Our AlphaSorb® Pyramid Foam sheets reduce echo and reverberation to improve speech intelligibility while providing a unique architectural appearance. The unique pyramid geometry provides exceptional acoustical performance and sparks immediate visual interest. AlphaSorb® Pyramid Foam create a visually-pleasing, acoustically enhanced environment, greatly improving speech intelligibility thus promoting a comfortable acoustical profile within the space.
Pyramid Acoustic Foam gives you one uniform look to a treated wall and is ideal for any application where sound absorption and aesthetics are both considerations. AlphaSorb® Pyramid Foam is available in natural grey and white colors or painted with a non-bridging paint. Available 2″, 3″ or 4″ thicknesses, AlphaSorb® Pyramid Foam panels easily mount direct to walls or ceilings with a general foam construction adhesive.
