What is secondary glazing?

Secondary glazing is a window treatment that involves installing an additional second glass pane on an existing window’s interior. This additional layer of glass creates an insulating barrier that can help reduce heat loss and noise pollution and even enhance the security of your property.

Unlike double glazing, which involves the installation of a completely new window unit, secondary glazing can be applied to existing windows without requiring major renovations or replacement. This makes it a cost-effective preference for homeowners who want to improve their homes’ energy efficiency and comfort without breaking the bank.

So why do people choose to have secondary glazing? There are several reasons why homeowners might opt for this type of window treatment.

• Energy Efficiency: Secondary glazing can help reduce heat loss, leading to lower energy bills and more comfortable living space. This is particularly valuable for homeowners with older, single-pane windows that are less efficient at insulating the home.
• Noise Reduction: Secondary glazing can also help reduce noise pollution from outside sources, such as traffic or construction. This is especially critical for homeowners who live in busy urban areas or near noisy roads.
• Security: Secondary glazing can enhance the security of your home by providing an additional layer of protection against forced entry. This is because the second pane of glass makes it more difficult for intruders to break through the window.
• Preservation: Secondary glazing can help preserve the original windows in older homes, which can be essential for maintaining the property’s architectural integrity.
• Versatility: Secondary glazing can be applied to a wide range of window types and sizes, making it a versatile option for homeowners.

So, whether you’re looking to reduce heat loss and noise pollution or enhance the overall value of your property, secondary glazing is a great option to consider.

How is secondary glazing installed?

Installing secondary glazing is a relatively straightforward process that involves fitting a second pane of glass to the interior of an existing window. While it is possible to install secondary glazing yourself, it’s recommended that you seek the help of a professional installer to ensure that the job is done safely and correctly.

Here’s a closer look at the installation process for secondary glazing:

1. Measure the window: Before installing secondary glazing, you’ll need to measure the dimensions of the existing window to ensure that the secondary pane will fit correctly. Please be aware that secondary glazing comes in various types, and the measurement dimensions required will vary depending on the type of fixing used for the secondary glazing pane.
2. Order the secondary glazing: Once you have the measurements, you can order the secondary glazing from a reputable supplier. They will create a custom-made glass pane that fits your window’s dimensions.
3. Prepare the window: To prepare the window for installation, you’ll need to clean the surface of the existing window and remove any debris or obstructions.
4. Fit the secondary glazing: The next step is to fit the secondary glass pane to the existing window’s interior. This involves attaching the secondary pane to the window frame using either magnetic strips or a track system.
5. Seal the edges: To ensure that the secondary glazing is air-tight, you’ll need to seal the edges of the secondary pane using either silicone sealant or draught-proofing strips.

It’s worth noting that while it is achievable to install secondary glazing yourself, it can be a time-consuming and challenging process. Suppose you’re not confident in your DIY skills. In that case, it’s recommended that you seek the help of a professional installer, and we are here to help with that.

Remember, secondary glazing, including sash, casement, and tilt-and-turn windows, can be installed on almost any window type. This means that homeowners can appreciate the benefits of secondary glazing without replacing their existing windows.

How much does secondary window glazing cost?

If you’re considering installing secondary glazing, one of the biggest questions on your mind is how much it will cost. Secondary glazing costs can vary depending on a range of factors, including the size of the window, the type of glazing, and the complexity of the installation process.

Here’s a breakdown of the factors that can affect the cost of secondary glazing:

• Window size: The larger the window, the more expensive the secondary glazing is likely to be.
• Type of glazing: Various secondary glazing types, including acoustic and thermal options, are available. The type of glazing you choose will impact the cost.
• The complexity of installation: If the installation process is complicated, for example, if you have an irregularly shaped window, this will impact the installation cost.

As a rough guide, you can expect to pay around £300-£500 for 1m x 1m for secondary glazing. However, it’s essential to remember that this is just an estimate and that the cost can vary depending on your circumstances.

Types of secondary glazing units

Several types of secondary glazing units are available, each with its unique set of benefits. We’ll look at some of the most common types of secondary glazing units.

Magnetic

Hinged

Fixed

Lift-Out

Sliding

1. Magnetic Secondary Glazing: This type of secondary glazing unit comprises two acrylic panels with magnetic strips around the edge. The panels can be easily removed for cleaning or to allow for ventilation. Magnetic secondary glazing is an excellent option for those who want a quick and easy installation process.
2. Hinged Secondary Glazing: Hinged secondary glazing units are attached to the existing window frame with hinges. They can be opened and closed like a window, allowing for easy access to the primary window. Hinged secondary glazing is a good option for those who want to maintain the appearance of their existing windows.
3. Fixed Secondary Glazing: Fixed secondary glazing units are attached to the existing window frame and cannot be opened. They are a good solution for homeowners who wish to increase their windows’ thermal and acoustic efficiency without losing aesthetics.
4. Lift-Out Secondary Glazing: Lift-out secondary glazing units are similar to hinged secondary glazing units, but they can be easily lifted out of the frame for cleaning or to allow for ventilation. This type of secondary glazing is a good option for those who want flexibility in their window design.
5. Sliding Secondary Glazing: Sliding secondary glazing units consist of two or more panels that slide horizontally or vertically within a track. They are an incredible choice for those who want to maintain the appearance of their existing windows while also improving their thermal and acoustic performance.

