Plaza acoustic ceiling tiles are designed with a straight edge for installation in an exposed T-grid, ensuring a highly robust suspended ceiling. Plaza ceiling tiles with Unity 3 perforation achieve up to Class A sound absorption and are classified as impact resistant acoustic ceilings, ideal for areas with robustness requirements such as within the education sector, and areas with security requirements such as showrooms. The perforated ceiling tiles are made from gypsum, providing easy access to services in the ceiling void, quick fitting of fixtures, and a long service life thanks to the durability and sustainability of the sound absorbing material.
