I've lived in both North Carolina and Minnesota. I installed a radiant barrier in North Carolina and was very impressed by the results. Now in Minnesota there are only about two months that are hot…Continue
"It is a lovely video -- but I think you should say something about the dangers that come (i.e., backdrafting) with sealing the downstairs first. Just a thought. I like your use of those bowls and colanders!"
"Nice Video. Probably helps people understand stack losses come from both up and down.
Not sure I'd prioritize up over down. I view them as the same job. If they were 2 separate jobs I'd probably attempt to…"
"A good wall system has the weather barrier, insulation, thermal-mass, interior finish.
Existing systems are missing the thermal-mass, calculated by thickness and transmittivity to hold heat-cold long enough to reduce energy inputs, easy to sim…"
"If you reflect back to the interior of the home it will reduce the loss-rate by some amount, if you have a datasheet it's usually there how to compute heat-transfer per hour, most have the spectral breakout."
"I doubt you would see much benefit from a barrier in MN. From my research only the far southern states get much benefit but even then they need to focus on air sealing and having high levels of insulation.
The priorities in a home should be…"
