Tectum Interior Wall Panels offer an effective, permanent and attractive solution for any kind of activity that produces undesirable noise levels within an enclosed space. They are abuse-resistant and are able to withstand repeated impact, yet are lightweight. Tectum Interior Wall Panels are easy to install in new construction and in existing buildings for effective sound control.

Light Reflectance


Tectum ceiling and wall panel measurements are plus or minus 1/8 - 1/4". Thicknesses are nominal. Panels that are to be butted must be beveled and will require field fitting or molding can be used to cover edges.


Tectum Acoustical Panels can be used over swimming pools and in open construction such as breezeways and open garages. They should not be installed where they will come in direct contact with water or condensation. Reveal edge panels (Tonico) should not be used for this purpose.

1" panels should not be used where the relative humidity will exceed 85%. Panels 1½" or thicker are not restricted by humidity conditions.

In all cases, the plenum must provide cross-ventilation to prevent condensation.
