Which steel stud system would you select if you were concerned about mold, condensation or corrosion? System #1 or System #2? The informed owner would select system #2.

THERMADRAIN can be used in any drainage wall configuration, including CMU back-up or metal stud wall applications. Thermadrain comes in 16" x 96" (cavity cut) or 48" x 96" panels. Our exclusive cavity cut makes installation between the wall ties easy! Available in 1 3/8", 1 7/8", 2 3/8" and 2 7/8" sizes.
