This document discusses sustainable building materials and construction techniques. It provides information on using thick, insulated walls and roofs made from natural materials like timber, clay, and cellulose fiber for thermal mass. It also discusses vapor permeable wall designs, load-bearing timber blockwork, rammed earth walls, and clay board finishes as eco-friendly options. The goal is to use renewable, recycled, and hygroscopic materials that regulate moisture naturally.
6. EVT Enhanced Vapour Transfer
Hygroscopic insulation
maintain their performance
even when wet
Vapour and water released
when conditions permit
No need for Vapour Barrier
Use vapour permeable
construction
5:1 ratio vr inside:outside
and an air tightness layer
