Insulation-best materials, thickness
Heat flows naturally from a warmer to a cooler space. In the winter, this heat flow moves directly from all heated living spaces to adjacent unheated attics, garages, and basements, or to the outdoors; or indirectly through interior ceilings, walls, and floors--wherever there is a difference in temperature. During summer, heat flows from outdoors to the house interior. To maintain comfort, the heat lost in winter must be replaced by your heating system and the heat gained in summer must be removed by your air conditioner. 
 Project description:
Insulating ceilings, walls, and floors decreases this heat flow by providing an effective resistance to the flow of heat. currently fiberglass the most commonly used heat insulator for inside the walls and ceilings. Other widely used insulating materials are cellulose, rigid polyurethane foam, Styrofoam and etc.

In this project you will compare some of these materials to see which one is the best insulating material. We also want to see what is the effect of thickness of these material on their insulation properties.
