Science Behind Double-Glazed Windows

Gone are the days when home construction was just used to be about walls and rooms. With the invention of automation systems and smart technologies, homeowners are focusing on the benefits like energy efficiency, high security, aesthetics and functionality.

One of the aspects where you can make small changes and get a significant impact is by having double-glazed windows. Insulating your windows or choosing high-quality glass will significantly improve the inside temperature. Choosing such materials will help you rely less on artificial cooling systems. 

In this blog, you will understand the meaning of double windows and how choosing them is beneficial to you. 

Understanding the meaning

These windows are also called Insulated Glass Units (IGUs). As the name suggests, these windows consist of two glass panes that are separated by a gap. The gap is filled with air or inert gas such as argon. 

The whole structure is then sealed to form a single unit and is made to install like a regular window. The windows that are designed with double-glazed glass offer you thermal and acoustic benefits. 

The science behind these windows:

1. Offer thermal insulation
   If you understand the concept of thermal conductivity, then you can learn the science behind these windows. We all know that glass is a good conductor of heat, so having a single glass window will transfer heat from outside and increase the inside temperature.
   
   
   If it’s too hot outside, then your home temperature increases, making your living uncomfortable. However, if the window is double-glazed, it acts like a barrier - the gap of air acts as a separator.
   
   
   The air in the gap acts as a good conductor of heat, which means it slows down the transfer of thermal energy. For better insulation, inert gases are used as they reduce heat loss in winter and heat gain in summer. 
   
   
2. Decrease in heat transfer
   When you talk about reduction in heat transfer, you have to talk about conduction, convection and radiation. The conduction is reduced because of the air-filled gap between the glass panes. It enables air circulation and thus minimises convection currents. If you choose these windows with a low-emissivity coating, the heat is reflected into the house during winter and reflected out during summer. This is the science that goes through these windows that helps in making your home energy-efficient. 
   
   
3. Blocking loud noises
   Another great benefit of these windows is that they block loud noises from the outside. The soundproofing benefit is the other reason why these windows are so popular. As the window contains two layers of glass that are separated by a layer of gas or air, it acts as an obstruction to sound waves. It absorbs sound waves and vibrations and keeps the noise outside and making your interiors perfect, especially when your home is in a busy urban area. 
   
   
4. Condensation control
   The windows become misty when hot and moist air touches the cool surfaces of the window glass. The issue won’t be there if it’s a double-glazed window. As the inner pane’s temperature is closer to room temperature (because of the air between the gaps), it reduces the chances of condensation that forms inside the house. 

Points to be noted about double-glazed entrances:

• You can make your building more energy-efficient and see a significant dip in your power bills. You can rely less on air heaters and air conditioners. 
• If every window is insulated in your home, then you can live comfortably and see less usage of air conditioners. 
• No outside noise to disturb your private life inside your home.  
• Lower carbon emissions and reduce energy consumption in your building.
• You have a nice, stable temperature inside your home all year round.
• You can have a drier and healthier living space due to less condensation.

Final Thoughts

Understanding the working of double-glazed means you know the simple science behind making your home energy-efficient. Making smart and eco-friendly choices in the construction of your home will help you walk towards a greener environment. With a double-glazed option, you can live comfortably with fewer power bills and enjoy a natural temperature inside your home.
