Buying a roll of R19 insulation is a common budget item for home projects. The price you’ll see depends on roll size, material quality, face paper, and whether installation labor is included. This article presents practical cost ranges in USD and explains the main drivers behind the final price.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Roll of R19 insulation (fiberglass) | $60 | $120 | $210 | Unfaced or standard faced rolls for walls or attics |
| Per-square-foot installed cost | $0.80 | $1.20 | $2.00 | Includes labor and permitting where applicable |
| Typical project size (bundle of rolls for 1,000 sq ft) | $480 | $1,200 | $2,000 | Assumes standard attic or wall cavity gaps |
| Labor (hourly, installer) | $40 | $60 | $90 | Per hour, regional variation applies |
| Delivery | $0 | $20 | $60 | Depends on distance and supplier |
Typical Price for a Roll of R-19 Insulation by Size
Buyers commonly pay in the range of $60-$210 per roll, with most residential projects landing near the $120-$180 mark for standard 15–16 inch wide rolls that cover wall or attic spaces. Assumptions: Midwest or Southeast markets, standard fiberglass bat insulation, typical faced or unfaced rolls, no curbside delivery surcharge.
Per-square-foot costs typically fall in the $0.80-$2.00 band when you include both material and labor. The widest swings come from roll width, length, and whether installation labor is needed or if a DIY approach is chosen. In homes with complex geometry, gaps, or existing moisture issues, expect toward the higher end of the range.
Breakdown of Costs in a Roll Insulation Quote
Cost components commonly appear in a formal quote. The table below shows the main parts and typical dollar ranges per project when insulating a standard attic or wall area.
| Cost Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials (R-19 fiberglass rolls) | $60 | $120 | $210 | Roll counts based on space; assumes standard 3.5–6.0 inch framing cavity |
| Labor (installation) | $100 | $360 | $900 | Hourly rates vary by region |
| Wraps, vapor barriers, and fasteners | $15 | $40 | $80 | Materials for doorways, corners, and penetrations |
| Delivery/Transport | $0 | $20 | $60 | Distance-based |
| Removal and disposal | $0 | $20 | $70 | Old insulation or debris handling |
| Permits or inspections | $0 | $50 | $150 | Region-dependent |
Assumptions: standard attic or wall retrofit, normal access, no moisture or mold remediation.
Key Variables That Shift the Final Price
Several specific factors can push the price up or down. Two notable drivers are the size of the project and the system type.
- Project size in square feet: Attics over 2,000 sq ft or walls with multiple levels typically require more rolls and longer labor, biasing costs toward the high end. Threshold: 1,500–2,000 sq ft often moves from mid-range to high-range pricing.
- System type: Installed bat insulation in standard cavities is cheaper than dense-pack or spray-in methods, which may be required for certain retrofit scenarios. Threshold: dense-pack or spray-in can add $0.60-$1.50 per sq ft extra material and labor.
- Access and prep: Forklift or crawlspace access, joist spacing, and existing wiring affect labor hours and waste handling. Impact: poor access adds 20–40% to labor time.
- Moisture or mold remediation: If present, removal and remediation add significant cost beyond standard insulation.
Regional Price Variations for R-19 Insulation
Price floors and ceilings differ by region due to labor rates and supplier competition. The table outlines typical regional ranges for material plus assumed standard installation.
| Region | Material (Roll) | Installed Cost per Roll | Notes |
|---|---|---|---|
| Northeast | $70-$130 | $200-$320 | Higher labor rates; common to include vapor barrier options |
| Midwest | $60-$110 | $140-$210 | Competitive pricing; good access |
| South | $55-$100 | $120-$190 | Typically lower installation cost; humidity considerations |
| West | $65-$120 | $150-$260 | Shipping and local demand impact |
Assumptions: standard 3.5–6 inch cavity depth, typical attic or crawl space retrofit, no major structural work.
Efficiency and Access Impact on Labor Time
Labor hours hinge on access and insulation efficiency. A straightforward attic with open bays can finish faster, while a retrofit in tight spaces or around obstructions increases labor. Labor often ranges from 2.5 to 8 hours for a typical 1,000 sq ft attic, depending on crew size and reach.
Formula example: labor_hours × hourly_rate = labor cost. For a 1,000 sq ft attic with 2 workers at $60/hr each, expect around 5 hours × $60 × 2 = <$600> for labor, excluding materials.
Per-Unit Details That Help a Budget
When planning, consider per-roll and per-square-foot quotes to compare offers fairly. The most common unit is the roll, but per-square-foot installed cost often provides a clearer picture for budgeting across rooms or levels.
| Pricing Unit | Low | Average | High | Notes |
|---|---|---|---|---|
| Per roll | $60 | $120 | $210 | Depends on width and length |
| Per sq ft installed | $0.80 | $1.20 | $2.00 | Material + labor |
Assumptions: standard 15–16 inch roll width, normal attic or wall installations, typical vapor barrier choices.
Ways to Lower the Price Without Compromising Performance
Cost control can come from scope adjustments, timing, and material choices. A few practical options that keep R-19 performance intact include batching projects by region, opting for unfaced rolls where appropriate, and scheduling during contractor off-peak times.
Practical steps: bundle insulation with other drywall or ceiling renovation needs to reduce mobilization fees; select standard width rolls rather than premium variants; verify access and plan for a single visit to reduce labor duplication. These choices can shave 10–25% from the total project cost in many markets.
Three Real-World Quote Scenarios
Below are representative quotes for different project scopes, illustrating how size and labor affect totals. These examples assume mid-range regional labor, standard attic installations, and basic materials only.

- Materials: $90-$150
- Labor: $400-$700
- Delivery/Disposal: $20-$40
- Total: $510-$890
-
Wall retrofit for 1,500 sq ft, dense-pack not used, standard vapor barrier
- Materials: $180-$320
- Labor: $1,000-$1,600
- Permits/Inspections: $0-$120
- Total: $1,180-$2,040
-
Combined attic and garage insulation, 2,200 sq ft total, mid-range access
- Materials: $260-$480
- Labor: $1,200-$2,000
- Delivery: $20-$60
- Total: $1,480-$2,540
Cost-Safety and Material Tradeoffs
Choosing the lowest material price may invite hidden costs from reduced performance or durability. For R-19, premium facings and moisture-resistant variants can lift cost by 10–25% but may reduce long-term energy losses. Weigh short-term savings against potential energy efficiency gains and comfort improvements over time.
Assumptions: typical US homes built in the last 20–30 years, standard insulation needs, no major weather events impacting installation windows.
What Affects Per-Roll Price Immediately
Several immediate factors determine the price you see at the store or in a contractor quote. Availability of rolls in your width, manufacturer rebates, and bulk purchase discounts can shift numbers by 5–15% quickly.
Tip: ask for an itemized breakdown and verify roll width and length so you’re comparing apples-to-apples across suppliers. A small misalignment in roll specs can create a meaningful price delta when multiplied by the number of rolls needed.
