CROWN Doors International has a Double Glaze Venetian Blind unit which has the venetians completely sealed within two layers of toughened safe glass. This means the venetians do not require any cleaning or maintenance as no dust, dirt or contaminates can get into the sealed units.
The control for tilting, raising and lowering the venetians is via a strong magnet which is situated on the outside of the glass. By sliding the magnet up and down, the venetian will open and close and raise and lower.
The magnetic controls can be supplied loose whereby a nurse, a school teacher or a person of authority will have total control in the operations of the venetian blinds.
The Double Glaze Venetians have been tested by the Optometry and Vision Science at the University of New South Wales. The test results have shown a maximum solar heat gain coefficient of 0.16.
