Should you insulate attic rafters?

As Joe mentioned, that will cut off airflow in the attic and cause ice dams in the winter. Ideally you want a “cold” attic – lots of insulation between the ceiling and the attic, and no insulation between the attic and the roof, along with plenty of soffit and ridge vents to keep the air circulating up there.Click to see full answer. Likewise, people ask, should you insulate attic roof rafters?Insulating between rafters will do no good, because the attic should be ventilated, and the rafter insulation would be between two unheated spaces. You can add insulation to the floor; the more the merrier. Just don’t put it in the eaves. Also, make sure the attic is well ventilated.Additionally, do I need insulation in my attic? Attic Insulation Loose-fill or batt insulation is typically installed in an attic. 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. Just so, should you insulate between rafters? Yes. If you’re laying insulation between the joists, the roof space will become extremely cold in winter. However, if you insulate between the rafters rather than the joists of your attic, the space will be warm and your pipes should be fine.Can you over insulate an attic?But there may be a theoretical point of “too much.” If a home is over-insulated and is too tightly sealed, moisture can get trapped inside. Without proper ventilation, a home can build up too much moisture, especially in the attic (warm air rises), which can cause mold problems and, overall, lower indoor air quality.
