There are lots of insulating materials made for this job. fibreglass batts are the most common but you could also use blown in insulation which is made from ground up newsprint. or styrofoam sheets or spray on expanding insulation which is the best because it gets in all the cracks but it is also the most expensive. On some flat roofs the insulation goes on the outside and the roofing material goes over it but in most houses with a pitched roof the insulation goes over the ceiling and this leaves an air space between the insulation and the roof. Its very important to have proper ventilation in this area to carry away any moisture that may get there.

There are radiant barriers, such as foam or bubble wrap covered with aluminum foil. Rock or mineral wool, which come as batts or loose fill. Fiberglass as batt, roll and loose fill. Styrofoam sheets, urethane foam sheets and spray-in. Vermiculite, and cellulose loose fill.
