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.

Our small cottage has a very narrow attic entrance. Denis from Attic Pros was willing to try and was able to enter to clean, vacuum, and replace the old insulation. Very professional, access areas were well shielded and protected. Powerful vacuum and clean up well after themselves.

Tom Best came to our house to give us an estimate on new insulation. He was on time, very thorough and provided a detailed very reasonable estimate within an hour of his visit. What more could you want?

David from Attic Pros was professional, knowledgeable, and thorough. He clearly explained the extent of our rodent problem in the attic and showed us detailed photos and videos so we could fully understand the damage. He took the time to explain exactly what the rodents had caused and walked us through how the repairs would be completed. David was friendly, patient, and easy to talk to, making the entire process much less stressful. We really appreciated his honesty and professionalism.

We cannot say enough good things about Attic Pros! From start to finish, it was a great experience. We initially called for attic, crawl space and duct cleaning, as well as rodent proofing (sealing vents, etc). Samim came out and did a very thorough evaluation, showing us dozens of photos of areas that needed attention. He also recommended new insulation, which we hadn’t considered and told us our dryer vent needed repair. It took us a few weeks to schedule, during which time Samim followed up periodically, never pushy, always answering our questions and providing more info. His professionalism and knowledge was a huge reason why we chose to work with Attic Pros. On the day of the job, Osman and crew cleaned the attic and crawl space and installed new installation, while Douglas repaired the dryer vent and Kevin cleaned the ducts. They did an amazing job sealing off the work areas and keeping the house clean, despite it being very messy and grueling work! They spent about 3 hours vacuuming the attic and another half a day sweeping the crawl space by hand. Their attention to detail was above and beyond what we expected. We were sooo impressed! And Samim’s recommendations were spot on - our dryer is much more efficient now and we noticed the house was cooler within hours of the new insulation being installed (it was the height of summer). We’d use and recommend them again and again!

We had a great experience with Attic Pros Oakland during our estimate. Tom was friendly, professional, and very accommodating with our questions and schedule. He took the time to inspect both attic areas thoroughly, explain what he found, and walk us through the recommended scope in a clear, no-pressure way. We appreciated how organized and respectful he was in our home, as well as the detailed estimate that helped us understand the work being proposed. Based on our experience so far, we would definitely recommend Attic Pros Oakland to anyone looking for attic cleaning, insulation, air sealing, or rodent-proofing services.

(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.
