fonosphera® SF51

thermoforming solution

fonosphera® SF51 consists of a body of material with a low mechanical modulus made of a polymer base and mineral filler additive laminated to a layer of polyethylene with spherical cap structure.

The material used in fonosphera® SF51 is studied to provide not only a high level of sound insulation, but also class 1 fire reactivity.
fonosphera® manifests a "spring effect" when laminated to rigid panels, which optimises sound 
insulation performance.

fonosphera® SF51 is C-s2, d0 fire certified (Euroclass UNI EN 13501-1 2007).

The product is lightweight and slim and contains no additional adhesives which can cause the product to deteriorate over time.

fonosphera® SF51 is particularly suitable for airborne sound insulation and vibration damping in metal and fibreglass structures, plastic laminates, plywood and masonry.

fonosphera® SF51 is supplied in 1 x 10 metre rolls, also available with adhesive.
