Secondary Glazing Costs for 2020


What Does it Cost to Install Secondary Glazing?

Investing in secondary glazing installation is a good idea for many reasons. Firstly, it’s cheaper than purchasing double glazing, but it offers many of the same benefits. This makes it a good choice for homeowners who want to keep costs low.

The exact cost of installing secondary glazing is dependent on a number of factors. For example, if you live in an old, listed building then there’s a chance that the size and shape of the windows in your home may be irregular, and that will need special windows so that they can fit.

Each home or office, however, is different, and the type of windows you order, as well as the required size and the material of the windows, will all contribute to the cost of installing secondary glazing.

You also need to take into account the labour costs involved with secondary glazing, as it’s recommended that you employ professional window fitters. The amount of time that the window fitters will need to complete the job will depend on the number of windows are being fitted.

But in most cases, secondary windows can be easily fitted in a day, even if it is multiple windows being fitted at the same time. Secondary glazing is an easy job, and it takes a lot less time than getting double-glazed windows fitted in your home.

It’s very important to remember that you will only encounter the cost of installing secondary glazing once, and in the long run, you’ll make back your money. Why? Because a building that has secondary glazing, as opposed to single glazing, will be far more energy-efficient.

And the benefit of energy efficiency is that your heating bills will reduce, as less heat will be escaping through your single glazed windows. Retaining heat inside the home means that you won’t need to put on the fire or radiator for as long or as often.

How Much Money Can Investing in Secondary Glazing Save You

It will depend on the size of your home, as well as the number of windows that you install secondary glazing on. The type of secondary glazing that you install in your home will also change what your original outlay is. For example, it can cost you twice as much to install sliding secondary glazing than it does for fixed secondary glazing installation.

For the average home, you can expect to knock about £45 a month off your energy bills when you’ve installed secondary glazing.

If you install the cheapest form of secondary glazing – which is magnetic secondary glazing – then your original outlay will be somewhere between £1,500 and £2,000. That means that you will have paid off your investment through savings on your energy bills after three years.

Fixed secondary glazing is the next tier up in terms of installation cost, and they tend to set you back somewhere between £2,000 and £2,500. If you pay this amount for your new windows, then your £45 a month saving on your energy bill will mean that you’ve paid off the investment after four years.

Lift-out secondary glazing windows are the second most expensive form of secondary glazing. They can cost anywhere between £3,500 and £4,000 to have installed. For your £45 savings on your energy bill to pay off the original outlay then it will take about seven years.

And the type of secondary windows that cost the most to install are sliding secondary glazing windows, and to have them put in your home, it can cost between £4,500 and £5,500. For the average home, where you will save £45 a month on your energy bill, then this means it will take 8 years for the investment to pay itself off.

The Key Factors That Can Affect How Much Secondary Glazing Costs

The biggest factor that will contribute to how much you pay for secondary glazing is simply what type of secondary glazing that you choose. And the type that you will choose will depend on your home. But you should always remember that secondary glazing will save you money compared to getting double glazing fitted in your home.

If you live in a listed building, then you will have no choice but to get secondary glazing, as double glazing may require planning permission. And planning permission isn’t cheap. So, to keep costs down, it’s always a better idea for people who live in listed buildings to get secondary glazing, as then there’s no need for planning permission, as you won’t be altering the existing window outside your home.

The cost of labour has to be accounted for, too. But you will save money in the long-run if you employ high-quality window fitters. They can also take care of ordering the windows for you, measuring, and doing everything, so that all the difficult work is out of your hands. You can find quotes easily for secondary glazing experts to ensure you go with a company that fits your budget.

How Installing Secondary Glazing Can Save Energy and Money

The biggest issue with single glazing is simply that it allows too much heat to escape. The two best solutions to this problem are double glazing and secondary glazing. Secondary glazing is far cheaper than double glazing but it will provide many of the same results of double glazing. You will just have to add a second layer of glazing to your home without needing to remove your existing windows.

Installing secondary glazing means that your home will instantly be better insulated. It’s estimated than in the average British home, a third of the heat that escapes your home is through the windows. Getting secondary glazing installed in your home will dramatically reduce heat loss through the windows.

It will also eliminate any drafts. In winter, this is a Godsend. It means that you don’t need to have the central heating or fire on for anywhere near as long. Depending on how you heat your home, this could save you in electricity, as well as heating costs.

On average, a small UK home will spend approximately £100 a month on energy, but once you get secondary glazing, then immediately after installation, you’ll find your bill reduced by £30. A medium-sized home will spend about £150 a month on their energy bill, but this will drop by £45, after secondary glazing installation.

A large-sized home can spend closer to £200 a month on energy, but you’ll notice that your bill is reduced by £60 after secondary glazing installation in your home. In the long run, the secondary glazing cost is well worth it, as you’ll simply be saving money, as well as being more comfortable in your home after you have installed secondary glazing.

Other Ways You Can Make Your Home More Energy Efficient

Besides fitting secondary or double glazing in your home, there are another few ways that you can make your home more efficient when it comes to energy consumption.

Firstly, when a window fitter comes to fit your secondary glazing, you can ask them to check the existing windows, and see if they need a new seal.

Secondly, you may wish to check your door. Just like single glazed windows, having the wrong door in your home can cause heat to escape and for a draft.

The best door, just like double glazing, will offer a perfect seal, but these types of doors may not be possible to fit inside listed buildings, as they could alter the external look of the home, and that might require planning permission. Also, just like double glazing, doors of this type tend to come in standardised sizes, which means they can be difficult to fit in older homes.

If you want to save money on your heating bill, then you should consider getting a ‘smart thermostat.’ These are excellent devices that ensure that the heating is only on when it needs to be on. Your home will stay warm, but you won’t overpay on heating at the same time.

