EN ISO 10077-2 Preparation

EN ISO 10077-2, such as the ≤ 2mm cavities, the slightly ventilated cavities or even the corners with increased heat transfer resistance are automatically implemented by the software.



What is changed by introducing the ISO 10077-2:2017?

By introducing the new ISO 10077-2:2017 one of the things which has changed most is the process of calculation heat flow in cavities of Window and facade profile. As an alternative to the simplified model of equivalent heat conductivity the new standard defined a new model which is using detailed heat radiation. This heat radiation model is named „Radiosity”.

EN ISO 10077-2 preparation with cavity model

WINISO® analyses and edits the drawing not just automatically related to the valid standard DIN EN ISO 10077-2:2012, also the detailed radiation model „Radiosity” by the new ISO 10077-2:2017 is included. So you are able to calculate parameters like the Uf by using the old standard of 2012 as well as the standard of 2017.

Powerful calculating engine with a high level of automation

The powerfull FEM-calculating engine is able to give precise calculation of complex components. The networking of finite Elements is made completely fully automatically with the possibility of manual settings and optimizations. Radi and angels are not turned into horizontal and vertical lines as usually done. Instead of doing this with the FEM-mesh the details could be very exactly reproduced to the drawing. Short time of calculation and a high level of exactness are the result of this innovative calculating engine.

High level of automation

The calculation of the FEM-mesh is not the only thing which is done completely automatically by WINISO®. Including a large number of algorithm and functional processes the software is one of the most effective tools to calculate thermal and construction values. While calculating the editor is always able to choose between different accurate settings.

Also an automatically CAD preparation is included in the new WINISO®. Errors which are attached to the drawing will be automatically detected and solved by using different functions. Caused by combination of automatically preparation and using different functions a manually preparation of the CAD drawing is not necessary.

Furthermore it is also possible to choose manual editing options for an individual adjustment. The intuitive interface of the program help the user to save a lot of time by using these options.

Another important new Option is the automatic detection of material. If the name of the layer structure which is used in the CAD drawing is the same as used in the extensive material data base of WINISO® the areas could be filled automatically with right material. It is also easy to bring some special materials to the data base just by giving some less parameters to the program.


WINISO® offers extensive CAD-functions, for an easy and fast editing of CAD-files. The operation to this is very simular to the widely used CAD-programs. To the newest Version of WINISO® a CAD-Editor is connected.

With the Editor the user is able to handle drawings with different tolls very easily in the usual file formats .dwg and .dxf. After changing the drawing it is possible to save it again as a CAD-file.



The handling for the changing is similar to the common CAD-software. It is also possible to import three-dimensional components into the new WINISO®. Furthermore the software is able to generate 3D-componentes into two dimensional pieces. In the next step calculation could start.
