This Flash object begins with a screen that reads, "What's up there in the attic—and what's not up there—can make a big difference in the monthly cost of owning your home. Is there enough insulation? What condition is it in? What about ventilation and air sealing? It pays to get better acquainted with the least frequently used space in the house." The screen then changes to the image of the attic of a house, showing the wooden rafters as well as the insulation along the floor and the open door from the floor below. There are certain elements labeled as clickable links, which are also found in the left navigation of the page: Attic Stairs, Ventilation, Fan Vent, Insulation, and Can Lights.

Check out the toolbox below for guides to insulating, air sealing, and lighting your home.
