I’ve heard over and over that james hardie doesn’t warranty against rain-screen installations, but then why do they recommend a rain-screen in their European installation guide, except here they call it a ventilation gap. See below:

2.2.2. Ventilation Gap
A ventilation gap should be provided between the cladding
layer and substrate. Suitable care should be taken to prevent
insects and pests entering through the ventilation gap – install
a suitable ventilation grill, corrosion resistant wire mesh or
similar.

Why is this? Is it become in Europe rain-screen applications are so common and developers know how to properly install this product?? Or does it have something to do w/ the lesser litigation in Europe that Hardie feels less exposed when recommending this installation method? I did notice that hardie only warranties the product for 10yrs vs. 50yrs in the U.S. , which maybe has something to do with it.

I’d be happy with even a 10yr warranty instead of no warranty, but am I asking for too much?

    As long as the fastening schedules and building codes are followed James Hardy will
    warrant their product. They will not warrant the installation.
