Home Improvement--General/Basement Insulation

Question
I've been insulating the ceiling in my unfinished basement with R30 fiberglass insulation (no paper backing).  I'm wondering if I should use this in the joists above my water heater and furnace?. Should I also insulate around the junction boxes that house my lights?  I plan on leaving the insulation exposed.

Thanks for the help!

Answer
Contact the manufacturer of the insulation to get its specification sheet to determine it flammability and its MSDS sheet for determining if it is to be left exposed or has other harmful respiratory hazards.

Junction boxes do not house lights. A housing is the correct term, and the housing has its own rating for contact of non-contact to insulation. That information is available from the housing manufacturer or on a label inside the housing.

Due to life safety concerns regarding some aspects of construction I may not be able to help with all questions.
I do not answer structural specification questions without a site visit.
