Getting your insulation quantities wrong costs you money. Too much material and you waste cash. Too little and your crew stands around waiting. Our insulation estimating services give you accurate square footage, correct thickness, and the right R-value for every surface: walls, roofs, ducts, and pipes. ALM estimating delivers fast takeoffs so you can bid with confidence. No guessing. No rework.

Insulation estimating is the process of measuring and calculating all the insulation material needed for a project. This includes walls, roofs, floors, ducts, and pipes. It also includes the thickness of the material and the R-value required by the specs.
Many people think insulation is just a simple area calculation. But that is not correct. Different materials cover differently. Spray foam behaves nothing like fiberglass. A rigid board needs its own calculation method.
ALM Estimating insulation takeoff services handle all of that for you. Our expert team looks at every surface that needs thermal or acoustic protection. Then we deliver a complete quantity report you can bid from immediately.
Every estimate we deliver includes the following line items. Nothing is left for you to guess.
Accurate estimating does three things for your business.
You buy what you need, not more.
You meet the R-value required by code.
Less waste means more profit left on the table.
We have done takeoffs for nearly every type of insulation project. Here are the most common ones.
Houses, townhomes, apartment buildings, Office buildings, retail stores, hotels, and schools.
Warehouses, manufacturing plants, cold storage, and processing facilities, Industrial Construction, High Rise Buildings, Military Construction, Municipal Buildings and Offshore Construction etc.
Flat walls and attic floors are one thing. But the complicated jobs: pipes, tanks, turbines, steam generators that is where accurate estimating separates profit from loss.
Steam, chilled water, solar thermal, refrigerant. Hot and cold.
Boilers, heaters, tanks, vessels, heat recovery steam generators (HRSGs).
Industrial exhaust, HVAC supply and return, kitchen grease ducts.
Mechanical rooms, generator enclosures, multi-family walls. We measure by square footage and track material density.
Heat tracing cable, controllers, sensors, and insulation over the top.
Structural steel, wall penetrations, firestop systems.
Valves, flanges, heat exchangers, turbines. We count each blanket by size, thickness, and material type.
Cryogenic tanks, hot water storage, chemical holding tanks. We measure curved surface area, flat math does not work on a cylinder.
Weather barriers, mastics, coatings. Plus access platforms, ladders, and walkways for safe equipment access.
Gas turbines, steam turbines, generators.
Industrial furnaces, biomass boilers, coal and gas-fired generators.
Not all insulation works the same way. We estimate every major type so you do not have to guess.
Fiberglass and mineral wool. Comes in rolls or pre-cut panels.
Rigid panels used on foundation walls, basements, and exterior sheathing. We measure board feet and account for seams, fasteners, and R-value per inch.
Cellulose or fiberglass blown into attics and wall cavities. We calculate by bag count and target density.
Closed cell or open cell. Used for rim joists, crawl spaces, and hard-to-reach areas. We estimate by board foot and track thickness carefully because spray foam is expensive to over-order.
Foam forms that stay in place after concrete pours. We estimate the foam panels, ties, and reinforcement. Not every estimator does this. We do.
Pre-fabricated panels with foam between two structural facings. We estimate by panel count, square footage, and connection materials.
Foil-faced products that reflect heat. Used in attics and crawl spaces. We estimate by square footage and account for air gaps because radiant barriers need air to work.
Dense fiberboard used for sheathing and sound control. We estimate by sheet count and thickness.
Ductwork needs insulation to prevent energy loss. Pipes need insulation to control temperature and prevent condensation. We estimate linear feet for pipes and square footage for ducts. We also track thickness and facing type.
We use current SMACNA productivity standards and adjust for your project location. You get real numbers, not national averages.
We do not guess. We measure. We count. We verify. Then we deliver.
We read every note, every detail, and every schedule. We look for callouts about insulation thickness, R-value, and material type.
We mark every surface that needs insulation. Walls, roofs, floors, ducts, pipes, equipment. Nothing gets missed.
Area times thickness gives you volume. For batts, we use square footage. For spray foam, we use board feet. For pipe insulation, we use linear feet.
We apply realistic labor rates based on the material type and install conditions. Spray foam takes different labor than fiberglass batts. We account for that.
You receive an Excel file with all quantities, a cost summary, and marked-up drawings. You can use it to bid immediately.
Here is a real example of what one of our estimates looks like. Numbers are for illustration only. You get a breakdown like this for every project. No hidden numbers. No vague totals
This guide helps you understand what thickness delivers what R-value for common materials. Use it as a reference when you review your own bids or when you talk to customers.
3.5 inches ≈ R-13 (typical wall)
6.25 inches ≈ R-19 (typical floor or attic)
9.5 inches ≈ R-30 (typical ceiling)
1 inch ≈ approximately R-6 to R-7
2 inches ≈ approximately R-13 to R-14
3 inches ≈ approximately R-20
1 inch ≈ R-5 to R-6
2 inches ≈ R-10 to R-12
4 inches ≈ R-20 to R-24
1.5 inches ≈ approximately R-6
2 inches ≈ approximately R-8
3 inches ≈ approximately R-12
Knowing these numbers helps you catch mistakes in your own takeoffs. If a wall says R-13 but the thickness is wrong, you know something is off.
We measure the square footage of every surface that needs insulation. Then we multiply by the specified thickness to get volume. For pipes, we measure linear feet. For ducts, we measure the outside surface area.
Material type, thickness, R-value, and installation location all matter. A spray foam wall is different from a fiberglass attic. Duct insulation requires different math than pipe insulation. We account for every variable.
We need your digital drawings (PDF or CAD), any specifications or notes about R-value and material type, and your project location for labor pricing. That is it.
Our estimates are accurate enough to bid from. We do not round up or guess. Every quantity is measured directly from your drawings. If we are unsure about a detail, we flag it before delivering the estimate.
Yes. We estimate acoustic insulation for walls, ceilings, floors, and mechanical rooms. The process is the same as thermal insulation, but we pay extra attention to thickness and density.
