Batt insulation being fitted between joists

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.

  • Cost-effective, proven insulation
  • Fast to install in open cavities
  • Reliable, code-level R-value by thickness
  • Fiberglass or mineral wool options
  • Fit snugly and gap-free for real performance
  • A clean, straightforward upgrade

What Makes Batt
a Popular Choice

The properties that make batt insulation a go-to for the right spaces — all inherent to the material.

Cost-effective

Batt is among the most affordable insulation materials, which makes it a common choice for walls, attics, and crawl spaces on a budget.

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.

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.

Not sure whether batt or a blown-in option fits your space? Book a free assessment and we'll measure your cavities, compare the materials, and recommend the best fit — no pressure.

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.

UPDATE: I really appreciate the company followed up after my concerns were raised. They took accountability for what happened, handled the situation professionally, and offered to fix all the issues. Their responsiveness and willingness to make things right completely changed my impression, and I’m happy to update my review to 4 stars. They ultimately completed the job, but the overall experience was far from hassle-free. During the process, they damaged our ceiling and later repaired it, though the result was not fully satisfactory. There were multiple mistakes along the way, both in the actual work and in billing, which meant we had to stay very involved to ensure nothing was missed. Communication was also a challenge. Our consultant, Tom, was not as responsive as expected, especially given how busy schedules can be in the Bay Area. We often had to follow up multiple times to get updates or have issues addressed. Overall, while the job was eventually finished, the process required more oversight and effort than it should have. If I were to go through this again, I would choose a different company.

Shah turned my experience around from a bad one to a good one in the very beginning. Aleksandra at the office answered and addressed all my questions and concerns very thoroughly. Jose who did the rodent proofing, answered all my questions and took his time going through the crawlspace and making sure he found and covered all potential access points for rodents into the crawlspace. He was very patient and thorough.

It 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.
