MP2 GLASS LOUVRE SYSTEM
MP2 large-format glass louvres for insulated facades.
MP2 combines substantial operable blade scale with thermally broken system architecture and insulated glazing for commercial facades where the louvre forms an integrated part of the building envelope strategy.
The system can be developed in structurally glazed SGI and framed insulated-glass configurations. EBSA coordinates the louvre geometry, glass, facade interfaces, automation and controls around the project from early selection through installation and commissioning.
Large-format architectural expression developed as part of the facade system.
LARGE FORMAT
Large insulated-glass blades supported through the vertical frame for substantial blade scale and a clean architectural expression
THERMALLY BROKEN
Thermally separated frame and blade-holder architecture
INSULATED GLAZING
Double- and triple-glazed system pathways for conditioned facades
AUTOMATION INTEGRATED
Concealed drive and operating transmission coordinated with controls and building interfaces
SYSTEM SELECTION
Choose MP2 when large blade scale and the insulated facade strategy need to be developed together.
MP2 occupies a distinct position in the EBSA glass louvre range. It provides a large-format thermally broken pathway for projects that need insulated glazing, substantial operable blades and a highly integrated facade solution.
MP2
MP2
Large-format insulated-glass louvre architecture with thermally broken framing and end-supported, end-pivoting operation.
LF550
Large-format single-glazed end-pivoting architecture where transparency and a frameless external expression are the leading requirements.
BT90
A dedicated thermally broken centre-pivot insulated-glass pathway where the framed louvre architecture suits the facade brief.
G SERIES
A single-glazed centre-pivot family spanning the supported G-S, frameless overlapping G-BS and flush stepped-laminate G-FS configurations.
Start with the required facade architecture. Use the product family that best fits it.
INSULATED LOUVRE ARCHITECTURE
Large insulated-glass blades supported, driven and locked through the vertical frame.
Each MP2 blade is a substantial insulated-glass facade element supported at its ends by the MP2 blade-holder and pivot hardware. The load path continues through the vertical frame or intermediate mullion into the perimeter fixing and surrounding facade, while the operating transmission and blade-locking components are coordinated within that same frame zone.
MP2 SGI
A stepped insulated glass unit extends across the external face to create a structurally glazed expression. From outside, the glass becomes the dominant reading of the blade while the thermally broken blade-holder, pivot and operating components remain behind the glass line.
MP2 FRAMED
A thermally broken framed blade-holder visibly captures the insulated glass unit, giving the same large-format operating architecture a more defined framed expression.
THERMALLY BROKEN FRAME + BLADE SUPPORT
Thermal separation is incorporated through the aluminium frame and blade-holder architecture as an integral part of the insulated facade strategy.
END-SUPPORTED, END-PIVOTING OPERATION
Each glazed blade is supported and rotates at its ends, concentrating support, pivot and movement within the vertical framing zone and enabling substantial insulated-glass blade scale.
CONCEALED DRIVE + TRANSMISSION
The drive acts through the integrated operating system inside the frame to move the blades together. The motor, gearing and linkage remain concealed from the primary architectural sightline.
INDIVIDUAL MECHANICAL BLADE LOCKING
In the closed position, each blade is mechanically interlocked within the operating system. The locking action, seals, blade support and frame therefore work together as part of the complete closed assembly.

BUILDING STRUCTURE
CONCEALED OPERATING ZONE
The defining MP2 idea is the complete assembly: insulated glass blade, end supports, thermal breaks, concealed operating mechanism, locking and facade frame working as one system.
DESIGN INPUTS
Coordinate the glass, blade proportion and facade detail early.
Large-format insulated louvres bring several facade decisions together. Overall louvre size, blade span, blade height, glass makeup, intermediate support, perimeter framing and operating geometry all influence how the completed MP2 assembly performs and how it integrates visually with the building.
INSULATED GLASS UNITS
MP2 supports double- and triple-glazed insulated-glass pathways. The project glass is coordinated with the louvre system around the required thermal, structural, visual and coating strategy.
BLADE SCALE + PROPORTION
Larger blades reduce visual subdivision and create a stronger architectural rhythm, with span, glass weight and operating forces resolved as part of the system design.
OVERALL LOUVRE GEOMETRY
Width, height and aspect ratio matter. A tall louvre and a wide louvre can place materially different demands on the same system architecture.
INTERMEDIATE SUPPORT
Where the project requires a wider overall louvre field, an intermediate mullion can form part of the engineered configuration. Its structural and visual role should be resolved with the surrounding facade.
PERIMETER INTERFACE
Coordinate the MP2 frame with curtain wall, cladding, waterproofing, drainage, fixings, construction tolerances and adjacent facade components before the system reaches site.
Geometry is a core part of the engineering evidence and product selection.
FULL-SIZE PERFORMANCE
Independent full-size testing demonstrates MP2 performance at commercial facade scale.
EBSA’s current MP2 test programme was carried out by ift Rosenheim in Germany for Australian requirements, using AS/NZS 4420.1:2016 and the performance requirements of AS 2047:2014+A2:2017.
The programme includes tall and wide full-size MP2 SGI assemblies, giving architects and facade engineers current evidence across the large-format geometries used in commercial facade design.
TESTED SIZE — TALL
1500 × 3750 mm
Full-size MP2 SGI tall configuration.
TESTED SIZE — WIDE
2800 × 2800 mm
Full-size MP2 SGI wide configuration.
