FROM THE THERMAL ENVELOPE TO A PRICED INSULATION ESTIMATE

From Plan Geometry to a Priced Insulation Estimate

Vega extracts the building envelope from floor plans, reads insulation requirements from wall sections and notes, calculates surface quantities, seeds R-value targets, and builds editable material and labor estimates.

STEP 01

Upload the plans

Start with the floor plans, foundation plan, and any reflected ceiling plans. Vega extracts rooms, exterior and interior walls, doors, windows, and the foundation boundary — the geometry behind every insulation quantity.

STEP 02

Read the thermal spec

Vega reads wall sections, insulation schedules, energy-code sheets, and general notes to find R-values, climate zone, conditioned-attic callouts, vapor barrier, baffles, and attic access — the spec the geometry alone cannot show.

STEP 03

Measure the envelope

Each surface is measured or calculated from the shared building envelope: exterior walls net of openings, the top-storey attic footprint, pitch-adjusted vaulted ceilings, rim joists, and the crawl or basement boundary.

STEP 04

Set the R targets

Plan-stated R-values take priority. Where the plans are silent, DOE climate-zone recommendations seed editable defaults for the attic, walls, floor, and crawlspace walls — four independent targets, each driving its own line.

STEP 05

Build the estimate

Vega prices each surface at its own R-value — batt, blown, or spray foam — splits material and labor, applies regional and union adjustments, and carries the reviewed quantities into a client proposal.

Geometry comes from the shared building envelope. Insulation requirements are AI-assisted from plan notes and schedules — the estimator reviews and edits everything in the breakdown.

THERMAL-ENVELOPE TAKEOFF

Every Insulated Surface, Measured or Calculated

Insulation goes on the building thermal envelope — not interior partitions. Vega measures or calculates each surface from the shared building geometry: exterior walls net of openings, the top-storey attic, pitch-adjusted vaulted ceilings, rim joists, and the crawl or basement boundary.

Exterior walls (measured, net of openings)
Exterior wall SF measured from the canvas, or perimeter × height × stories
Window and exterior door openings deducted — a window has no cavity to fill
Net wall SF = gross wall SF − opening SF (§Core Math)
Attic (calculated, top-storey plate)
Flat attic = top-storey footprint, not the sum of every floor area
Vaulted rooms subtracted — their rafter plane is insulated instead
One attic per building, no matter how many storeys
Vaulted & cathedral ceilings (pitch-adjusted)
Sloped ceiling area follows the rafter plane (the hypotenuse over the footprint)
Pitch multiplier shared with Roofing — the two trades never disagree about the same roof
Cavity depth (rafter bay minus vent gap) bounds the achievable batt R
Crawlspace & basement boundary
Vented crawl: insulate the floor above (crawl ceiling)
Encapsulated crawl: insulate the perimeter walls instead
Either/or — one thermal boundary, never both
Rim & band joists
Rim joist SF = perimeter × joist depth × stories
Priced as its own line, matching how real insulation bids itemize it
Batt at the wall R target
Thermal spec (AI-assisted)
R-values read from wall sections, schedules, notes, and energy-code sheets
Climate zone, conditioned attic, vapor barrier, baffles, and attic access
Plan-stated values take priority over climate-zone defaults

Interior partitions carry no insulation unless the sound-batt scope is on. Every quantity is editable in the breakdown.

CLIMATE-ZONE-AWARE ESTIMATING

R-Value Defaults That Follow the Climate Zone

Vega uses DOE-recommended R-values by IECC climate zone to seed editable defaults for the attic, walls, floor, and crawlspace walls. Plan-stated requirements take priority; climate-zone-aware defaults help fill the gaps.

Plan-stated R takes priority

When the plans state an R-value on a wall section, schedule, or energy-code sheet, that fact about this building outranks the climate-zone default. Vega reads it and uses it.

Recommendations, not code compliance

These are DOE recommendations, not a code calculation for any jurisdiction. Vega does not verify IECC compliance, generate ResCheck or COMcheck, or check local energy-code requirements. Confirm R-values against your local code.

ESTIMATE BY R-VALUE, NOT JUST SQUARE FOOTAGE

R-Value Drives Price — and the Cavity Bounds R

Insulation estimating is not square feet × one unit price. Every line states its R, the installed rate is a function of R, and the wall cavity physically bounds what a batt can achieve. Vega prices what fits and warns rather than billing an R the wall cannot hold.