When choosing the right type of secondary glazing for your home, there are several factors to consider, including your budget, the style of your home, and your personal preferences. 

Magnetic secondary glazing is generally the most affordable and easiest to install. In contrast, hinged and lift-out secondary glazing units are more expensive but offer greater flexibility. Fixed and sliding secondary glazing units are the most expensive but also offer the most significant improvements in thermal and acoustic performance.

Advantages of secondary glazing

Secondary glazing effectively improves your home’s insulation without the cost and hassle of replacing your existing windows. Here are some advantages of secondary glazing:

Economic benefits

One of the most significant advantages of secondary glazing is its potential energy savings. Adding an extra layer of insulation to your windows can significantly reduce the amount of heat lost through them, saving you money on your energy bills.

Better sound insulation

It also helps to reduce the amount of noise that enters your home. This is particularly useful if you live in a noisy area, near a busy road, or under a flight path.

Benefits for those in heritage properties/listed buildings

Secondary glazing is an excellent option for those living in heritage properties and listed buildings, where double glazing is either not allowed or impractical. Secondary glazing can help retain the character and appearance of these buildings while still providing improved insulation and noise reduction.

Double glazing comparison

While double glazing is also an effective way to improve your home’s insulation, it can be more expensive and less suitable for heritage properties. Secondary glazing is often a more cost-effective and practical option for those looking to improve the energy efficiency of their home.

Disadvantages of secondary glazing

While there are numerous benefits to installing secondary glazing in your home or business, there are also some potential downsides to consider. These include:

Reduced aesthetics 

One of the main disadvantages of secondary glazing is that it can affect the look of a window. Although modern secondary glazing units have been designed to be as unobtrusive as possible, some people may detract from the overall appearance of their windows. Additionally, secondary glazing can make cleaning the windows more difficult. 

Reduced natural light 

Similar to the above, adding an extra layer of glass to your windows can also reduce the amount of natural light coming into your space. This may not be perfect if you have a room already quite dark or value natural light in your living or working spaces.

Installation challenges 

While installing secondary glazing is generally easier than double glazing, it can still be challenging. The installation process typically involves fitting the secondary glazing units inside the window frame, which can require some specialist knowledge and tools. 

Additionally, suppose the window frame is old or damaged. In that case, it may need to be repaired or replaced before secondary glazing can be installed. 

Reduced effectiveness 

Although secondary glazing can offer significant benefits, it is not as effective as double glazing when it comes to insulating a property. This is because there is still an air gap between the primary window and the secondary glazing unit, which means that some heat can still be lost. 

Cost 

While secondary glazing is generally less expensive than double glazing and triple glazing, it can still be a significant investment. The cost will depend on factors such as the size of the windows, the type of secondary glazing units chosen, and the complexity of the installation. For some people, the cost of secondary glazing may be prohibitive. 

Despite these potential disadvantages, secondary glazing can still be a valuable investment for many homeowners. As with any home improvement project, weighing up the pros and cons and making an informed decision based on individual needs and circumstances is important.

Can I install secondary glazing myself?

When considering secondary glazing for your home, it’s natural to wonder if you can install it yourself. While saving money by taking on the installation yourself may be tempting, it’s important to consider the potential pitfalls.

First and foremost, it’s recommended to have a professional install secondary glazing to ensure proper installation and avoid any potential damage to your windows or property. A professional installation can also ensure the secondary glazing is fitted correctly to provide optimal insulation and noise reduction benefits.

Attempting to install secondary glazing yourself can lead to issues such as gaps in the seal, improper fitting, or even damage to your existing windows. These issues can compromise the effectiveness of the secondary glazing and potentially cost more in the long run to repair.

While it may seem simple, it requires precision and skill to ensure the best results. By enlisting the help of a professional, you can have peace of mind knowing that your secondary glazing is installed correctly and will provide the benefits you seek.

How to find the best secondary glazing company near me

Finding the right company to install your secondary glazing or perfect window styles can be daunting. Here are some hints to help you find the best secondary glazing company near you:

• Look for local companies: Choosing a local company can offer several benefits, including faster response times, more personalised service, and a better understanding of local building regulations.
• Check reviews: Check online reviews on sites like Google, Trustpilot, and Yelp to see what other customers have to say about their experiences with the company. Pay attention to both positive and negative reviews to get a balanced view.
• Ask for recommendations: Word of mouth is a powerful tool, so ask friends, family, and colleagues if they know of any reputable secondary glazing companies.
• Check credentials: Make sure the firm you choose is registered with professional organisations, such as the Glass and Glazing Federation, and has the necessary certifications to install secondary glazing.
