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 4

The layer of Marmox Thermoblock just above the beam-and-block floor

An excellent diagram from http://www.marmox.co.uk/products/thermoblock showing where it fits within the floor and wall construction

Week 8, Day 2:

While there’s not a huge amount of visible progress apparent since yesterday’s photo (apart from the evidence of more rain) it’s possible to make out some black rectangles which are the vents for the under-foor void. See the photo further down this Post, taken later in the week.

Week 8, Day 2

One of the vents for the void between the oversite concrete and the beam-and-block floor

The standard vent kits are designed for a narrower cavity so some adjustments were required.
