What are double glazed windows?
Double glazed windows are one of the most popular window options available on the market today. They are made up of two or more separate panes of glass that are hermetically sealed and filled with air or inert gas, creating a layer of insulation between the inside and outside of your home.
This design improves the windows’ ability to insulate heat and sound, increasing the energy efficiency and acoustic comfort of your home. Windows can be made from different types of glass depending on your specific needs.
In addition, double glazed windows are available in a variety of styles and sizes, including triple-glazed models or with custom finishes to match the design of your home.
The advantages of thermopane windows
One of the best decisions you can make when it comes to renovating or building a home is installing double glazed windows . These insulating windows are one of the best solutions for a comfortable, energy efficient and economical home.
Double glazed windows are an excellent choice for anyone looking to improve the comfort and energy efficiency of their home. Here are some of the most important advantages that you benefit from when you choose double glazed windows :
| Benefits | Description |
|---|---|
| Energetic efficiency | Double glazed windows provide superior thermal insulation, reducing heat loss through the glazing and minimizing the need for additional heating in the cold season. At the same time, these windows can prevent excessive heat from entering the home during the summer and reduce electricity consumption. |
| Sound absorption | Double glazed windows provide excellent sound insulation, reducing outside noise and ensuring a quiet and comfortable environment inside. |
| Durability and safety | Another major advantage of double glazed windows is their resistance to wear and tear and different weather conditions, being less vulnerable to damage than traditional wooden windows. They are also more secure, having a higher degree of burglary resistance than plain glass. |
| Aesthetic appearance | Double glazed windows are available in a wide variety of styles and colors and can be customized to perfectly match the design of your home. |
| Long-term financial economy | By choosing double glazed windows , you benefit from long-term financial savings, as they require less maintenance, last longer and reduce the costs of heating and cooling your home. |
Considering the advantages outlined above, it is clear that investing in double glazed windows is an excellent decision for anyone looking to improve their home. In the next section of this guide to double glazed windows, we’ll take a closer look at the materials used to make them, to help you make the best choice for your needs.
Materials used for double glazed windows
Double glazed windows are made of several materials, but the most used are PVC joinery and aluminum.
PVC joinery is a durable and easy-to-maintain plastic material that is very popular with those who want insulating and economical windows . PVC windows are available in a wide range of colors and can be customized to match the design of your home.
Aluminum is another popular material for double glazed windows due to its strength and durability. Aluminum windows are usually more expensive than PVC windows, but offer better thermal and sound insulation.
PVC carpentry for double glazed windows
The PVC joinery consists of a frame made of PVC profiles and sealed double glazing . This type of joinery provides excellent thermal and sound insulation and is easy to manufacture and maintain.
PVC profiles are made of polyvinyl chloride (PVC), a very durable and weather-resistant plastic polymer. These profiles are filled with rigid polyurethane foam to increase thermal insulation. The profile is designed to have drains to prevent water and mold build-up.
PVC windows are sealed with insulating glass consisting of two sheets of glass separated by a layer of air or inert gas. This design provides excellent thermal insulation, reducing heat loss from the home and helping to reduce energy bills. Double glazed windows also offer a significant reduction in outside noise, making them ideal for those living in busy or noisy areas.
Other material options for double glazed windows
Apart from PVC and aluminum joinery, there are other material options for double glazed windows, such as wood and fibreglass. These options are less used than the other two, but can be ideal for those who want a traditional look or for those who want maximum thermal and sound insulation.
The quality of thermopane windows
One of the most important features of double glazed windows is the glass they are equipped with. They provide thermal and sound insulation, ensuring thermal comfort and peace in the home. The quality of the double glazing is essential for the performance and durability of the windows.
An important factor to consider is the thickness of the windows. Thicker panes provide better insulation and reduce noise. However, it should be borne in mind that too much thickness can lead to too much weight of the glass, which can affect the handling of the windows.
Also, the type of glass used can make a significant difference in thermal and acoustic performance. Low-E glass windows are the most popular options as they reflect heat back into the home and reduce energy loss. Laminated glass windows are another popular option, especially used in areas with security risks.
Additional treatments to improve thermal and acoustic performance include anti-theft films, sun protection, hydrophobic treatments or anti-limescale treatments.

How is the thermal performance of double glazed windows measured?
To understand the thermal performance of double glazed windows, it is important to know two basic terms:
- Heat transfer coefficient (U) – measures the amount of heat that passes through the insulating glass. The lower the value of the coefficient, the better thermal insulation the thermal insulation windows offer. The U value is expressed in W/m²K.
- Solar factor (g) – measures how much solar energy can pass through the glass into the room. The higher the value of g, the more solar energy the windows allow to penetrate inside. The value of g is a dimensionless measure between 0 and 1.
Typically, the thermal performance of a double glazed window is indicated by a set of three numbers, such as 4-16-4. This set of numbers indicates the thickness of each pane and the space between them, as well as the U-value of the window.
For example, a set of 4-16-4 means that the windows are composed of two panes of 4 mm each, separated by a gap of 16 mm, and the U-value is 2.8 W/m²K.
The lower the U-value, the better the thermal performance of double glazed windows. Typically, the U-value of double glazed windows varies between 0.8 and 1.1 W/m²K.
Although the U coefficient is an important measure of thermal performance, it is also important to consider the solar factor when choosing double glazed windows, especially if you live in a warm climate.
