Where to finish breather membrane in door opening

[jamesmonk83]

Hi All,

 

I have a (probably stupid) question, I've wrapped my SIPS garden office with a breahable membrane. The front is essentially a single large opening where a sliding door wil be installed in the new year. My question is where should the breahable membrane finish here? At the moment I have the membrane coming into the recess where the door will be installed (so it's just inside the room). I'm wondering whether I just wait until the door is installed and then cut back anything that is showing on the inside or whether there's a "proper" way of finishing it. I'm just worried about the membrane providing a route for water/moisture getting into the room but I also want to provide maximum protection to the external walls as well.

 

The attached pic (taken on an angle!) shows a side on view of the opening with a crude green line drawn showing the rough position of the installed door.

 

Thanks,

James

Exactly my problem. In my case for all the widow openings as well as the door. I found this interesting video online which gives a different viewpoint to others I've seen https://youtube.com/channel/UCRKjjDhP3w2lnx3csu3G3aw or look for DIYfferent on YouTube. I'd be interested in other views on this.
