Why use External Shutter blinds?

Unlike internal Venetian blinds, our external venetian options reflect heat away before it reaches your windows, providing superior temperature control and energy efficiency.


With the louvres closed,  gain will be transmitted through the glass. This reduces use air conditioning, allowing for natural ventilation.


In occupied areas external blinds with the louvres in the 45° working position our Trojan blinds will still reduce solar gain by over 90%

Adjusting the External Trojans to the correct position, the louvre angle considerably improves the distribution of daylight, reducing high levels of light intensity close to the window and increasing light in the deeper recesses of the room.
