Passive House

These are a series of posts about our journey to design and build a passive house in Stawell, near the beautiful Grampians National Park.

  • Airtightness

    SIPs building are naturally more airtight than a traditional timber framed house. Proclima product for internal walls, called Intello Plus, however, because of the airtightness of the OSB, all we had to do was use the Tescon Extora tape over each join.

Floor Panels The floor panels have a thickness of…

To avoid concrete entirely, we chose a footing system manufactured by Mega Anchor. These steel foundations utilise three rods per footing, which are…
