Ground floor insulation progressing

Steadily, the insulation of the ground floor is progressing.

Conveniently, there was a nice flat layer of concrete about half a metre below the lounge and dining room floor joists. The kitchen floor, on the other hand, needed to be dug out to a depth that would allow for the 300mm slabs of insulation. (It's quite a step up to the back door right now)

Beneath these slabs are downstands of the same insulation around all the walls (as deep as the underlying concrete would allow). These downstands are to minimise the heat lost into the ground through the walls by insulating on both sides of the walls as far down as possible.

And finally, upstands secured and taped, and expanding foam trimmed ready to receive the concrete.
