Do you really need to insulate basement walls?

Why is my finished basement so cold?
Cause #1: Below-grade walls and floor Simply the fact that basements are located underground makes them inherently colder. Dirt is a very good insulator. As a result, the basement will stay cold even during the summer months.
How do you insulate an already finished wall?
With a small hole ranging from ½”-2”, certain types of insulation can be injected directly into a wall cavity. The three main materials used to insulate existing walls are cellulose, open cell spray foam and close cell spray foam.
What is the cheapest way to insulate basement walls?
The smart and inexpensive way to insulate joist bays is to use extruded polystyrene (XPS) foam insulation panels cut to size to fit inside the bay and “glued” in with expanding foam. When the expanding foam hardens, trim away the excess and cover the foam with a piece 1/2″ thick drywall to meet fire code.
Should you put a vapor barrier on basement walls?
While a vapor barrier won’t stop moisture from making its way between the foundation walls and the actual barrier, it will help prevent water from coming into the basement. This, of course, helps to dissipate moisture and mold – two things that no one wants to see in a basement.
Should you insulate between basement and first floor?
Any frame walls in the basement (as with a “walk-out” basement above ground level) should be insulated with fiberglass batts installed between the studs. The insulation should extend all the way down to the basement floor, or at least to below the “frost line” (the depth to which the ground freezes in winter).
Can you spray foam a basement?
In most cases, spray foam insulation will be used in the basement walls unless the drywall has already been put up. If spray foam is used, then there’s the decision between closed and open cell spray foams. This can also factor into the cost because closed cell tends to be more expensive than open cell spray foam.
Should I use spray foam insulation in my basement?
The best way to insulate the interior side of a basement wall is with foam insulation that is adhered to or sprayed directly on the concrete. Any of the following insulation materials are acceptable for this purpose: closed-cell spray polyurethane foam or either XPS, EPS, or polyisocyanurate rigid foam.
When finishing a basement do you insulate the ceiling?

How do you insulate a basement wall that is already framed?
Use spray foam insulation on basement walls when the walls studs have already been installed. Spray foam is best when you need continuous insulation with no gaps to permit air infiltration. It is an excellent solution for irregular walls and for walls with many cracks, seams, and joints.
Should you insulate concrete basement walls?
Walls. Basement walls should be insulated with non-water sensitive insulation that prevents interior air from contacting cold basement surfaces—the concrete structural elements and the rim joist framing. The best insulations to use are foam based and should allow the foundation wall assembly to dry inwards.
How can I make my cold basement warmer?
