Passive House in Melbourne: five lessons learned

What we learned delivering windows for our first certified Passive House build.

Passive House certification demands near-zero air infiltration. Our first PH project taught us that installation detail matters as much as product specification.

Key lessons: tape every perimeter, use compressing foam tapes on the internal seal, and always instal from the warm side. Triple-glazed IGUs are non-negotiable in climate zone 6 if you want to hit the heating demand cap.
