The Knauf KR94TAK is an R-13 fiberglass batt roll for 2x4 wall cavities at 16-inch on-center framing. It uses a formaldehyde-free binder and carries Asthma and Allergy Friendly certification plus Verified Healthier Air status, which few fiberglass batts claim. It suits exterior walls, interior partitions and floor assemblies in new builds and retrofits. Against standard R-13 batts it competes on low dust and low VOC emissions rather than on thermal performance, where R-13 is the baseline for 2x4 walls.
