How Are Double Glazing Units Made?
Double glazed windows have been used for many years. Double glazing has been a cornerstone of modern home design for over 50 years, helping homeowners enjoy warmer, quieter, and more secure living spaces. First introduced to the market in the 1970s alongside uPVC window frames, double glazing revolutionised the way homes are built and remains a standard feature in contemporary construction.
Thermal Insulation
A glass system known as double glazing employs two panes of glass with a thermally insulating space between them. When compared to single glazing alternatives, double glazing offers remarkable levels of thermal efficiency whether it is utilised in a window, conservatory, or front door. There is a significant reduction in heat loss throughout the house thanks to double glazing, which offers U-values that are at least five times lower than those of single glass.
Noise Cancellation

Comparing double glazing to single glazing reveals a significant reduction in noise. Single glazing leaves homes far more exposed to the constant sounds of the outside world, as a single pane of glass offers very little sound insulation, particularly when paired with the older timber frames common in homes built before the 1970s. Double glazing uses two panes of glass separated by a thermally insulating gap, creating an additional barrier that sound must travel through. As sound vibrations pass through denser materials, they naturally lose energy, meaning far less noise reaches the inside of your home. The result is a quieter, more comfortable living environment, one where you can enjoy everyday life without worrying about outside disturbances or disturbing your neighbours.
What Is Their Method?

How then do the powerful create this very significant and impactful home improvement? Although it’s not as complicated as you may imagine, there is a regular procedure and it does need some thought. We at Ecostar want to make sure that all of our clients are knowledgeable about double glazing so that they can compare rates from various suppliers with us and be well-informed about the products they’re purchasing.
The procedure is as follows:
- To make sure the glass will suit the appliance, it is meticulously measured from a sizable sheet.
- Glass is carefully cut to the required standard, either manually or by a machine.
- A single double glazed unit is made by using sealant to join the pieces of glass together.
- To make sure the glass is completely clean, it is next run through the washer.
- The spacer is installed on the device after the glass has been thoroughly cleaned and cleared of dirt, enabling it to be ready for gas filling.
- The procedure is completed when the gas, often argon, fills the space between the two panes.
Although various manufacturers utilise different gases, argon and krypton are often the two options. Due to argon’s better thermal insulating qualities, the great majority of manufacturers use this gas.
Choosing The Appropriate Double Glazing For Your House
It’s crucial to acquire the correct dimensions for your double glazing since after the glass has been cut, it is quite costly to resize it, and if you go too small, a brand-new set will need to be cut. Therefore, make sure you are aware of the precise size that your unit will need.
There has never been a better moment to invest in double glazing and give your house the upgrade it needs since wood, uPVC, and aluminium now provide the home equivalent levels of thermal efficiency and noise reduction!
