Constructing window bucks
I’m getting ready to cut the pieces for some window bucks. I’ve read this article: https://www.greenbuildingadvisor.com/node/42336 but it doesn’t specify how to attach the 3/4″ plywood pieces to one another – I’m going to use a waterproof glue, but should I use screws or a 2″ 18 gauge brad nail?
My walls are going to be 4″ of XPS, and I will be making an 8″ wide window flange for the flanged window units to attach to.
Additionally – it mentions for windows wider than 3′, a 2×4 should be placed below the sill for support. Should this be located at the inside or outside of the box? Or do I have to frame a bottom support the same depth as the foam?
