The SLS BT90 louvre series from EBSA Pty Ltd is designed to deliver superior thermal and acoustic performance as well as resistance to water penetration.

SLS BT90 louvres meet the new stringent energy efficiency requirements within the NCC. The thermally broken frames and the option for double or triple glazing allow for U values as low as 2.355, with a value of around 3 achievable for clear glazing with a triple IGU.

In addition to its impressive thermal performance, the SLS BT90 has also been tested to AS2047, achieving 450Pa Resistance to Water Penetration at a span of 1740mm, while its incredibly low air filtration rate passes air infiltration requirements for air-conditioned buildings.

The SLS BT90 louvre system allows for 28-44mm IGUs and can also be glazed with an aluminium sandwich panel for an all-metal finish in blade heights of up to 500mm.

Depending on the selection of glass, the SLS BT90 can achieve values as high as Rw 44 for acoustic performance.
