re musical window sill

Unless you ft it flush to the facia anything you mount to the sill should 'float' otherwise you're going to end up with water trapped between the fins and the sill.
I wonder if there would be any acoustic benefit to filling the existing sill with expanding foam?

Sorry I should have been clearer, the rain-brow will go above the window, attached to brick or cladding to deflect drops away from the sill below. Not planning on attaching anything to the sill itself.

Heh, foam might help in the meantime. Certainly worth considering for any stray drops anyway.

cheers
