Kingspan U-Value Calculator UK
Understanding the U-value of your Kingspan insulation is crucial for energy-efficient building design. Our calculator helps you determine the U-value of your Kingspan insulation, ensuring your building meets UK building regulations.
- Select the thickness of your Kingspan insulation.
- Choose the insulation type.
- Click ‘Calculate’.
The U-value is calculated using the formula: U = 1 / (R + Rf + Rs), where R is the thermal resistance of the insulation, Rf is the thermal resistance of the facing, and Rs is the thermal resistance of the stud.
| Thickness (mm) | Insulation Type | U-Value (W/m²K) |
|---|---|---|
| 50 | PUR | 0.022 |
| 75 | PIR | 0.015 |
| 100 | EPS | 0.010 |
| Insulation Type | Thermal Conductivity (W/mK) |
|---|---|
| PUR | 0.024 |
| PIR | 0.022 |
| EPS | 0.035 |
- Always use the correct U-value in your calculations to ensure compliance with building regulations.
- Consider using higher density insulation for better thermal performance.
What is the U-value?
The U-value, or thermal transmittance, is a measure of how well a building element prevents heat transfer. It’s expressed in W/m²K.
How does the calculator work?
The calculator uses the thermal conductivity of the insulation and the facing, along with the thickness of the insulation, to calculate the U-value.
