Preparations for insulation below dpc

Putting external insulation below the damp proof course is rather like giving the house some very warm snow shoes. That and the  insulation below the floor slab and against the walls on the inside should keep heat loss down through the walls to a minimum.

But first, preparation - using insulating foam to seal up around any holes or pipes going through the walls.
And secondly, minimising cold bridging below the front and back door by removing some bricks and putting in a layer of super-insulating marmox thermoblocks.
