That s how the barrier is made effective.
Faced insulation attic floor.
Install batting between the attic s floor joists.
Can i place unfaced batting and then place a small walkway.
Roll insulation is best for floors ceilings and roofs with a long joist or rafter bays and for tall walls.

Plan to pull up the flooring and layer new.
It s also important that there be no air pockets in the insulation as this is where the cold spots spring up in rooms.
On the attic floor i wan to lay some flooring and a small walkway.
It is important not to mix them nor use the wrong faced insulation product for each task.
Mostly paper faced insulation is the best choice for neophytes in insulation installations.
Start with the attic floor.
Using cut 3 4 plywood.
R value measures how resistant types of insulation are to heat flow.
Insulation is rated by its r value.
But if the floor is covered in plywood you can t stuff enough insulation beneath it to do the job sufficiently not even in warm climates.
All kraft faced insulation is easy to cut with a sharp utility knife or insulation knife.
Kraft faced or paper faced insulation comes in batts and long rolls.
Insulation decreases the amount of heat entering from outside when it s hot and traps warmth inside when it s cold.
If the attic doesn t have any existing insulation use faced insulation with the paper facing toward the heated living space.
R values vary based on the type thickness and density of the insulation material.
I live in the sacramento valley area which gets very hot and dry in the summer doesn t get to cold in winter but foggy damp days in the 30 3 and 40 s.
Faced insulation products not only use paper they can also use aluminum foil vinyl and even aluminum paper.
Faced insulation has flanges on the outside of the batt that need to be stapled to the wall studs and joists.
I am remodeling a shower stall and going to re tile when i did the demo i noticed the insulation was faced insulation and the paper was facing the outside.
However when adding multiple layers of insulation you want to make sure that only one layer has faced and that the facing does not lie against the second insulation layer.
If there is already insulation between the joists increase the r value by installing unfaced roll insulation right on top.
Insulation facing is a moisture or vapor barrier so it only makes sense to use faced insulation in your crawl space.
The batting material must be faced and at least as thick as the joists are wide so the batting is nearly flush with the top of the joists.
The batts are precut to fit into cavities on standard 8 foot high walls.
Without stapling moisture still has a path into the room.
Because the simplest and cheapest way to insulate an attic is to add material to the floor.
When to use paper faced.
