Hey, Thank you Poli. You're right on what you say, and agree with you. But I checked Oxford Superlex and I got two good options,
Sheetrock® n (AmE) placa de yeso, pladur® m (Esp)
Thank you once more for your inspiration!
As far as "plancha/lámina de roca" goes... well, yes, I guess we would be entering into the Españanglés, variante autóctona del Spanglish.
