One form of acoustic plasterboard consists of perforated gypsum plasterboard, which may be backed with a 100 mm glass wool sound-absorbing felt.

The structure is in masonry. The external walls consist of an outer layer of façade stone and an internal layer of aerated concrete blocks, with a thermal insulation layer in between. The roof is flat, and is made of reticular beams, OSB (Oriented Strand Board) panels and 41 cm of paper wool insulation. The inner side of the flat roof is finished with an acoustic plaster ceiling. The internal partitions are in aerated concrete blocks and have a thickness of 10 cm. The ground slab is in concrete, with 32 cm of EPS and a wooden floor.
