If you *HAVE* to use fiberglass, then frame it in and cover it with foam board. The local Lowes here carries "R Max" R-Matte Plus 3" with foil backing in one side. This will give you a couple of advantages... first it will encapsulate the fiberglass so you won't have the loose glass fibers floating around for you to breathe, as well as the foil facing will reflect the heat and light back into the room. My grow room is nothing more that a box framed with 2x2 furring strips, and foam board. Its very effective, and inexpensive.

BTW... you can use aluminium tape to seal the seams and any holes in the foil facing
