Week 27, Day 1:
- On Sunday I’d carefully cleaned the areas of the concrete floor that are going to be polished in readiness for the Ram Board protective covering which was installed first thing this morning – this allows the concrete to continue curing while protecting it from damage
- The main photo shows some external wall insulation over the SIPs panels at the top right – see below for a clearer shot
- The cavity wall insulation is due to be installed shortly but the cavity hadn’t been closed so a lot of time was spent carefully cutting and installing insulation boards between the windows and the outer skin of cavity wall blockwork
- There were some small gaps between the plywood frames supporting the doors and windows and the blockwork, which are in the process of being filled with airtight foam – they will also get an airtight tape covering
The starburst shapes mark the location of the electrical floor boxes which have had their lids removed and hence won’t support any weight. Each sheet of Ram Board is roughly 1m wide.
This extra 50mm of insulation was included in the design before the SIPs were manufactured so it intentionally brings the outside of the SIPs flush with the outside of the masonry.
