What insulation fits in a 2×6
Insulation for 2×6 Walls Use R-19 or R-21 kraft-faced fiberglass insulation for two-by-six (2×6) walls.
This combination ensures that the insulation is neither too loose nor too tightly packed within the walls.

What is R-13 insulation used for
Two-component closed cell spray polyurethane foam insulation provides R-values as high as 6.5 per inch of thickness, which means that you can achieve R-13 in a space as thin as 2.0 inches. It also blocks air leaks and drafts better than other insulation materials.

What is the R-value of a 2×6 stud wall with typical batt insulation
Thermal Control The installed insulation R-value for 2×6 fiberglass batt ranges between R-19 and R-21. When blown or sprayed cellulose insulation is used, the R-value is typically R-20 for 2×6 walls.
How much insulation can you get in a 2×6 wall
Fiberglass and rock wool batts – 2×4 walls can hold R-13 or R-15 batts; 2×6 walls can have R-19 or R-21 products. Generally, batt insulation is the least expensive wall insulation material but requires careful installation for effective performance.
What R rating insulation do I need
Depending on where you live and the part of your home you’re insulating (walls, crawlspace, attic, etc.), you’ll need a different R-Value. Typical recommendations for exterior walls are R-13 to R-23, while R-30, R-38 and R-49 are common for ceilings and attic spaces.
Should you insulate between roof rafters
Insulating between the joists of your loft will keep your house warmer, but make the roof space above colder. This means pipes and water tanks in the loft space could be more likely to freeze, so you will need to insulate them.
What is the best ceiling insulation
Spray foam insulation is a new and incredibly effective insulation solution. Spray foam insulation is applied by spraying a solution in the ceiling, floor or walls which bubbles into a thick layer of insulation. It generally has a higher R-value than traditional forms of insulation.
Is R-13 insulation good
Although the U.S. Department of Energy rates R-13 insulation as “good” for use in walls in southern areas of the country, it rates R-19 insulation higher, designating it as “great.” That is because R-19 insulation provides more thermal insulation than R-13 does.

Can you use R13 in 2×6 walls
No, it will not be rendered ineffective. You will have R13 walls. If it’s free and you have enough I would do 2 layers. Kraft facing on batts is flammable.
What is the cheapest insulation to buy
Fiberglass batts are typically the cheapest insulation, but a loose corner or tear can diminish the insulation quality.
What is the R-value at the stud
1.25 per inchHowever, wood wall studs generally lower the r-values of your insulation. The r-values of wood are specified as 1.25 per inch.
Can you over insulate a house
It is possible to over-insulate your house so much that it can’t breathe. The whole point of home insulation is to tightly seal your home’s interior. But if it becomes too tightly sealed with too many layers of insulation, moisture can get trapped inside those layers.
Is R 15 better than R13
Is R15 better than R13? Answer: There isn’t much difference between R13 and R15. However, higher R values offer higher performance. Therefore, in the case of efficiency, R15 is better than R13.
Can you use 6 inch insulation in a 4 Wall
Could I use 6″ in a 4″ cavity without problems? Short answer is yes. You will get slightly more total R value using the 6 inch batt stuffed in the 4 inch volume. Not as much as 6 inch batt in a 6 inch space though.
How thick is 2×6 insulation
Here’s something you may not know. The standard R-19 fiberglass batt is 6.25″ thick. If you put that batt in a closed 2×6 wall, it will be compressed 0.75″ because a 2×6 is 5.5″ deep.
Is it better to insulate ceiling or roof
Saving energy costs by preventing heat loss due to heat conduction. Preventing the roof from accumulating moisture damage. Ease of construction- insulating the ceiling can be easier than insulating the roof, particularly with older homes.
