Rigid panel boards are made of extruded polystyrene (XPS) or at times they are made of polyisocyanurate foam. Note that these panels are attached onto the wall exterior and act as a vapor barrier. During cold weather times, keep the boards inside the walls to prevent warm air from escaping.

Tip # 5-Roll or batt insulation

Roll or batt insulation works best on attic. It is made of cotton, fiberglass or wool. Fiberglass is common material which is readily available at stores, so it is wise to choose this option. Simply lay roll or batt right between the joists of the ceiling and you are good to go.
