James Hardie Horizontal Steel Furring Strips

rockies63 | Posted in General Questions on

I just discovered these.
A lot of people have asked questions about using wood furring strips under their wall claddings in order to create a vented rainscreen and whether the wood strips could be vulnerable in a wildfire situation (embers blowing up into the rainscreen gap and setting the furring strip on fire).
There are metal hat channels you could use but then other people wondered what they could use if their siding was installed vertically (the furring strip would be horizontal and block the water drainage path).
These steel furring strips are perforated so that moisture can run through. I’m guessing they could also be run vertically.

And no, I do not work for James Hardie.

    Those look really useful. Our code doesn't allow horizontal furring unless there is a vertical drainage plane against the sheathing. Those solve that problem.

    I guess one drawback is the cladding needs to be secured by screws.