When it comes to electricity, then it’s always important to have white goods that are efficient too. If you’re planning on replacing your old washing machine or fridge, then make sure that you buy one with a Grade A rating.

Remember, the best way to have an economical and efficient home is by spending money upfront. Buying a new fridge is expensive, just like secondary and double glazing is expensive, but you’ll save money in the long run, and you’ll be free from bigger monthly outgoings for a long time too.

Is Secondary Glazing a Cheaper Option than Double Glazing?

Yes. The installation of secondary glazing, as well as the cost of materials, is much lower than standard double glazing. Just how much the secondary glazing cost is as compared to double glazing will depend upon the type of secondary glazing that you get fitted.

On average, though, secondary glazing costs about three-quarters of what double glazing costs. And you won’t need your existing windows to be removed when you go for secondary glazing, which is not the case for double glazing. It’s a bigger job to get double glazing installed, as opposed to secondary glazing, and that’s why it costs a lot more.

What Types of Secondary Glazing Are Available?

Secondary glazing comes in a variety of forms. But there are four types of secondary glazing that are the most common, and each of them will cost you a different amount.

The first type of secondary glazing that’s available to you is ‘Magnetic’ secondary glazing. As you can guess from the name, this system of secondary glazing works via magnetised panels that are attached to your existing windows, allowing for a secondary layer of glazing.

Magnetic secondary glazing is the cheapest form of secondary glazing on the market and will cost you approximately £150 per sqm. The only downside of this form of secondary glazing is that the magnetic strips will be visible, so it doesn’t offer as clean aesthetics as the other three types of secondary glazing.

The second type of secondary glazing that you can opt for is called ‘Fixed Secondary Glazing’. Again, as the name suggests, this form of secondary glazing is fixed. And that means that you can only access the existing window if you completely remove the fixed layer of secondary glazing.

This makes it a good option for certain windows and not for others. For example, if you have sash windows, then fixed secondary glazing would not be a good option, as you would no longer be able to open the sash windows. But if you don’t have sash windows, and you don’t need access to your existing window, then this is a good option, as this is the second-lowest on the spectrum of secondary glazing cost.

The third type of secondary glazing is known as ‘Lift-Out Secondary Glazing’. This secondary glazing is great for anyone who wants to be able to easily remove the secondary glazing so that you can get access to your existing windows.

They’re also good for anyone who wants to be free of visible magnetic strips, as you’d get with magnetic secondary glazing. Every sqm of lift-out secondary glazing costs approximately £300. This is the second most expensive available in terms of secondary glazing cost.

When it comes to secondary glazing cost, then the most you can pay is for the fourth type, which is for ‘Sliding Secondary Glazing’. This will cost you about £400 per sqm.

But this offers the best quality in terms of usability. You can slide it out of the way if you want access to the windows underneath. It offers excellent noise reduction and it’s highly effective against heat loss.

What Are the Main Benefits of Installing Secondary Glazing?

Secondary glazing offers many of the same benefits as double glazing but it costs much less than double glazing and doesn’t require the existing windows to be removed.

The main reason why someone would install secondary glazing in their home is that it improves energy efficiency. That’s because heat cannot escape as easily as if you have a single layer of glazing. And it can also stop any draft entering through your windows.

After the installation of secondary glazing, you will also find your home quieter, as well as warmer, as external noise will not be able to penetrate the two layers of glazing as easily.

If you live somewhere that has a lot of external noise, then secondary glazing is a cost-effective option that gives you many of the benefits of double glazing when it comes to reducing external noise. It leaves you free to enjoy the comfort of your home without being disturbed by a busy street.

Does Secondary Glazing Reduce Noise?

Yes. Secondary glazing does reduce noise. In fact, after energy efficiency, noise reduction is the second most common reason why people choose to pay the secondary glazing cost and to have it installed in their home. Secondary glazing offers similar results as double glazing in terms of noise reduction.

If you dream of being free to enjoy the silence in your home, then investing in the installation of secondary glazed windows is a good choice, as you will be thoroughly impressed with the noise reduction that they offer.

Is It Cheaper to Install Secondary Glazing Without Professional Help?

Yes and no. It depends on the form of secondary glazing. Installation is simple with some forms of secondary glazing, such as magnetic secondary glazing, but this is not the case with the other three forms of secondary glazing.

Many window fitters will be happy to visit your home for free to offer you a quote if you’re having several windows fitted, or they will be happy to talk to you on the phone about your options. It’s always worth getting an expert in for any major.

People who live in listed buildings should always call in an expert as you might have restrictions on what is available to you. But, of course, secondary glazing will be a much better than double glazing option for you, as you’d need to have the current windows to be completely removed if you went for double glazing. That isn’t an option in some listed buildings.

How to Install Secondary Glazing Yourself

Unlike double glazing, secondary glazing can be fitted in some cases at home by people who have some experience with DIY.

The most important thing if you’re installing it yourself is to get your numbers right. If you don’t measure properly, then you’ll order the wrong sized windows, and that means that you won’t be able to fit them on your current windows.

This is another reason why getting an expert in is a better option. If you do measure yourself, then add a couple of centimetres onto the size, as the glass will move over time. Adding a few extra cms will give you some leeway.

Once your order has arrived, then you should disinfect the new panel, as well as the current frame of your existing windows, before you consider fitting the new panels.

Then you simply need to follow the instructions that come with the product. Most likely, if you are to fit it yourself, then you will have gone for the magnetic option, in which case it’s always important to put the magnetic tape on the new panels and to put the aluminium tape on your current windows.

This makes it easier to remove and put back on, which is handy if you need to get access to your original windows at any point. Each product is different, so always check the instructions prior to installation. And also, make sure that you get rid of the outer film once you’ve fitted the new panels to your old windows.
