Insulation Calculator
Calculate insulation requirements for walls, roofs, and floors. Determine thickness needed to achieve target R-value or U-value.
R-value: 0.025 m²K/W per mm | Density: 40 kg/m³
Enter insulation requirements to calculate materials
ESTIMATION NOTICE
This calculator provides APPROXIMATE QUANTITIES for budgeting and planning purposes.
Please note:
• Results include standard wastage factors but actual waste may vary based on site conditions, workmanship, and material quality.
About This Calculator
The Insulation Calculator helps MEP engineers and contractors determine thermal insulation requirements for buildings across the UAE and Gulf region. Calculate insulation thickness needed to achieve target R-values or U-values for walls, roofs, and floors. Essential for meeting Estidama Pearl rating requirements, Dubai Green Building regulations, and achieving energy-efficient designs in the extreme Gulf climate.
When to Use This Calculator
- Designing wall assemblies to meet energy code requirements
- Specifying roof insulation for Gulf climate conditions
- Calculating insulation thickness for Estidama compliance
- Comparing insulation material options and costs
- Verifying HVAC load reduction from improved insulation
How to Use This Calculator

Enter Target Performance
Input required R-value (thermal resistance) or U-value (thermal transmittance).
Choose Insulation Material
Select material: XPS, EPS, mineral wool, PIR, or spray foam with its k-value.
Specify Assembly Details
Enter existing construction layers and their thermal properties.
Calculate Results
Get required insulation thickness, material quantity, and cost estimate.
Typical Scenarios in UAE & Gulf Projects
A commercial tower requires wall assembly with U-value of 0.3 W/m²K for Estidama 2 Pearl compliance. The calculator determines 75mm XPS insulation (k=0.034) is needed in the curtain wall cavity to achieve the target, reducing cooling loads by 25% compared to uninsulated assembly.
A residential villa needs roof insulation for ADQCC energy compliance with R-value of 3.5 m²K/W. Calculator specifies 120mm PIR board (k=0.022) above the concrete slab, reducing summer heat gain and achieving significant HVAC energy savings.
