My wife wants an arched entrance to the front of the house -- and of course
I just say OK.

The arch will cover a span of about 72" and will be about 18" in height.
Okay no problem.

My question is -- Since this is an outside project and subjectto heart and
humidity extremes I am wondering about material to use. I thought about
glueing up cedar but that doesn't hold well -- at least from my experience.
Then thought maybe some glued up white oak might do the trick but I would
need to go find some -- the guy I normallly buy from is about 400miles from
here so not close enough for a weekend project.
Any thoughts about using exterior grade ply? I always dread using ply where
it is exposed to the weather.
If I cover the ply with a urethane will this help prevent decay?

Any ideas. Dummy simply says ok and now I need to figure it out. duh.

Thanks. Thom

So, is this going to be a hole cut in the side of the house and with a
door? Same thing at the end of a porch? Maybe at the front of a
porch with no door?

Not to mention how it looks. You aren't covering with siding or
stucco?

No. Using pressure treated plywood would. So would using non-PT and
a liberal application of Cuprinol.

Any ideas.

Around here, most houses are block. Arches are formed with 2 pieces
of exterior ply cut with a curve. One inside, other outside. Short
pieces of 2x4 are nailed between the two to form the bottom of the
arch and firm up the ply. Windows/door frames are fastened to the
pieces of 2x4. Ply and any 2x4 part that shows are stuccoed over.

Good questions -- not enought info to work with it sounds like.
The porch is about 6 foot wide and 4 foot deep so that it creates a little
place to stand out of the rain beofre going in the door.
The arch istself would hang from the front part of the porch -- the entrance
would havet the arch at a 7 foot height then go 4 foot and then finally in
the door.
Mifey poo has a greenish color trim she want to use. The new arch would be
painted this greenish color to match the rest of the trim. So no siding or
stucko or bricking. Just paint.
The arch will be about 3 inches in depth total to give it a little
perspective when looking at it from relatively close. From the street no one
can tell how thick this is. I anticipate using layers with a spacing
(1.5inch) to create a sandwich effect.

Hope this helps with the needed info.

Thnask again.

Is it under a roof covering? Direct rain/snow/etc.?

I like the sound of the white oak, but, being from California, am not
certain why a good Western Red Cedar would have a problem.

Where are you?

It's under a roof covering but still the rain and snow can get to it.
I'm from near St. Louis so we see all 4 seasons.
I've never had good luck when joining cedar...I thought about it since it
has inherient properties for the weather and is also light in weight
compared to oak.

Yep.

Occasionally, in this very group, people have mentioned a sheet goods
material that is used to make outdoor signs. IIRC, is has a smooth,
bonded material (phenolic?) on the to be painted side. I'd seriously
consider using it, don't recall the name. If you don't mind the
rustic surface, T-111 could be used too.

You're on the ball! I think you're talking about MDO or HDO - and
although I've used the stuff, it didn't even occur to me that it would
be about perfect for this application. With the edges sealed it should
last a _very_ long time.
