Although heat rises, when a space such as the attic gets to be full of hot air the heat will naturally radiate in all directions, especially when the air is hotter in the attic than in the house. Remember that heat will flow to the cold. What the fiberglass insulation does is creates a thermal barrier between the attic space and the living spaces below. Plaster board doesn't do this effectively but does stop air movement.

I have had a number of clients with older homes who have asked me how much insulation should I put in. Your local building control authority will have a minimum set by the government (most building supply stores will know these codes), but my recommendation is to put in the minimum and then what ever extra you can afford after that. I have double insulated my home and although it is a small extra cost it is well worth the effort. Some say it is not necessary, or it is an overkill, or that there is only so much insulation required before it is a waste however the proof is in the reduction in power or electricity bills so it works well here.
When installing the blanket use safety gear such as a dust mask and gloves, be careful not to stand on the ceiling itself as it won't support you, use the framing instead. Don't cover the light fittings with the blanket, use an approved light fitting cover to avoid any risk of fire.
