Insulation estimating software for pipe, duct and building envelope

Insulation estimating software measures what gets insulated and prices it by material, thickness and labor. Mechanical insulation contractors take off pipe by size and length, fittings and valves, and duct and equipment by surface area, often importing the quantities from the mechanical takeoff; FastWRAP is built for that¹. Building insulation is measured as wall, roof and floor areas by R-value, which general takeoff tools such as PlanSwift and STACK handle with assemblies you set up³⁵.

What an insulation takeoff measures

Item	Unit	What to watch
Pipe insulation	LF by pipe size and thickness	Thickness changes with pipe size and service (chilled water, heating water, domestic hot, refrigerant), per the spec table.
Pipe fittings and valves	EA	Elbows, tees, valves and flanges take more labor than straight pipe. Count them or let the software convert them to equivalent lengths.
Duct wrap and duct board	SF	Surface area from duct size and length. Lined duct is usually in the sheet metal scope, not yours; confirm in the spec.
Equipment	SF	Tanks, heat exchangers, pumps and breeching, often with removable covers or jacketing.
Jacketing and finishes	SF / LF	PVC, aluminum or stainless jacketing on exposed or outdoor work adds a separate material and labor layer.
Wall, roof and floor insulation	SF by R-value	Batts, blown-in, rigid board and spray foam priced per area at a given thickness or R-value. Rigid insulation above a roof deck is often carried in the roofing estimate instead, so check the roof sections before counting it.
Spray foam	Board feet	A board foot is one square foot at one inch thick. Area times thickness in inches gives board feet.
Firestopping and sealants	EA / LF	Penetrations and joints, if they are in the insulation contract. Often split with other trades.

How an insulation estimate is built

Read the insulation spec: which systems are insulated, thickness by pipe size and service, jacketing, and what belongs to the sheet metal or general contractor.
For mechanical insulation, take off or import pipe by system and size from the mechanical takeoff, then fittings, valves and flanges.
Take off duct wrap and board by system and surface area, then equipment and breeching.
For building insulation, measure wall, roof and floor areas by assembly and R-value, excluding openings where the spec allows.
Apply thickness, layers and jacketing from the spec, and waste factors that match the product.
Add access (lifts, scaffolding), height and occupied-building factors, and any removal of existing insulation.
Price material from distributor quotes, apply labor by linear foot, square foot or board foot, and present by system.

What to look for in insulation software

Thickness by size and service

Specs that pick insulation thickness and material automatically from pipe size and system, matching the spec table.

Layered systems

Insulation plus jacketing, adhesive or paint calculated as layers, each with its own material and labor.

Import from the mechanical takeoff

Reuse pipe and duct quantities from the mechanical estimate instead of tracing the drawings twice.

Area assemblies by R-value

For building insulation, area takeoffs tied to assemblies by product and R-value with waste and labor, so a plan change updates the price.

Mechanical insulation vs building insulation estimating

Insulation estimating covers two different businesses. Mechanical insulation contractors work from the mechanical and plumbing drawings: pipe by size and service, fittings and valves, duct and equipment, with thickness set by the spec table and jacketing on exposed work. Their estimate follows the mechanical takeoff so closely that the fastest path is to import it; FastEST describes FastWRAP importing FastPIPE and FastDUCT takeoffs for exactly that reason¹.

Building insulation contractors work from architectural plans, sections and wall types: square feet of wall, roof and floor by R-value and product, plus board feet for spray foam. Any tool that measures areas and ties them to assemblies does the job; PlanSwift, for example, describes insulation assemblies by R-value, install method, material, labor and waste³. Residential spray foam crews often quote from site measurements in a field service app rather than from plans.

Recessed fixtures, heat trace and firestopping: where insulation meets the electrical work

Building insulation and lighting meet at every recessed fixture in an insulated ceiling. NEC 410.116(B) keeps thermal insulation from being installed above a recessed luminaire or within 3 inches of its enclosure, wiring compartment, driver or power supply unless the fixture is identified as Type IC⁷. When insulation goes into a ceiling the lighting design treated as unconditioned, fixtures that are not IC-rated need either a substitution, which changes the electrical bid, or dams and clearances, which change yours. Check the fixture schedule against the insulation sections, and agree the sequence with the framing contractor and the electrician so boxes and housings are in before the batts.

Heat trace is the mechanical version of the same overlap. Freeze-protected piping gets electric heat tracing under the insulation, and the electrical contractor feeds it: NEC 427.22 calls for ground-fault protection of equipment on branch circuits supplying the heating equipment, with an exception for some industrial processes⁸, and splices and terminations that remain outside the thermal insulation go in a box or fitting under 427.19(B)⁹. Your crew wraps over the tracing after it is installed and tested and keeps the power connections reachable, so the spec should say who installs the cable. The circuits show up as equipment connections in the electrical estimate.

Firestopping is the third overlap. If it is in your contract, every conduit, cable and tray penetration through a rated wall is a firestop item, and those are shown on the electrical drawings, not the mechanical ones. AmpCount does not measure insulation, but its counts of recessed fixtures by type can help check how many sit in an insulated ceiling.

Where insulation takeoffs go wrong

Using one thickness for all pipe when the spec table changes it by size and service.
Pricing fittings and valves as straight pipe, which understates labor on busy mechanical rooms.
Carrying duct liner that belongs to the sheet metal contractor, or missing duct wrap that is yours.
Forgetting jacketing and finishes on exposed and outdoor runs, or assuming the paint over them is in the painting bid when the spec puts it in yours.
Measuring building insulation areas without separating assemblies with different R-values or products.
Waiting for the mechanical takeoff to finish and re-measuring everything instead of importing the pipe and duct quantities.

Trades that bid the same job

A insulation bid rarely stands alone. The trades next to it on the schedule read the same drawings and often share scope lines, so it pays to know how they take off too: HVAC estimating software, sheet metal estimating software and drywall takeoff software.

Where AmpCount fits

AmpCount only counts electrical devices and fixtures, so it does not measure pipe, duct or building insulation. The only overlap is on the same commercial job, when your company or a partner also bids the electrical scope: AmpCount counts the devices on the electrical sheets while the insulation quantities stay in your insulation or takeoff tool.

How electrical takeoff software counts a plan set

Questions

What is the best insulation estimating software?

For mechanical insulation, a dedicated tool such as FastWRAP that knows pipe sizes, fittings, thickness tables and jacketing¹. For building insulation from plans, a general takeoff tool with area assemblies, such as PlanSwift or STACK.

How much does insulation estimating software cost?

FastEST lists FastWRAP at $4,995 one time for a first application or $250 a month on a lease². PlanSwift starts at $2,000 a year⁴, STACK Premium at $299 per user per month billed annually, and STACK also has a free plan limited to one active project a month⁵.

How do you calculate board feet for spray foam?

Multiply the area in square feet by the thickness in inches. 1,000 square feet at 3 inches is 3,000 board feet, before waste.

How are pipe fittings handled in an insulation estimate?

Either counted as separate items with their own labor, or converted to an equivalent length of straight pipe. Use whichever method matches how your labor data was collected.