2x4 wall

R-15

3.5″ · Standard or high-density batt

2x6 wall

R-21

5.5″ · R-21 requires high-density batt

Rafter bay

R-30

~9.75″ usable · 11.25″ bay minus 1.5″ vent gap

Open attic floor

R-60+

Unlimited · Free depth — blow to any R

THE PRICING FORMULA

installed $/SF = base + per_r × R

Changing an attic from R-38 to R-60 moves the price — because more glass goes into it. A flat $/SF would make every R dial cosmetic.

When the cavity cannot hold the target R, Vega prices the largest real batt that fits and warns — rather than silently billing an impossible spec.

R targets are editable per surface: attic, wall, floor, and crawlspace wall are four independent values. Common targets include R-13, R-15, R-19, R-21, R-30, R-38, R-49, and R-60.

NET WALL INSULATION AREA FROM THE ACTUAL BUILDING ENVELOPE

Wall Insulation, Net of Openings

Vega calculates exterior wall insulation area from the building envelope and deducts window and exterior door openings — a window has no cavity to fill. The wall height, stud size, and opening deductions are all editable.

What Vega measures

Exterior wall SF from the canvas or perimeter × height × stories
Window and exterior door openings deducted
Net wall SF = gross − openings
Stud size inherited from Framing (2x4 or 2x6)
Wall height editable per estimate

What the estimator controls

Wall material: batt, blown, or spray foam
R target for the wall (drives the rate)
Stud size (caps the achievable batt R)
Gross wall SF and opening deductions
Every rate and labor share
FLAT ATTIC, VAULTED CEILING OR CONDITIONED ROOF DECK

One Attic Strategy Does Not Fit Every Building

Vega distinguishes between a vented attic (blow the floor), a conditioned attic (foam the roof deck), and a hybrid (both on different parts of the house) — rather than applying one flat area everywhere.

Vented attic

Blow the attic floor. Area = top-storey plate. Blown insulation at R-driven depth.

Flat attic floor
Blown cellulose or fiberglass
Depth = R ÷ R-per-inch
Baffles at every rafter bay

Conditioned attic

Foam the roof deck. Area = plate × pitch multiplier (bigger). Closed-cell spray foam at a thickness dial.

Roof deck surface
Closed-cell spray foam
Thickness drives the R
Brings ductwork inside the envelope

Hybrid

Both, on different parts of the house. The two never overlap — the plate is split, never doubled.

Some blown attic floor
Some foamed roof deck
Editable conditioned share
Never the same square foot twice

Vaulted and cathedral ceilings are pitch-adjusted (the hypotenuse over the footprint). The rafter bay depth minus the vent gap bounds the achievable batt R.

CRAWLSPACE, FOUNDATION & RIM JOIST INSULATION

One Thermal Boundary Below Grade

For a vented crawlspace, Vega insulates the floor above. For an encapsulated crawlspace, Vega insulates the perimeter walls instead. The thermal boundary is one surface — either the floor or the wall, never both.

Vented crawl — insulate the floor above

The crawl is outside the envelope. Insulate the crawl ceiling (the floor above) at the floor R target. The ground poly is laid either way — it is a vapor barrier, not insulation.

Encapsulated crawl — insulate the walls

The crawl is inside the envelope. Insulate the perimeter walls at the crawlspace-wall R target. The crawl method is an editable dial in the breakdown.

Basement walls and rim or band joists are priced as their own lines. Vega does not estimate under-slab insulation, slab-edge insulation, or floors over garages.

BATT, BLOWN & SPRAY FOAM MATERIALS

One Workflow, Multiple Insulation Materials

The same surface-based workflow supports fiberglass batt, high-density batt, blown cellulose and fiberglass, open-cell and closed-cell spray foam, optional sound batts, and limited foundation rigid board.

Batt insulation

Fiberglass batt in a product ladder — R-13/R-15 in a 2x4, R-19/R-21 high-density in a 2x6. High-density auto-selected when the R target requires it.

Standard fiberglass batt
High-density batt (R-15, R-21)
2x4 and 2x6 cavity ladders
Sound batts (R-19 unfaced, opt-in)

Blown insulation

Blown cellulose and blown fiberglass for attic floors and loose-fill ceilings. Depth calculated from the R target — free-depth surfaces carry the highest R in the house.

Blown cellulose (R-3.5/inch)
Blown fiberglass (R-2.45/inch)
Attic floor / loose-fill ceiling
Depth = target R ÷ R-per-inch

Spray foam

Open-cell and closed-cell spray foam. Closed-cell at the roof deck (conditioned attic) or in wall cavities. Thickness drives the R; R-per-inch is material-specific.

