I find it useful to be able to cover up quickly when the rain starts. If
you reverse the sashes and just pin them in place you can work on the
outside bits from the inside, and at a comfortable height.

Had the same thought as I stood in daughter's bedroom with box frame
on
the floor (in several pieces) and big hole in wall. Improvised a
temporary
window with 4x2 hastily fetched from timber yard, OSB and a handy
spare sash
from the basement.

In a refurbishment all the sill has to do is sit there. It doesn't
really need to be jointed because the box doesn't have to be a free
standing item

As the box is out of the wall I'd like to re-make the joints properly.

Thanks for your comments
