1. INTRODUCTION
The Reynaers U-tool software calculates the U-values of windows, doors, sliding doors and
curtain walls. In this tool one has a selection of various Reynaers systems, profile combination and
model configurations. By selecting the correct one and adjusting parameters to meet those of the
project, one can get the Uw (window), Ud (door) or Ucw (curtain wall).
All calculations are done according to the following standards:
EN ISO 10077-1:2006 and EN ISO 10077-2:2012 for windows, doors and sliding doors
EN ISO 12631:2012 for curtain walls (component and single assessment method)
1.1 Possibilities
The U-tool is a web-based software for easy calculation of U-values. It is available in Dutch,
English and French. It is possible for users to manage their own projects and safely store them online.
Each project can contain different configurations giving the user more flexibility. An overall U-value
can also be calculated for all project configurations. A report can be created just by one click. The
configurations that will appear in the report can be selected.
1.2 Where to find it
On Reynaers extranet, at TOOLS you will find U-tool. By clicking on it, you will be redirected
to the Reynaers U-tool page.

this tab you can also define the dimensions of the element and the glass thickness. The steps that
need to be followed are:
Step 1
Choose a profile system.
Step 2
Fill in a name for the model.
Step 3
Fill in the number of elements in the project.
Step 4
Fill in total width of element.

data concerning the selected profile appears.
User manual of 17/06/2016 pag. 12/40
3.1.4 Glass tab
In the glass tab, the glass parameters can be changed. The user can change the parameters of
all glass in the model by using the default values, or change each glass individually by clicking on the
glass and changing the parameters in the selected glass field.
Changing glass parameters – Default values
Step 1
Select the glass composition.
Step 2
Fill in the Ug value of the glass.

User manual of 17/06/2016 pag. 14/40
Changing glass parameters – Thermally improved spacers
Another parameters that can be changed in the Glass tab is the glass spacer type. There is a
selection to choose from an aluminium spacer, to various specific thermally improved ones. When
selecting the aluminium spacer, or the thermally approved spacer, the ψ-values that are used are
those according to EN 10077-1 and no further information is required. However, when a thermally
improved spacer is selected, the glass composition needs to be filled in.*
* Depending on the glass composition used, the ψ-value of the thermally improved spacers needs to be corrected, according to the ift guidline WA-08/3. When entering the desired glass composition, these corrections are done automatically. The corrected ψ-value is then used in the calculation.

User manual of 17/06/2016 pag. 25/40
3.4 Curtain wall – SC and SG
3.4.1 Choosing a model
There are also SC or SG systems in the curtain wall models that have Utj-values** instead of
Uf-values. These systems can be found in the dropdown list of the curtain wall systems. The starting
procedure is exactly the same as in 3.3.
Step 1 First fill in the grid size and then click on continue. The maximum size for the grid is 5x5.
3.4.2 Model tab
When selecting one of the SG or SC systems, you get the below screen. In this tab you can fill
in the width and height of the element.
** Utj-values represent the heat flow through the filling element (glazing/panel), the thermal joint (frame) and the edge effect due to the interaction between the filling element and the thermal joint. This means
that the ψ-value has been taken into account in the thermal transmittance calculations
User manual of 17/06/2016 pag. 26/40
3.4.3 Profile tab
In this tab you can select the mullion and transom profiles. You can also see the details about
the profile that is selected in the image.
3.4.4 Glass tab
The glass tab is different in the SG and SC systems. Here you must select a specific type of
glass, a specific glass composition and Ug value and the type of spacer.
User manual of 17/06/2016 pag. 27/40
Restriction of curtain wall model:
1. Transoms are always in line for one configuration
A solution to this restriction is to separate them into multiple configuration, like in the image below.
2. In the SC and SG curtain wall systems, only fixed glazing elements can be calculated. Opening
parts cannot be inserted to the model.

