Absorbs and blocks sound

The ideal acoustical combination - ceilings that combine sound absorption and sound blocking are best used to help keep noise levels down and prevent disruption to and from adjacent spaces.

Impact resistant

These tiles are able to withstand occasional impact. Ceiling tiles with this characteristic are best used in school hallways, gymnasiums, or cafeterias.


These tiles are made from a high amount of recycled content, free from "chemicals of concern" and meet various green building standards in the US.

    Frequently asked questions

    To find replacement tiles, you will need to find the item number of your current tiles. You can do that by removing the ceiling tile and flipping it over. Once you do that, locate the item # on the back of the tile. Enter the item number on our ceiling replacement page to get your match.

    Dust and loose dirt may easily be removed by light brushing or with a vacuum cleaner. The best attachments to use are the ones for cleaning upholstery or walls. Make sure to clean in one direction only to prevent rubbing dust into the surface of the ceiling.

    After loose dust has been removed, other marks can be easily erased with an ordinary eraser. Although, a fresh wall cleaner may be preferred. 

    Mineral fiber ceilings may be cleaned with a moist cloth or a sponge dampened in water containing mild soap. The sponge should contain as little water as possible. After washing, the soapy film should be wiped off with a cloth or sponge slightly dampened in clean water.

    Look for the disinfectable and cleanable icons for more information on your specific ceiling tile. You can also download our cleaning and disinfecting guidelines for more information.

    Our Ceiling Selector can help you figure out what you need. After a few quick questions, we give you recommendations and can help you with your order and with installation.
    It is recommended to change ceiling tiles out every 10 years. We have a 10-year warranty on most ceiling tiles. You can always patch and match a few tiles in the interim to transform any space or fix damages.

    All of our mineral fiber ceiling tiles and panels can be painted with latex paints. The front and back of 24-in x 24-in and 24-in x 48-in panels should be painted.

    PLEASE NOTE: Field painting will void the warranty. We cannot guarantee that the surface-burning characteristics, fire-resistance ratings, acoustical performance, dimensional stability/sag, or light reflectance will remain the same after repainting. TECTUM tiles can be painted up to 6 times without losing acoustical performance.
