DIY insulation in action

If you are considering some DIY insulation, here is an update from Ian which may be of interest... "The dining room was made from half the integral garage but there was no insulation in the new wall - just 165mm of blockwork. I spoke to one of the professionals at an Eco House Group seminar in 2010 and he advised insulating it. I bought some 1.2m x 2.4m x 50mm Kingspan foam boards from secondsandco and have put most of them up. I was going to use coving adhesive but Wickes only had 25Kg bags so I used dabs of plaster on the wall and aluminium tape round the edges. I had already lined the metal door with polystyrene to keep a bit of heat in the garage. Also there was a large gap at the bottom of the door so I put 25mm strip of 6mm plywood inside an old bike inner tube and bolted it to the edge of the door."
