Sound Absorbing Acoustic Wall Panel

BRUCHAPaneel® WP-A

Brucha’s WP-A panel (Wall Panel – Acoustic) is the sound absorbing version of our WP-F (Wall Panel – Fire Rated) mineral wool insulated panel. This panel is used for exterior walls*, interior walls/liner panels and ceilings and helps reduce ambient noise levels by absorbing rather than reflecting sound. Industrial facilities with loud equipment such as power generation or manufacturing plants are ideal applications for this product. The mineral wool core not only provides excellent sound deadening but is also non-combustible. The panels come standard with a protective film at panel sidejoints, protecting the core from unwanted moisture.

Available in six different profiles and 10 different thicknesses, WP-A provides the solution to a variety of design challenges.
