Week 5, Day 5:
- Back-filling the northern GSHP collector trench with a layer of sand and the excavated soil together with a green polythene marker tape about half way down.
- More work on the below-ground cavity walls.
- Fixing the last piece of steelwork, the post for the corner window in the north-west corner of the Living Room.
Week 5, Day 5
North-west corner post
Completed below-ground cavity walls on the southern side; 100mm blocks and a 250mm cavity. The steelwork is deliberately in line with the inner skin of blockwork, allowing for a full-thickness layer of cavity wall insulation (which will be Ecobead Platinum) to prevent thermal bridging.
Steel column attached to blockwork using Ancon Teplo-L-Tie, with a much lower thermal conductivity than a traditional metal cavity tie.
