Secondary Glazing Cost

[toc]

Many people always think that double glazing their windows is the best option. However, secondary glazing works just as well and is lower in cost.

Secondary glazing has many of the benefits that double glazing offers, but without the higher cost. This allows you to save money on updating your home. It increases energy efficiency and helps you to reduce noise that enters through the windows.

If you’ve been planning on having double glazing on your windows and you would like to reduce your costs, you can ask a qualified glazing expert to come to your home and give you a free quote.

The specialist can give you a free quote for both secondary glazing and double glazing, so you can make your mind up after seeing the difference in the prices.

There are different types of secondary windows that you can have fitted in your home, from fixed glazing to sliding secondary glazing options. The cost of fixed secondary glazing is the cheapest choice, with sliding secondary glazing being on the more expensive end of the cost scale.

The good news is that secondary glazing offers people a solution, reducing the external noise that enters their home. It makes their property more energy-efficient to help lower heating bills in the long-term, without having to pay the double glazing cost.

The cost of secondary glazing is different for each home, and it will depend on a few factors, but it can cost from around £300 to £400 for each window.

Factors That Will Alter The Price of Secondary Glazing

The cost of secondary glazing differs for each property. It will be based upon various factors, such as how large your windows are and the design style you choose.

Size of the Window

Installing secondary windows to a regular terrace property in the UK will generally cost less than installing secondary glazing to a listed building, as many of these windows are normally larger size-wise.

Window sizes vary for each property. Your glazing professional will be able to measure your windows and provide you with a free quote based on your property’s specifications.

Windows that are larger size-wise will require more glass to ensure the secondary glazing will fit all the windows in your property. Depending on the type of glass that you select, this can also add additional costs.

For example, noise reduction glass will cost more than a standard piece of glass. However, if you live in an area that is quite noisy, it may be worth spending extra on adding noise reduction glass to your existing window.

Design Style of the Secondary Glazing

The style of the secondary glazing will have a great impact on the overall cost.

If you want to go for the lowest priced secondary glazing, then a fixed style is the cheapest. The main issue with this one is you won’t be able to open the window and let air in.

In terms of costs, the middle of the range is the best type of secondary glazing. However, it’s not so good for the summer, when it’s too hot.

If you’re happy to spend a bit more money, then a hinged or sliding secondary glazing is a good choice, too, as it will allow you to open the windows and let in fresh air when you need it.

What Does Secondary Glazing Mean?

Opening a window

Secondary glazing isn’t always that well-known, but it’s a good choice if you’re looking for an affordable solution to insulate your home.

This is how it works:

Separate windows sit within the window frame of your existing windows. This forms secondary double glazing in that particular window. So it’s similar to double glazing in the sense that there are now two panes of glass that sit within the window frame to block external noise and provide more energy efficiency.

If your window already has double glazing, installing this extra layer would equate to triple glazed windows. Some properties may benefit from this if they live in an extremely loud environment.

The secondary glazing generally has a thin frame, which is normally made using aluminium.

Secondary glazing is ideal for listed buildings, as it can be hard to gain planning permission to install double glazing. You’ll find this on many listed buildings – it’s a way to insulate without going against double glazing that may be prohibited.

The main reason that it’s often prohibited is due to the fact that double glazing changes the look of a property. Also, listed buildings can get very cold during the winter months, so secondary glazing can be installed to help keep your property warm. You can always uninstall in the summer months, especially if you have fixed secondary glazing.

If you worry about airflow during the summer months, don’t worry. You can have the secondary double glazing removed and then put back in when winter arrives.

What Are The Types of Secondary Glazing?

There are a few different types of secondary glazing that you can have installed in your home.

The lowest cost is for fixed secondary glazing is just that – fixed. The glass will fill the whole window, but you won’t be able to open it.

If you have sash windows in your property, you may want to opt for either the horizontal or vertical sliders. This type of secondary glazing is good, as it will allow you to access your sash windows easily.

Another reason why these are a good type of secondary glazing for sash windows is that it will let a good airflow into the property if you wanted to open both.

Top and side hung secondary glazed windows are another option, and these are as popular as the sliding secondary glazing windows are. However, secondary glazing costs will be more for these options.

What Are the Benefits of Secondary Glazing?

There are many benefits of secondary glazing, with noise reduction and energy efficiency being among the top bonuses.

Installing secondary glazing will reduce noise from the external environment entering your home. If you live in a busy area, this may be a great solution to achieve noise reduction.

Depending on the type of glass you install, you will be able to reduce the noise by around 85%, whether that’s neighbourhood children or the sound of traffic.

Another way that secondary glazing helps to reduce noise is that it creates a gap between the existing window and the secondary glazing, so more noise will be trapped and prevented from entering your home. The secondary glazing cost will be worth the money if this is an aspect you’re looking to achieve with this type of glazing.

Secondary glazing works better at emitting external noise than double glazing does. This is due to this larger area between an existing window and glazing secondary.

The energy efficiency of your home will be greatly improved by installing secondary glazing. Secondary windows will also help you to save money, as you won’t need to heat your home for as long. Warm air will stay within your property, instead of escaping out of the windows.

The secondary glazing cost will pay for itself in time to come. You will save money each year on your heating bills, which is a positive reason to add secondary glazing to existing windows. Plus, it’s cheaper than double glazing for windows.

Secondary windows can increase your property’s value and scalability. Just like double glazing, potential buyers will look at the type of glazing that the property has. The better the glazing, the more your property will be worth.

If your home suffers from condensation issues, installing secondary glazing can help prevent this from occurring and prevent you from paying out of other costs associated with condensation problems. This will help keep your property free from other problems, such as mould.

