Noticed this polyester insulation at Lowe's this weekend. About 50 bucks for 6 , R19 bats , 6 1/4" thick. Unfortunately it seems to be too new to have had acoustic tests posted for it on the website. Nonetheless, might have low-irritant acoustics potential. The density seems to be just about the same as regular fiberglass batts, fairly low. But if a foot thick..... hmmmm i wonder?
New Insulation

I had a look at the site and couldn't even find an MSDS! Without any sound test data to provide some form of reference to its acoustic properties, it is impossible to say. IF it is similar standard insulation then 12" should give flat random incidence absorption down to 50 Hertz.
Where did you find the density?
Intrigued,
Andre
Andre you are correct. They have posted basically no literature on this product. I have no idea what the density is other than what it felt/ looked like as i held it in my fingers, which, is worth nothing other than a vague idea.
It seems that its only in the test market phase and might not be available nationally yet .
sorry that i have no answers. maybe time will tell, just thought id throw it out there!
as always, when in doubt go with the standard tested materials.
It is, as you wrote, a test marketing product. You are providing information about it on the ground floor! There is a duality in acoustics. Individuals spending their own money are quite willing to try untested methods. Professionals are afraid to recommend anything that has not been tested and proven. :D Please keep us updated on more information as you find it. Learning, Andrei have no answers. maybe time will tell, just thought id throw it out there! as always, when in doubt go with the standard tested materials.
Andre is (as usual/often) correct.
Yet there is some analogy with thermal isolation. Thermal isolation, based on whatever fibrous material, also needs gasflow resistance in order to prevent convection and resulting heat transport in and through the material.
This property is the basis of acoustic absorption as well.
But still, Andre's comments are very valid.
It reads to be just a simple itch free replacement for typical insulation?
"SAFETOUCH™ Fiberglass-Free Insulation has the same insulating properties as fiberglass-based products, with batts available in both R-13 and R-19."
