Insulating foam is just one thing that can be used. Insulating the wall cavity stops heat exchange with the exterior which is a problem during extreme climate conditions like winter and summer. Insulation works by stopping air movement through the cavity. The real trick of insulation is that it isn't the insulation material itself that stops the heat exchange, it is the air trapped in it that does. Air is a poor conducter of heat energy provided that the air is stagnant (not moving around). When applied, the foam bubbles up as it expands, trapping air in the bubbles as it hardens making it an excellent heat insulator by virtue of the air trapped in it.
Foam or fibre insulation.

Insulation is relatively cheap, certainly when compared to the possible gain in terms of heating costs. Rolled insulation or "batts" of insulation can be put up very easily if your walls are open. If your walls are closed foam is still a possibility.
Foam is a good insulator- this means that it traps still air and prevents heat travelling and being lost. Heat is lost more easily through the air in air-filled cavity walls as the air is not kept still.
Polyurethane foam insulation is the most popular insulation on the market today. It is easily installed, it is sprayed into the walls where it coats and hardens. All home improvement stores carry it.
Usually with some form of insulation in the walls such as spray foam. Insulation keeps the heat in the house, used in attics and basements especially
A contractor build two houses with 2 by 6 walls. He sprayed 1.5 inches of foam into the walls of one house and used standard fiberglass insulation for the other house. The house with polyurethane insulation always had lower electric bills. They believe this is do to the fact that the foam is the worlds best insulation and it seals all air leaks.
When you replace wall insulation, you are first going to have to tear down the entire walls. You will have to place a layer of foam and fiber to keep the wall warm.
it's stronger
Closed-cell foam insulation differs from open cell foam insulation in the fact that closed-cell foam insulation has tiny foams cells that are closed and packed together. They are filled with gas that helps the foam rise. Open cell foam does not have this characteristic.
Yes, foam rubber sheets can be used for insulation. Practically any object or item that has foam on it can be used for insulation purposes.
