Costruzione Cap e Sandwich
Manca nel mio bagaglio nevo-culturale una motivazione per le diverse costruzione.

Sidewall Construction
Sidewall construction comes in two major flavors: cap construction and sandwich construction. Cap construction is a type of sidewall construction where the topsheet is rounded to meet the metal edges, and it has a few advantages:
It's cheaper to build.
It makes it easier to create a board that is more torsionally stiff.
It can provide more edge hold, because the edge profile is thinner than sandwich construction.
Cap boards tend to be more lively.
and disadvantages:
They have durability problems: they will start to lose their structural integrity if they get dinged from the side.
They are difficult if not impossible to repair.
Cap construction is also somewhat weaker than sandwich construction.
Despite having good edge hold, cap boards tend to transmit the all the terrain bumps to the rider.
Sandwich construction is a type of sidewall construction that looks like a sandwich from the side. It is stronger than cap construction, more durable, and easy to repair. Nominally, boards with sandwich construction have less torsional stiffness, but snowboard makers who know what they are doing can build a board with sandwich construction and still maintain good torsional stiffness. Slantwall construction is a type of sandwich construction, and may help provide more edge hold with a thinner edge profile.
Dualtec: Some boards have cap construction at the tip and tail, and sandwich construction in the middle - Rossignol used the term "Dualtec" for this combination.

some corrections:
cap: easier to build yes, and cheaper
stronger torsion resistance: not really.. it was the case with the first salomon monocap skis.. but now no one uses that tech in races..
edge hold: not true otherwise all world cup ski riders would be on cap!
lively: nothing to do with cap > it has to do with camber, core and fibers used.
