Roll insulation is a type of insulation that uses rolls of material to insulate a building. It is usually installed in walls, roofs, and floors. batt insulation is a type of thermal insulation made from fiberglass batts. batt insulation is usually installed in ceilings and walls.

Batt vs. roll insulation – what’s the difference?

  • Batt insulation is manufactured in a rectangular or bat-like shape that is filled with a thermosetting foam.
  • Roll insulation is manufactured in a long, cylindrical shape and is then cut into thin, wide sheets.
  • Batt insulation typically offers better thermal performance than roll insulation. It insulates better, lasts longer, and provides superior sound and fire protection properties.
  • However, roll insulation costs less per inch of insulation thickness and offers better flexibility for designing insulated structures.
  • Both types of insulation are easy to work with and can be installed in various configurations.


Batt insulation is made from recycled materials, making it a good choice for people who want to help the environment. Roll insulation, on the other hand, is made from compressed foam and can be more expensive but is also more durable.

Batt insulation is usually less expensive than roll insulation but doesn’t offer as much thermal efficiency. Overall, batt and roll insulation both have their advantages and disadvantages; it depends on individual needs and budget.

Shapes and sizes

Roll insulation has a greater length than batt insulation, so there is a significant variation in size. Pre-cut batt insulation comes in equal-size pieces. Batt-type insulation comes in a variety of lengths, with the average being 46 to 96 inches, depending on the wall height.

For huge commercial rolls, average length is 17 feet to 80 feet of roll insulation. Depending on the R-value of the product, the thickness of each insulation type varies. Both batt and roll insulation come in a 15-inch to 23-inch standard width.

Wall insulation is frequently supplied in 2inch by 4-inch and 2by 6-inch wall cavities, while roll insulation allows for complete installation without the need of making cuts. When using roll insulation, you may calculate the height of a wall cavity and cut it accordingly.

Batt insulation is a type of insulation that is often used in the form of rolls. It is commonly used in areas where there is a lot of movement, such as in the attic or on the roof. Roll insulation, on the other hand, is installed in walls and ceilings like carpeting. Batt insulation typically lasts longer than roll insulation but is less expensive.

Both types of insulation provide thermal insulation, which helps keep heat inside your home and out of the air. However, batt insulation can also be used for soundproofing purposes. Overall, batt insulation offers several benefits over roll insulation and can be a cost-effective choice if you are looking for an effective insulating solution for your home.


The cost of batt and roll insulation varies. The insulating material, size, and installation expenses of each gadget all affect the cost differential.

In comparison to $0.80 to $1.00 for a square foot of roll insulation, bat insulation costs between $0.12 and $0.60 per square foot. You should consider that rolls are often sold as full rolls whereas batts seem as solitary pieces offered separately or in a set, even though the price differences may appear minor.

Depending on the insulating material and other variable costs, a full roll of insulation costs $20 to $90. A full set of batt insulation, on the other hand, consists of 5 to 11 individual components and costs between $200 and $600 depending on the size, sort of material, and any extra variable labor costs.

When working on huge surfaces, batt insulation is somewhat more costly since each piece costs somewhat more than the same-size rolls of roll insulation.


Batt insulation is typically installed in rolls and can be more cost-effective than roll insulation. However, batt insulation does not insulate as well as roll insulation in cold environments. In addition to its cost-efficiency, batt insulation also provides better thermal performance than roll insulation.

Roll insulation is a more expensive option but offers better thermal performance. Overall, batt and roll insulation have their advantages and disadvantages and should be used according to specific needs and requirements.


Without taking into account the insulation material, surface size, or installation procedure, it may be difficult to determine the efficacy of an insulation type.

When putting in place a limited surface size, such as when applying insulation to a small room, batt insulation is more effective. When dealing with huge surfaces and high walls, roll insulation is invaluable since it can cover wide areas.

When working alone in a DIY environment, batt insulation is a better option since batts may simply be placed and fitted. Spaced that need teamwork or have little obstacles like electrical cables, water lines, and so on are better suited to rolls.

In comparison to using batt insulation, you may cover up uneven areas and gaps with ease by using rolls.


The R-value per square inch of batt and roll insulation varies slightly. The variations might be due to the varying R-values of the insulation materials, each with its own unique R-value per square inch.

The R-value range for bat fiberglass is 10.8 to 11.9 per 3 ½ inches, whereas mineral wool has an R-value of 19 to 21 per 6 inches, among other things. Depending on the thickness and material density of the product, roll insulation has an R-value ranging from 3 to 21. Batt insulation has an R-value of roughly 3.1 to 3.4 inches per inch, whereas roll insulation has an R-value of roughly 2.9 to 3.8 inches per inch.

Differentiating between batt and roll insulation using R-values might not be the best metric. The capacity to completely seal gaps and air spaces over a broad area, on the other hand, may raise the R-value of roll insulation.

Which is better – batt or roll insulation?

Batt insulation is a type of insulation made from recycled newspaper. In general, it is more affordable than fiberglass insulation, but it can be more difficult to install.

Foam insulation made from recycled newspaper is known for its high R-value per inch of thickness, making it a popular choice among home insulation contractors. It’s feasible to insulate walls and attic with batt insulation using roll-in-roll-out (RIR) insulation insulated with fiberglass batt insulation. However, batt insulation offers better thermal performance and durability than fiberglass batt insulation.

Both types of insulation provide effective insulation against heat flow in buildings. However, batt insulation offers better overall energy efficiency due to its superior R-value per inch of thickness.

Hence, if you are planning to insulate your home or business with fiberglass batt insulation, it would be beneficial to consider the pros and cons of both types of insulation before making a choice.

Frequently Asked Questions

What are the benefits of batt and roll insulation?

Batt insulation is a type of insulation that uses batts. Batts are long pieces of insulation that are compressed together and then sprayed into the attic or wall cavities. Batt insulation is less expensive than other types of insulation, is effective at preventing heat loss, and can be used in a variety of applications.

Which type of insulation is best for my home?

When it comes to insulation, batt insulation is generally considered to be the best type. Batt insulation is made from fiberglass insulation, which is a two-part system: the batt and the sheathing. The batt insulation is attached to the sheathing using screws or nails, and then the entire assembly is wrapped in a thermal insulation material like fiberglass.

Compared to roll insulation, batt insulation offers greater thermal efficiency because it can trap more heat within its fibers. Additionally, batt insulation is more expensive than roll insulation, but it offers greater thermal efficiency and better moisture resistance. On the other hand, roll insulation is cheaper than batt insulation and it offers better moisture resistance.

Why are insulation batts more expensive than rolls?

Batts are more expensive than rolls of insulation because they are compressed and have a higher R-value. A batts has a higher R-value because its insulation capacity is greater than that of a roll of insulation. A batts will typically last around twice as long as a roll of insulation.


There are many types of insulation available that can help you achieve your insulation goals, such as foam insulation, cellulose insulation, and fiberglass insulation. Not only do these different types of insulation provide different benefits, but they also vary in terms of their installation process and material type.

With so many choices to pick from, it’s easy to understand why most homeowners would choose to include more than one type of insulation in their attic program.
