GLASS ENGINEERING / 05
THE IGU AS A SYSTEM
We select a complete glazing build-up for orientation, size, safety, acoustics and profile compatibility — not a coating in isolation.
A large panoramic opening combines several questions: reflected colour, internal surface temperature, breakage behaviour, IGU mass, production limits and the installation route.

How an IGU works
Cavities, spacer, argon, sealants, coatings and safety panes: how an insulating glass unit works as one assembly.
↗02How to read a formula
IGU formula explained: pane thickness, ESG, VSG, Low-E, Neutral, WE, Argon and layer order.
↗03Warm edge and argon
What warm-edge spacers and argon do, why the edge zone matters and how seal integrity affects IGU service life.
↗04Glass selection checklist
Glass selection checklist: façade orientation, safety, acoustics, thermal targets, dimensions, mass, heat treatment and visual compatibility.
↗CHECK
Five parameters in one build-up.
Thermal
Ug, edge temperature and installation bridge.
Solar
g-value, visible light and reflected appearance.
Safety
Heat treatment, lamination and breakage behaviour.
Acoustics
Asymmetry, laminate and airtightness of the complete element.
Mass
Hardware, supports, lifting and production formats.
GLASS / START
Have elevations and building orientation?
Send the largest openings and room requirements. We will start with the critical IGUs, then standardise the schedule where technically sensible.
