Great insulation – Improved heat retention is one of the main double glazing benefits.

One of the main benefits of double glazing is improved heat retention. A key function of a window or door is to keep the heat in and the cold out.

All double glazing units have an insulating layer of air trapped between the two panes of glass and this insulating layer helps your home retain up to 60% more heat than a traditional single glazed window. When every window and exterior door is replaced with a double glazed unit the effects in terms of heat retention become apparent very quickly.

During those hot summer months, they keep the extreme heat outside so the warmth does not become too much. Essentially, double glazing will help keep you home cool in the summer and warm in the winter.

Lower energy bills is definitely a huge benefit

It stands to reason that if your home is retaining the heat it produces there isn’t going to be a constant need to replace it. In other words, if you use gas to heat your home then your gas bill will fall, and if you use electric storage heaters then your electric bill will fall.

With the constant price increases being imposed by energy providers the savings you make on your utility bills over the first few years will often equal the price you pay for your double glazing.

Better noise reduction benefits both yourself and your neighbours.

Some people live in very noisy neighbourhoods, something that can be an annoyance, especially at nighttime.

Well, double glazing will help keep noise out and should reduce the frustrations around noisy neighbours. Some of the old-style windows can let even the smallest noises come through into your home which can make sleeping a real mission.

If you were to go down the double glazing route these little noises would no longer be a problem, and bigger noises would be toned down considerably. Also, on the flip side, with double glazed windows, you’ll be doing your bit for your neighbours as they would also help keep your noise from leaking out of your home, too!

Easier maintenance of your windows and doors

Once double glazed units are installed and sealed they require very little in the way of maintenance. You might need to wash them down occasionally for them to keep their new appearance but you won’t need to do any of the time-consuming jobs associated with single glazed windows.

So, you won’t need to sand the frames every year so they can be repainted, you won’t need to seal them against damp and rot, you won’t need to replace broken bits of frame or windowsill and you won’t need to climb a ladder every week to dry the frame after the window cleaner has been. In terms of maintenance, life is definitely easier with double glazing.

Double Glazing Benefits

Lower repair costs

You may think we have got this the wrong way round but we haven’t. The main repair associated with double glazing is a blown seal. This means that the seal keeping the insulating layer of air between the two sheets of glass develops a fault and as a result water creeps into the gap. Thankfully this is very easily fixed and can be done within a few hours for around £60-£80 in most cases.

Repairing a traditional single glazed window with a wooden frame, however, requires a skilled craftsman and there aren’t that many of them left in business. Because of this, if you do manage to find one in your local area who will come out and replace a broken window or repair a damaged frame it will often cost you a lot more than having a similar sized double glazed unit repaired.

Adds value to your home

It’s easy to see that professionally fitted double glazing looks much better in your home than tired old traditional wooden window frames and single glazed windows. Double glazing will also add value to your property as it will score better energy efficiency marks, sometime adding on as much as 10% to the value of home!

Every residential property that goes on the market in the UK has to undergo a series of tests to determine how energy efficient it is and how much carbon dioxide it releases into the atmosphere. The rating it gets is very like the rating you see on domestic appliances. A rating of A to C means your property is very energy efficient and this will add to the price you can ask for it. A rating of D or E means it is less efficient and this might make it difficult to sell. Anything less than an E rating (which is what single glazed windows would produce) will make your home virtually impossible to sell, even at a reduced price.

Better security, are there security benefits of double glazing?

As you can see from the points above, double glazing can provide the home with a wide range of benefits. From increased energy efficiency to reduced noise and aesthetic improvements, new double glazing can enhance your home in many different ways.

However, one of the things that many people do not realise is that double glazing can also significantly enhance the security of the home, which means greater peace of mind. Most of us go to great lengths to make our homes as secure as possible, investing in everything from costly security alarms to CCTV. Quality double glazed units can add an additional and vital layer of security.

How double glazing can enhance the security of your home

There are a number of ways in which double glazed units can enhance the security of your home. Remember, your doors and windows are the main points of entry for intruders so you need to opt for high-quality units that conform to British standards in order to enjoy the optimum security benefits that double glazing can offer.

Some of the security benefits of double glazing

Secure locks: Most high quality double glazed units these days will come with sturdy locks to help keep intruders out of your home. Of course, you have to make sure you are responsible about locking your windows and keeping the key somewhere safe but the ability to securely lock your windows will give you added protection and peace of mind.

Tougher glass: While some intruders may try to be subtle about breaking into your home, others will not think twice about simply smashing glass in order to gain entry to your home. Vandals can also cause damage to your home in this way, even if they do not plan to gain entry to the property. The tougher glass you get with high quality double glazed units can make it more difficult for vandals and thieves to get into your home by smashing your windows.

Tougher frames: If you opt for frames such as UPVC you can benefit from increased strength and durability compared to older, wooden frames. For a thief, an old wooden window or door frame is a real treat, as it can be easily forced to gain entry. Tougher material such as UPVC makes life more difficult for the average thief or vandal, which in turn makes your property more secure.

It is also worth remembering that high quality double glazed units will not only improve security levels in your home but can also help to reduce costs. This is because the enhanced security that comes with double glazing can reduce the risk of break-ins and vandalism, which is something that many insurance companies will take into consideration when you take out home insurance. This decreased risk can, therefore, be reflected in the premiums you pay for your home insurance coverage, enabling you to cut the cost of protecting your home as well as increasing security.


So, as you can see there are several key benefits of double glazing. Double glazing is definitely worth the investment and as there are grants available to help with the costs (see double glazing grants) there is no reason why you can’t have it installed before the next cold spell hits.

  1. As a Window Repair company, I find that a lot of people who have blown units are surprised that it is a relatively low cost to have this repaired, rather than replaced!
    Excellent article, and very useful for everyone to read.

  2. Thanks for posting on double glazed windows. Windows has an immense impact on our house because it provides warmth from the sun. It’ll make our house comfortable and save money.

  3. All of the above are great benefits BUT … only if the windows, doors or conservatories have been installed correctly. Do your homework, even big companies employ cowboys. A lot of firms have self employed installers that rush the jobs for more money. Be vigilant when choosing a reputable installer. Choosing a local firm with employed fitters is often a good choice.
