SERIES 2100: Field Sound Transmission Class: (FSTC) 21.

Not a very good STC for studio purposes snapper. Our sliding glass doors are rated at 33 STC each.

not those john, if you scroll down a little more there
is an stc33 rated door. I was curious about what kind of
effect the accordion shape would have on the room.

Ah this one?

SERIES 3300: Field Sound Transmission Class (FSTC): 33

Cool 33stc is pretty good, so what do you want to do with them??

cheers

I was thinking of a pair for the control room door. But what
about the shape?

 

[John Sayers]

Well - you can't see through them so what's the advantage?
These are 33 STC and you can see through them:

BTW we paid around $800 each for them - how does that compare??

cheers
