The NV was the first trussed span building manufactured by Rubb. The design originated in Norway and has a vertical sidewall, giving it the acronym NV.

The profile is characterised by roof trusses that start right at the top of the vertical portion of the leg truss and arch steeply over to the opposite side.

The high arch of the roof makes this profile ideal for bulk storage applications where the majority of the height is needed in the center of the structure.

It is also a structurally efficient shape for regions of high snowfall.
