When thinking about sustainable design, acoustics probably don’t come to mind, but depending on the build type, dampening noise pollution may be an important part of the brief. Taking this into consideration, Knauf has developed Stratopanel, an acoustic ceiling lining with built-in air purifying CLEANEO Technology. According to Knauf, used in the company’s perforated acoustic plasterboard range, the technology reduces both smells and airborne pollutants such as VOCs, improving overall air quality.
