Text in section 16.3 states:
Where the veneer is attached to the wood wall by corrugated sheet metal ties, the air gap separating the veneer from the wall should not be more than 1 inch. Each tie should be spaced no more than 24 inches on-center horizontally and vertically. Each tie should support no more than about 3 square feet of wall area.
The graphic directly below states: “minimum air space 1"”
Common sense says that the maximum is 1", but I don’t want to assume. Which is it?:?:
Chad,
Thank you!
This has been corrected. There’s overwhelming opinion, including code and building science, that suggests a recommended minimum air space of 1 inch. The air space should not be less than one inch. Considering an 8-inch concrete block, you have 3 and 1/2 inches for the brick, 3 and 1/2 inches for the stud and an air gap of about 1 inch.
The phrase “should not be more than” has been changed to “should not be less than.”
Thank you.
Iron sharpens iron.
