I have an older house and I am looking to improve the insulation around it. The garage ceiling has sheetrock, but from the workroom I can see that they used a double faced yellowish colored insulation.
The insulation has settled to where it is sitting on the sheetrock leaving around 3 inches of space between it and the floor above. I was thinking about blowing some cellulose into that excess space. However, I am not sure if it is better to tear down the sheetrock and reinstall the installation (rather not of course). If I do reinstall, which way should I face it.
* I am located outside NYC
* We very rarely turn on the A/C in the room above (the attic fan does most of the cooling)
* The room above (master bedroom) has hardwood floors
