In my situation, I expended $350 in resources to take care of 1200 sq ft by stapling to the rafter undersides. I deliberately WON'T deal with the northern/shaded attic space since the return on that investment decision (less of a temp differential) can be weak.
one. I have talked into a contractor about sealing and and insulating my attic. And my reaction is similar to your's about radiant heat: it isn't cost efficient!
I might be not shiny at the rear of the air space just after mortar dropping, but appears better than almost nothing in this case and quite productive. Views everyone?
Loads of scientific studies, like scientific tests done by Danny Parker on the Florida Photo voltaic Energy Heart, too observations by persons like Curtis Dean, who just posted a comment, confirm my assertion that insulation enhancements are less expensive when compared to the installation of an attic radiant barrier within an existing residence.
A radiant barrier is usually a shiny panel or flexible membrane used in development. Despite the fact that radiant barriers haven't any R-worth, they are often made use of as Portion of a creating assembly — such as, an assembly produced up of the radiant barrier and an air space — to slow heat transfer.
The better your ceiling air barrier, plus the thicker the insulation layer on your attic floor, the closer your residence will come to the theoretical predicament you posit -- namely, the temperature with the attic is irrelevant.

As well as the passive residence motion might quite well happen to be born from the need to retain heat in colder climates. But This website (and your weblogs) do such a good task of pushing homeowners to check out strategies to use their property being a Device for Strength consciousness and conservation. After i see a 'improperly accomplishing' northern property's utility charges, it is usually fractional in comparison to the 1kWh/sq ft/month that even reasonably 'efficient' present residences in Texas eat all through peak summertime months. I've tracked my usage over the past two decades. During gentle months, we consume around a third from the energy as in peak summer months, so I am aware the HVAC running is our Most important enemy. I Individually am even more challenged Thermal barrier by acquiring only one zone inside a two story household.
It can be certainly exciting to find out how regional discrepancies in building tactics Perform out. Listed here in northern New England, It is really not unusual to set up twenty inches or more of attic insulation.

Sonobatts Insulation is an additional specialty insulation. It's meant to supply supplemental thermal and acoustical Manage when used above suspended ceilings. It is offered either unfaced or with asphalt-coated kraft experiencing on 1 facet.
