Answer: 
I had to learn the hard way, actual experience. A single bat measures 22" X 24" X 53". They also come bundled in a 4 pack, which measures 44" X 25" X 52". I have an older 10ft cargo trailer which measures 5' X 10'6" X 4' 7" high. Standing the bats on end you can squeeze in 5 bundles or 15 bats. Hopefully this will help somebody in the future.

Answer: 
The insulation type you choose for your attic should be based on what is most convenient for you. This means convenience for transporting and convenience for installing in your unique space. Using fiberglass batts may be a little more labor intensive as they are essentially pieces that need installing one after the other. These are sometimes best for vertical walls.
Many installers prefer to use rolls Read More
The insulation type you choose for your attic should be based on what is most convenient for you. This means convenience for transporting and convenience for installing in your unique space. Using fiberglass batts may be a little more labor intensive as they are essentially pieces that need installing one after the other. These are sometimes best for vertical walls.
Many installers prefer to use rolls as they are continuous and fast to fit in between the floor joists. The blown-in Atticat Insulation is an example of personal preference. Many installers prefer the ease of using the machine to blow the fiberglass across the floor.
When choosing the best option for you, it is most important to determine your local code requirements pertaining to the recommended R-value and vapor barrier placement for your region.

Faced? Non-faced? Retrofit insulation to truss-base-stringers?

This question is from R-38 Kraft Faced Insulation Batts 24 in. x 48 in.
Asked by
Lacey, WA
Read all my Q&A
January 8, 2016
We're in a heating-region, Coastal Pacific NW.
Usually, Kraft-facing goes on the room-side [warmed] of the joists or studs.
BUT...Existing attic insulation in our trusses, which we planned to go on top of, without disturbing that, doesn't require facing....or does it?
I have gotten mixed advice:
..... 1. "Remove old insulation, place new Kraft-facing down towards the tempered-space-ceiling, with non-faced side towards the attic, then use old insulation to put on top of the new stuff".
..... 2. "Kraft facing can't retro-fit between existing attic joists; only use non-faced".
..... 3. "Must have facing, to prevent the batts from deteriorating from air exposure".
Really? What? Fiberglas insulation batts or rolls, deteriorate when exposed to attic air??
Is there actually a definitive answer on the Kraft Facing??
Or has no one really definitively figured it, because the answer is such a movable target?
Or is the answer really arbitrary, depending on which official one talks with?
There's the argument about Dew-Points within insulated walls or ceilings:
With ANY insulation, a "dew-point" within the mass of the insulation, is where cold meets warm temps. That's where moisture can condense, concentrate, and cause mold....So, placing the Kraft barrier or vapor barrier, on the warmed-side of a wall or ceiling, supposedly prevents moisture moving from the living space, into the insulation, thereby helping decrease moisture there, helping prevent condensate within the insulation thickness.
On the other hand....using no vapor barrier, in a dampish climate, could allow moisture vapor to move or equalize through the thickness of the insulation..it will do that just from humid air...will still have a dew-point though, unless thick enough, or unless using foam board insulation.
IF the insulation is thick enough, the dew-point can be diffused, because of temperature gradient in thicker insulation is more of a gradual transition, instead of forming a dew-point--yeah?
Borated fluff insulation, has advantage: borate inhibits mold growth, as well as being fire-retardent.
But fluff can't go inside walls that already have old insulation in them.
And, thinner walls can't be loaded with enough thickness of current insulations, to prevent a dew-point by adding thickness...unless the walls are furred-out to make them thicker.
SOooo...back to the question...
What about those Kraft-facings? Home Depot apparently does NOT have Un-faced R-38 batts--only faced. ...Looks like their maximum is R-30 Un-faced batts?
CAN Kraft facings be removed?
Or does that ruin the batts?
Should we? Or???

Answer: 
Your local code will determine which way the Vapor Retarder / Kraft Facing should face for your region. Typically the vapor retarder will face the "warm in the winter" side for most cold winter climates, however again, code dictates the correct placement for your region. Also, Kraft Facing cannot remain left exposed because it is considered combustible. It must be covered by a 15 minute thermal barrier, Read More
