Interior Acoustical Panels

Interior Ceiling Panels

Tectum Ceiling Panels combine a unique textured beauty with superior abuse resistance. These high-impact wood fiber panels combine several functions that truly set them apart for use in commercial, institutional, recreational and industrial buildings. The panels are available in a wide range of sizes. They can be cut easily and shaped with standard woodworking tools, and installed in standard grid systems or direct attached. By using Lay-In, Tonico, Multiplane, V-line and Designer Series Tectum panels, the designer can create a variety of three-dimensional patterns.

Tectum decorative and acoustical panels can take repeated abuse and still retain their appearance. Tectum Ceiling Panels have remained the product of choice for over 50 years for any area where noise is a problem and the ceilings are subject to abuse.

NRC/Mountings - Noise Reduction
Up to 1.00 NRC can be achieved depending on mounting style. Furring strips installed horizontally (when using
vertical panels) are recommended and should be a maximum of 24" o.c. when using 1"-thick panels.

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.
