Double-glazed window installation is becoming one of the most popular ways to save energy, money and reduce outside noise. As a solution for hot and cold climates, architects and designers are recommending double glazing for energy efficient buildings. With double glazing, your windows are thicker and reduce energy consumption. Additionally, the fact that all new homes need to meet the 7-star energy efficiency standards, has seen an increase in double-glazed window installation. We explain everything you need to know about double glazing, its benefits and disadvantages, and how to install double-glazed windows.
A window that has two pieces of glass instead of one is known as double glazing. The two layers of glass set in a window frame have a small insulating gap in between them which acts as a divider between the inside and the outside glass. The gap is filled with a low-conductivity gas, which works as an insulating barrier and reduces heat transfer. This means when it is hot outside, the heat does not transfer as easily to the inside of the home. When it is cold outside, the heat inside the home is trapped and less likely to escape.
Double-glazed windows can be installed in various window frames but are best suited to uPVC frames. That is because uPVC provides almost identical benefits to double-glazing. uPVC is unplasticised polyvinyl chloride, a type of hard plastic often used as a substitute for painted windows and the preferred material when installing double-glazed windows. It has a proven increase in insulation performance, directly influencing your window installation’s thermal and sound-reduction properties. This results in a superior alternative to typical metal or timber frames, which instead conduct heat and counteract the efficiency of a double-glazed solution. Furthermore, uPVC remains consistent with the eco-friendly benefits offered by double glazing, allowing homeowners confidence in the sustainability of their window choice.
Homeowners and builders are finding double-glazing has a plethora of benefits that reach beyond environment and energy savings. Listed below are the many advantages of installing double-glazed windows.
While the benefits far outweigh any negative features, there are still a few disadvantages to be aware of when installing double-glazed windows. Listed below are some cons of double-glazed windows.
Double-glazed windows can be installed in a new building construction or replaced in an existing home. For a new home, you will likely have a professional builder. However, you can hire a professional or DIY in an existing home where the windows are being replaced. It is important to remember that to work efficiently, double-glazed windows need to be installed the right way. That usually means with professional installation unless you have the skills to install windows yourself. We look at the two options for installing double-glazed windows – professional installation and DIY.
Having double-glazed windows professionally installed is the best way to ensure the job is carried out properly. Professional installers have years of experience installing windows and understand it is not just about putting a window in a wall.

Professional installers understand the problems that can occur when installing double-glazed windows and plan accordingly. They take into account local building regulations and codes and make sure that installation complies with every legal requirement.
