Parafon Buller Solid is an effective, impact-resistant sound absorber for ceilings and walls in environments with lower aesthetic requirements, as some irregularities and colour variations may occur in the product. The Buller Solid features a reinforced fibreglass fabric surface that can withstand impacts and rough treatment, and is suitable for use in locations such as heated cellar spaces, industrial facilities and sports halls. Parafon Buller Solid features a non-combustible stone wool core that retains its shape even at very high temperatures if exposed to fire, as well as having good climate properties.
