Cavaraf is an acoustic facility for a Parisian basement. Small accordion pads made of triple-layered recycled carpet are riveted and hooked to the vault by a network of metal ringsfixed in the stone. The absorbing pads are spaced from the vault and let the stone ventilate.
This installation, entirely demountable by the user, is interchangeable and compressible. It can undertake different patterns as it can leave the vault totally free.
