3. You wrote, "You again are incorrect a R30 vented attic will not likely outperform a unvented R20 employing foam." I don't know what paragraph, if any, you might be quoting from. I never reported any this sort of thing.

By the way, the number of several hours that attics in North Carolina are actually at -eighteen°File is close to zero, meaning that even when some idiot could discover some of that horrible free-fill fiberglass analyzed by ORNL twenty years in the past, the R-value degradation would seldom, if ever, take place.

As you already know, using Icynene will not be essential. Numerous builders are building quite tight houses without any Icynene.

Reality is not any buildings are airtight - it is a squander of cash and a burden on our Vitality safety to mandate the doubling of insulation needs for all new households when the reality is the fact that we are able to all exceed the sphere performance of R-38 fibreglass with R-twenty fibreglass and $fifty in cans of Dow Fantastic Things.

The Illinois tests on Insul-Harmless III uncovered that the average rise in heat loss through the attic over the thirty day period of January resulting from convection was about 25%.

To your extent that designers and builders have an interest in Net 50, Web thirty or Internet Zero housing, we want to be there assisting them get it done. We wish to possess the attempted and examined remedies accessible when regulatory authorities want it.

You all over again are incorrect a R30 vented attic is not going to outperform a unvented R20 applying foam especially when HVAC devices also are located in the attic and R20 of froth will most undoubtedly outperform R30 or R38 of fiberglass in the vented attic.

I'm look at this website not sure whether you are losing the homeowner's revenue or not. It will depend on what you are attempting to obtain.

Confident, knowledgeable installers would hardly ever Enable that come about, see this page but apparently People are in somewhat limited offer. As evidenced by another Frightening foam failure I've seen quite a few moments: cracked and delaminated foam.

The concern of highest thickness constraints for spray foam is challenging and sometimes dismissed by code officers. I wrote an short article about the problem to the April 2008 problem of Strength Layout Update

1st, allow me to condition for the history that I'm not a large enthusiast of spray foam insulation, as there are inexpensive approaches to accomplish equivalent air sealing and insulation overall performance in new building when just one has control of the procedure. I also agree that maker advertising and marketing buzz is often just that.

Once again, where by could be the "overall performance dilemma" when my customers are returning to me to state this kind of issues as their new house that may be 6,seven hundred square ft is using the exact same degree of energy for heating and cooling as their previous three-year-aged home which was 3200 sq ft? Or is their a "overall performance difficulty" with documented personal savings of 37% this in present households where we sprayed only the roof and crawl ceiling with six" and three" respectively (TESTIMONIAL: ). Do you think you're putting your identify at stake to state that their benefits could well be A further 37% or 50% better had I sprayed 10 inches within the roof decks? I've a letter from a V.P. of a fiberglass company, documenting sizeable cost savings of both equally fuel and electrical in a very property that was UNOCCUPIED last year and OCCUPIED this yr, but experienced the heating and cooling set to help keep it sensible for demonstrating the home very last year.

On this comment of yours: "It truly is now time and energy to suppose that ALL properties might be built with consideration to air tightness." all I'm able to say is, DAMN, you are pretty the optimist. Regretably, I believe we are still significantly from the time that all properties may have that Considerably awareness compensated to air tightness.

- air sealing to circumvent convective losses, resulting in new losses of five hundred BTU around time period X (this advancement is significant in current developing inventory resulting from latent heat)
