Modern double glazed windows keep the cold out and the heat in much more effectively than their single glazed counterparts. This is due to the gap between the panes being filled with argon gas which insulates against temperature transfer.
Previously metal was used to fill the gap between the panes but this reduced the effectiveness of insulating the windows as it transferred heat. Here is what you should know about double glazing:
Glass
Two glass panes create a barrier between your home and the cold air outside, slowing the transfer of heat energy and filtering out sound waves. The gap between the glass panes is filled with an inert gas, usually argon (although krypton and xenon are also available) which is better than air at resisting energy transfer.
The frame and grilles start life as extruded lengths of metal, which are quality checked before being cut to size and bent into their final shape. They may also be clad with other materials, such as wood or aluminium, although today most modern double glazing is manufactured from uPVC.
Frames
The frames of a double glazing window start out their life as extruded lengths of metal such as aluminium or uPVC. These are cut down to the correct lengths as needed by special machines and quality checked to ensure they meet the factory’s high standards.
Once cut the uPVC or aluminium are then shaped, bent and formed to fit into the frame shapes as required by the design of the windows. These are also sanded down to smooth the edges and then coated with a primer to prevent corrosion.
Grilles
Double glazed windows feature two glass panes with a gap in between, which is then filled with an insulating gas like argon. This creates a thermal cushion, reduces heat loss and blocks out sound.
The first step in making a double glazed window involves cutting the glass sheets to the required size. Window manufacturers in Glasgow have a number of high-quality solutions that allow this to be done safely and efficiently. This is a very precise process and requires great skill, or the glass sheets will shatter.
The next step involves scoring the glass sheets, which is a very delicate process. This can be done by hand or using an automated solution, such as a special saw that has a guillotine-like blade.
Sealing
Double glazing helps to reduce condensation which can lead to unhealthy mould and keeps outside temperatures from transferring through the glass. This also makes it harder for warm air to escape the room, reducing heating bills.
The gap between the two panes of glass is typically filled with air or an insulating gas such as argon. This provides extra energy efficiency and improves sound reduction.
