Software Calculator U-Value Thermal Bridging

Introduction & Importance

Software calculator u-value thermal bridging is a critical tool for architects and engineers to assess the thermal performance of building envelopes…

How to Use This Calculator

1. Enter the U-Value of the building envelope.
2. Enter the bridging factor, typically provided by the manufacturer.
3. Click ‘Calculate’ to see the results and chart.

Formula & Methodology

The calculator uses the following formula to calculate the effective U-value with thermal bridging:

U_eff = U + (f * U * Δt)

Real-World Examples

Data & Statistics

Comparison of U-Values with and without Thermal Bridging

Building Envelope	U-Value (W/m²K)	Bridging Factor	Ueff (W/m²K)
Concrete Wall	0.5	0.2	0.6

Expert Tips

• Always use manufacturer-provided bridging factors for the most accurate results.
• Consider using higher performance materials to reduce thermal bridging.
