Our take on the Knauf Ecoroll R-19 Unfaced Fiberglass Insulation Roll 6.25 in x 15 in x 39.2 ft

Knauf EcoRoll R-19 is an unfaced glass mineral wool roll for 2x6 wall and floor cavities, sold as a 6.25 in x 15 in x 39.2 ft roll covering about 49 sq ft. Its ECOSE binder is formaldehyde-free, GREENGUARD Gold certified and made with at least 50% post-consumer recycled content, and the batts are softer and less itchy than older fiberglass. R-19 suits exterior 2x6 walls and sound control between floors; against faced batts it lacks a vapor retarder, so it needs a separate membrane where code requires one. Owners of mineral wool and fiberglass batts generally rate it for easy cutting and low dust, though it still calls for gloves and a mask.

Questions and answers

What R-value is this insulation?
R-19, sized for 2x6 framing. It is not meant for 2x4 walls, where it would be compressed.
Does it have a vapor barrier?
No. It is unfaced, so a separate vapor retarder is needed where local code requires one.
How much does one roll cover?
About 49 sq ft at 15 in wide and 6.25 in thick.
Is it safe for people sensitive to formaldehyde?
The ECOSE binder is formaldehyde-free and GREENGUARD Gold certified, which is why some buyers choose it.
Can I use it for soundproofing interior walls?
Yes. It absorbs sound well between floors and in walls around bathrooms, kitchens and bedrooms.
Does it need special tools?
A utility knife, straightedge and gloves are enough; it cuts and tears by hand.
