Drainage Media

You are here: Home / Drainage Media

Drainage media has been used behind Master Wall® Systems for many years.  The drainage media can vary from a very thin cross section material, a thicker version designed to prevent capillary action to a true ventilated wall cavity.  The designs will vary and Master Wall® is available to help coordinate detailing as needed.
