At the start of a New Year, Jane Embury from Wrightstyle takes a look back at the origins of the window.
The Vikings were good at a lot of things; navigating their longboats across much of the western seas and, quite possibly, discovering America 500 years before Columbus. Vikings were also traders and farmers, and many stayed in Britain 鈥� leaving their genetic codes imprinted in communities across the UK, particularly in areas closest to Scandinavia, such as the Shetland and Orkney islands. In Yorkshire alone, there are over 300 place names that denote a Viking heritage.
Despite our mental picture being that of a fearsome warrior with a horned helmet, the Vikings weren鈥檛 all bad. King Canute, who set his throne by the sea shore and commanded the tide to halt, was a Viking king who also became a king of England. He鈥檚 still regarded as having been a rather good and God-fearing monarch.
In terms of the glass industry and the English language, we have a particular reason to be grateful to the Vikings, because they were the first to give us windows. The word 鈥榳indow鈥� originates from the old Norse 鈥榲indauga鈥�, made up from 鈥榲indr鈥�, meaning wind, and 鈥榓uga鈥�, meaning eye. In some Scandinavian languages, especially Icelandic, the term still survives.
Not that there were many windows back then, or at least as we would understand them. Glass was ruinously expensive, and from the the introduction of Christianity in the seventh century, what little of it there was tended to be used for eccliestical purposes.
A quick timeline for glass suggests that its earliest use dates back to the Stone Age, to cutting tools made from obsidian 鈥� the glass that can form, for example, in the high temperatures of a volcano or lightning strike. However, despite huge advances across what is now the Middle East 鈥� and particularly Egypt 鈥� it was the Romans who first properly used glass for architectural purposes 鈥� and pretty soon windows with glass had appeared in Rome鈥檚 most important buildings.
After that not a lot happened until the 11th century when German glass craftsmen discovered a technique – then further developed by the Venetians in the 13th century – for the production of glass sheets. For a long time thereafter, it was the Venetians who dominated the glass business. It wasn鈥檛 until the latter stages of the Industrial Revolution that mass production of flat glass became possible, and not until after the Second World War that float glass came into being the optically brilliant glass that virtually all modern windows are now made from.
However, the history of glass hasn鈥檛 stopped, particularly in the development of specialist glasses 鈥� for example, to defend against fire or ballistic and blast threat, developing new glass types made from multiple sheets of glass with thermoplastic interlayers.
Wrightstyle has been at the forefront in developing glass and glazing systems to counter specific threats 鈥� traditionally, of course, designed to prevent the spread of fire and create safe escape routes for the occupants of buildings. More recently, we have also developed systems to counter the scourge of terrorism 鈥� with our latest system now tested against lorry bomb attack.
What has made us different over the years is that we can supply both the glass and its framing system, tested together to provide a complete and guaranteed solution 鈥� a huge advantage both in procurement and in satisfying stringent fire or safety regulations, particularly since our systems have been tested to meet European and American standards.
In other directions, research continues apace 鈥� from the application of nanotechnology to glass surfaces to the development of amorphous glass (glass that behaves almost like a liquid). We are pushing the boundaries of strength, solar control and optical quality to create glass types that are so advanced to be constantly challenging the imagination of architects for complex facades or large-spans of glass 鈥� all securely framed in aesthetically beautiful steel.
It was the renowned Swiss architect Le Corbusier who suggested that the history of architecture was the history of the window and, given the advances that the glass industry continues to make, it鈥檚 still an apt definition. Better that than architecture being the history of the eye-hole – something for which we must be grateful to the pillaging Vikings.
