This is exactly why I pointed out that "there isn’t any have to have to install a radiant barrier in the effectively-built residence." I also identified that if your builder designed the unfortunate determination To place HVAC tools or ducts in your attic, then you had improved set up radiant-barrier roof sheathing.
Doing work in an attic or crawl space without the appropriate devices and understanding of the framework is harmful. Because it is just not intended like a place for people today to spend time, attics will often be made with uncovered nails and insulation, the two of that may be damaging.
But being a basic rule, we don't set HVAC machines or ducts inside our attics up north. Once i describe to someone in Texas that It can be beautifully attainable to build a household with forced-air heat and air conditioning With none ducts while in the attic, they sometimes say, "That's unachievable," or "Which is not likely to occur in Texas."

Superior discussion of this. I myself went to your cost-free supper to hear the pitch this summer months, and was in the position to steer a couple friends far from paying out $1.50/sf. One particular particular person purchased their particular, additional more insulation and foil.
It Seems like you and I are on precisely the same page. Thanks for sticking with GBA Despite proof that we often Display screen Northern bias.
Insulation functions. Just how we measure the usefulness of insulation is by evaluating R-values. A layer Eco friendly fiberglass insulation of R-30 insulation is twice as efficient as a layer of R-fifteen insulation; it will only enable fifty percent the heat movement of the R-fifteen insulation.
In the event you’re living in a home which includes no insulation from the attic, don’t Permit One more summer season strategy with no repairing the issue.
If you stack up your foam and seal the edges to make the foam airtight, it functions like only one, vapor-impermeable sandwich. You are not on the lookout for vapor diffusion from the foam, and vapor diffusion isn't really going to occur.
