U Value Calculator

Correct U-values are increasingly important in construction projects where the insulation value has to meet legal or project requirements. Therefore, we have developed an easy-to-use U-value calculator for flat roof applications.

Calculations are possible in 2 directions:

  • Calculating the U-value of the construction by selecting the construction element types and their thicknesses.
  • Calculating the thickness of the FOAMGLAS for the given U-value by selecting the missing construction element types and thicknesses.

The U-value calculator will give you a first indicative U-value.

Please note that, at a final stage, it is best to contact a Foamglas sales engineer, for a more thorough calculation.
