Structurally glazed appearance
Stepped insulated glass units provide a frameless external glass expression while retaining the strength and thermal separation of the concealed blade-holder system.
Architectural Glass Louvres
MP2 Thermally Broken Glass Louvre System
A large-format, end-pivoting operable glass louvre system combining thermally broken framing, insulated glazing and concealed motorised operation for commercial façades.
MP2 is available as MP2 SGI, using stepped double- or triple-glazed units to create a frameless external glass appearance, or as MP2 Framed, using standard insulated glass units within thermally broken aluminium blade holders.
The motor, gearboxes, pushrods, blade-locking mechanisms and operating components are concealed within the system framing. Removable aluminium access covers provide direct access for inspection, adjustment and maintenance.
EBSA can support the complete delivery pathway, including system selection, glass coordination, façade interfaces, actuators, control panels, installation, glazing, programming, commissioning and ongoing service.
Large-format insulated-glass blades with concealed operation
MP2 is intended for commercial façades where large operable glass openings, insulated glazing and a high level of architectural integration are required. Each blade is end pivoting and supported by a purpose-designed operating mechanism contained within the vertical framing.
Integrated gearboxes, pushrods and a concealed 24 V DC motor operate the blades together as a coordinated opening. Mechanical locking secures the blades when closed, supporting air and weather sealing and resistance to movement under wind pressure.
Integrated blade locking
Each blade incorporates mechanical locking as part of the operating system, supporting security, weather performance and resistance to project design loads.
MP2 SGI system features
- Large-format end-pivoting operable glass louvre system
- Thermally broken aluminium framing and blade-holder system
- Double- or triple-glazed insulated glass units
- Stepped IGU construction for a structurally glazed external appearance
- Heavy-duty gearboxes integrated within the vertical framing zone
- Mechanical locking incorporated at each blade
- 24 V DC automated operation or manual operation, subject to configuration
- Suitable for integration with BMS, natural ventilation and smoke-control systems
- Blade cleaning and maintenance access from the internal side
- Anodised or powder-coated aluminium finishes

MP2 SGI or MP2 Framed
Both MP2 configurations use the same thermally broken perimeter framing, concealed operating system and end-pivoting blade geometry. The principal difference is how the insulated glass is retained and presented externally.
MP2 SGI
MP2 SGI uses stepped insulated glass units that extend in front of the blade supports and operating frame.
Ceramic frit and structural silicone conceal the blade-retention components, producing a clean, frameless external glass appearance.
- Stepped DGU or TGU glazing
- Frameless external appearance
- Concealed blade supports
- Continuous architectural glass expression
- Double- or triple-glazed configurations
MP2 Framed
MP2 Framed uses standard insulated glass units retained within thermally broken aluminium blade holders.
It provides a clearly expressed framed-blade appearance while retaining the MP2 perimeter framing, concealed operating mechanisms and integrated blade locking.
- Standard DGU or TGU glazing
- Thermally broken framed blade holders
- Defined horizontal blade framing
- Double- or triple-glazed configurations
- Compatible with coordinated façade framing
MP2 SGI is normally selected where a structurally glazed external appearance is important. MP2 Framed is suited to projects where expressed blade framing or standard insulated glass units are preferred.
Full-size MP2 configurations tested by ift Rosenheim
Two full-size MP2 configurations have been tested by ift Rosenheim in Germany to NZS 4211:2008, Specification for performance of windows, incorporating Amendment 1:2014. The testing used the procedures in AS/NZS 4420.1:2016, Windows, external glazed, timber and composite doors — Methods of test — Part 1: Test sequence, sampling and test methods.
ift Rosenheim is an internationally accredited testing and certification institute specialising in windows, façades, doors, glass and related building-envelope systems.
1500 mm wide × 3800 mm high
A tall single-span MP2 SGI configuration representative of full-height commercial façade applications.
2800 mm wide × 2800 mm high
A wide MP2 SGI configuration developed to assess a larger-format façade arrangement.
Project-specific performance is reviewed against the proposed dimensions, glass makeup, support arrangement and design pressures.
Testing by ift Rosenheim provides independent evidence for the two full-size configurations. EBSA reviews each proposed MP2 arrangement against the applicable report, glass design, support conditions and project design pressures.
