I will soon be getting roof insulation in my roof space to reduce the unbearable heat in the upper rooms. I already have silver foil under the tiles however this is not sufficient. To supplement this I am also considering some additional upgrades.
1. Roof extractor - Has anyone seen or considered the following solar powered roof extractor in lieu of a whirly bird roof extractor http://www.solarwhiz.com.au/solar-whiz-products/
2. Installing heat reflecting window film to windows on the west side, I have tried the commercial stuff from HomePro and find it useless.
3. Installing window awnings, only problem is access for the upper floor.
