Thirty Dichroic glass fins
Thirty dichroic glass fins, each eight metres long, stand proud of the cladding of this refurbished office building that overlooks what used to be the north side of the famous Foyles bookshop. Each 30cm wide fin responds to the changing light conditions. In full bright sunlight they appear as shown here, and from the inside show a variety of dazzling colours which vary depending on the angle of your viewpoint. The north side of the building has ten of these tall thin fins, and can be seen from a number of different vantage points. Sometimes they appear red, and at other times blue, and at other times gold. These fins are made with a dichroic film laminated between two layers of glass, which is the least expensive way of manufacturing this type of glass. Technically these are quite difficult to make as the film is extremely delicate.