High-performance operable façade technology
MP2 systems have also undergone project-specific testing in Australia for water penetration, air infiltration, structural loading and cyclonic debris impact. These results provide additional technical evidence for the applicable tested arrangements.
| Performance area | Available MP2 evidence |
|---|---|
| Water penetration | Project-specific testing completed up to 1000 Pa for the applicable tested configuration. |
| Air infiltration | Available project testing recorded zero air leakage at the AS 2047 benchmark pressure of 75 Pa for the tested arrangement. |
| Ultimate strength | Testing exceeded the rig capacity, with certification recorded at +11 kPa and −10.3 kPa for the applicable specimen without product failure. |
| Cyclonic debris impact | Testing completed for debris types A and B for the relevant project configuration. |
Performance values apply to the tested specimen and configuration. EBSA confirms the relevance of available evidence during project selection and technical review.
Project-configured glazing, framing and operation
MP2 is configured for the individual façade. Final dimensions, glazing, blade arrangement, design pressures, supporting structure, motor system and controls are coordinated before manufacture.
| System element | MP2 configuration | Project coordination |
|---|---|---|
| Perimeter frame | Nominal 144 × 50 mm thermally broken aluminium framing. | Head, sill, jambs, mullions, supports and fixings are coordinated with the surrounding façade system. |
| MP2 SGI glazing | Project-selected stepped double- or triple-glazed insulated glass units. | Glass thickness, step, frit, silicone bite, edge construction and coatings are coordinated with the approved glass supplier. |
| MP2 Framed glazing | Project-selected standard double- or triple-glazed insulated glass units. | Glass makeup is selected against the blade holder, glass weight, dimensions, safety requirements and thermal design. |
| Blade height | Typically approximately 280–500 mm. | Selected against appearance, glass weight, ventilation area, structural performance and operating loads. |
| Single-bay width | Typically approximately 650–1500 mm. | Final width depends on glazing, design pressures, blade height, framing, supports and relevant test evidence. |
| Wider arrangements | Multiple operating bays using a blind intermediate mullion behind the glass line. | The mullion supports adjoining bays while maintaining a coordinated external glass composition. |
| Opening arrangement | End pivot with opening angles up to approximately 70 degrees. | Final opening angle depends on glass geometry, free-area requirements, operating loads and available clearances. |
| Electric operation | Concealed 24 V DC motor connected to integrated gearboxes and the coordinated blade-operating mechanism. | Electric operation is the normal configuration for natural ventilation, mixed-mode ventilation and smoke-control applications. |
| Manual operation | Available only for selected configurations following technical review. | Suitability is confirmed against the proposed size, blade weight and arrangement. |
| Finish | Anodised or powder-coated aluminium profiles. | Selected to coordinate with the surrounding curtain wall, glazing or façade finish. |
Continuous seals with maintainable concealed mechanisms
MP2 uses continuous perimeter seals at the head, sill and jambs together with horizontal seals between adjoining glass blades. The glazing and aluminium framing operate as one coordinated weather-sealed assembly.
Removable aluminium access covers provide direct access to the concealed motor, gearboxes, pushrods, locking components and adjustment points without dismantling the surrounding façade.
Insulated glazing for conditioned façades
MP2 SGI combines thermally broken framing with double- or triple-glazed insulated glass blades. The final thermal performance depends on the glass makeup, spacer, coatings, gas fill, blade dimensions, frame configuration and complete façade arrangement.
Where MP2 SGI forms part of a conditioned thermal envelope, the selected configuration should be included in the project’s H1 assessment and coordinated with the wider curtain-wall or window-system design.
Large-format insulated-glass louvres in completed façades
MP2 can be integrated into curtain walling, punched window openings and larger operable-façade zones. The images below show the scale, glass expression and architectural character of the system across completed commercial projects.
MP2 SGI louvres integrated into a smoke-control system
EBSA supplied MP2 SGI structurally glazed double-glazed louvres for installation by Thermosash at Auckland Airport Domestic Processor as part of the project smoke-control system.
EBSA also designed, built, installed and programmed the CPS-M control panels and coordinated the louvres, actuators and project interfaces with the architect, engineers and wider delivery team.
The project demonstrates how MP2 SGI can combine insulated glazing, a clean external glass expression and coordinated smoke-control automation within a major commercial façade.
Integrate MP2 with the building-control strategy
MP2 can be automated for daily natural ventilation, purge ventilation, BMS-controlled façade operation and project-specific smoke-control functions. Depending on the wider design, the louvres may provide pressure relief, low-level make-up air or natural smoke exhaust.
EBSA can select and coordinate the actuators, control panels, switches, sensors, weather inputs, fire-alarm interfaces, BMS interfaces, programming and commissioning.
