Identifying Hardie Board?


#1

Just reading about the various challenges to washing Hardie Board. I can’t tell from pictures how to differentiate it from vinyl siding. Any tips?


#2

Hardie is made out of concrete. Vinyl is made out of vinyl


#3

On Hardi the outer/interior corner boards are 1 inch (typically). Here in GA they are painted white, like trim. Vinyl will have casing the same color, again, typically. If you look at the bottom of each lap, Hardi is very thin roughly 3/8. Vinyl overlap is thicker.

Sheesh, Go to a building supply store and look around. Ask questions there. You shouldn’t be washing anything if you don’t know the difference.


#5

Yep. If you tap Hardiboard you can tell what it is. It’s truly thin cement board.


#6

When your looking at it and your like that’s not vinyl, that’s wood siding, then your like naw that vinyl…then your like naw that’s wood.

That’s hardi / LP smart siding is what new construction calls it now.


#7

Just saw they make a smooth LP siding now too.

Edit: maybe they always have, but just saw it recently


#8

Hardi siding has cement and wood fibers in it. LP Smart siding has wax, expoxy, and wood fibers in it. Smart siding is similar to OSB I believe.


#9

If you’re unsure push on the siding, Hardiplank will be firm and vinyl will flex. If your just looking at pictures on the internet your going to have a hard time telling the difference. Very easy to tell the difference when looking at it in person.

Thanks guys, wasn’t aware it was made of a different material. I thought it was a different kind of vinyl siding. I have never seen it around here, and I would definitely be able to tell if it was concrete or vinyl. I’m guessing it just isn’t very common where I’m at.

Or I could just ask questions here. Way faster than going to the store.

But you would learn more going to store and actually studying the product and talking with rep about the pros and cons of the different products, thereby being able to speak knowledgeably to your clients. But that would entail an hour of your time to become more professional.
