Double Glazed Windows – Pros and Cons
Updated: Jan 3
Cold in winter and hot in summer – single glazing is definitely a pass? And for all the good reasons.
As we increasingly look forward to making our homes not only cool in summer and warm in winter, but also aesthetically pleasing and energy efficient, thoughts turn towards the all-mighty double glazed windows as a simple way to achieve the lifestyle you want.
In recent years, double-glazed windows, which are also called as insulated windows, have become a popular choice for most premium urban residences. These modern contemporary windows contain panes of glass and are available framed in materials like aluminium and uPVC. The space between the two glass panels that are filled with inert gases like xenon, krypton or argon is there to form an airtight seal and a tough insulating barrier between the interior and exterior structure of the building.
If you are planning to make your home energy efficient as 10% of heat is lost in our homes through doors and windows, so upgrading to double glazed windows is a legit no-brainer. Besides that, there are the other ins and outs of installing double-glazed windows in your home. Our guide will help you decide whether these types of windows are the way to go or not.
Pros of double glazed windows
Let’s begin with a rundown of all the pros that come with installing double glazed windows.
Reduced Energy Bills
Double glazed windows are a treat for both the wallet and environment, as they can significantly reduce the loss of heat in winter and eventually, your electricity bill too (think of all the energy you’ll save by not excessively using the heater).
In the summertime, the insulating gap between the windows helps to reduce the amount of heat entering the home. This means that you do not have to tune your AC to high settings (more energy consumption, in summers too).
By replacing frames and leaky windows with new double glazed ones, you will also reduce the amount of air exchange with the outdoors. This will reduce your home’s carbon footprint. With double glazing, you not only save money but also do a favour to the planet.
Reduced Noise Pollution
Neighbourhood noises, kids playing, traffic, – double glazed windows have added protection against all the noise pollution. Particularly efficient window systems can offer a noise reduction of up to 35 decibels.
Double glazed windows also save you from listening to the rattle of panes on windy days, their more solid construction remains intact.
Single glazed windows are extremely vulnerable to break-ins as they are very easy to penetrate. However, the construction and glazing of double glazed windows are much sturdier.
Make sure not to neglect any smaller windows that burglars can hone in on when casing your house. You can also choose to level up your security by selecting a more toughened or laminated glass, which is un-smash-able.
Single glazed windows that have lived their expected life are nobody’s idea of an attractive house feature. You can fancy your home a facelift with modern, stylish double glazed windows. They come in a variety of frame styles, from contemporary blacks and greys to classic whites.
All of this helps to add more to the curb appeal and also increases the value of your home.
The insulating layer of trapped gas in the double glazed window panes prevents the air in your rooms and walls from coming in contact with the cold outer pane. This helps in preventing condensation, making your home more pleasant and healthy.
Cons of double glazed windows
If all these pros are making you want to rush out for quotes, BEHOLD! There’s are some cons to it as well, which are worth considering.
High Initial Cost
The initial outlay for double glazing is higher than for single glazing. This is because you are paying for two panes of glass instead of one, and the added complexity of the frames to consider and the way they are engineered to keep up with the insulating gap is there too.
Hard to Repair
Double glazed windows can be susceptible to concerns regarding the air gap.
If it’s breached and more moist air is allowed to enter, you can develop condensation issues. This will also decrease the sound-absorbing and insulating qualities of the windows.
If this happens, double glazed windows are very hard to repair. The only viable option left then would be replacing the window. Depending on the design and size of the window, this could easily become a costly repair.
Doesn’t Suit All Homes
For modern, contemporary homes, double glazed windows may model for the aesthetic quite well. But in traditional homes, their charm gets lost in the sleek double glazed frames.
However, there are ways around this, like installing wooden framed double glazing, or windows that are made to smoothly blend in with traditional curb appeal of old building styles.
Upgrading to double glazed windows is indeed a great way to increase your home’s value, energy efficiency, and battle with common issues like condensation. But still, it’s a significant investment, and the overall aesthetics of the home cannot be ignored. Weigh up the points we listed above to see whether this investment is for you or not.
