E04B2001/8414 - CPC Classification

Classification description:

Constructions in general; Structures which are not restricted either to walls, e.g. partitions, or floors or ceilings or roofs; Insulation or other protection; Elements or use of specified material therefor; Heat, sound or noise insulation, absorption, or reflection . Other building methods affording favourable thermal or acoustical conditions, e.g. accumulating of heat within walls specifically with respect to sound only; Sound-absorbing elements with non-planar face, e.g. curved, egg-crate shaped
