Vapor barrier in doors

Greetings, I recently put dynamat on my doors as well as on the inside and had to take off the vapor barriers. They did not come off very gently so they were destroyed. What are people doing to replace them? They seem important to keep the elements out...

Thanks!

 

Hope you did not cover up your weep holes?

 

For water to get out? Like in masonry? I covered up 1 hole but it's up high and above the speaker.
