What Are The Benefits?


The Acousti-Slab is a versatile solution for your acoustic treatment needs. These panels can be easily trimmed and cut to size, offering endless customization possibilities. You have the freedom to wrap them in your own open-weave cloth, creating fabric-wrapped acoustic panels that match your studio's aesthetic. Alternatively, you can leave them as is and mount them directly to your walls or ceiling, ensuring effective sound absorption.

By strategically placing these acoustic foam panels at first reflection points and other critical areas, you'll experience enhanced acoustic clarity and a reduction in unwanted distortion. Our panels excel at controlling mid to high frequencies, effectively minimizing echo and reverberation. Additionally, these panels can be seamlessly integrated with our other acoustic solutions, allowing you to create a unique and visually appealing design while maintaining excellent acoustic performance.

At Advanced Acoustics, we prioritize durability. Our foam panels are designed to withstand the test of time, avoiding crumbling or colour deterioration once installed. We meticulously optimize the panel's size, profile, foam cell structure, and density to deliver a product that offers both exceptional acoustic performance and aesthetic appeal.

    Performance Data

    4" Acousti-Slab Acoustic Foam Panel

    Installing our acoustic foam panels is very simple. The first step to take is to work out your preferred layout of acoustic panels. Do a sketch on paper first to make sure that the layout looks right and you have enough acoustic foam and space for your planned design.

    Once the acoustic panels are mounted to the wall or ceiling they are hard to remove so it is important to get the layout right before you begin. Once you have a sketch of the layout you plan you can then mark up the wall with the layout. You can either use pencil, masking tape or lasers to layout the design on the wall or ceiling.

    When mounting the acoustic panels to the wall apply Advanced Acoustics Contact Adhesive to both the back of the panel and the mounting surface. There is no need to heavily cover the acoustic foam or wall with adhesive, a band of adhesive around the perimeter of the tile along with 50% - 75% coverage of the rest of the acoustic panel will be fine. Use the same equivalent amount on the wall. Avoid overspray on the tile and the wall so that adhesive can’t be seen when the panels are in place. Masking Tape on the wall will help with this. If you do get webbing overspray on the foam panel, don’t touch it, allow it to dry, in most cases you will be able to peel the adhesive off.

    The adhesive we supply is solvent based so we recommend that you keep all doors of the room and any windows open whilst completing the installation.

    If you prefer to have a more temporary installation of acoustic panels there is the option to have the panels pre-mounted onto 6mm MDF. This will enable you to hang the panels on the wall using a D-Ring (not supplied) and picture hook for a damage free installation. If fitting them to a ceiling then 4 mirror plates (not supplied) would be required.
