Tetrix fins are fabricated from pre-coated aluminium to an aerofoil profile with end pins and side channels. They can be a fixed brise soleil or operated to adjust the louvre angle enabling control of solar gain and glare from different sun angles.

​

Louvre sizes are 210 and 300mm that can span up to 4.5m without horizontal support and 6m when fitted vertically. Robustly constructed Tetrix fins are a very effective and functional sun screen that will be a significant feature on your building.

​

Although manual operation is possible, they would usually be motorised to open and close and be linked to the Building Management System.
