Best Type of Furring Strip for Vertical Metal Cladding
Hello, my wife and I are planning on building a custom steel home this year. Our wall assembly (From outside to inside) consists of; 24 guage metal cladding with hidden fasteners installed vertically, furring strips installed over 1″ XPS with taped and sealed joints (…to act as a rainscreen and air gap) both directly to the steel wail girts and/or steel framing members, (The XPS will be fastened with Trufast Thermal Prong washers), the wall cavity will be filled with 8″ mineral wool insulation without a vapor retarder (…due to the hot and humid climate in Houston TX), 1/2″ painted drywall.
We are trying to determine which type of furring strips would be the most economical and functional for this type of application. We see that most furring strips are installed horizontally when installing vertical siding; however, this seems to cause a water dam effect in a way. Wouldn’t it make more sense to use a furring strip that is vented? And then, if it is vented, which type of strip would be best so that you don’t have a compression issue when you install the metal siding?
Any advice on this subject would be greatly appreciated.
