Façade glazing is selected for solar control, safety, spandrels, weight and allowable deflection; one build-up rarely suits the whole envelope.
Aluron / Mullion-transom façades
ATF 50
A thermally advanced 50 mm Aluron façade system for modern vertical curtain walls and roof glazing. Single-profile technology and a broad depth range provide structural flexibility.
VERIFIED PARAMETERS
A thermally efficient 50 mm grid for heavy infills.
ATF 50 offers strong thermal and weather performance, while the actual façade profile is still determined by span, grid, wind, location and glazing mass.
Visible width
50 mm
Mullion depth
30–330 mm
Transom depth
30–230 mm
Infill / glazing
up to 64 mm
Max. glass weight
up to 700 kg
Section U-value
from 0.5 W/m²K
Air permeability
AE2400
Watertightness
RE2400
Wind resistance
2400 / ±3600 Pa
With ATF 50, profile choice follows façade geometry and span. Glass, loads, mullion spacing and anchoring can require different sections across one elevation.

FAÇADE ENGINEERING
700 kg infill capacity does not remove the need for calculation.
High system capacity provides freedom, but each façade grid requires its own check of deflection, glass support and anchoring to the building.
01
Sections
Mullion and transom depths are selected by structural calculation, not appearance.
02
Infill
Glass weight and size determine supports, local stress and installation technology.
03
Weather sealing
Internal drainage, joints and perimeter interfaces are designed for the actual building exposure.
BIFORIUM / PRACTICE
A system only works as a whole with glass, hardware and installation.
Anchors, movement joints, pressure, drainage and roof/wall junctions are part of the system, not an afterthought.
Open engineering details ↗Opening inserts, actuators and ventilation are coordinated before the façade static design is finalised.

FAQ / SPECIFICATION
Questions to close before specification.
Can the system be selected only from catalogue performance?
No. Published values help shortlist options, but the finished element still has to be checked for size, glazing, weight, hardware, loads and installation detail.
Does every opening need the same glazing build-up?
Not necessarily. A south-facing elevation, a bedroom near traffic, a large fixed pane and an entrance leaf can require different glazing within the same project.
When should the installation detail be coordinated?
Before the final order. Finished-floor level, insulation, waterproofing, structural support and drainage can change the frame, threshold or final manufacturing size.
HOW TO READ THE DATA
Six values that shape the result.
A catalogue maximum is not the rating of every fabricated element. Classes depend on size, opening scheme, glazing, hardware and the tested configuration.
