Calculate vacuum glass with WINSLT®

Due to its lighter construction and high insulation values, vacuum glass is increasingly used – especially for the renovation of old buildings and in the field of monument protection. The new WINSLT add-on takes this fact into account. It makes it possible for the first time to carry out an exact, fully automatic calculation of vacuum glazing based on existing ISO/FDIS standards.

Validation of the WINSLT® software by ift Rosenheim

The calculation program WINSLT® has been validated by the ift Rosenheim on standard-compliant execution of the calculations of light, solar and thermal properties of glazings according to the standards EN 410 and EN 673.

The validation report for WINSLT® prepared by ift Rosenheim can be viewed here.

If you are not already using WINSLT® successfully or are not yet familiar with the functions of the software, you can watch the following video to remember the most important features of WINSLT®

Tested products available in the new acoustic database

The software products “WINSLT®” and “GLASGLOBAL®” of Sommer Informatik GmbH from Rosenheim were extended by a database for tested superstructures and their accustic insulation dimensions.

WINSLT® is the software solution for calculating light, solar and thermal properties of glazing in combination with sun protection.

GLASGLOBAL® is the software for the calculation of the static proof according to DIN 18008 and the load assumptions according to DIN EN 1991-1. Both products have access to the stored accustic database.

Currently there are already more than 150 products in the accustic database, all of which, including the respective test certificate, can be used for calculations.

Furthermore, you have the possibility to select the products already available in the software and to compare them via the automatic product search with the superstructures available in the accustic database.

You can also store specially generated products in the software as user-defined products and compare them with the existing products in the accustic database.

WINSLT® and GLASGLOBAL® will give you a list of the products from the accustic database that match your structure or have similarities.

Due to the large participation of manufacturers of glazings and sun protection equipment, we provide you with the accustic database, a constantly growing product database for your calculations.

Press release WINSLT® ASHRAE

WINSLT® is the software for calculating light, solar and thermal properties of glazing in combination with sun protection. An assembly can be created and analyzed in a short time. Since the characteristic values of the glazings can already be calculated according to the European standards EN ISO 673, EN 410 and EN ISO 13363-2, it is now also possible to carry out the analysis according to the ISO 15099 standard in North America.

New version: summer thermal insulation according to North American standards

ISO 15099, the North American standard for calculating the thermal performance of windows, doors and sun protection devices, in some cases provides two ways of calculating a characteristic value. Therefore, the professional association of all companies in the heating, cooling, ventilation and air conditioning industry in the USA, also known as ASHRAE, specifies the path to follow. The calculation basis from the standard with the ASHRAE specifications, some of which also include the NFRC standards, is implemented in the software algorithm.

WINSLT® ASHRAE – quick results thanks to intuitive operation

Because the innovations are mainly in the algorithm of the software, the intuitive handling of the WINSLT® Standard and WINSLT® Expert modules is retained. A glass structure can thus be created and subsequently analysed in the shortest possible time. An extensive database with various products from international glass manufacturers is also available for this purpose, which can be extended as required by importing your own spectral data.

Standards-compliant implementation

A visible change is the selection of boundary conditions. The specially defined specifications of ASHRAE are available here. These are also shown on the clear printout, which outputs all characteristic values such as the SHGC value, the equivalent of the European g value.

Investment security for the future

Whether glass manufacturer, planner or expert, with intuitive operation and extensive user support you will receive your analysis of the glass structure in no time at all. From simple insulating glass to complex structures with several coatings and fabrics, our quality-assured software solution offers you all possibilities. You too can rely on our company’s many years of experience in expert software in the field of building physics.
