A prime function of a metal ceiling is the creation of a pleasant room environment via intelligent noise abatement. Armstrong perforations offer an extensive spectrum of aesthetic solutions for effective acoustic comfort.
Perforation and light reflectance The brighter a ceiling surface is, the better its reflectance. A small overall proportion of perforated surface will result in a high reflectance. As an example, ceilings using ultramicro® perforation Rg 0501 where only 0.64% of the total surface area is perforated will require significantly less illumination wattage than other types of perforation.
