I know i sound stupid, and maybe i am?????

I had a load of housewrap delivered, but there's no logos on it and both sides appear shiney. What side should face out?

Side A. is like the top of a waffle with miniture pits

Side B. is flat

I'm still not sure what side faces out?

Sorry to be a pain, but any help means sleep for me tonight, thanks

PLease help!

Flat side out.
 
The outside face as it is rolled is what goes against the structure, makes it easy to roll it out along the wall or a flat roof.

I've usually found the waffle side is out.

I've got a roll or 2 of Tyvek at home and will have a look. I'd assumed that the waffle side would be the underside as the smooth side would be easier for the printing and Tyvek is printed on 1 side.

However - Jase is correct, in that as you unroll the fabric, the face of the fabric that becomes visible is the outside face. Only exception I can see is, if there was a cockup at the factory and the rolls were wound incorrectly and then offloaded cheaply as seconds.
