Denim insulation is made from recycled cotton denim (post-industrial cotton fiber) and contains no irritating glass fibers. It is completely safe to handle without PPE, provides excellent acoustic performance, and is a popular choice for homeowners who prioritize indoor air quality and sustainability.
Denim batts achieve R-13 to R-21 depending on thickness. They are treated with a borate-based fire retardant and provide very good sound dampening — making them popular for media rooms, home offices, and interior partition walls in Boston-area renovations.
