Double Glazing Vs Secondary Glazing
For many households, installing new windows is a step towards lower energy bills and a better-insulated home, either to keep it warmer during the cooler months, or to keep the air conditioning from escaping during the hot summer months. Homeowners may decide it’s time to replace their windows when they notice their current ones are damaged, warped, or broken beyond repair – decaying window frames and leaky windows are a good sign that it’s time to update. Want to know whether Double or Triple glazing is best, read here. Maybe reducing energy bills is a main priority, which can be achieved with new windows as well, or maybe your home just needs a bit of a makeover and an upgrade.
Replacing the windows in your home can be an expensive endeavour, especially when there are a lot of windows that need replacing. It’s important to figure out what kind of needs you need satisfying for your home when it comes to new windows, because it will help determine what kind of windows to purchase. The investment is worth it though, because new windows can boost your home’s value and add major curb appeal.
What kind of windows should you invest in?
Window technology has progressed significantly over the last few decades, and if you haven’t updated your windows in a long time, or perhaps even since you moved in, you may be surprised at how much of a difference a new set of windows can make. Your home can be much more energy-efficient, and you can save a good amount of money each month of your heating or hydro bills.
Some other key aspects to consider when shopping for new windows are the kinds of abuse they will take in terms of normal wear and tear caused by factors like the weather. Depending on the part of the country that you live in, your windows could need to withstand heavy rains, strong winds, freezing rain, hail, ice, and direct sun. Over time, these can take their toll on your windows, so when purchasing new ones, it’s important to think about how these weather patterns will affect your new windows and how they will function.
When it comes time to decide which type of window glass you want, it can be overwhelming because there are so many options to choose from. The two most widely installed types of windowpane installations are double glazed windows and secondary glazed windows. If you aren’t sure which one is right for you, here’s a breakdown of each type, their benefits, their drawbacks, and a comparison between the two.
Double glazed windows
Double glazed windows are made up of two panes of glass, which are separated by a layer of insulation – usually air or gas. This extra layer of insulation is great for blocking outside noise and keeping your home warmer. Double glazing with gas (usually argon) between the panes of glass is a better insulator than air or windows with no extra layer at all. Furthermore, you can get double glazed windows that use low-emissivity glass (also known as Low-E glass), which has a reflective coating on it. The reflective coating helps bounce any sunlight back into a home, helping warm it up even more.
When fitting double glazed windows into your home, you will need entirely new units fitted, which does raise the cost. They also need to be installed by professionals, but the process is quick once the windows are made for your home. The people installing your new windows can install roughly three per day, so if you’re fitting your entire home with double glazing units, the entire installation can be finished in under a week.
Secondary glazed windows
Secondary glazing is a process that involves installing additional glazing to the inside of an already-existing single glazed window. It’s effectively adding another layer of insulating material to an existing window. Often, secondary glazing is added to a window as a temporary fix, but on occasion, it can be permanent.
The process of installing secondary glazing is quick and can even be done yourself if you have the proper know-how. An internal secondary window is installed on the room side of your existing window that is fully independent of the existing window. The secondary window is a single glazed window in its own frame, fitted on the inside of your home and sealed around the edges. You can install a variety of window styles depending on how you want it to open, but the most common are horizontal or vertical sliders with separate handles on them.
Because it’s more a process of installing a separate secondary window pane rather than installing a whole new window, secondary glazing is a more cost-effective way to add insulation to your home and to reduce the amount of noise from outside. The process doesn’t involve completely removing and refitting new windows and frames, so it’s a cheaper alternative than double glazing.
While double glazed windows can be pricier than secondary glazed windows, they will provide better insulation for your home. Despite the process being more complex and lengthy for double glazing, the installation is quick and the end results are worth it – your windows will last longer, retain more heat, and block out more sound from the outside. They’re also less difficult to open and close, since secondary glazed windows often slide to the side and can get stuck easier than double glazed windows that most often open up.
For those who are a bit nit-picky about dirty windows, good news: double glazing is also easier to clean than secondary glazing. You only need to clean the inside and outside of your double glazed window panes, whereas secondary glazing requires you to clean the inside and outside of four window panes, and reaching and cleaning the panes backing onto cavity are difficult.
Take a look at your home and what kind of needs you require for your new windows. If you’re after cheaper monthly energy bills, better insulation, and higher grade and long-lasting windows, double glazing is the way to go.
