What is a class B?

Asked by Tiff October 19, 2018

Kraft facing is not rated as Class B. The term Class B when referring to a product in ASTM C665 means that a product will have a flame propagation resistance or critical radian flux of 0.12 W/cm2 or greater. For an EcoBatt Insulation this would have to be a standard foil facing. Kraft faced EcoBatts are Class C which means they are not rated for flame propagation and cannot be used in exposed applications. Kraft facing is a Type II vapor retarder meaning that it has a perm of 1 or less in case the reference to Class B was mistakenly applied to type of vapor retarder.

I have purchased 3 bags of this product to use in my historic home make-over. I have found that many of the bats in each bag have the kraft paper glued off-center by 3/4" to 1", which leaves as little as 1/4" to staple to the stud. Normal application would allow stapling two adjacent insulation bays to be stapled with one stapling run. Pulling the paper over to staple it, reveals a kraft paper that is thinner, thus weaker than other brands, which then either tears off, or pulls away from the batt. This is annoying and does not speak to a quality product, for the fairly steep price that is paid. If I were working with this on a commercial site, accommodating this defect would cost extra time/money, or would result in a lower quality vapor-barrier and work! On the up-side, I like, very much, that this material is far less itchy to work with than the pink product.

We will report this to our Operations group regarding the staple flange. If you could reach out to me so I may determine which store this was purchased at, that would be very helpful. 517-630-2076. KnaufInsulation
