That's principle. If we are able to develop a dwelling to Passivhaus criteria of airtightness, and if we put in R-60 ceiling insulation, the functionality of our home will be near that theoretical scenario.
You are in a tough place, for the reason that your ductwork and furnaces are located in the incorrect spot -- outside of your home's thermal envelope.
Once the attic stays incredibly hot It appears to me sooner or later the insulation gets thoroughly heated and transfers that warmth into the living Area, albeit slowly but surely.
You've some valid details, however it is wrong to dismiss the phenomenon of HVAC devices with ductwork located in unconditioned attics. In Texas where I Stay this is the virtually ubiquitous apply. If we set in in excess of a particular amount of insulation, it will turn out to be impossible to utilize the attic for storage, as well as to walk properly for the AC for service.
The molecules in an item don't know with regards to the proximities of other matter all over them and whether or not it really is cooler or hotter in relation to them, all they know is they have Electrical power ('temperature') and among the organic things objects with Vitality do is bit by bit launch that Power by means of radiation.
Heat movement could be slowed although not stopped. Just how we evaluate heat movement via a developing assembly is by lab exams. These Garage door insulation lab exams establish the making assembly's U-variable or R-value. The reduce the U-component and the upper the R-value, the better the creating assembly is at slowing down heat stream.
To ascertain if you need much more insulation, measure what’s in place having a ruler or tape. The chart incorporated below shows you the approximate thickness of every style of insulation you need to Preferably have during the attic.
Most insulated garage doors do not have vents, and that's for a great motive.

The very best surface is blistering hot in the event the Solar's out nevertheless Within the garage you are able to feel no heat radiating down within the roof as you would probably In the event the foil/bubble/foil was not there.
three. You wrote, "With no radiant barrier, your roof radiates solar created warmth for the insulation underneath it. The insulation absorbs the heat, and gradually transfers it to the fabric it touches, principally the ceiling. This heat transfer make your air situation operate extended and consumes far more Vitality." You're suitable that plywood or OSB roof sheathing can radiate heat to the top of your insulation on your attic ground. On the other hand, your implication that the attic insulation doesn't slow warmth transfer is mistaken.
