What type of Rigid Insulation to use?

[Garyl53]

Hi, I have about 60 ft. of concrete basement wall that is uninsulated in an area that I would like to put my workshop and some storage. This area is located below a heated main floor and next to a finished heated basement. There is no insulation on the ceiling, concrete walls and framed walls of this area. Is there a type of rigid foam insulation I can glue/fasten to the concrete that comes with some sort of finish on the interior side? I would like to not have to put up wallboard since it is just a workshop area. Any suggestions or recommendations appreciated.
Thanks,
Gary

all I can think of is dow blue board or corning pink board
there are other types of isoboards..but I think that any
foam board would have to be covered with sheetrock for
a fire protection.

(not much good with basement questions..but will get
the ball rolling!)

best of luck.

Fire codes do not allow for exposed insulating board like XPS or EPS. You can use foil faced isocyanurate.

The most common way to insulate a basement is by building a framed wall, filling it with fiberglass batts, and covering it with drywall. This unfortunately creates a cavity that is difficult to air seal and difficult to dry if the basement wall ever gets wet. Polystyrene insulation, equipped with imbedded wood fastening strips, is a better choice because moist air can't circulate behind the insulation as it can with the stud wall, and it will dry quickly if water enters through the foundation wall.
