DRAM 2006 tech
 
Hi,

DRAM means "Dyneema Reinforced Airex Model".
When DUR-X is used with DRAM both Inner and Outer PVC (Airex) core are used.
What happens with the rest of boards (No DUR-X like Isonic DRAM)? There is a PVC core inside?

I couldn't find this information in the TECH page DRAM Figure.

Thanks in advanced, best regards !!

That's not PVC "core". The core is EPS. PVC is the foam used for the shell, sandwiched between the (carbon/dyneema/glass)fiber-epoxy or wood skins: 2 layers ("double sandwich") for Dur-X, just 1 for other boards.

Sorry!! I used "core" term were "foam" should be used ...
So, DRAM without DUR-X is single sandwich.
Few year ago, before DUR-X tech arrived, DRAM tech was double sandwich:

Isn't it ??

Ooops. I had a look at Starboard "technology" page and I discovered that: 1) "The Dur-X construction label signifies the use of heel bumpers, oversized, angled reinforcements and optimized external reinforcement patches. The Dur-X standard is used for Acid and Evo models, both Wood and TechnoraTM. The Evo 80, 90 and Acid 80, 86 Technora use a single sandwich construction, other sizes use double sandwich." and 2) they call "core" the sandwiched foam (it seems more correct to me to call "core" the core).
