All that adhesive? WTF are you talking about? Bubbles from what? Water vapor? All gasses dissipate at some point. The permeabitily of the material that constrains the gas is the variable. Helium balloons eventually fall to the ground due to dissipation.
Methinks you are ignoring the felt backing part of the equation.
All gasses are not equal in value. Some are more volatile than others.
Are you just screwing with me,or would you really like an explanation?
Food for thought:
Why is vinyl seam sealer stored in glass?
Better yet. Why is a sheet of vinyl used for a vapor retarder under a concrete GD as per some manufactures installation requirements??
