    Morning all,

    We're in the process of renovating out house and will be having replacement windows, one of which is a smallish 3 panel bow window. I have been told I need to source a new window board to replace the old laminated brown original which is 600mm deep.
    It seems my options are 600mm polyboard, which I really don't like, MDF or solid timber. I was going to be painting them white.

    Everywhere i've tried locally only has 300mm mdf boards.

    Hoping for some advice on way forward.

    Thanks

    Solid wood will almost certainly need to be made up of 2 or more boards jointed together to get a 600mm width in a single piece. It will probably be a special unless you consider using 28mm thick staved oak kitchen worktop or the like (which you'd need to get someone to edge profile). Not so sure that I'd like the look of that. Also not sure how stable it would be in the long run

    I have tried edge jointing two MDF boards in the past, always with mixed results (even in MR-MDF I could always see the join after fulling and painting). On the other hand you can buy MR-MDF in appropriate thicknesses (i.e 22 or 25mm) as full sheets, so I'd look around for a local timber merchant who offers a machining service and can supply, then break down the sheets to the appropriate width, profile the front edges, rebate the back edges and finally spray prime them so that they are ready to install. Standard sheet sizes available include 8 x 4ft (2440 x 1220) and 10 x 5ft (3020 x 1500mm) so you'd easily get to 600mm boards out of a standard (8x 4ft sheet), but in MR-MDF, non standard size boards and/or thicker than 18mm you may need to wait a few days or a week for them to get it in stock and allow a few more days to machine and spray it

    That is how I've sourced non-standard boards for a number of projects (granted, I'm trade, but these places do exist). At a pinch, though, with a circular saw, a 1/2in plunge router and fence and a profile bit you could machine your own from bought-in MR-MDF
