So if there's Luan backing on a hung wall system, what's to keep the Luan from separating from the fiberglass should there be a leak? The fiberglass exterior is glued to the Luan, so the only adhesion is where the Luan meets the stud. I don't see it as delam proof. Still trying to figure out why hung walls are superior.

IMO they are not. If anything to me they are not as good. Fiberglass insulation will settle over time especially bouncing down the road. Lam walls also are much stronger for the weight. I am in industrial and commercial construction and we use Lam panels a lot on our projects (at customers request) and they are very strong and last very well compared to other processes. In the RV industry the biggest problem I see with their methods is that they use a backer (Luan)that is not resistant to water intrusion. The panels don't necessarily de-lam. The Luan gets wet and separates which causes the blister look. This can and will also happen with a hung wall using Luan as a backer. The problem with hung walls is that the Fiberglass insulation will also wick the water that gets in and make other problems.;)

Since Excel has closed its doors I believe the question was related to current manufacturers.

never received the courtesy of a reply to my e-mail requesting if StoneRidge has hung or laminated walls so I can't put them on the list.

still waiting for KZ to respond.

AS per Mbrower ,our newmar is constructed with luan backer glued to the studs 16 inches on center,easy to repair.

Unless the cutaway is wrong then it looks like the Stoneridge is laminated as it shows Luan backer.

The fiberglass skin will be laminated with a Luan backer but is still attached to the studs with adhesive. The fiberglass skin is very thin and would probably crack in time without the additional support.

With hung walls, the aluminum frame is 16 inch on center and provides the structural strength to the walls.

My 2008 KZ Montego Bay has hung walls. . . And I believe that the 2015 Stoneridge also has them...

Augusta RV does use hung halls. I own a Augusta Flex AF34RS and it does have hung walls. Luxe as well. You can call the factory 574-848-0200 they will be more than happy to answer any questions.

Why would they have a no delam warranty? As hung walls can't delam.

Got a email to the company; will see what they say.

Actually I hope they do use a hung wall as I need another company that may fit into my future plans.

This link is pretty clear on the type of wall used. Select a model for the wall info.....

Welded Construction
16" On Center Hung Aluminum Walls – 3.25 Thick

Got email back from company and they said they use hung walls I did ask for explanation as to why they would have a warranty on something that can't happen. Will wait for that reply! Maybe I missed something.

Ryan Miller(seems to be a straight shooter) from Augusta explained that the term "Delamination" is not used for the the sidewall coming apart but the sidewall coming off the studs. Reasonable explanation but not what most know as Delam.
