Basement Insulation Tips
Being below grade, your basement is probably the most efficient to heat and cool room of your house. The earth makes a great insulator, and you really don't need to insulate the walls of your basement if it was not for the problem of moisture. It is best to keep the walls of your basement at least 1 to 2 inches away from the foundation. Insulation will wick up any moisture or condensation that may occur on or near the foundation. It is best to use properly installed R11 or R13 PAPER FACED insulation, making sure it fits snugly, but not too tightly between the stud pockets, Making sure that the back of the insulation does not touch the foundation. This is code in most towns in the Chicagoland area. The air gap between the walls and the foundation allows for some circulation of air, and keeps the insulation and the drywall free from mold and mildew. If the wall needs to be built closer to the foundation, i.e. if there is a tight fit around a staircase, use rigid foam insulation cut fairly precicely to fit into the stud pocket. Some types of the rigid panels can be places directly up against the foundation, as they do not provide a medium that would grow mold.
The vapor barior that the paper backing is the only real important part of the insulation system in a basement. It allows the walls to breath moisture back and forth through the insulation and drywall, where plastic would not. Plastic should never be used in the walls because it traps water in the walls and facilitates mold growth.
