I have a 1930's semi with a bay on the front on both floors.
On the outside the section,above the ground floor window and below the first floor window, the render is falling off.
It looks like there is felt under it.
I was planning on removing it all so I can insulate it better and then board it and render it.
Can anyone give me advice on what materials to use please?
What insulation, board or felt etc and render mix?
