Inner-Safe™ Concealed Space Batt Insulation
Knauf Inner-Safe Concealed Space Batt Insulation is made from inorganic, bio-soluble fiberglass; bonded using a formaldehyde free, bio-based binder. It is a non-combustible product that meets and exceeds NFPA 13 Standard requirements - saving time and money on multi-family construction projects by offering a superior alternative to sprinklers in interstitial spaces.

All Knauf Insulation products manufactured using our bio-based binder; ECOSE Technology, are formaldehyde free.
