Not only is definitely the envelope sealing a thought, but of course so is our scorching and humid Houston climate Plus the significance that you simply counsel us to hit the rafter boards with foam to reduce thermal bridging.
3. You wrote, "Without radiant barrier, your roof radiates photo voltaic generated warmth into the insulation under it. The insulation absorbs the warmth, and steadily transfers it to the material it touches, principally the ceiling. This warmth transfer make your air problem operate lengthier and consumes far more Vitality." You happen to be suitable that plywood or OSB roof sheathing can radiate warmth to the highest of your insulation on your attic floor.

Fantastic write-up Martin. About my spot, Hilton Head Island, SC, there are actually radiant barriers remaining sold for $1.fifty sq. ft. set up.

Over time I have listened to and read opinions from setting up pros, consultants and advisors. Even though perfectly which means of their need to layout and Establish Vitality economical properties, they totally misunderstand the character of heat get or loss within a developing. R-values and mass insulation is now their Holy Grail regarding how to repair the condition of heat attain or reduction. In a comparatively well-sealed interior, heat achieve or loss normally takes area between the real difference in the interior air temperature and the surface area temperature of the interior envelope on the building to include ceilings, partitions, Home windows and doors. (Heat area temperatures radiate warmth into the inside air House, Cold surface area temperatures perform heat within the the interior air Room) The inside envelope (drywall, wood, steel, glass, etc) temperature is largely impacted by the temperature in the setting up materials in connection with the exterior envelope along with the temperature of air House in between the outside and interior envelope.
