Acoustic Ceiling Tile

Often found in commercial spaces, acoustic ceiling tiles (ACT) are used to soften, block, and diffuse sound.⁴ In order to achieve these acoustical qualities, ACTs are traditionally composed of fiberglass or mineral wool and natural fillers such as cellulose, calcium carbonate, and perlite.¹ Many fiberglass and mineral fiber ceiling panels use formaldehyde, a carcinogen and respiratory irritant, as a binding agent. Other ceiling tiles may contain hormone-disrupting PVC, chemical flame retardants, and antimicrobial treatments.⁷

Mineral wool can often become airborne after breaking off, consequently causing health problems associated with its binding agents. ⁵ Fiberglass particles can cause irritation to the eyes, skin, and respiratory tract when exposed.⁶ If flame retardants are used in either of the ceiling tiles, they may pose additional health concerns such cancer, hormone disruption, and decreased fertility.⁷

Since acoustic ceiling tiles are made of porous materials, they can also harbor mold, fungi, and bacteria associated with asthma, bronchitis, sinus problems, as well as respiratory infections.² A high-quality ventilation system and humidity control is crucial in preventing mold growth and is preferred over antimicrobial treatments which pose a variety of health concerns.
