With the U-value and Psi-value Wizard, you can calculate these parameters automatically with a few clicks.

Equivalent U-Value

The equivalent U-value takes into account the effect of periodic thermal bridges.

With the first two clicks you set the cross section line, thus defining the surface edge over which the equivalent U-value is to be calculated. After, you define with a third click the position of the measurement lines.

Frame U-Value

You can determine the U-value for a window frame automatically for constructions which fulfill all conditions of the standard ISO EN 10077-2.

Show

Joint U-Value

Joint U-Values according to EN 13947 are calculated for mullion and transom constructions.

In contrast to the frame U-value according to EN ISO 10077-2 the joint U-value already contains the thermal influence of the spacer or edge.

Psi-Value 2 Constructions

The Psi-value takes into account the additional heat loss caused by a thermal bridge. flixo professional requires just three mouse clicks for calculating the Psi-value. The first two points define the surface line, through which the effective heat flux should be calculated (reference set of energy). You then have to define a third reference point, which divide the surface line in two...

The Psi-value takes into account the additional heat loss caused by a thermal bridge.

flixo professional requires just three mouse clicks for calculating the Psi-value. The first two points define the surface line, through which the effective heat flux should be calculated (reference set of energy). You then have to define a third reference point, which divide the surface line in two parts with different U-values.

Psi-Value 3 Constructions

With this flixo professional Wizard you can calculate Psi-values of constructions, which have 3 connected constructions. The 2 thermal junctions are either identical (both Psi-values are equal) or one connection is "free of thermal bridges" (one Psi-value of one connection is zero). Typical applications are spacer Psi-values for mullion constructions or the Psi-value of a window-wall...

With this flixo professional Wizard you can calculate Psi-values of constructions, which have 3 connected constructions. The 2 thermal junctions are either identical (both Psi-values are equal) or one connection is "free of thermal bridges" (one Psi-value of one connection is zero).

Typical applications are spacer Psi-values for mullion constructions or the Psi-value of a window-wall junction, if the glazing of the window is replaced by a panel according to EN ISO 10077-22.

To calculate and display the Psi-value four points are required: the first two points define the surface line, through which the effective heat flux should be calculated. The third and the fourth point (reference points) divide the surface line in 3 domains with different U-values.

Edge Psi-Values

Edge Psi-Values according to EN ISO 10077-2 are calculated for the thermal evaluation of spacers and glazing edges. With the flixo-Wizard the calculation of an edge Psi-value happens in only two steps: First select the result object for which you want to calculate the edge Psi-value, second select the file with the frame U-value calculation.
