The window sill work got started on the weekend. The timing was dictated by the fact the bay window needs to be fixed into something solid at the bottom - this is a job that needs to be done but not until 1st fix carpentry when the window boards would be going in.
The thing here is to ensure that we dont' create a massive cold bridge by the concrete filling conducting heat into the stone window sills. To do that, the DPC membrane is pulled up tight on the sill and against that a 1" thick layer of ICF insulation is placed along the DPC. Then concrete can be poured into the gap between that insulation and the internal ICF wall. I used can-foam to try and fill any gaps at the bottom or where multiple sheets of insulation were used.
