are you suggesting that noggins should not restrict 100mm celotex being above walls? see picture

The idea is that the wall insulation meets the roof insulation to form a continuous layer.

You would form the roof, with the joists either side of the wall as required and fixed with noggins as required, and place the insulation above the walls in the void.
