Thermal properties calculations

Building products which subject to calculation):

The main products or building systems calculated for thermal properties:

- Curtain walling, windows & doors
- Shutters
- Structural frame work / finishing work
-...

 

Results of the calculation:

Hydrothermal calculation and analyze of building components in 2D with stationary boundary conditions (temperatures and coefficients of heat transfer) using finished elements (triangular elements).
Presentation of isotherms and temperature fields of the construction details for a qualitative evaluation and thermal optimization.
Determination of the critical surface temperatures critical for evaluation the conditions of dew and mold growth.
Calculation of coefficient of thermal transmittance ("U-value of the profile of a finished product") and coefficient of linear thermal transmittance ("Psi-value") for the quantification of the effect of thermal bridge.
