InsulR Calc
iOS Universel / Utilitaires
InsulR Calc is a fast, offline insulation R-value and thickness calculator for contractors, builders, and energy auditors. Look up R-values or find required insulation thickness for any common material.
WHAT IT CALCULATES:
R-Value from Thickness:
- Select an insulation material from the built-in list
- Enter the installed thickness in inches
- Get the total R-value and U-factor instantly
Required Thickness:
- Choose your insulation material
- Enter your target R-value
- See the exact thickness needed to meet that R-value
MATERIALS INCLUDED:
- Fiberglass Batt (R-3.2/in)
- Fiberglass Blown (R-2.5/in)
- Cellulose Blown (R-3.5/in)
- Mineral Wool (R-3.3/in)
- XPS Foam Board (R-5.0/in)
- EPS Foam Board (R-3.8/in)
- Polyisocyanurate (R-6.0/in)
- Spray Foam Open Cell (R-3.6/in)
- Spray Foam Closed Cell (R-6.5/in)
IECC CLIMATE ZONE REFERENCE:
- Built-in IECC climate zone lookup (Zones 1 through 7-8)
- See minimum R-value requirements for walls, ceilings, and floors
- Quickly check if your insulation meets code for your zone
KEY FEATURES:
- Two-way calculator: R-value from thickness or thickness from R-value
- U-factor output for energy calculations
- 9 common insulation materials with accurate R-per-inch values
- IECC climate zone minimum requirements built in
- Works completely offline
- No account or login required
BUILT FOR THE JOB SITE:
Whether you are an insulation contractor, general contractor, home inspector, or energy auditor, InsulR Calc gives you quick R-value lookups and thickness calculations. Enter your material and thickness to get R-value, or enter your target R-value to find required thickness in seconds.
Supports all common residential and commercial insulation materials per IECC and ASHRAE standards.
