Saint-Gobain Glass has launched Calumen, a free online glass configuration and specification tool, designed to help window fabricators and glass processors select the right glass for their residential and commercial projects.

Calumen – a combination of ‘calculation’ and ‘lumen’ – is the first online tool from the company’s new collection of digital services Calumen Suite and replaces the former CalumenLive service.

According to Saint Gobain, it has been completely redesigned and will provide new functionalities through a user-friendly interface.

Calumen is a digital simulation program that calculates the required technical performance and ‘comfort’ factors that are most important to glazing projects, such as minimum light transmission, maximum solar heat gain, high performance acoustics, low external light reflectance or a host of other options. It calculates the performance of any single glass or combination of glass types and thicknesses.

New functionality includes the ability to compare multiple glass types, duplicate previous specifications, render illustrations, view certifications and utilise a comprehensive acoustic database. As a cloud-based system, Calumen updates automatically, ensuring the next time you login, you have access to the very latest product information and technical data.

Available in 13 languages, new Calumen is available at www.calumen.com.

Beyond this initial launch, Saint-Gobain Glass says it will gradually add new services and functionalities to the Calumen Suite.
