when boredom meets passion

Yep, as I said... We build over sized outhouses here and call them a home. In the model I am incorporating the double skin decorative but using readily available materials in the right way... No extra build costs for exotic imports or supplier pushed product.
This model came about due to finding out that the Australian Building Construction Board (ABCB) is looking into an epidemic of fast rotting/failing roof trusses. This came about from new builds using a single skinned reflective wrap that seals the house off from external water penetration BUT also seals in water vapour already caught in the house. Their focus seems to be on making houses more breathable and adding a reflective wrap with build in bulk insulation attached to 1'side.
My model is trying to incorporate a sealed framing panel with reflective wrap on both sides to reflect the temperature radiating onto that side (remember everything above zero kelvin [-270C] is heat) then in the framework bulk insulation to slow down the transfer of heat by conduction. These sealed panels include floor, external walls and roof cavity. Then all that is needed is the correct inclusion of mechanical vents to control the direct of airflow. You cannot have no airflow as this causes sick building syndrome and you need to remove the warm wet air so that you do not get moisture build up.
