Example of our glazing services
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 is then cooled, and cut by machine, and then subjected to nitrogen at high pressure, to give it a shiny finish. Glass created using this method is “float glass”, which is name used for the “normal” glass used you find in glass installations today.

Express Hanwell glaziers offer a complete double glazing service including a local double glazing installer, double glazing repairs and Hanwell replacement double glazing.
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 Hanwell and the local area.
