ATTIC INSULATION

Loose-fill cellulose or batt insulation is typically installed in an attic. Loose-fill cellulose insulation is usually less expensive to install than batt insulation, and provides better coverage when installed properly. See more on different types of insulation. Before insulating, seal any air leaks and make roof and other necessary repairs. If it is located in a conditioned part of the house, also remember to insulate and air seal your attic access.

Insulate and air seal any knee walls — vertical walls with attic space directly behind them — in your home as well. In addition, if you’re building a new home in New Jersey or remodeling, make sure any attic decking that provides additional storage space or a platform for a heating and/or cooling unit or hot water tank is raised above the ceiling joists to leave room for adequate insulation. Finally, if you live in a hot or warm climate, consider installing a radiant barrier in your attic to reduce summer heat gain.
