Tim writes from Kitchener, Ontario, Canada: "I am putting a metal siding on to the following wall assembly:
 1/2 gwb
 6" steel stud
 3" sprayed poly-U
 1" codeboard

In order to get the metal siding to stand proud of the masonry veneer wall below we need to install 3" 'Z' girts over the Codebord® add generic. My question is: Is there enough compressive strength in the Codebord® add generic to allow for sufficient resistance against wind loading when the girt is fastened to the steel stud through the Codebord® add generic?"

Answer: I can't evaluate the overall strength of the system you are proposing but I can tell you the compressive strength of Owens Corning Codebord® add generic available in Canada is 20.