WATER RESISTANCE
1000 Pa
No water penetration at test pressures up to 1000 Pa.
AIR INFILTRATION
0.40–0.45 L/s·m²
Approximately 0.40–0.45 L/s·m² at ±75 Pa across the current MP2 programme.
SERVICEABILITY
UP TO ±1800 Pa
Deflection remained within l/250 at test pressures up to ±1800 Pa.
ULTIMATE STRENGTH
+10,000 / -6,500 Pa
Ultimate testing reached up to +10,000 Pa / -6,500 Pa.
The 2026 programme gives MP2 a strong current Australian-standard performance baseline for large insulated operable facade applications.
PROJECT APPLICATION
Use the tested performance as a strong foundation for project design.
MP2 is a repeating facade system. EBSA uses the current test programme together with project geometry, glass makeup, blade span, design pressure and support strategy to develop the final louvre arrangement.
Large louvre fields can be developed from repeating MP2 elements, with intermediate mullions used where required to create wider facade zones while maintaining the architectural intent and structural load path.
01 — BLADE SPAN + GLASS
Coordinate blade span and glass makeup with the required wind pressure, thermal strategy and visual outcome.
02 — HEIGHT + FIELD WIDTH
Develop tall single fields or wider repeating fields to suit the facade geometry and architectural rhythm.
03 — MULLION STRATEGY
Use intermediate mullions where required to create wider louvre fields and carry blade and support loads into the surrounding facade.
04 — PERFORMANCE DESIGN
Use the current water, air, serviceability and ultimate results as the engineering baseline for project selection.
05 — EBSA ENGINEERING
Coordinate louvre geometry, glass, support arrangement and facade interfaces with the project’s performance requirements.
Full-size testing and project-specific facade engineering work together to give project teams confidence in the final MP2 solution.
AUTOMATED MP2 LOUVRES
Design the louvre and its operating system together.
MP2 is often selected for facades where the louvres operate as part of natural ventilation, smoke control or a wider building strategy. EBSA coordinates the mechanical louvre system, actuation, wiring, controls, sensors and building interfaces as one operating facade system from the outset.

SERVICE
NATURAL VENTILATION
Coordinate blade position and opening strategy with user control, environmental inputs, weather response and the building’s natural-ventilation sequence.
SMOKE CONTROL
Where MP2 forms part of a smoke-control or relief-air strategy, coordinate the required emergency operating sequence and fire-system interfaces with the louvre and control architecture.
BMS + MECHANICAL
Define commands, status, overrides and interlocks around the building’s required operating sequence.
MAINTENANCE + LOCKOUT
Consider cleaning access, service access, adjustment and maintenance lockout as part of the operating facade strategy.
The louvre, mechanism, controls and building interfaces should resolve as one operating facade system.
FROM PRODUCT TO FACADE
Carry the MP2 architecture through detailing, installation and commissioning.
EBSA carries the selected MP2 configuration into the surrounding facade and construction detail, coordinating louvre geometry, glass, support, waterproofing, automation and construction sequence so the finished system can be installed, adjusted, commissioned and maintained as intended.
01
FACADE DETAILING
Resolve perimeter profiles, adjacent curtain wall or cladding, seals, drainage paths, support and tolerances around the actual project condition.
02
GLASS COORDINATION
Coordinate glass makeup, coatings, appearance, edge conditions and procurement with the wider facade glazing strategy.
03
SHOP DRAWINGS
Develop project-specific drawings that communicate the louvre arrangement, facade interfaces and relevant automation requirements to the project team.
04
INSTALLATION + ADJUSTMENT
Plan access, sequence, glazing, adjustment and final operating checks around the actual finished-facade and site conditions.
05
COMMISSIONING + SERVICE
Where automated, verify the completed MP2 system through the required controls, interfaces and operating sequence, then retain a clear service pathway for the building lifecycle.
A large-format louvre is successful when the architectural detail and operating system remain coordinated through delivery.
MP2 IN BUILT FACADES
Large-format insulated louvres integrated into commercial architecture.
FEATURED PROJECT
151 CLARENCE STREET — SYDNEY
MP2 integrated into the commercial facade.
MP2 architectural glass louvres are integrated into the completed 151 Clarence Street facade, demonstrating the insulated large-format product pathway in built form and the relationship between blade scale, glazing and the surrounding facade architecture.
150 LONSDALE STREET — MELBOURNE
Thermally broken MP2 louvres within a completed city facade.
The 150 Lonsdale Street project provides another built reference for MP2 thermally broken glass louvres integrated into the completed city facade.
111 BOURKE STREET — MELBOURNE
MP2 louvres coordinated with facade controls.
At 111 Bourke Street, MP2 glass louvres were delivered together with CPS-M control panels, connecting the architectural louvre system with the wider facade-automation strategy.
SPECIAL MP2 CONFIGURATION
A separate MP2 pathway developed around opposing blade movement.
MP2 Opposed Opening extends the product family into a project-specific louvre architecture where opposing blade movement is used to address a different combination of views, ventilation, weather protection and facade expression.
The system was developed for 1 Hotel Melbourne through a two-year project collaboration and is presented as a dedicated MP2 design pathway for projects requiring opposing blade movement.
The standard MP2 pathway covers the insulated large-format system, while MP2 Opposed Opening provides the dedicated architecture for projects requiring opposing blade movement.
