Sound absorption alone is not always the answer to solve acoustical problems. Sometimes sound transmission through building components is the real issue. Pinta acoustic has products for this type of application. Prospec barrier and Prospec Decibel Drop help to stop sound transmission through walls and ceilings.
SOUND ISOLATION and absorption combined in a powerful panel is another option that is well suited for special applications such as noise enclosures. This Pinta product is designed to improve SOUND ISOLATION, contain noise and minimize sound transmission and is the ideal all-rounder in room acoustics.
