BT90 Thermally Broken IGU Louvre System

The BT90 is a thermally broken double, or triple glazed glass louvre system produced by Schneider Louvres in Germany. The system utilises a heavy duty rack and pinion operating mechanism concealed within thermally broken louvre frames allowing for either automated or manual operation to meet your specific project requirements.

The system can be configured with either double glazing (DGU) or triple glazing (TGU) sourced from local New Zealand suppliers allowing the louvres to be glazed to the rest of the facade.

The BT90 louvre system is certified to NZS4211 having been tested to AS/NZS4420.1. Using the correct glass selection, the BT90 louvre is capable of meeting the stringent H1 energy provision requirements recently introduced in New Zealand.

LF550 Large Format Single Glazed Louvre

The LF550 is a large format, single glazed louvre capable of achieving extremely wide spans with blade heights up to 550mm using monolithic or laminated glass ranging from 11.52mm up to 21.52mm thick.

These louvres are extremely customisable and subject to wind load, can achieve spans of 1900mm wide or (with an intermediate (blind) mullion) in excess of 3000mm.

Where compliance with H1 Energy Provisions is not required, the LF550 system is the ultimate operable facade system and has been awarded for the Commercial Bay Project in Auckland by the NZ facade industry.

MP2 Large Format Glass Louvre

The MP2 is a large format, thermally broken double, or triple glazed louvre system designed for integration into commercial curtain wall systems. This system cannot be compared to any other louvre systems, apart the single glazed LF550 louvre both share the heavy duty gearboxes and motors concealed within the 150 x 50 framing provide near silent operation.

The MP2 has established itself as the default solution for commercial projects and holds many performance records when tested to NZ 44211. This includes its ability to withstand incredibly high wind loads (partly as a result of an integrated mechanical lock on every blade), resist the penetration of water (up to 800 Pascals) and pass air infiltration for air conditioned spaces.

The system is available as a framed system using standard IGU’s or as a frameless system using stepped IGU’s. Spans of up to 1500mm wide are possible to any wind category in New Zealand and wider spans can be implemented utilising an integrated blind (centre) mullion.

Fixed Louvre Brackets

EBSA offers a range of fixed louvre brackets ideal for enclosing winter gardens and other spaces. The brackets are designed for simple installation to an existing or new structure and can be glazed with 8 - 12mm glass.

The maximum span is dependent on blade height, project wind load and of course the nominated glass makeup. The system is fully engineered and we are happy to assist you with developing your designs to maximise performance and aesthetics in the most economical configuration.

Standard Brackets are supplied in a clear anodised finish and other colour options are available on request. Get in touch with us today to find out more about the benefits of the louvres in our range.
