Hi everyone -
Like many other newbies, I've gotten a wealth of information about different canopy options by reading through several of the discussions here on AFI, and by reading Larry's blog posts on the subject. Shows aren't too frequent in my corner of the country, and outdoor shows won't start until later in the year when the weather improves. Since I am not easily able to go see firsthand examples the discussions here have been very helpful to me in terms of researching a good solution for my needs.
My remaining question has to do with the different types of fabric I see used in the construction of the canopy tops & sidewalls. It seems like the Showoff/Trimline/Lightdome canopies use vinyl, making them waterproof. And for (most) popup style tents they use various weaves of polyester, which are not waterproof. But I've also seen the following fabrics listed and I was wondering if someone here could tell me more about them:
- Polyester with a PVC coating on the inside
- PVC fabric
The polyester w/PVC coating fabric is advertised as waterproof (not water resistant). I am wondering what it's advantages or disadvantages would be compared to vinyl? Is it durable, or does the coating tend to wear thin/wear off over time?
Is "PVC fabric" the same as vinyl? If I ask google some sites use the terms interchangeably but some make it sound as though there could be a difference.
Thanks in advance!

A true vinyl fabric will offer the best absolute 100% waterproof protection. Vinyl will usually be heat sealed or glued at all seams. The best tents, both domed and pop-up styles seem to use vinyl. All of the commercial rental tents of all sizes seem to be vinyl and i haven't seen a large commercial tent yet that was polyester.
The seams on many tents that are described as water resistant all seem to be sewn together at the seams and need a sealant treatment to protect the sewn seams.
i am not sure about many of the pvc coatings on polyester fabrics holding up as well as the true vinyl tops. I personally want the best waterproof top available for my tent and therefore i chose to go with vinyl. I have never heard of anyone complaining about leaky vinyl tops and I most certainly have heard many people complain about their polyester tops leaking and all their efforts to waterproof them.
My Trimline is vinyl and so is my Vitabri pop-up. Both, in my opinion are the best available for strength and waterproof protection
