Underfloor insulation

Now the walls are finished it is time to do the floor.
The design means that I can cut small access hatches in the floor and then just get underneath the floor. I started by putting insulation between the joists and held it in with stapled skrim. This was very effective but a really horrible job as I only had a few inches to spare so my face was in mineral wool and it is difficult to work in those conditions with goggles and face mask. So we came up with cutting the insulation in 600mm lengths and put it in black bin bags and then stapled them in between the joists. which was much easier.
