10 Benefits of Modern Secondary Glazing

10 Benefits of Modern Secondary Glazing

If your home gets icy-cold over winter or lets in lots of external noise, it can become less of a joy to live in. With the current sharp rise in energy costs, you might be feeling reluctant to even turn the heating on – which can lead to damp developing within your home. Fortunately, there’s a solution – modern secondary glazing!

Unlike older forms of glazing, modern secondary glazing offers unique benefits to create a truly warm and efficient home. So, what are the benefits of modern secondary glazing? Let’s take a look at them now…

Benefits for your home

Modern secondary glazing can make a real impact on your home – and not just in the ways you might expect…

Thermal insulation

Arguably the most well-known benefit of modern secondary glazing is thermal insulation. When it comes to energy efficiency, secondary glazing can improve performance by more than 60%. That can take a huge 10-15% off your energy bills!

So, how does it work? With a sealed secondary panel, you create a gap between your home and the outside world that is 100% airtight. The bigger the gap, the better the insulation. If you’d like to improve your thermal insulation even further, when choosing your glass, go for Low E glazing (also known as Pilkington K). This invisible coating is proven to increase the insulation performance of the glass by 65%.


Modern secondary glazing doesn’t just keep the warm in, it also keeps outside noise out. If your neighbours keep you up at night, it can affect everything from your sleep to your work output.

Installing secondary glazing places an additional barrier between your home and unwanted outside noise. You can maximise these effects by increasing the gap, as well as choosing a specialist acoustic glass.

Security and safety

Keeping your home secure is a priority for any homeowner, but flimsy single-glazed windows often won’t do the job. As they’re easy to break, this makes them a point of weakness for most properties.

Modern secondary glazing adds a secondary protective layer to your window, making it harder for intruders to gain access. Plus, we offer secure 4mm toughened glass as standard – or upgrade to laminate for a shatterproof option.

Reduces condensation

Nobody likes the sight of mould and condensation – nor the effects on their lungs. Unfortunately, thin single-glazed windows often have a cold interior surface, and this can draw in moisture, allowing condensation to form.

That’s where modern secondary glazing comes in. By providing an insulating seal between the panels of glass, the interior glass can be prevented from becoming too cold. This helps to eliminate the cause of condensation at its root.

Retaining character

If you live in a period property, chances are you love it for its unique character. The traditional windows of your home are likely to be part of its charm, so getting rid of them would downgrade the look and feel of the property.

But what if you’re feeling the winter chill through traditional single-glazed windows? Modern secondary glazing provides the perfect solution, as you can keep your original windows and gain the thermal and acoustic benefits of a secondary pane of glass.

Extra benefits for you

Aside from benefiting your home, there are plenty of additional advantages to modern secondary glazing to consider…

Cuts down your bills

As it keeps your home toasty through the winter months, you’ll be improving your energy efficiency. That means cutting a huge chunk out of your bills each month. Plus, the insulating benefits of modern secondary glazing are equally successful at keeping homes cool. So, you’ll find that when summer comes around, you won’t be rushing to the aircon all the time.

Meets listed building requirements

For many listed properties, you won’t be able to install double glazing. But that doesn’t have to mean struggling through the cold in winter months. One of the major benefits of modern secondary glazing is that it’s very subtle and doesn’t require the removal of original windows.

Although it’s always important to check with your local planning department first, secondary glazing can often be a suitable alternative for listed buildings.

Easy to install

No matter how much you need that extra insulation, the thought of installing it can be off-putting. So, you’ll be pleased to know that modern secondary glazing is incredibly easy to install. In fact, there’s even the option to tackle it yourself! Our DIY secondary glazing kits come ready to install – so there’s no need for disruption in your home.

Kind to the environment

Worried about your carbon footprint? You don’t have to be with modern secondary glazing. Installing new uPVC windows contributes to manufacturing processes that can impact on the environment through the release of chemicals. Disposing of old windows can also add to landfills.

On the other hand, secondary glazing simply adds an extra pane of glass to your current windows, so there’s no need to dispose of anything.

Improvement over other forms of glazing

If you’ve tried double glazing before and didn’t notice much of a difference – or hated the disruption of the installation – you might have written off secondary glazing too. What you might not realise is that modern secondary glazing is a huge step above other glazing options.

For one thing, you won’t have the added costs of removing original windows, nor the unsightly aesthetics. Secondary glazing is also more effective at draught reduction and soundproofing.
