1. Does the garage have a ceiling? if so what is it.
If sheet rock I would determine which way the joists are
running and drill 1 7/8" hole in ajoist cavity. I would use a probe to
find out if the the cavity is in fact empty. If so countinue to drill
7/8" holes every 5' in every cavity. Before blowing cellulose into the
cavities check to make sure the cavities are not open to living space,
if so block w/ fiberglass. Also make sure there are no heat producing
sources, such as a chimminy or "can" lighting.
You will want to fill these cavities on the highest presure setting
on the machine to achive a dense pack in the cavities.
2. Are the walls and the attick space of your bed room
insulated? If you are not sure drill a hole in a claset wall to
explore. Take a look up in the attic to see if you have insulation up
there
As far as recomended R values go. The DOE recomends an R-38 in open
attics and in walls and restricted spaces they recomend 3.5 pounds,
blown density per cubic foot

I want to have a layer of solidinsulationput up on the ceiling in the
garage.

Has anyone done this and if so did it help very much?
What RF factorinsulationwould you recommend?
