LF550 Large Format Frameless Glass Louvre

EBSA, We make buildings breathe

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 around 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 by the NZ facade industry for the Commercial Bay Project in Auckland. To speak to our expert team about installing this product, contact our expert team today.

Advantage and Benefits

  • Large format frameless glass louver system with blades up to 500mm high
  • Louvre mechanisms are integrated into the 50mm vertical frame profile width
  • The operating mechanism is only visible when the blades are opened
  • Opening angle variable up to 80°
  • Blades are end pivoting and glass is positioned in front of the mullions allowing for a ‘continuous’ span of up to 3300mm
  • All glass look as viewed from outside due to louvre frame positioning behind the glass blades
  • Glass is fixed via patch fittings
  • Automated or manually operated, 24VDC louvre drives can be fully concealed
  • Available as a complete system with head and sill and full perimeter seals
  • The system accommodates a range of glass sizes, currently 12 – 13.52mm, 17.52mm and 21.52mm
  • Centre pivot
  • Top pivot
  • Single glazed
  • Double glazed
  • Triple glazed
  • Framed
  • Frameless

The LF550 is designed so that all of the operating mechanisms are concealed when the louvre is closed, it mimics the appearance of fixed glazing.

When the system is opened the large format blades and extremely clean lines provide a very modern sophisticated aesthetic unlike almost any other louvre system on the market.

In addition to the visual impact, this louvre system has unrivalled performance with NATA certified AS2047 testing up to 1973mm wide achieving 700 pascals resistance to water penetration.

Using an integrated blind intermediate mullion it is possible to span the glass to approx 4500mm wide allowing even greater flexibility to building designers.

Each LF550 is manufactured to the highest of standards and is installed by EBSA’s highly experienced and  dedicated team ensuring every system sold is fully commissioned by us - our promise of quality.
