Interior Acoustical Panels

Direct-Attached Interior Ceiling Panels Select TAG to import BIM product files.

Tectum Direct-Attached Ceiling Panels create a monolithic appearance without the use of ceiling grid. They combine a unique textured look with superior abuse resistance. These high-impact acoustical panels combine several functions that truly set them apart for use in commercial, institutional, recreational and industrial buildings.

Tectum panels can be mechanically attached to a variety of ceiling substrates which include: the underside of the roof deck; the joists and other support members; drywall suspension systems; metal and wood furring structures and other commonly used support systems. Panels should be no greater than 96” long, beveled on all four sides and placed in a random ashlars pattern (cinder block style). They can be cut easily and shaped with standard woodworking tools.

Tectum Direct-Attached Ceiling Panels can be used in their attractive unpainted natural color, painted white or custom colors. Also, these panels may be painted or re-painted in the field up to six times without reducing their acoustical properties.

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.

Installation Instructions


ASTM E-84 - Flame Spread/Smoke Developed

Tectum Interior Ceiling Panels - 0 Flame Spread, 0 Smoke Developed


Tectum Direct-Attached Ceiling Panels are available in 23¾" and 47¾" widths and lengths from 2' to 8' in one-inch increments. Tectum Direct-Attached Ceiling Panels are available in natural, painted white or custom colors, and can easily be field painted up to six times without losing their acoustical efficiency.


  • 1" - 1.65 lbs./square foot

  • 1½" - 2.55 lbs./square foot

  • 2" - 3.50 lbs./square foot


  • 1.75 per inch of thicknes
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.
