Breather Membrane for timber frame - What side faces out?

[dunny1234]

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

Why don't you ask the manufacturer?

Normally writing side out isn't it, these manufacturers never miss an op for some free advertising.

Smooth stops the water coming in, waffle lets it go through
