COURTWALL® Full and Half System 4.0 - with silica sand refill
The surface of the finished walls in both 4.0 systems have several coats of paint, and both 4.0 system walls are filled with kiln dried sand to minimize the ball impact sound and are designed for all humidity levels.
The COURTWALL® 4.0 Full System walls have a total thickness of 94mm, consisting of two 21 mm thick high-density wood boards, creating a cavity by use of distance steel profiles. The COURTWALL® 4.0 Full System is free stan-ding and self-supporting.
The COURTWALL® 4.0 Half System is used where in projects existing and usable flat solid building walls can be used to attach the play wall system on steel rails.
