What do you know about the "Azdel Composet Sidewalls"?

Luan plywood is at least 3 cross plies thick and glued. This is why plywood is strong for its thickness, but it will degrade when exposed to water.

Worse, luan, like almost any wood, will swell with long term exposure to water. If the outer/inner skin is glued to luan, that bond will fail with swelling.

Lake everything new, it will take time to really tell the tail.

It's the UV rays that kill the outside plastic. Keep that under cover and it should last forever.

Well, it is covered with Fiberglass, and Gelcoat. so the actual AZDEL will not be in the sun. The gelcoat will last as long as any Gelcoat will, ant that is a long time if you keep it clean and waxed.

Does that mean it's good?

I think it is better than luan but for the added money I would rather have the hung wall construction because it can't delaminate like the bonded side walls either the luan or Azdel.

It is a thermoplastic material that replaces the luan as wildman said. It won't absorb water like wood products and swell so that is an advantage. The strength of the sidewalls is more a function of the wall thickness rather than the core material.

Thanks for the posts, Everything I've read had nothing but good things to say about it! It's also a much more expensive product than the typicle sidewall for a motorhome! That says something in itself, what coach builder would put more money into something that wasn't better?

I also found this product has been around for a long time, so it isn't like it's new and untested! I first wanted to know If I should stay away from coaches that have it? I have found it's good to persue coaches that have it!

Have it on my 2011 Lance Truck camper and so far very good.
