Pyramid Foam

Pyramid foam is a sharp looking, but traditional acoustic treatment usually found in recording studios and spaces where reverberation needs to be controlled. Although it is part of recording tradition, the design appeal of this acoustic foam is timeless. With its laser accurate straight lines and mythologically inspiring tall cubic peaks, it is the ideal statement cladding for any modern space. With RAL and PANTONE colour matching options available, as well as fully customisable sizes, it is the perfect addition to any public or working space.

Sound Zero Pyramid foam forms part of our core range of G25 acoustic foam products that are engineered as acoustic absorbers. These products are principally designed to control reverberation by preventing sound waves from reflecting off hard surfaces.

The crisp and clean design is not only eye-catching, easy to install and elegant in every way, it is also functional. The increased surface area and relative tile thickness ensures that acoustic absorption is kept even, for a smooth, quiet and calm listening environment.

Our G25 Pyramid foam offers superior sound absorption, is proudly made in Britain and is the number one selling acoustic foam product on the market today.

Pyramid foam is precision CNC cut at our very own manufacturing facility to ensure a uniform profile all the way through. With manufacturing done in-house, we can cut Pyramid foam – or any of our acoustic foam range – to any required dimensions.

These acoustic panels provide a slick and professional finish within a range of applications, from offices to music studios, allowing for a truly versatile acoustic solution. Pyramid foam acoustic panels and tiles can easily be modified and trimmed on site, or pre-cut to a size to suit the space you are treating.

With Sound Zero’s exclusive coating system, Pyramid foam is available for specification in any Pantone or RAL colour – meaning that you or your client’s branding can be applied to create a truly unique solution.

Step 1: Prepare wall surface, ensuring it is clean and dust free
Step 2: Measure and mark your grid lines to ensure you are working in a straight line (alternatively use a laser level to mark your straight edge)
Step 3: Spray both the wall and the back of the sheet or tile with spray adhesive
Step 4: Press the tiles onto the glued wall and hold for 10-15 seconds to allow the adhesive to form a bond.
Step 5: Cut any overhanging or odd edge tiles with a long straight knife and repeat processes 3-4.
