GLASSWOOL INSUALTION ON CHILLED AND HOT WATER PIPES
GLASSWOOL INSUALTION ON CHILLED AND HOT WATER PIPES
(OP)
The specs call for 1 inch thick glass wool insulation with aluminum foil vapor barrier for chilled and hot water networks inside the building and 2 inches insulation with aluminum cladding for external above ground piping. For better adherence to pipes, would there be any issues if the insulation is applied with adhesive instead of just using aluminum tape to close the openings?

If the tape fails, your vapor barrier is compromised, and you'r have to replace the tape anyway. How is adhesive going to simplify your situation?

If you ever have to service a pipe with glued on glass wool insulation, you will instantly see why it is a bad idea.
Use the tape and forget the glue.

You need to recalcute thickness, of course.
The only reason to use glass woll indoor is fire spec that calls for inflammable material, flamability class should be part of spec.
If that is the case, than forget aluminium foil and use alu-cladding indoors as well.
Wool+tape is worst combination in terms of quality. My personal opinion, of course.
