Effective Use of ev80 External Venetian Blinds from Evaya

As a general rule, the ev80 is lowered in the vertical or closed (0 degrees) position and raised in the horizontal position (90 degrees). The slats can be tilted and rotated at various angles between these parameters. This may be altered, if required, with a maximum 180 degree operating range.

Blade angles can be adjusted incrementally to control solar glare and heat gain whilst allowing the entrance of natural light during summer. Conversely, during cooler months, heat and light may be directed into a building to increase passive heat gain while minimising glare.

When not in use the ev80 can be retracted and concealed in a pelmet or recess. With a range of styles and finishes available and able to be installed under eaves, within soffits or onto the faces of buildings, it is fast becoming the most effective shading solution for our climate.

To reduce heating energy requirements in winter

In the space between a window and a closed external venetian blind, an air pocket forms which prevents heat from being transported outside. Buildings with unshaded windows will emit radiation towards the outside environment and experience significant energy loss as a result.
