External Venetian Blinds

External venetian blinds offer thermal comfort whilst allowing ultimate control of light. Fully retractable, the blinds can be specified with a range of different slats and settings to optimise light whilst reducing solar gain.

The AR63 or AR92 type venetians are perfect for residential projects providing full blackout and come in a choice of S and Z shaped slat. For commercial properties, the ARB80 is a popular choice which allows the upper part of the venetian curtain to be open whilst the lower part of the system remains closed, reducing glare to work on screens.

A key consideration when specifying a venetian blind, is the available height and depth above the glazing to accommodate the system. Larger slat sizes like the AR92 which is a 92mm slat offer more light and less height but require more depth. The opposite applies for the AR63 which is a 63mm slat and requires more height and less depth.

There are options to increase wind resistance and a multiple choice of covers and fixings to conceal the head of the blind for retrofit installations.

For new build, the external venetians can be flush mounted concealing the head of the blind and side guides. Dummy boxes can also be specified which are installed during the construction phase, to ensure there is enough space to fit the system. This is common in mainland Europe, where residents may chose to purchase external venetians after the build is complete.

External venetians are an ideal solution to comply with the new part B fire regulations, as aluminium is non-combustible and a special non flammable powder coating can be applied.
