How to make Sheet rock layer remain airtight over time?

Joe Macker
4 years ago

When sheet rock is installed and taped on the seams and compound is applied, I guess the room is airtight from the wall cavity. But does it stay this way? Over several years I have seen cracks appear in the drywall which I guess is due to settling. Does this mean the inhabitants are exposed to what is in the wall cavity. E.g. the insulation in the cavity and potentially any chemicals that were put in the wall cavity during construction could then affect the inhabitants. Is this correct? What can be done to prevent it?
