The attic is one of the largest sources of potential heat loss in a home and often one of the most neglected areas when it comes to insulation—especially in older homes. It’s why adequate insulation is so important?and without it, your energy bills could be significantly higher. Whether your attic will remain unfinished, be used for storage or be finished for use as living space, make sure it is properly insulated with the right amount and kind of insulation.
If your attic is unfinished and you’re insulating it for the first time, you will install insulation in the floor joists. If you’re building a new home, install ceiling insulation from underneath before you put in drywall. You should use faced insulation when a vapor retarder is needed. However, only unfaced insulation should be used near chimneys and flues.
