GLASS ENGINEERING / BIFORIUM
HOW AN IGU WORKS
An IGU is not simply several panes. It is a sealed construction in which each layer addresses heat, sun, safety, acoustics or mechanical stability.
LOGIC
How we read the task.
Outer pane
Takes wind and solar load and may require heat treatment or solar-control coating.
Cavities
Width, gas and spacer affect Ug and edge-zone temperature.
Middle pane
Separates cavities in a triple IGU and may require heat treatment in large formats.
Inner pane
Low-E coating, lamination or an acoustic build-up follows the room requirements.

FAQ
Short answers.
Is triple glazing always warmer?
Not automatically. Coatings, cavity width, gas, spacer and real dimensions matter, while added thickness increases mass.
Why use argon?
It reduces heat transfer within a sealed cavity compared with ordinary air.
Why is the glass edge colder?
The spacer creates an edge zone with different conductivity. A warm-edge spacer reduces that effect.
GLASS / START
Need an IGU build-up for a project?
Send elevations, dimensions and room requirements. We will separate solar, thermal, safety, acoustic and installation criteria.
