Double-glazed units take approximately two to three days to order, and all our units come with a manufacturers guarantee. If requested, we can replace the vacuum between the glass panes with a layer of Argon gas, to further facilitate heat management. We can also supply and install triple-glazed units on request for London and the local area.

How is glass made?
Molten glass is formed by heating up a combination of silica and sodium carbonate, with added lime, magnesium oxide and aluminium oxide, to form soda-lime glass. This is then rolled down a bed of molten tin that has been subjected to a atmosphere of nitrogen and hydrogen to prevent oxidization of the tin.
This molten glass is then cooled and cut by machine using a diamond cutter, and then subjected to nitrogen gas at high pressure to give it a shiny finish. Glass created using this method is called “float glass”, which is name used for the “normal” glass used you find in glass installations today.
