Installing attic insulation on your own is not that difficult of a task. This article will lay out all the necessary steps and guidelines in attic insulation. Therefore, read on to find out how attic insulation (using loose-fill or fiberglass batts) are being done.
Before installing the insulation in the attic, you are advised to do some inspection around the attic. Most attics are unheated and unfinished, meaning the attic has no floor and it’s just joists and ceiling from the room below.

Attic insulation and attic ventilation cannot work without one another in the attic. The important thing is the ventilation has to be coming from vents, not from gaps around wiring or chimneys. Therefore, before installing attic insulation, you are encouraged to check for such gaps. If such gaps exist, what you can do is you can caulk around these gaps to cut drafts and to prevent insects, birds and animals from entering through these gaps.
To make long story short, the first thing that you do when you are up at the attic is, inspect the attic to see if there is any existing insulation around. If your attic already has some insulation in place between the ceiling joists, you will need to use the unfaced insulation batts. It’s very common some insulation batts come with a facing on one side that provides a vapor barrier. The unfaced insulation batts are the type that doesn’t have vapor barrier.
If there is already insulation in place in the attic, great! The next step is to inspect the existing attic insulation whether it is the faced type (with vapor barrier). Check that the vapor barrier is facing the right way . In this case, the vapor barrier has to be facing down, toward the heated house. If it’s not facing the right direction, you will need to flip it over so that the vapor barrier is installed properly. You can run a utility knife over it to break the existing insulation seal so that you can flip it over.
