DOUBLE GLAZING VS SECONDARY GLAZING
When it comes to improving the energy efficiency of your home, there are a few different options available to you. Double glazing and secondary glazing are two of the most popular methods used to improve a home’s thermal and acoustic performance. So which is better?
What is Double Glazing?
What is Secondary Glazing
Secondary glazing is a type of window that consists of an additional pane of glass added to an existing window. Like double glazing, this extra pane of glass helps to insulate the home and improve its energy efficiency and block out noise.
Which is Better?
There are a few key differences between the two types of windows that you should consider before making a decision.
Double glazing is generally more thermally efficient than secondary glazing. This is because the two panes of glass in a double-glazed window are separated by a much larger air gap than the pane of glass in a secondary-glazed window. This allows for less heat transfer and makes double-glazed windows better at insulating your home.
Both double glazing and secondary glazing can help to reduce noise levels in your home. However, there is a misconception on the internet that secondary glazing is better at noise reduction than double glazing. In reality, secondary glazing doesn’t come close to the noise-reducing capabilities of a fully sealed double glazed unit.
Double glazing is typically more expensive than secondary glazing. This is because you are replacing the entire window with a double glazed unit – compared with secondary glazing which just involves adding an additional pane of glass to an existing window.
One of the biggest advantages of secondary glazing is that it can be installed without having to replace your existing windows. This makes it a much less disruptive and cheaper option if you’re looking to improve the energy efficiency of your home. Double glazing, on the other hand, requires the installation of new windows – which can be a much more disruptive process.
Which One Looks Better
Double glazing looks much better than secondary glazing and have a more streamlined look which can be made to match the aesthetic of your home perfectly. Secondary-glazed windows, on the other hand, can look quite bulky and out of place, you also get the unavoidable “double reflection” effect when viewing the window glass at certain angles.
Ease of Use
Double glazing operates just like any other window. You can open and close them with no fuss, and they’re easy to clean. Secondary glazing, however, can be more difficult to use. The additional pane of glass can make it clumsy to open and close your window, and cleaning the windows can be a bit of a pain.
The lifespan of a double-glazed window is typically between 20-35 years. The lifespan of secondary glazing will depend largely on the quality of the installation and the materials used. However, it is not uncommon for secondary glazing to last 10 years or more.
