Wood fiber or wood wool acoustical panels are made primarily of shredded wood and a cement-type binder. The binder may be Portland cement or magnesium oxide-based. Because of the specific fiber dimensions needed to provide the desired structure and acoustic performance, recycled wood is not used for these products. Wood fiber acoustic panels provide an NRC rating of 0.4-1.0 depending on the specific product and the mounting method. Panels can be used on walls or ceilings, and installation options include direct attach (with mechanical fasteners or adhesive), lay-in, tegular, clouds, and baffles. Products can be unfinished, clear-finished, primed, or painted. This Common Product considers panels that are factory primed and painted white. See the All Contents for pigments that may be used in paints for a range of colors. While not common, some products may include an optional fleece backer to improve acoustic performance. Information on potential contents of this backer is included in the All Contents.
This is not necessarily representative of all possible content that may be found in this product type. It includes all of the potential content identified during the research process for this Common Product profile. All Content data goes beyond the most common chemicals and materials to provide a more comprehensive representation of what may be found in specific product types. It does not necessarily include all chemicals and materials that may be used by all manufacturers and should not be used as a replacement for a specific manufacturer's product disclosure.
About Process Chemistry
Pharos process chemistry does not necessarily represent all chemicals that may be
used in the production of a chemical or material and may list chemicals that are not
used in all manufacturers' processes. We recommend using Pharos process chemistry as a
starting point in conversations with product manufacturers and chemical suppliers to
determine process chemicals that are relevant to specific products, including known
and potential impurities and residuals. For more information see the
Pharos system description.

What are Common Products?
A Common Product profile (CP) is a list of substances that are most commonly present in a product type (vinyl composition tile, for example) as delivered to building sites in North America. The profiles are not specific to any manufacturer.
CPs are organized by chemical function. Every substance in a product performs some function - for example, it thickens a paint, or gives a carpet resistance to stains. The CPs provide the most common substance serving each function in a given product type, the hazards these substances carry into a building project, and a general description of the product type. CPs are based upon a wide range of publicly available information, including product declarations, patents, and chemical suppliers' brochures that detail the functional uses of various additives.
For those wanting more than the most common chemical for each function, Pharos subscriptions provide access to the full catalog of possible ingredients that we’ve found may be in products. Where available, these are displayed in the All Contents tab.
The GreenScreen® for Safer Chemicals™ is a benchmarking system to rank the safety of chemicals on a 4 point hazard scale and encourage progress toward safer alternatives. Chemicals that have undergone a full GreenScreen® Assessment™ by Licensed GreenScreen Profilers are given a GreenScreen Benchmark™ score, which is the most authoritative. Chemicals that have been screened using an automated comparison to hazard lists are given a GreenScreen List Translator™ score, which is less authoritative. Full GreenScreen Assessments trump results from List Translator scoring.
GreenScreen scores in order from highest concern to lowest concern are:
