Another day, another disappointing discovery...
Our front upstairs windows have an arched facade to the outside but the sashes themselves are obviously rectangular with an extra glazing bar following the profile of the arch. This means that the outer facing at the top is a big board cut to follow the same profile.
This is all fairly original in the main bedroom and I've put a lot of effort into renovating them this year. You can now see the inside face of the board through the little corner top lights. Very pleased with the result, they went from being my 'worst' windows to my 'best'.

At the weekend I turned my attention to the window in the spare room. I already knew that it had been replaced, probably by the company whose name begins with V who draught proofed all the other windows. The dimensions are all a bit off, 'English' size parting beads, narrower pulley stiles etc. It needs the usual cill and pulley stile repairs and the bottom sash is scrap, just like every other bottom sash fitted by that company. I know what to do with all that.
The great disappointment is that the outer facing at the top is made of MDF. No nice wood grain to look at through the top lights (if one could see past the paint runs) and of course its swollen up virtually jamming the top sash. It was barely even held in place just needing a bash with the heel of my hand to knock it free. So, the task now is to replace with something more durable and more attractive.


The overall size is 1.1m x 0.5m and its 16mm thick. I would be nice to source a single piece, but that seems unlikely. I could possibly join 2 or 3 planks edge to edge with dowels or biscuits. And/or it could be made in two halves. The original ones are one piece, the MDF one is in two halves. I should be able to route out the arch with a jig, fairly certain its a circular section, or worst case use the MDF as a template. 16mm seems to be a very uncommon finished thickness but thats the size of the normal outer facings as well as some other bits like the window boards. Maybe now is the time to invest in a thicknesser...
There are a few places online that will cut to size, but the cost is pretty high for small quantities and I can't find anywhere that would do that width in one piece. Lead time is also quite long. I'd like to get it replaced before the stone guys finish pointing so I recon I have 2 or 3 weeks grace. Wondering if anyone can suggest a source for materials in a size that would minimise the effort?
Or cunning ideas for other things that could be cannibalised? I thought of using the panels from a reclaimed internal door, nice knot free timber but maybe not up to external use and only about 1/2" thick so far as I can tell.
