R13 fiberglass batt insulation, typically used in walls and floors, is 3 5/8 inches thick, according to Energy.gov. Insulation needs and the effectiveness of the insulation vary depending on climate and material.
What is thicker R13 or R19 insulation?
There is a direct relationship between the amount of insulation and the amount of heat transfer. The bigger the R value, the better the insulation is at slowing down the heat transfer. So R19 is better insulation than R13, and R30 is better than R19. The larger the R value, the better the insulation value.
What is R13 insulation for?
R13 batt insulation is typically used to attenuate sound in interior wall cavities. It is akin to a large blanket, designed specifically to fill a wall, floor, or ceiling cavity. Our R13 insulation measures 3.5in thick and is designed specifically for 2×4 framing.

What insulation fits in 2×4 walls?
Insulation for 2×4 Walls In most wall applications, you will use R-13 or R-15 kraft-faced fiberglass insulation rolls for these two-by-four stud walls. While rated differently, these two types of insulation are close enough in thickness that they can both fit into modern two-by-four wall systems.
Is R13 insulation enough?
Efficiency However, Insulation helps you to control the temperature of your home. From our earlier discussion, we already know that a higher R-value works more efficiently. Therefore, if you’re looking for energy-efficient insulation for your home, then we recommend you buying R15 over R13.
How thick is r12 insulation?

What is the thickness of batt 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. That means the batt labeled R-19 really gives you R-18 in a closed cavity.

What’s the difference between R15 and R19 insulation?
The heat resistance of R15 insulation is slightly larger than the heat resistance of R13 insulation. However, both options are suitable for 2×4-inch walls, and you should opt for an R19 insulation material if the walls in your home are 2×6-inches.
Can I put 2×6 insulation in a 2×4 wall?
