Structural Glazing

Structural glass is being used more and more to transform the look of buildings in our City centres. Structural glass is manufactured using a method which increases its strength by up to 7 times, this allows it to be strong enough to safely walk on for glass flooring, walls and ceilings can be made out of it too.
The manufacturing process requires sheets of glass to be heated uniformly until it is turned into plastic, it is then cooled rapidly using jets of air, and the outer most layers nearest to the air jets cool faster and solidify first which contract as they cool down. As the centre layers try to follow they throw the outer layers into a state of compression.
It is this process that creates the incredibly strong glass that is called structural glass and as the name suggests can be used to create glass structures that look stunning and give a modern feel to any building.

Our designers create beautiful & stylish Orangeries with a classical feel that will enhance your home for many years to come! The trend for Orangeries is rapidly growing in the U.K and Orangeries are more often suitable for a kitchen or dining area, rather than being used as Conservatories. Kitchen Orangeries and Dining Room Orangeries offer you much more privacy than Conservatories and will complement particular architectural styles more easily than the Conservatory. The materials we use to construct our Orangeries are second to none and of the finest quality! Combined with the latest technology in heat retentive glass, you can rest assured that our Orangeries will bring you many years of enjoyment as well as saving you generous amounts on your energy bills.
