Knauf Performance+ is built for retrofit.

Insulation isn’t installed in a lab. It’s put in 130-degree attics, cramped crawlspaces, and tight wall cavities. The material you choose either makes that job easier or harder. Performance+ with ECOSE® Technology is made without added formaldehyde, engineered for low-dust and reduced airborne fiber release during installation, and is built for consistent quality across many applications. That’s fewer callbacks, faster inspections, and a job site your crew wants to show up to.
