Johns-Manville insulation - asbestos?
 
I have discovered that the insulation behind my bathroom wall is made by Johns-Manville. The house was built in 1968 and I was concerned that this stuff might contain asbestos. Is it possible?

It's possible:
Sometimes, the only way to find out for sure, is to contact a state certified inspector and have insulation samples analyzed by a state certified testing laboratory.

Is it ok to just leave the insulation intact and drywall over it even if it does contain asbestos?

Yes, If you do not disturb it, it will be fine.

To learn more about asbestos:

Also, it's use in various early construction materials:
