Anyone ever constructed/owned a canvas awniing? Late last night,
over wine, a (non-sewing) friend and I were debating the merits of a
canvas awning. The claim is that an awning, properly installed, and
permanently attatched to the house, would be good for 20+ years. Let's
assume the person seeking to erect this awning cannot afford one oof
those wonderful retractable awnings, so something relatively simple is
on the table, but of a high-quality, outdoor canvas
I seriously doubt that kind of longevity, as this particular
hypothetical awning would be receiving sun almost every day, all day
long; thus, in my opinion, fostering dry-rot much earlier than if the
canvas was erected in, say, a shady, or somewhat sheltered-from-the-sun
spot. The climate here is usually hot and sunny, with, frequent years
of 10 to 11 months growing season for gardening. So, lots of sun, even
in winter.
IIMHO, I'd opt for a sunroom with a passive solar-collection type of
flooring, but it's not my call. (You can lead a horse to groats, but
you can't make it eat.)

Check out www.sunbrella.com
Any Awning worth owning will be made from SUnbrella fabric.
They warranty it for 5 years so Seems like 20 might be a stretch in your
climate

Yeah, I was going to say I think 5 years would be about the max. Southern
Indiana was a much more mild climate. Starting about October, we got a
whole lot less sun that you would out there, Cea. And that continued (gray
days mostly) till about March or so. Our neighbors had one of those garden
swings with an awning over the top. Sat outside all the time because where
ya gonna store one of those big things???? It lasted about 3 years, then
she had me come look at it to see if it could be repaired. Between sun,
rain, snow, etc. it had started coming apart at the seams. Well...the seams
were all still there but the fabric was rotting away on either side of the
seams. I don't know that it was Sunbrella, which is great stuff. I do know
that they got it someplace like Home Depot or something like that. So it
had to be fairly decent fabric. But I think 20 years would be stretching
even Sunbrella.

Oh! I know where you could find an answer. http://www.beaconfabric.com/
These folks are really great. They used to do a lot of custom sewing, boat
covers, awnings, etc. I think they have stopped that. Buddy and Lydia are
both on a different sewing list I subscribe to. They are really helpful and
generous with their knowledge. So if you can't find an answer to your
question on the site, zip them an email. I Know they would be able to tell
you for sure if it would last that long. :)

I second Ron's response. Sunbrella is used (exclusively?) in the Galveston
area on the Texas coast. Lots of sun, believe me.

I am in Florida for half the year and a few people have one of those
carports with a canvas top for their boats. They need to replace the canvas
about every 3 years and the bungy cords that hold it on. HTH Barbara in
