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.
What happens if you don’t insulate basement walls?
When a basement is finished but not properly insulated, warm air from inside the finished space can come into contact with the foundation walls, behind the insulation. Condensation in your finished basement can build up in insulation and the wood framing, and even pool on the floor behind finished walls.
Will insulating my basement keep my house warmer?
In cold weather, the temperature in a basement or crawlspace can be twenty to thirty degrees colder than that in the living space. Insulating the basement or crawlspace will reduce this heat loss, saving space heating energy and improving comfort by keeping the floors warmer.

Use furring strips attached to basement walls: basement panels can be used in a basement finish not using studs and drywall. As such, all you need for support are some furring strips attached to basement concrete side walls.
How do you insulate basement walls in cold climates?

How do you insulate existing concrete block walls?

This is why it is important that interior insulation assemblies be constructed as airtight as possible.

Should I use visqueen or plastic sheeting on the framed basement walls? No you should not, as plastic will prevent moisture from moving through the wall and will lead to mold and damage.
What R value is needed for basement walls?
