Trojan external venetian blinds are the most efficient and flexible form of solar control. With the External venetians closed as little as 3% of the solar gain will be transmitted through the glass.

 

This reduces the air conditioning load or eliminates the need for it allowing healthier natural ventilation. In occupied areas external venetian blinds with the louvres in the 45° working position Trojan blinds will still reduce solar gain by over 90% Correctly adjusting to that position, the louvre angle of the External venetian Trojan blind 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.

 

They also control diffuse light thus eliminating glare without impeding ventilation.

​

The external venetian blinds can be raised in the winter to enable beneficial gains on sunny days.

​

The heavy-duty louvres are held in position with side guides or cables. They can be manually operated from within the building but are normally motorised.

​

All remotely controlled from the interior either with a manual rod or an electric motor and in colours to make a statement or blend with the façade. To be most energy efficient there are many combinations of automated control by sun, light, wind or timer. External venetian trojan blinds can also be linked to a BMS or Home Management System.
