Acoustical Ceilings

Metal ceiling panels are available in non-perforated and perforated varieties. Non-perforated panels offer little in terms of acoustical properties and as a result are generally used in instances where other features, for example ease of cleaning or a high degree of light reflectance, are predominant factors. To achieve good acoustics (sound absorption), a perforated aluminum panel with an open area of 15 to 20 percent, together with a black acoustical fleece (SoundTex®), could produce an NRC (Noise Reduction Coefficient) of 0.70 or higher. For areas that require either increased NRC values or a higher degree of sound blocking (typically referred to as STC or Sound Transmission Class), SoundTex® used in combination with a fibreglass matt should be used for optimum sound absorption.
