ZNLine factory: Enigma Building
Rajul,
My guess is they are using Nomex for it's thickness. Just like a spar, the farther apart the inner and outer skins are, the stronger the fuselage will be. That's why thick airfoils tend to be stronger than thin airfoils, even if they use the same spar system.
On the fuselage, the Nomex separates the inner and outer skin, making it stronger than if the 2 skins were attached together.
