Insulation Estimating
Thermal, acoustic and sarking quantities measured in m² and by R-value
Insulation looks simple until the energy report asks for different R-values in ceilings, external walls, floors and party walls, and acoustic ratings change the product again.
We measure each location by area and R-value, convert to pack counts where needed, and add sarking, fixings and labour so your tender reflects the real specification.

Australian Framework
How This Work Fits Into the Australian Standards
Every estimate is structured to the trade sections used for tendering and to the elements used for early cost plans, so one set of quantities serves both.

How We Prepare Your Estimate
Five steps from your drawings to a insulation number you can defend in a scope review.
-
01
Scope review
An estimator reads the architectural plans, energy report, specification and any NCC Section J requirements before touching a takeoff tool, and lists every assumption, exclusion and missing item as a query for you to confirm. Nothing is priced on a guess.
-
02
Digital measurement
Quantities are measured digitally in Bluebeam Revu, PlanSwift or On-Screen Takeoff, in metric: square metres of insulation by R-value and location, with pack counts for batts. Each measurement sits on a named layer, so the marked-up PDF you receive is a visual audit trail.
-
03
Pricing
We price the quantities using current Australian supplier quotes, subcontract rates and published benchmarks such as Rawlinsons, adjusted for your postcode and state. If you give us your own rates or a preferred supplier schedule, we use those.
-
04
Senior QA review
Before anything is sent, a second estimator compares the takeoff with the drawings and verifies the measuring rules, deductions, wastage allowances and productivity assumptions.
-
05
Delivery
Excel and PDF files reach your inbox within one to two days for standard jobs. One round of changes is included, and we remain available for tender queries and scope questions after the tender.
Tooling
Software We Work In
You do not have to hold a licence for these tools. We do the measuring with them and hand over the results.
Bluebeam Revu
Measuring, marking and comparing drawings on screen.
PlanSwift
Takeoffs made from ready-built assemblies, with quantities you can export.
On-Screen Takeoff
Layer-based measuring on big commercial drawing sets.
Rawlinsons-benchmarked rates
Up-to-date Australian unit rates, compared with supplier and subcontractor quotes.
Microsoft Excel
The final file, set out to match your cost codes and trade sections.
If you use Buildsoft, CostX, Estimate One, Procore or your own template, let us know and we will prepare the file so it imports straight in.

Cost vs. Capacity
Why Builders Hand Insulation Estimating to Us
A full-time estimator is a salary, super, software seats and training. A insulation takeoff from us is a per-project cost that only appears when you are actually tendering.
- No software licences. Takeoff and cost-data subscriptions cost thousands of dollars per user each year. With us, you use ours.
- Tender more, more selectively. Most builders do not lose jobs through bad pricing. They lose them because they run out of time to reach enough tenders before closing.
- Site time stays site time. Items get overlooked when estimating at 9pm after a long day on site.
- Independent accuracy check. Even builders with in-house estimators use us to sanity-check large or unfamiliar insulation scopes before they submit.
- Moves up and down with how busy you are. Five takeoffs in a busy month and none in a slow one. You never carry a fixed cost.

Sample Output
Sample Line Items
Every estimate has this much detail: quantities tied to elements and measured in metric, never lump sums.
| Item | Unit | Qty | Material | Labour | Total |
|---|---|---|---|---|---|
| Ceiling batts R4.0 | m² | 212.0 | $ | $ | $ |
| Wall batts R2.5 | m² | 318.0 | $ | $ | $ |
| Foil sarking | m² | 240.0 | $ | $ | $ |
| Acoustic batts, party wall | m² | 96.0 | $ | $ | $ |
| Underfloor R2.0 batts | m² | 140.0 | $ | $ | $ |

FAQ
Common Questions
Do you measure to R-values?
Yes. Each location is measured by area and R-value as required by the energy report or specification.
Do you include acoustic insulation?
Yes, by rating and location.
Do you convert to packs?
Yes, pack counts are included for supplier quoting.
Do you price sarking?
Yes, as a separate line.
Which states and territories do you cover?
Every one. Prices are set for your project postcode and state, so a job in Darwin and a job in Melbourne get their own unit costs instead of one national average.
What does it cost?
A fee is quoted per project, in AUD excluding GST, before any work starts. You approve it in writing first. There is no hourly billing and no invoice larger than the quote.
How fast is turnaround?
Standard scopes ship in 24 to 48 hours. Large packages take 48 to 72 hours. If you are against a closing time, say so when you upload and we will tell you honestly whether we can meet it.
Are my project details kept confidential?
Yes. We keep drawings, specifications and tender figures private, and if you prefer we will sign your NDA before we receive any documents.
