We've got a small office, with one wall that faces almost exactly south-
east and is damn near entirely glass. With no aircon and a big chunk of
computer kit in the office, you can imagine what it's like at the moment!

What's the options for some kind of film for the windows to cut down on
heat transmission, whilst retaining most of the light transmission? The
building management don't want anything to be "visible" from outside - no
logos, no visible tint, etc etc.

Suggestions, please...
