I am getting quotes to repair a bow window sill repaired and add bottom insulation. The front finger jointed sill has separated. The bow window itself is fine. The side windows work fine and the window does not sag at all.
– For the sill I’m thinking all three sections should be replaced so that everything matches.
– To insulate, I want to support the window, remove the corbels and build a box underneath so I can add insulation. Then replace the corbels. One of the photos is what I am thinking for how I want it to look.
I am assuming that the corbels are not decorative and the window would have to be supported while the box was built. If temporary support is necessary, how can that be done without getting in the way of building the box? The only thing I can think of is cables attached from above the window.
What would be the best type of insulation to use for this to provide good insulation but keep the box from being too low?
