This insulation, manufactured using no-added formaldehyde binder, provides superior sound absorbency and fire protection that contribute to the overall comfort and safety of occupants. AFB® evo is an optimized solution for architects, specifiers, contractors and building owners interested in pursuing superior green building standards and requirements.  \nAFB® evo offers increased density that reduces sound transmission. Greater noise control is further achieved when AFB® is part of the wall assembly along with gypsum boards and resilient channels.  \nAFB® evo is noncombustible and will not develop toxic smoke or promote flame spread, even when directly exposed to fire. AFB® evo comes in a number of thicknesses to meet the requirements of both retrofit and new construction applications.  \nLearn more at [rockwool.com/afb](rockwool.com/afb)  \nGreener building  \nROCKWOOL AFB® evo is UL Validated as Formaldehyde Free and has a Red List Free Declare label.  \nAFB® evo  \nAcoustical fire batt insulation  \nTechnical data sheet  \nBatt Insulation 07210 & 09820* • Blanket Insulation 07 21 16** Acoustical Blanket Insulation 09 81 16**  \nROCKWOOL AFB® evo is a no added formaldehyde stone wool batt insulation for interior partition walls and floor/ ceiling installations in commercial constructions where superior fire resistance and acoustical performance is required.
