Week 8, Day 4

Week 8, Day 4:

  • The main team of bricklayers started today and they’ve been working on the cavity walls above the floor slab.
  • This included installing the layer of Marmox Thermoblock for the inner skin of the cavity wall. These are made from rigid plastic cylinders enclosed in a foam matrix and help to prevent heat conducting down into the foundations from the inner skin of blockwork. It would be unusual to see these on anything other than a Passivhaus. Further details below.

Week 8, Day 3

Week 8, Day 3:

  • Another day without a huge amount of visible progress, mainly because the team of bricklayers due to start work on the blockwork above the ground floor level were delayed on another job and are now expected to start on Thursday instead.
  • One key piece of preparation was making the wooden templates for the window and door openings that the bricklayers will work to. The plan is to have the window supplier (ecoHaus Internorm) measure the openings in the blockwork and then make the windows to fit the measurements, which provides a bit of leeway in case the blockwork isn’t quite spot-on. Photo further down, taken later in the week.
