Getting Started With Attic Insulation DIY Tips

Fiber glass insulation is an easy do-it-yourself project that can pay big dividends in the form of lower energy bills. But first, be sure to air seal your attic and to address duct leaks. The EPA recommends sealing all air leaks before installing new insulation. Adding a layer of fiberglass to your attic can help trap warm air in the winter and cool air in the summer, prolongs roof shingle life, reduces your energy bill and may even improve your indoor air quality.

To know if you need more insulation, check out our article on Getting Started with Attic Insulation DIY Tips. You will need to determine your current level of insulation and subtract that from the recommended amount based on R-value. Then you can purchase the appropriate blown-in insulation at a home improvement store or hardware store. Be sure to choose unfaced insulation that does not contain a vapor retarder (unless you are adding a second layer over existing rolled-out fiberglass or another type of faced insulation).

To blow the new insulation into your attic, remove a plank board and slide the hose of your blown-in machine into the attic. Begin at one corner of the attic and work your way across the ceiling. The hose will naturally push back as you blow the insulation into the bay, telling you when it is time to move to the next section. Continue working in this fashion until you have blown insulation into three rafter bays. Be careful not to cover soffit vents and avoid covering any recessed “can” lights that are rated IC (insulated ceiling). Be sure to weatherstrip the attic hatch or door and install a gasket around the opening.