Open-cell (R-3.5/inch)
Closed-cell (R-6.5/inch)
Roof deck thickness dial
Wall cavity foam

Foundation rigid board

Limited XPS rigid board for foundation walls — 4″ Type IV XPS R-10, continuous. User-entered area; not a broad rigid-insulation estimator.

4″ Type IV XPS (R-10)
Foundation walls only
User-entered area
Continuous insulation below grade

Vega prices insulation by the square foot of each surface at an R-driven rate. It does not calculate purchase quantities such as batt packages, bags, board-feet, or kits.

VAPOR BARRIER & AIR-SEALING SCOPE

Vapor Barrier, Baffles, and the Seal Package

Vega prices the vapor barrier, attic baffles, and the seal package at openings and penetrations. Whole-house air sealing is a separate retrofit scope, off by default. Housewrap and the weather-resistive barrier belong to the Exteriors trade.

Vapor barrier / poly sheeting

Poly sheeting at walls and crawl ground cover. An editable assumption — both real bids carry it, neither prices it separately.

Seal package at openings

Foam at doors, windows, and penetrations. Priced per opening — small, bounded, and on by default. Not a whole-house air-sealing scope.

Whole-house air sealing (opt-in)

A retrofit scope priced per square foot of floor area. Off by default — only turn it on if a whole-house air-sealing scope is genuinely in your bid.

AI ASSISTS. THE ESTIMATOR CONTROLS THE ASSEMBLY.

Review Insulation Takeoffs with a Visual Plan and Editable Breakdown

An insulation estimate is only as good as the R-values and surface assignments behind it. Vega shows the building envelope on the canvas, and every insulation decision — material, R-value, climate zone, attic strategy, crawl method, rates, and labor — is editable in the breakdown.

See the building envelope on the plan

Walls, rooms, doors, windows, and the foundation boundary are visible on the canvas — the geometry behind every insulation quantity.

Set R targets per surface

Attic, wall, floor, and crawlspace-wall R are four independent editable values. Plan-stated values take priority; climate-zone defaults fill the gaps.

Choose the attic strategy

Vented, conditioned, or hybrid. The deck-foam thickness and the hybrid conditioned share are both editable dials.

Set the crawl method

Vented crawl (insulate the floor above) or encapsulated crawl (insulate the perimeter walls). One thermal boundary, never both.

Assign material per surface

Batt, blown fiberglass, blown cellulose, open-cell foam, or closed-cell foam for walls. Material selection drives the R-per-inch and the rate.

MATERIAL + LABOR ESTIMATING

Turn Reviewed Quantities Into Material and Labor Estimates

Vega carries reviewed insulation quantities into a priced material and labor estimate — each surface split into material and labor, with regional, union, and access adjustments. Every rate and assumption is editable.

Priced by surface

Installed $/SF split into material + labor
R-driven rate (base + per_r × R)
Per-surface: wall, attic, deck, slope, rim, crawl
Vapor barrier, baffles, and seal package
Optional sound batts and retrofit scopes

Labor adjustments

Regional labor index (labor only)
Union / non-union multiplier
Difficult-access premium (on labor)
Every labor share editable
Cost Library defaults with user overrides

Regional adjustment affects installation labor only — batt and blown insulation material is a nationally-traded commodity. Vega does not provide live, real-time, or ZIP-code pricing.

TRADE BOUNDARIES

Insulation Scope, Kept Where It Belongs

Vega trade workflows help separate overlapping construction scope — so insulation, framing, drywall, exteriors, roofing, waterproofing, fireproofing, and ceiling systems each own their part of the building.

Insulation

Thermal cavity insulation
Attic & roof-deck foam
Crawl & rim insulation
Sound batts (opt-in)
Vapor barrier & seal package

Framing

Wood & steel studs
Blocking & sheathing
Structural framing
Cavity geometry

Drywall

Gypsum board
Tape & mud
Level 0–5 finish
QuietRock & resilient channel

Exteriors

Siding & cladding
WRB & housewrap
Exterior finishes
EIFS

Roofing

Roof covering
Membranes

Flashing

Waterproofing

Below-grade membranes

FAQ

Frequently Asked Questions

What is insulation estimating software?

Insulation estimating software helps contractors turn construction plans into insulation quantities — wall, attic, ceiling, roof-deck, crawlspace, and rim-joist surface areas at their own R-values — and then into material and labor pricing and a reviewable estimate. Vega is built around that workflow for insulation subcontractors, general contractors, and estimators.

Can Vega create insulation takeoffs from PDF plans?

