  1. What is HPC Coating?
  2. HPC is a high performance coating that is applied to acoustical melamine foam base. Our exclusive water based HPC formulation improves durability and protects the acoustical foam from dust and dirt, allowing the surface to be cleaned using a damp cloth. The HPC coating is especially appropriate for use high-traffic areas. HPC Premium extends the HPC coating further by offering a line of brilliant colors from which to choose.

Customer Reviews

3 reviews for Sonex® Contour Panel

  1. Verified Customer

    Wonderful addition to a performance space — just the right amount of dampening. On a ceiling at 11 feet, looks beautiful.

  2. Verified Customer

    Used on the reception area of an Animal Hospital ceiling, look amazing and do even better at quieting the room.

  3. Verified Customer

    used on a ceiling. the panels are irregular and installing them directly in contact with each other is a mistake. it should also be noted that the part where they are supposed to be installed into a climate controlled environment 60 degrees 40% relative humidity should not be in the fine print.
