"Chris, to what are you referring to as the Kool Aid?
If you are referring to cellulose then I suggest you get out in the field and blow a few attics with the best loose-fill fiberglass (something like OC L77) and cellulose (something like National…"
I have experience with both fiberglass and cellulose. I think that cellulose is better. Dr. Energy Saver on Youtube.com has a video to explain the differences. See info below.
Why Cellulose Insulation is Better than…"
"Up here In Canada Fibreglass wins hands down for heat loss!
Check back 5, 10 & 20 years later on your Cellulous blown attic spaces, in all our inspections the Cellulous had settled 300-400% in all attics, good grief in most cases we could…"
"Given your list of allergies, molds and rodents loving it, you are not using the cellulose we are discussing. You are also selling a different product that may or may not be the best for the home owner.
I know everyone sells what is on…"
"It's Me again. Sorry to swim against the flow but cellulose is a disaster. Dusty, causes allergies, asthma, molds, settles losing R-value, rodents love it, bridges when blown into existing walls, soaks moisture and on and on. Fiber glass is…"
"My experience with cellulose began when I started to participate in the state of Massachusetts' home energy programs.
Cellulose was mandated for attics and other spaces. Before this, I had only seen blown-in fiberglass in the new home…"
"Oh yeah, I'm a nerd. At big Orange store today and stopped to read Fiberglass blow in package.
And I quote
Another method of insulating your attic is our loosefill insulation. Instead of laying batts or rolls, our…"
"Hi Isaiah, Here in upstate NY we primarily use cellulose for blowing attics and dense packing sidewalls.It's cheaper, heavier, and as you noted performs better in single family residences. The one area that fiberglass works better than…"
"All things being equal & everything being done properly (air sealing, baffles, hatches) - both work fine but cellulose will win out not because of your reasons, but the simple fact that FG R-Value drops the hotter it gets.
Granted you could…"
As a rater and insulation contractor I personally respect the overall insulation properties of blown cellulose a lot more than blown fiberglass. I have taken numerous infrared images in attics with the same R-values, both products cellulose and fiberglass. I find time and time again poor performance of blown fiberglass. The R-values are similar, but cellulose is a much denser product.I was wondering others raters and contractors thought were the same on this topic?In the area I live in (…See More
