A MULTIWALL SHEET AND METHODS FOR APPLYING SAID SHEET

摘要

A multiwall sheet can comprise plastic walls, wherein the walls comprise a first wall; a second wall; and a transverse wall, wherein the first wall, the second wall, and the transverse wall extend longitudinally; and a rib extending between adjacent walls; and a sound insulating material disposed in an area between two adjacent walls, wherein the sound insulating material has a velocity of sound greater than the velocity of sound of the plastic walls. A method of sound insulating a structure can comprise: filling the multiwall sheet with a sound insulating material; and attaching the multiwall sheet to the structure.
