my mind, but just wondering how stable WR cedar is in relation to other timbers, particularly in typical window frame section dimensions.

    On a more general note, do window fixings into the building structure limit timber movement appreciably in any way? Also does the window frame structure itself limit movement? Would have thought the two factors combined would help to some degree?

    They will and so will the glass but you can get problems with the opening sashes and glazing beads. I have made some non opening windows for a porch with cedar with no problems and no decoration 16 yrs ago. I omitted the bottom glazing beads and had toughened single glazing. Sometimes I wonder why cedar is not used for sills more often.
