Hung Walls ?

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?

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.;)

My take on the subject is that repairs if needed make it a superior construction method over non-repairable laminated walls.
The other thing that I wanted to see as the original poster is I wanted to see if mostly the better constructed and better built 5'ers used this method - aka DRV, Excel, Lifestyle even New Horizon.

I had to fix my closet where the previous owner missed a leak and yes the luan board will delaminate. However, I was able to replace the damaged wood fairly easy and repair all the water damage to as new condition. I was able to disassemble the wall and rebuild it with new materials. I think this is one of the advantages of a hung wall type construction. Both wall construction techniques are very good and will last the life of the coach provided maintenance is kept up with minimal leaks. I believe that most all rvs will leak at times and some damage will occur that will require repair and I believe hung walls will be easier to repair.

I think Excel was as well.

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

I thought about that but since they just closed the doors there is probably unsold current models.

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.
