R-38 attic insulation can be achieved with 12 inches of fiberglass batt, 10 inches of blown-in cellulose, or 6 inches of closed-cell spray foam. Each achieves the same thermal performance. Each carries a completely different material cost, installation labor rate, and equipment requirement. Applying a single insulation rate across dissimilar materials produces a number that misrepresents the specified system before a single square foot is installed.
Insulation Estimating Services Covering Every System and Application
Insulation estimates built on surface area and a single R-value miss the most important variables. Material type, climate zone requirements, vapor retarder class, open versus closed cell selection, and pipe insulation thickness all determine your true insulation cost. Our insulation estimating services give contractors specification-accurate numbers across every system and substrate.

What Our Customers Say
Samuel Price
We engaged Federal Estimating for insulation estimating on a large healthcare facility project, and the results were outstanding. Their estimate included detailed quantities for thermal insulation, acoustic insulation, and specialty systems, all clearly categorized by area and specification. The report gave our team the confidence to submit an accurate and competitive proposal. Their technical knowledge and attention to detail were evident throughout the process.
Allison Murphy
Federal Estimating provided insulation takeoffs for our multi-family residential development, and the quality of the deliverables exceeded expectations. The estimate was easy to review and thoroughly covered wall, ceiling, floor, and mechanical insulation requirements. Their precise calculations improved our material planning and reduced the likelihood of costly overruns. The service was timely, professional, and highly reliable.
Derek Lawson
Our insulation contracting company relied on Federal Estimating for a large distribution center project with a tight bid schedule. The estimate accurately quantified batt insulation, rigid board insulation, spray foam, and associated accessories. Their detailed scope review allowed us to identify several items that could have otherwise been overlooked. We were extremely pleased with the quality of work and overall experience.

Frequently Asked Questions
Insulation estimating fees are based on project size, number of insulation systems, material complexity, and required turnaround. Residential insulation estimates for single-family homes covering batt, blown-in, and spray foam scopes typically start at $150 to $350. Commercial insulation packages covering thermal, acoustic, and mechanical pipe insulation systems on mid-sized projects range from $400 to $1,200. Industrial insulation estimates for process piping and equipment are quoted individually after reviewing your mechanical drawings. We provide a fixed price before any work begins.
Open-cell spray foam expands significantly during application, produces a soft, spongy material at approximately R-3.7 per inch, and is vapor permeable, meaning moisture vapor can pass through it. Closed-cell spray foam remains dense and rigid after application, achieves approximately R-6.5 per inch, and acts as a Class II vapor retarder. Closed-cell costs two to three times more per board foot than open-cell. The specification determines which type is required, and the specified type determines both the material cost and the required thickness to achieve the project's target R-value at each location.
The International Energy Conservation Code divides the US into eight climate zones based on heating and cooling degree days. Each zone mandates minimum R-values for wall assemblies, attic insulation, floor insulation, and foundation systems. A building in Climate Zone 7 requires wall cavity insulation and continuous exterior insulation significantly more robust than the same building type in Climate Zone 3. We confirm the applicable climate zone and current IECC code edition for your specific project location before performing any insulation quantity calculations so your estimate reflects enforceable code minimums rather than national averages that may not apply to your jurisdiction.
Yes. Mechanical pipe insulation and building envelope insulation are estimated as completely separate scopes within every comprehensive insulation package we produce. Pipe insulation thickness requirements are governed by ASHRAE 90.1 based on pipe service temperature and nominal diameter, not by building code R-value minimums. Domestic hot water pipe, chilled water pipe, refrigerant suction line, and steam distribution pipe each carry different insulation specifications, thickness requirements, and jacketing systems. We calculate pipe insulation linear footage by service type and diameter, fitting insulation quantities by type, and valve and equipment insulation separately from envelope scope.
Residential insulation estimates for straightforward single-family projects are typically delivered within one to two business days. Commercial insulation packages covering thermal, acoustic, mechanical pipe, and specialty systems across a mid-sized building are generally completed within two to four business days. Industrial insulation estimates for process piping and equipment jacketing are scheduled individually based on system complexity and drawing completeness. Rush delivery is available for projects with imminent bid deadlines. Share your submission date when submitting, and we will confirm our turnaround commitment before you engage us.
