Looking for Hardie panel rainscreen experience
I’m planning on using hardie panels to create a rainscreen system for my cladding as follows:
2″ Roxul comfort board
1×4 strapping at 12″ oc (also the airgap)
5/8″ hardie panels (2’x4′ staggered brick pattern)
I want to just screw the panels right to the strapping, and have open air gaps at the joints. (see example photo)
After speaking to my local Hardie rep, he said they don’t support that because water gets in behind the panels and they will swell, crack or freeze. He is adamant that all ends be flashed and there is no gaps by using easytrim or fry trim systems (to which it wouldn’t be an open rainscreen anymore and I have to focus on venting at tops and bottoms which will be more difficult with this reno)
I’m thinking its a crock of sauerkraut.
Does anyone have any long term experience with installing hardie panels in a rainscreen system?
