Roof cross section

How it Works
Similar to the wall panel, this panel creates, when it is sandwiched between two surfaces such as the roof decking and the roof cover, a continuous air gap. In order to construct an air gap, the present method requires the use of vertical furring strips, which result in horizontally-placed barriers to the rising hot air, confining it to an upward direction only.
When you sandwich these panels between roof-deckings the open venting channels will create a convection current. This allows passive roof ventilation to occur. The convection current has the added advantage of substantially cooling the interior temperatures.
​
As can be seen in the diagram, with the addition of a heat exchange unit at the apex of the roof, the hot air can be reused to heat water, or to drive A/C within the home etc.
