There are a number of features to consider when it comes to selecting the type of windows for your property. From aesthetics to energy efficiency, windows impact our homes in all manner of ways. This is especially true when considering the current cost-of-living crisis, in which the price of heating homes is growing out of control.
As a result, if your windows are in need of replacement, you want to ensure you’re making the right decision. It’s no longer just about double and triple glazing; there are numerous available glazing options for energy-efficient windows.
Discover more about the various glazing specifications below.
What Is Double Glazing?
As the name suggests, a double-glazed window is one that contains two panes of glass. That said, the number one feature of a double-glazed window is the insulated glass unit (IGU), which sits in the window’s frame. This IGU consists of two glass sheets that are separated by a spacer bar; this creates an air gap that’s filled with an insulating gas.
The purpose of double glazing is to achieve thermal insulation, meaning heat gets trapped inside, and cold air isn’t permitted to enter from outside. The energy efficiency of double glazing is so great that all replacement windows are legally required to be a minimum double-glazed C rated.
What Is Triple Glazing?
It probably goes without saying that triple-glazed windows contain three panes of glass, which results in enhanced energy efficiency. As with double-glazed windows, triple-glazed windows have an IGU that sits in the frame. Instead of two sheets, however, this consists of three panes separated by spacer bars. As a result, two air gaps are created, which are filled with insulating gases.
Due to there being two air gaps, this improves the thermal insulation even further, making triple glazing a popular option for replacement windows.
Is Triple Glazing Worth It?
In short, triple glazing is worth it. A significant amount of heat loss in homes takes place through windows; since triple glazing is the better insulator, this means more heat is retained, and more cold air is staved off. Similarly, condensation is less likely to occur with triple-glazed windows.
From a safety perspective, three panes of glass are harder to break than two, acting as a deterrent to break-ins. Meanwhile, triple glazing acts as an additional barrier to noise, meaning you won’t be as disturbed by outdoor noises, and you’ll have more privacy for yourself.
Of course, triple glazing costs more than double upfront; however, the money that gets knocked off your energy bills makes triple-glazed windows the more cost-effective option.
