Design freedom: clean glass volumes, corners and roofs without visible structure dictating the facade grid.
Composite insulating glass unit.
Evolution of insulating glass technology.

Problem and solution
Conventional facade systems rely on visible structural mullions. IGU+ enables cleaner envelope geometry with less visible metal and more architectural freedom.

What it gives
01
More glass
Larger uninterrupted glass surfaces and wider transparent spans.
02
Less metal
Load paths move into the unit edge — visible aluminium is minimised.
03
Reduced system depth
Slimmer build-up frees interior space and lightens the envelope.
04
New architectural opportunities
Corners, folds and cantilevers that conventional systems cannot offer.
05
Where it is used
-
Frameless facades
Clean facade language with minimal visible structure and stronger architectural rhythm.
-
Transparent roofs
Large-span daylight roofs for atriums, galleries and public interiors with reduced visual noise.
-
Bay and panoramic windows
Corner and panoramic glazing with cleaner framing and better visual continuity.
-
Modular facades
Prefabricated envelope logic adapted to modular workflows and fast construction cycles.
-
Pavilions
Lightweight transparent skins for compact public architecture and branded pavilion formats.
-
Double skin
Outer and inner glass envelopes for climate buffering and controlled energy performance.
-
Cantilever glazing
Projecting glazing compositions that keep visual lightness while extending usable envelope depth.
06
For whom
More daylight and a premium envelope per square metre — a facade that differentiates the asset on the market.
Fewer components and reduced system depth simplify fabrication, logistics and installation on site.
Documented performance data and engineering support from feasibility studies to detailed design.
07
Validation
Testing
Structural and climatic load testing of composite units in accredited laboratories.
Patents
Patented unit composition and edge-connection technology.
Certification
Compliance and certification for facade applications across target markets.
