English to Spanish Tech/Engineering Construction / Civil Engineering

Here you have more context:
"Casing: Choose the type of casing you want to use. You will have to decide whether to place wall casing materials (like cinder blocks and bricks) between the beams, use prefabricated panels, place curtain walls, or install glass (for a steel structure)".

I have translated "casing" as "revestimientos", but I'm not sure about the meaning of "wall casing materials".

Any suggestion?
