Isover Insulation U-Value Calculator
U-value, or thermal transmittance, is a crucial factor in building insulation. It measures how well a building element prevents heat transfer. The lower the U-value, the better the insulation. Isover’s insulation products significantly improve U-values, reducing energy loss and lowering heating costs.
- Enter the thickness of the Isover insulation product in millimeters.
- Enter the product’s conductivity value in W/mK.
- Click ‘Calculate’ to find the U-value and see a visual representation.
The U-value is calculated using the formula: U = 1 / (thickness / conductivity). The calculator uses this formula to determine the U-value based on your input.
| Product | Thickness (mm) | Conductivity (W/mK) | U-Value (W/m²K) |
|---|---|---|---|
| Isover Optima | 100 | 0.035 | 28.57 |
| Isover Metac | 50 | 0.038 | 13.16 |
| Isover Vario | 80 | 0.036 | 22.22 |
| Material | Thickness (mm) | Conductivity (W/mK) | U-Value (W/m²K) |
|---|---|---|---|
| Isover Optima | 100 | 0.035 | 28.57 |
| Polyurethane | 100 | 0.022 | 45.45 |
| Mineral Wool | 100 | 0.040 | 25.00 |
- Consider the overall U-value of your building envelope, not just individual elements.
- Use higher density Isover products for better U-values in challenging conditions.
- Regularly inspect and maintain insulation to prevent degradation and maintain U-values.
