Increasing Insulation Effectiveness
Types of Insulation / Where to Add Insulation
 Houses loose and gain energy is through the movement of heat through solid objects such as walls, floors , and ceilings. Heat always moves toward colder air in an attempt to equalize the temperature. Insulation is helpful because it traps tiny pockets of air which retard the transfer of heat. Insulation won't stop heat entirely, but it will slow it down.
Insulation's effectiveness is tested by its R- value, its ability to resist the heat flow from warmer to cooler areas. The higher the R- value, the more effective the insulation. It is important to remember that a material's insulating ability is based on R- value, not thickness.
