TX, USA – I always thought in terms of fluid dynamics when it came to heat – a fancy way of saying I wasn’t thinking clearly. Here’s a great article, and what I learned today (you should learn at least one new thing every day, and relearn three). …”In simple terms, heat travels in three ways: convection, conduction and radiation,” Reed said. “The radiant barrier blocks the radiant spectrum; additional insulation slows conduction of heat into the house, and we put in another 20 eave vents and replaced our passive spinning turbines on the roof with solar-powered vents. That solves the convection problem.” …
