Why It Matters
The Straightforward,
Cost-Effective Insulation
Batt insulation is the familiar option — pre-cut panels (or blankets) of fiberglass or mineral wool, sized to fit between standard-spaced joists and studs. In open, accessible cavities like new-construction walls or a clear attic floor, it goes in quickly and delivers reliable, code-level R-value at a cost-effective price, which is why it's one of the most widely used insulations there is.
The catch is the fit: batts only perform when they're cut and set snugly, with no gaps or compression. That's the difference between a batt job that works and one that doesn't. If your space is irregular or hard to reach, blown-in options fill better — compare with cellulose and fiberglass roll, or see our full attic insulation installation service.

Why Batt
What Makes Batt
a Popular Choice
The properties that make batt insulation a go-to for the right spaces — all inherent to the material.
Fast in open cavities
In new construction or any accessible, standard-spaced framing, batts drop in quickly — a straightforward, efficient install.
Code-level R-value
Batts come in set thicknesses that deliver standard R-values (for walls, floors, and attics), so it's easy to hit the target for your space.
Fiberglass or mineral wool
We install fiberglass batts or mineral (rock) wool — which adds fire resistance, sound dampening, and better moisture tolerance.
Faced or unfaced
Faced batts include a built-in vapor retarder for the right applications; unfaced batts suit others. We use the correct type for the location.
Proven and widely used
Batt is a long-established, code-recognized insulation — a dependable choice when the space suits it.
Is It Right for You?
When Batt Is
the Right Choice
Batt shines in the right spaces — and struggles in others. We'll confirm the best fit at your free assessment.
New construction or open walls
When the framing is open and accessible, batts are quick to install and a cost-effective way to insulate before the walls close up.
Standard joist & stud spacing
Batts are sized for standard 16- or 24-inch spacing, so evenly framed cavities are exactly where they fit best.
An accessible, clear attic floor
A clear attic with open joist bays is easy to lay batts into for a straightforward R-value upgrade.
You want a budget-friendly option
If cost is a priority and the space suits it, batt delivers solid performance for less than many alternatives.
You want fire or sound benefits
Mineral wool batts add fire resistance and sound dampening — a strong pick for that, and for interior walls.
Fewer obstructions to work around
Batts perform best where there's little wiring, plumbing, or irregular framing to gap around — otherwise blown-in fills better.
How We Work
Our Batt Insulation Installation Process
With batt, the snug, gap-free fit is the whole game. Here's how we handle every install.
Free assessment
We inspect the space, check the framing and current R-value, and confirm whether batt is the right fit or a blown-in option would perform better.
Select material & R-value
We recommend fiberglass or mineral wool and the right thickness to hit the target R-value for your walls, floor, or attic.
Prep & remove if needed
If existing insulation is old, compressed, or contaminated, we remove and haul it away so the new batts sit on a clean surface.
Cut & fit snugly
We cut the batts to fit and set them snugly and gap-free — around wiring and boxes, not compressed — so they actually perform.
Verify & clean up
We confirm full, even coverage at the target R-value, clean up completely, and walk you through the finished job.

We had Samim come out to our house. He was so kind, fair, and professional, and put me at ease following an exorbitant price gouging experience. I highly recommend Attic Pros and if you can, ask for Samim. You will be happy with the quality of their work as well.

Attic Pros recently replaced my old insulation with new insulation. I called them back today 3 weeks later to check on the Rat traps they placed in the Attic as I experienced an unusual odor coming from the air vents throughout the house. Jose of Attic Pros responded and was a very upbeat chearful person who explained what he was going to do prior to going into the Attic to check on the Rat Traps. Fortunately the traps were still set with no activity. Jose took photos ( see attached) while he was in the Attic which showed no activity. I later found that the odor was a filter in the hvac systrem which had debris which causec the odor. Jose completed the inspection by walking around the house and inspecting the outside vents which I appreciated. All the Attic Pro employees which I have come into contact with are Professional, friend;y an do a thouough job completing whatever jobs in their field are requested.

(800) 543-0382It depends on the thickness and material. Batts come in standard thicknesses that hit set R-values — commonly around R-13 to R-15 for 2x4 walls, R-19 to R-21 for 2x6 walls, and R-30 to R-38 for attics. We calculate the right R-value for your space and climate and select the batt thickness to match.
Both are batt insulation, but mineral (rock) wool is denser — it's more fire-resistant, dampens sound better, and tolerates moisture better than fiberglass, though it typically costs a bit more. Fiberglass batts are lighter and the most budget-friendly. We'll recommend the right one for the location.
It comes down to the space. Batts are fast and cost-effective in open, standard-spaced, accessible cavities. Blown-in cellulose or fiberglass fills better around obstructions and in irregular or hard-to-reach spaces, and air-seals as it fills. For a retrofit or a cluttered cavity, blown-in often wins; for open framing, batt is efficient. See our cellulose and fiberglass-roll pages to compare.
It depends on the application. Faced batts have a built-in vapor retarder that's needed in some assemblies (and faces the conditioned side), while unfaced batts are used in others or as an added layer. Using the correct type in the correct orientation matters for moisture control — which is part of doing it right.
A lot. Batts only deliver their rated R-value when they're cut to fit snugly, not compressed, and set gap-free around wiring and boxes. Gaps and compression are the most common reason a batt job underperforms — which is exactly what careful installation avoids.
Sometimes — unfaced batts can be layered over existing insulation that's still in good condition to boost R-value. If the existing insulation is compressed, damaged, or contaminated, we remove it first so the new insulation performs.
Most residential batt installs are completed in a single visit. Timing depends on the size of the area, the framing, and whether old insulation needs to come out first. We'll give you a clear timeline with your estimate.
Fiberglass can irritate skin and airways, which is exactly why it's worth having installed by pros with the right protective equipment and technique rather than doing it yourself. We handle the cutting, fitting, and cleanup so you don't have to deal with the fibers.