3.5 Door element
3.5.1 Choosing a model
Step 1
Choose a door model.
User manual of 17/06/2016 pag. 29/40
3.5.2 Model tab

tab you can also define the dimensions of the element and the glass thickness. The steps that need
to be followed are:
Step 1
Choose a profile system.
Step 2
Fill in a name for the model.
Step 3
Fill in the number of elements in the project.
Step 4

User manual of 17/06/2016 pag. 30/40
3.5.3 Door tab
In the door tab, the door type and the door opening type can be selected.
When selecting a profile system in the Model tab, some systems (e.g. Masterline 8) give an error (below
image). This happens because the default door type is a flat door and the default door opening type is
inward opening. However, in some systems only window doors are available, so when selecting those
systems before selecting a door type, you will get an error. If this error occurs, go first to the Door tab and
select the correct window door type or opening type and then go back to the Model tab and select the
system.
User manual of 17/06/2016 pag. 31/40
3.5.4 Profile tab
In the profile tab, the lengths of individual profiles can be changed by clicking on each profile
in the image.

data concerning the selected profile appears.
User manual of 17/06/2016 pag. 32/40
3.5.5 Bottom solution
In the Bottom solution tab, the bottom solution used can be selected. By clicking on the bottom
profile in the model, you get redirected to the Bottom solution tab and the various available bottom
solutions are shown. There are images so that the correct one can be selected.
By clicking on the image of the bottom solution, it gets selected and those parameters are
used in the calculation. The length of the bottom profile can also be changed here. The other profiles
lengths get adjusted automatically.
User manual of 17/06/2016 pag. 33/40
3.5.6 Glass tab
The procedure to set the glass parameters is the same as in the previous examples. The user
can change the parameters of all glass in the model by using the default values, or change each glass
individually by changing parameters by clicking on the glass.
User manual of 17/06/2016 pag. 34/40
3.5.7 Panel tab
Like in the case of a window calculation, a panel can be selected for one or all of the door panes.
The same procedure as in the windows needs to be followed.
Step 1
Select the glass you want to change.
Step 2
Change type to panel.
Step 3
Go to panel tab.
Step 4
Fill in default panel values or change the properties of the selected panel.
User manual of 17/06/2016 pag. 35/40
3.6 CS 77-Panel door / CS 86-HI-Panel door / CS86-HI+-Panel door
This chapter covers the procedure that should be followed when calculating the Ud values of the
Reynaers CS 77-Panel Door, CS 86-HI-Panel Door and CS 86-HI+-Panel Door systems.
The profiles of systems CS 77-Panel Door, CS 86-HI-Panel Door and CS 86-HI+-Panel Door can
be found in Chapter 3.6.3.
All steps are as in chapter 3.5. However, the CS 77-Panel door, CS 86-HI-Panel door and CS 86-
HI+-Panel door systems are only available for door model 301, so when selecting any other model,
these systems will not be present in the dropdown list. In the door tab, some specific steps need to be
followed. In chapter 3.6.2 these steps can be seen.
3.6.1 Choosing a model
Step 1
Select door model 301.
User manual of 17/06/2016 pag. 36/40
3.6.2 Door tab
In this tab you can select a panel. You can also select the door type and the door opening type.
Step 1
Click on the area of the glazing/panel and select ‘Panel’ from the dropdown list.
Step 2
Select door type and door opening type.
User manual of 17/06/2016 pag. 37/40
Step 3
Fill in the Up-value of the panel.
Step 4
Select ‘Free entry’ as a spacer type and leave the ψ value 0.00 W/mK. ***
***
a. If leaving spacer as ‘None’ the ψ-value of an aluminium spacer is used and a wrong Ud will be
calculated.
b. In the case of the CS 77-Panel Door, CS 86-HI-Panel Door and CS 86-HI+-Panel Door systems
the U-tool takes into account a Utj-value and not a U
f-value. The U
tj-value represents the heat
flow through the filling element (panel), the thermal joint (frame) and the edge effect due to
the interaction between the filling element and the thermal joint. This means that the ψ-value
has been taken into account in the thermal transmittance calculations. Thus, when calculating
the thermal transmittance of a door that consists of these profiles, a ψ-value equal to 0.00
W/mK must be taken.
