“The installation of these inflector blinds have reduced the heat entering Lismore Library through the windows on every floor. My office windows face south and in summer the heat coming from the sun in its south-westerly position made the room very uncomfortable, even with air conditioning. Now, with these blinds, the room is at the set room temperature, even in the afternoon. The public areas of the Library are comfortable, and the blinds have also taken the glare from the windows, allowing those using their devices to do so in comfort."

– Lucy Kinsey – Head Librarian, Lismore Regional Library NSW
