I just read this summary of some studies they did, and apparently they've been able to prove that there is no difference in performance between insulations, and that no insulation has any effect on air leakage, or derives improved performance from it.

Opinions? Do you guys feel this is accurate or correct?

From my knowledge, cellulose and fiber glass batts do not offer any protection against air infiltration. But spray polyurethane foam insulation does. Only one study in the former article had mentioned spray foam insulation, and it is fairly outdated, having been done over 10 years ago. If you'd like, I can find some more recent articles that talk about the benefits of spray foam insulation and its ability to stop air infiltration.

More important is the fact that NAIMA is still sticking to this study. It is publishing the "findings" as part of their handout fact sheet.

What do you think of this practice? Why would they be telling people that there's no difference in insulations?

NAIMA is the mouthpiece for the fiberglass industry and does everything it can to hide the fact that cellulose and foam are better than fiberglass. Fiberglass is a waste of money it does more harm than good.

I see you are into green building.

Thats awesome, do you have clients that want it or are you just breaking into that field?

I just sell the benefits to the families and health reasons, financial reasons, and comfort reasons. Green or enviromentally friendly is the last thing I push on them.

For the most part I find that no companies are really in the business for the green aspect. Truly sustainable companies cannot compete in the US market.



Most companies just have someone in their organization that realized there was a green benefit buried somewhere in their product, and the marketing department was issued the task of glorifying it.
