4sound® is the ideal sound absorbing panel for any private or public interior where acoustic comfort is required. Hotels, restaurants, gyms, shops, theatres, places of worship, auditoria, concert halls, music schools or home theatres all achieve the wished-for acoustic quality with 4sound®.
4sound® is a system of sound absorbing wall and ceiling panelling consisting of staved MDF panels with horizontal milled grooves in the top face and holes in the underside which create Helmholtz resonators. The types available differ in the size of the mills (2 or 3 mm) and their spacing (8, 16, or 32 mm) P08F02 – P16F02 – P16F03 – P32F03. Different mill layouts deliver different acoustic performances. 4sound® is available in any surface finish, from melamine to RAL lacquered and from plastic laminates to wood veneers and composites.
Panels are available with Eurocode “B-s1,d0” reaction to fire and CE marking for construction materials.
