Double Glazing

Double Glazing

Double glazing is a widely popular and extensively used feature in the United Kingdom’s residential and commercial buildings. One of the primary reasons for the widespread adoption of double glazing in the UK is its ability to improve energy efficiency. By reducing heat loss during winter and heat gain during summer, double-glazed windows help to create a more comfortable living environment while reducing the reliance on heating and cooling systems. This translates to energy savings and lower energy bills for homeowners and businesses.

Features of

Double Glazing

Two Glass Panes

Double-glazed units consist of two glass panes that are separated by a sealed space, typically filled with air or an inert gas like argon. The use of two glass panes provides added insulation and creates a barrier against heat transfer, noise, and other external factors.

Insulating Air Gap

The sealed space between the glass panes in this type of glazing acts as an insulating air gap. This gap helps to reduce heat transfer, minimizing heat loss during colder months and heat gain during warmer months. The air or gas within the gap provides additional insulation, enhancing energy efficiency and thermal comfort.

Low-E Coating

Many double-glazed windows feature a Low-E (low-emissivity) coating on one or both of the glass panes. This coating helps to reflect heat into the room while allowing natural light to pass through. It improves the thermal performance of the windows, reducing heat loss and enhancing energy efficiency.

Space Bar

The two glass panes in double glazing are separated and supported by a spacer bar. The spacer bar is typically made of a low-conductive material, such as aluminium or warm-edge composite, which helps to maintain the integrity of the sealed space and prevent heat loss through the edges of the windows.

Argon Gas Filing

In some cases, the sealed space between the glass panes is filled with an inert gas, such as argon or krypton. These gases are denser than air and provide better insulation properties, further improving the energy efficiency and thermal performance of the double glazing.

Benefits of

Double Glazing

Energy Efficiency

Double glazing significantly improves energy efficiency by creating a thermal barrier between the interior and exterior of a building.

Thermal Efficiency

It helps to minimize drafts, cold spots, and condensation on windows, ensuring a cosy and pleasant living or working space all year round.

Noise Reduction

The additional layer of glass acts as a sound barrier, minimizing the transmission of external noise into the building.


With Double Glazing, the presence of two glass panes and a sealed space makes it more difficult for intruders to break in.

Condensation Reduction

Double-glazed windows prevent warm indoor air from coming into contact with the cold surface of the outer glass pane.

UV Protection

Double glazing can provide UV protection by blocking a significant portion of the sun’s harmful ultraviolet (UV) rays.