Another reason to justify the secondary glazing cost is the added security it provides to your home. It will be harder for anyone to break in. You will be able to increase your safety even more, depending on the type of glass you choose to use in your secondary glazing.

If you live in a listed building, adding secondary glazing to your existing windows is a perfect way to ensure you don’t alter the look of your property but make the property more homely and warm in the winter.

What Type of Glass Should Secondary Glazing Have?

Just like double glazed windows, secondary windows have many different glass options to choose from too. Depending on the reason why you’re having secondary glazing installed on top of your existing windows should determine the type of glass that you choose.

If you want secondary glazing to help reduce the amount of noise that enters your property, then opting for a thicker glass will help, and heavy-duty glass is the best option. The secondary glazing cost will be higher for glass that is thicker than standard glass, but it might be worth the money when thinking of the benefits it will provide you.

Standard glass costs will be the lowest and will still provide the benefits that are listed above. So if you are on a budget, but still want to improve your home, this is your best bet.

Can I Install Secondary Glazing Myself?

Many people ask themselves this question so that they can keep their secondary glazing costs to a minimum. If you are skilled at DIY, then it’s possible to reduce the costs significantly.

As with any window installation – and just as double glazing – a professional window fitter will charge more for labour costs. This can add up to be a lot of money. Depending on who you choose, they may charge up to and above £55 per hour.

If you do install the windows yourself, then the secondary glazing cost that you’ll need to cover will be for the windows themselves. This way, you could choose to go for the top end of the cost scale.

Always remember to measure your windows properly to ensure you purchase the right size and clean your existing windows before the installation occurs.

If you haven’t installed windows before, it would probably be best to allow a professional to do this for you instead. You should ask for quotes from a few professionals before you consider who to use. This will ensure you are getting the best deal.

Is There a Difference Between Secondary Glazing and Double Glazing?

There are differences between secondary glazing and double glazing, although they both do a similar job.

One of the main differences is that double glazing costs more than secondary glazing does, so if you’re keeping to a tight budget, you may be better off selecting secondary glazing as your preferred option.

Windows that have double glazing are always considered more appealing to homeowners. This is because they are more widely known and seem to be the choice that people go for. They’re what potential buyers look for when buying a new home.

Double glazing consists of two glass layers that will be of the same quality of glass. For example, if you have chosen a noise-reducing glass or standard type of glass, then both panes will be from the same glass material.

The two glass layers sit together within one frame. The frame can be made from different types of materials, but the most common material is uPVC, although you can have timber or aluminium.

There will be a slight space between the two glass layers of double glazing windows, and this area will be vacuumed, or gas will be put into the remaining space. This is to slow down the air movement from outside to help keep a good temperature within your home. This does not feature on secondary glazing windows.

Secondary glazing is slightly different as it doesn’t sit within the same frame. Instead, the secondary glazing sits separately from the existing windows. There’s a larger space between the secondary glazing and the windows that are already there.

If noise from your outside environment is the reason you’re thinking about having either double glazing or secondary glazing, then you should choose the secondary glazing option for your windows.

The reason for this is because the larger space between the secondary glazing and the existing window prevents noise coming into your home more than double glazing. The noise gets trapped inside.

In terms of heat and energy efficiency, both double glazed windows and secondary glazing will keep your home nice and warm. Just like secondary glazing, you can select glass for your double glazing that will help to insulate your home better than the standard range, although this will increase your costs.

Both types of windows will help keep the warmth inside and the cold out, but depending on the type of secondary glazing you have chosen, it may not be easy to ventilate you home quickly when needed. If you have chosen a fixed secondary glazing option, then you won’t be able to open your existing windows to allow fresh air in.

You will need to take the secondary glazing off first before doing so. This can be time-consuming and difficult if you’re removing them yourself; you may need to call in a professional.

If you have opted for the sliding or hinged secondary glazing, then you will be able to ventilate your home as and when needed. Double glazed windows will allow you to ventilate immediately.

Secondary glazing can be a good choice if only single glazed windows are currently installed and you’re renting your home. The main reason it would be a good choice is that you’re not removing the existing windows; you’re simply adding a frame that can be taken down.

Also, if you move out and you have paid for the secondary glazing, you can take it with you when you do. Although that doesn’t mean it’s guaranteed to fit the windows in the next property you move into, you will always have them on stand by.

Conclusion – Is Secondary Glazing for You?

The best way to decide is to determine whether you want to save money or if you are happy to pay the cost of high-quality double glazing.

Secondary glazing is cheaper and can be uninstalled without it affecting the main windows. Plus, if you’re a keen DIYer, it’s easier to install than double glazing.

If noise from the outside is an issue, then secondary glazing is for you. After it’s installed, you will feel the difference immediately and be happy with the noise reduction. This is a perfect solution if you live in a busy town.

To keep your home warm, double glazing and secondary glazing will work as well as each other. Also, due to the different glass options you have, you can choose glazing that will insulate your home better than standard glazing. This will come at a cost, but it will ensure long-term savings on heating your home during the winter months.

If you’re torn between double glazing and secondary glazing, then a good way to help you decide is to get a professional window fitter in to give you a free quote for both options and decide from there. If you’re making a significant saving by choosing secondary glazing, then it may be worth installing that instead of double glazing.

A professional window fitter will also be able to advise you on what type of window will work best for your home as each home is different, and each homeowner will have different needs.

If you live in a listed building, then, unfortunately, a secondary glazed window will be your only choice as many listed buildings are protected to prevent changes to the look and character of the building. Although you can try to apply for planning permission, it could be a waste of time.

The choice is entirely up to you. You can use the information above to help you decide if a secondary glazed window is for you.

A secondary window will suit most homes and many people like the look of them. The main benefit is the lower cost and the noise they can reduce to provide you with a quieter home.
