The cost to install batt insulation is one of the first questions homeowners ask when planning an energy-efficient upgrade or a full remodel. At CountBricks, we tackle that question with data-driven accuracy, leveraging real-time material pricing, regional labor rates and project scope captured through voice conversation. The result is an on-the-spot estimate that demystifies insulation expenses and allows residential contractors to move forward with confidence.
• Affordability compared to spray foam or blown-in
• Rapid installation keeps schedules tight
• Fits standard stud bays, joists and rafters
• Delivers consistent R-values when installed correctly
Because batt insulation is so common, you might assume pricing is straightforward. In reality, costs fluctuate daily based on fiber type (fiberglass, mineral wool or natural fiber), thickness, vapor barrier options and regional labor markets. CountBricks tracks all of these variables and updates estimates automatically—no spreadsheets, no guesswork.
Fiberglass batts are typically the lowest-cost option, while mineral wool can run 25-40 % higher but offers added fire and sound resistance. Natural fiber batts may climb another 15 %. CountBricks pulls current supplier pricing every morning so your estimate reflects today’s reality, not last quarter’s flyer.
Building codes in colder climates demand higher R-values. For example, upgrading from R-13 walls to R-21 can add 60-70 % to material cost but may qualify homeowners for local rebates that CountBricks flags automatically during estimate generation.
• Cathedral ceilings increase ladder time
• Non-standard stud spacing introduces waste
• Existing finish removal may be necessary in remodels
CountBricks’ voice assistant asks clarifying questions and adds line items for demolition, disposal and air sealing so your proposal covers the full scope.
Residential labor pricing can vary by 30 % between metro and rural areas. CountBricks ties every task—cutting, fitting, stapling, clean-up—to region-specific wage data, keeping your margins intact without overbidding.
Walls (per square foot)
• Fiberglass batt R-13: $1.25 – $1.80
• Mineral wool batt R-15: $1.60 – $2.25
Attics (per square foot)
• Fiberglass batt R-30: $2.00 – $2.85
• Mineral wool batt R-38: $2.65 – $3.50
Basement Ceilings (per square foot)
• Fiberglass batt R-19: $1.75 – $2.40
These ranges include materials and installation but exclude demolition or specialty vapor barriers. Use them for quick ballpark conversations, then open the CountBricks app to deliver a precise digital proposal in minutes.
1. Launch CountBricks on mobile or desktop and start a voice session.
2. Describe the area: “1,200 square feet of 2×6 exterior walls, remove old R-11 and install R-21 mineral wool.”
3. CountBricks parses the dimensions, pulls updated material pricing and regional labor.
4. Adjust insulation type or R-value on screen—pricing updates instantly.
5. Generate a branded proposal PDF, complete with acceptance e-signature and payment schedule.
The same data flows directly into your invoice once the homeowner signs, eliminating duplicate entry and ensuring profitability remains intact from takeoff to final payment.
• Up to 15 % utility bill reduction when walls and attics are brought to code
• Enhanced indoor comfort and noise control
• Improved appraisal value for energy-efficient homes
CountBricks proposals highlight these benefits so homeowners see beyond the line items and understand the long-term return on investment.
• Always include air sealing and vapor barrier costs; callbacks for condensation issues erode profit fast.
• Suggest mineral wool in garages or shared townhouse walls for superior fire ratings.
• Offer an “energy upgrade package” pairing batt insulation with attic ventilation—CountBricks bundles the tasks and applies multi-line discounts automatically.
In materials, yes. But CountBricks factors in regional incentives that can offset the premium and occasionally make the upgrade cost-neutral for the client.

A remodeling contractor in the Midwest approached CountBricks to estimate the cost to install batt insulation throughout a 2,400 sq ft ranch. The home had original R-11 fiberglass in the walls and no attic insulation at all.
• Remove existing drywall in living area (650 sq ft)
• Install R-21 mineral wool in all exterior walls (2×6 framing)
• Lay R-38 fiberglass batts between rafters
• Add Class II vapor retarder
1. Labor: 64 crew hours at prevailing wage = $3,680
2. Material: 1,180 sq ft R-21 mineral wool + 1,200 sq ft R-38 fiberglass = $3,240
3. Demolition & disposal: $750
4. Air sealing package: $420
Total cost to install batt insulation: $8,090
CountBricks flagged a state rebate of $0.25 per square foot for upgrades over R-19, instantly reducing client cost by $600 and helping the contractor land the job.
• Project completed two days ahead of schedule thanks to precise material ordering
• Blower-door test showed 22 % reduction in air leakage
• Homeowner reports 30 % lower heating bills in the first winter
