We are building a home with the cedar home style. However, because of
the higher cost of cedar and maintenance, we are considering using one
of the planks like Hardi Plank or Certainteed. These boards come with
wood grain texture and can be stained or painted to look like wood.
Certainteed even has a plank that comes stained with a 15 year
guarantee and looks almost like cedar. If anyone has experience with
any of these products, I would like to know your experience and degree
of satisfaction with them. We need to make a choice within about a
I have used Hardi Planks to replace Masonite siding on my house and to
exclusively cover my store room. IIRC the Hardi products have a 50 year
warrantee. It is a little difficult to work with but IMHO will never have
to be replaced.
Just a comment on the "15 year guarantee". The real cedar on my house is
going on 40 years old and while it doesn't look too pretty thanks to
previous owners putting on layer after layer of crap paint that I need
strip some day it's still perfectly sound.

I don't know certainteed, but Hardi seems great. It takes paint, but do
some research before staining. I think it will need to be an opaque stain.
I tried some oil stain and it was pretty blotchy. All things considered,
including the poor quality and cost of most wood siding, I'd go with a Hardi
This is an area in which I have some expertise. But I don't claim to know
First, Hardi and similar products are a fiber-cement material. If not
primed and painted ON BOTH SIDES, they will absorb moisture and cause
problems for any paint you use pretty quickly-even more quickly than wood.
Secondly, there are very few contractors that know how to put fiber-cement
materials on a house properly. Most just apply it like regular wooden
siding: WRONG! You should use the outside corners, inside corners, and
"J"-channels made for it. Thirdly, if a backer is not used (OSB, etc) this
material is pretty easy to break, and it is a PITA to replace. Cutting the
stuff requires a diamond saw blade if you're going to do any volume at all.
Personally, I hate it.
However, for the insurance wise, it has almost the same fire rating as
Were it me, I'd go with a premium vinyl siding. There are reputable
installers that can really make it look good.
I have used Hardi on a number of homes and never found that to be the case.
My own home uses Hardi. AAMOF, it holds paint better than any other siding
I've used. Hardi does NOT need to be painted on both sides as it is
That would depend upon your location.
Say no more ... there is NO requirement for J channels with Hardi siding.
You obviously do not know what you are talking about.
For the OP: Installation instruction are available at:
... and a FAQ at:
I install the hardi products constantly, and agree with Swingman that the
other responder doesn't kow what he's talking about. No J channel needed,
and the stuff is pre-primed, just install and paint. It's a dusty product
to cut and is somewhat of a PITA. Also, it's devastating to carbide blades,
so get a dimond blade or cement siding shears to cut it. For corners, facia
and other trim, I usually use a product called Mira-tec. It's basically
cement coated MDF with a smooth side and a rough cedar looking side with the
same dimentions as regular wood. It's considerably heavier than wood and
will split if it's nailed through the end grain, just like MDF. Also
devastating to carbide, and cuts dusty as can be. Both products should have
a long service life if installed correctly. hope this helps, --dave
Geez you went to school and apparently ate the teacher... I think you have
been sold a bill of goods. You do not need flashing and the caulk will last
much longer than you suggest. My caulk is going on 10 years and still looks
fine. Further, BRICK leaks more than Hardi. If you are getting leaks it is
your method of construction.
Seamless steel is even better than vinyl. No seams. For my house, vinyl
was $12,000 and seamless steel was about $13,400 or so. This was a new
house and the price included the eaves too.
The vinyl price seems high, but maybe they were going to do premium vinyl.
I am having my home completely resided with hardi-plank. Its an
extremely popular and accepted product in the Houston area, a tropical
climate. Wood siding of any type requires much more maintenance in
this area. Vinyl doesn't have that good a reputation here either.
I'll tell you what its like in 10 years. For now, it really, really
looks great. The material comes pre-primed and the builder is putting
on two coats of paint. They put Tyvek wrap underneath it. We thought
long and hard about adding sheathing beneath it. The builder said he
would be glad to do it but it was not necessary. I was concerned about
the "smoothness" of the application. He said that was determined by
the stud spacing and how square the studs were. My house had nice
tight stud spacing. He corrected or replaced some of the studs before
applying the siding. He completely rebuilt the garage door frame
(sagging) before adding the siding.
Both are excellent products. Keep in mind that if you use the stainable
stuff, you will have gaps between the edges where two boards come together
that will need to be caulked. I have noticed the stainable type really
shows these gaps where if you use the paintable stuff, you paint over the
caulking and it is not so apparent. Food for thought.
to add my 2 cents:
I just resided our house and renovation wih Hardi plank (replaced
vinyl)...I used stainless steel gun nails...It's important to drive any
nails you use flush with the surface, not down into the siding...
