I have only heard good things about James Hardie concrete fiber siding. It's hard to install, but virtually indestructible and will last a lifetime. It never faces and is extremely weather resistant. I got some installed from conservation construction of texas and it's looked the same since the day i installed it 5 years ago.

timmy55,
I like Hardie I have the prefinished lap siding on my own home, but just last week I saw CELECT PVC siding and was impressed , it is light weight , easy to cut ,prefinished and has end interlock laps to keep out water , if I did mine again I would use the PVC

I have now watched many Youtube videos on sheathing /exterior siding /Hardie - Cement Board use/Wraps & liquid wraps. I'd like your opinion on reasonable solution for a new project.

I'd like to enclose the two right side bays of this house to provide a storage area. The space will not be conditioned and the street and gulf side walls need to be installed as 'blow-out' walls.

We want to enclose the area using cement board on the exterior to have a durable product. The question is what kind of underlayment to use that will protect against water incursion/etc. without being overkill.

Having read and watched Austin Builder, Matt Risinger's blog and video on "Delta Vent SA Review – Peel & Stick Housewrap" I thought that might be a way to go so I asked a local builder about this layup:
1. 2x4" 16 inch OC framing of wall panels
2. 1/2" plywood sheathing (is pressure treated more expensive?)
3. weather resistant barrier [Peel & Stick housewrap]
(recommend Delta Vent SA made by Cosella-Dorken or TYVEK RainGuard)
4. 3/4" rigid foam board with radiant barrier foil
5. rain screen (for air gap}
6. Hardie plank (siding)

His reaction was not positive, he hasn't seen that before. I explained I was trying to prevent water incursion/rot such as has occurred on almost all the stucco siding on the house. He suggested using DUROCK and Tyvek.

It makes me wonder if I'm being nutso overkill for this space.

Having seen Risinger's recent TEMCO videos - perhaps an option could be :
1. sheathing
2. Temco ExoAir 230 liquid barrier
3. some Rain Screen product
4. Hardie Plank

THis is a southern coastal build with heat and humidity, add harsh coastal condition and you've got this project. I'd appreciate any comment and suggestion you might make for a durable but not overkill design.

Thanks;

cmkavala -

IS that CELECT PVC siding subject to warping? I suspect like PVC deck planking that it fades.
