Vitrages Décision, VD, is an essential tool developed by Ginger CEBTP to carry out thermal calculations on insulating glazings as well as to check mechanical constraints.

It is intended for all those involved in the construction industry to approve, size and check glazing behaviour in climatic conditions.

It is continuously updated to comply with any changes in standards and regulations. Databases of the components used such as glazings, blinds, films and inserts are updated as and when they change

NF EN 410 and NF EN 673 calculation methods are certified by TÜV Rheinland (report n° 89206581)