Yes. Vega extracts the building envelope — walls, rooms, doors, windows, and the foundation boundary — from floor plan PDFs, reads insulation requirements from wall sections, schedules, and notes, and builds an editable insulation estimate. This is an AI-assisted, estimator-controlled workflow — not a one-click automatic takeoff. You review and edit the geometry and the insulation decisions before pricing.

Does Vega calculate wall insulation area?

Yes. Vega measures exterior wall area from the building envelope and deducts window and exterior door openings — a window has no cavity to fill. Net wall area = gross wall area minus opening area. The wall height, stud size, and opening deductions are all editable in the breakdown.

Does Vega estimate attic insulation?

Yes. Vega calculates the attic floor as the top-storey footprint — not the sum of every floor area, which would bill a two-storey house for two attics. Vaulted rooms are subtracted because their rafter plane is insulated separately. The attic can be vented (blow the floor), conditioned (foam the roof deck), or hybrid (both on different parts of the house).

Can Vega estimate vaulted ceiling insulation?

Yes. Vega detects vaulted and cathedral ceilings from room geometry and calculates their area with a pitch multiplier — a sloped ceiling is the hypotenuse over its footprint, bigger than the flat floor below it. The rafter bay depth (minus the vent gap) bounds the achievable batt R, and Vega prices the largest real batt that fits rather than billing an R the cavity cannot hold.

Does Vega support spray foam?

Yes. Vega supports open-cell and closed-cell spray foam with R-per-inch logic and a thickness dial. Closed-cell foam at the roof deck is the conditioned-attic strategy; foam in wall cavities is an alternative to batt. Vega prices spray foam by the square foot of surface at an R-driven rate. It does not calculate board-feet, gallons, kits, drums, or yield — it is an estimating tool, not a spray-foam purchase calculator.

Does Vega support blown insulation?

Yes. Vega supports blown cellulose and blown fiberglass for attic floors and loose-fill ceilings. The depth is calculated from the R target (depth = R ÷ R-per-inch), which is why an open attic floor can carry the highest R in the house. Vega does not calculate bag counts, coverage per bag, or settled-depth adjustments — it estimates surface quantities and prices them.

Does Vega use R-values in the estimate?

Yes — R-value is the top-level dial. Every insulation line states its R, and the installed rate is a function of R (rate = base + per-R × R), not a flat square-foot price. Changing an R target moves the price. Wall cavity depth constrains the achievable batt R, and Vega prices what fits and warns rather than billing an R the wall cannot hold.

How does Vega use climate zones?

Vega uses DOE-recommended R-values by IECC climate zone to seed editable defaults for the attic, walls, floor, and crawlspace walls. It can read a plan-stated climate zone, fall back to the project state, or accept a manual entry. Plan-stated R-values and user edits always take priority over the climate-zone defaults. These are recommendations, not code compliance — Vega does not verify IECC compliance, generate ResCheck or COMcheck, or check jurisdictional energy-code requirements.

Does Vega verify insulation code compliance?

No. The climate-zone-derived R targets are DOE recommendations, not a code calculation for any jurisdiction. Vega does not generate ResCheck, COMcheck, or Title 24 documentation, and it does not verify compliance with any energy code. Confirm R-value requirements against the DOE climate zone map and your local energy code.

Can I edit insulation quantities and R-values?

Yes. Every quantity, R target, material, rate, labor share, scope, and assumption is editable in the breakdown. You can override wall area, opening deductions, attic strategy, crawl method, stud size, climate zone, the regional labor index, the union bump, and the difficult-access premium. You can add custom items and include or exclude any line. Reset to defaults anytime.

Does Vega calculate insulation bags or batt packages?

No. Vega calculates insulation surface quantities — square feet of wall, attic, ceiling, roof deck, crawlspace, and rim joist at their own R-values. It does not convert to purchase quantities such as batt packages, rolls, bags, rigid-board sheets, spray-foam board-feet, or kits. The estimate is priced by the square foot of each insulated surface.

Does Vega estimate insulation labor?

Yes. Vega splits each installed rate into a material line and a labor line, applies a regional labor index (labor only — batt and blown material is a nationally-traded commodity), a union or non-union multiplier, and an optional difficult-access premium to labor. Every labor share, rate, and adjustment is editable.

Can Vega estimate crawlspace insulation?

Yes. For a vented crawlspace, Vega insulates the floor above (the crawl ceiling). For an encapsulated crawlspace, Vega insulates the perimeter walls instead. The thermal boundary is one surface — either the floor or the wall, never both — and the crawl method is an editable dial. Basement walls and rim joists are priced as their own lines.
