The cavity (5) between the plates is filled with rubber particles. #CMT#USE : #/CMT# For outdoor use, e.g. to form walls for cutting out noise from roads, trains and aircraft. #CMT#ADVANTAGE : #/CMT# Thinner walls can be constructed compared to concrete barriers. The wall panels have a long working life outdoors. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a perspective view of the wall panel. 1 : wall panel 2a : skin plate 4 : spacer 5 : cavity.</p> |
