What Are the Advantages of Wooden Windows?

Wooden windows are an excellent choice for window replacements due to their given capacity to boost your home comfort and at the same time be environmentally friendly. Investing in double glazed wooden windows is therefore valuable for the following reasons:

Environmentally Friendly

Timber windows are made from trees making them a natural building material that is sustainable and environmentally friendly. Trees have been used in construction by societies around the world for thousands of years and are also known for giving lasting value to any window replacement.

The thicker the double glazed wooden windows are, the stronger and more durable the structure will be, which also helps to increase thermal insulation. As an environmentally friendly choice, timber frames emit less harmful gasses in the manufacturing process and rank high on energy efficiency.

Aesthetically Appealing

Wooden windows have a natural aesthetic quality that is visually pleasing. This element of beautification rises the level of home comfort and sets a relaxing ambience. Apart from the aesthetic value and environmentally friendly attributes, timber windows are known for their classical look. So, whilst timber windows will beautify any type of property, traditional looking houses, as well as houses made out of brickwork, tend to be best suited for double glazed wooden windows.

Energy Efficiency

Wood is considered to be one of the best sources of thermal insulation. It’s heating qualities is far better than that of aluminium or vinyl, and is higher in energy efficiency. The amount of thickness on the wooden frame contributes significantly to the heating and acoustic value making wooden frames an excellent window replacement choice. The amount of cold air penetration is vastly impeded enhancing home comfort, especially in winter.

Long Life Expectancy

In comparison to other types of double glazed windows, wooden windows last longer and are environmentally friendly due to timber being a renewable material. Timber windows are thus extremely durable and easy to repair. The cellulose and fibre contained in wooden windows allow them to remain pristine even under bad weather conditions. Double glazed timber windows are also strong enough to prevent warping or twisting for many years.

Why Use Wooden Windows in your Home?

Wood is a renewable material that is both environmentally friendly and increases energy efficiency. As such timber windows are embedded with thermal insulation properties, which naturally gives off warmth, and, henceforth, reduces the demand on heating and lighting costs.

Apart from thermal insulation, a good point to note is that wooden windows have a negative GWP (global warming potential) implying that over time they naturally decrease the amount of carbon dioxide released into the air. Thus double glazed wooden windows lower dependency on the power grid for heating or cooling thus raising energy efficiency.

Important to note is that investing in double glazed wooden windows has a double effect on energy efficiency and home comfort. Firstly, it reduces your energy consumption by enhancing heat during winter. Secondly, it reduces overheating in the summer thus retaining coolness.

Are Wooden Windows Better than uPVC?

Double glazed wooden windows are a great alternative to uPVC windows, giving homeowners a competitive and effective option for optimal energy efficiency. Whilst both uPVC and timber frames have ample benefits as window replacements, there are differences that one should consider in making your choice of double glazed windows.

Here are some advantages wooden windows have over uPVC:

Higher Thermal Insulation

Both uPVC and wooden windows will retain heat loss, however, the latter has the advantage of being a natural insulator. This offers higher thermal insulation and energy efficiency which in turn adds home comfort and reduces monthly bills.

Green Choice

Timber is a renewable building material and releases less CO2 in the manufacturing process than uPVC. It’s highly environmentally friendly as it can be recycled and is biodegradable. Thus in comparison to uPVC, wooden windows are more sustainable as a window replacement.

Longer Guarantee

Double glazed wooden windows have a longer warranty than uPVC windows. They have an average guarantee of 30 years, while uPVC windows usually have a 10-year guarantee. Also when it comes to damages, wooden windows are also considered to be much easier to repair than uPVC.

Wooden windows are timeless and are a best-suited window replacement for period properties. For ideal home comfort in traditionally looking houses, double glazed wooden windows will help to retain its classical features and maintain an authentic and elegant look.

Disadvantages Wooden Windows Have Compared to uPVC

Higher Costs

As mentioned before, wooden windows are more expensive than uPVC windows. This is because good quality timber is generally very high in cost. Yet, considering the longer life expectancy, they are a worthwhile investment option for double glazed windows.

Higher Maintenance

Wooden windows arguably require more maintenance than uPVC double glazed windows due to paint work. Although, depending on the type of paint finishing used, repainting of timber frames can be done in regular intervals of between 2 and 8 years.

Double Glazing: Benefits, Costs & Savings

A well insulated home will prevent less heat from escaping outside and mean that your heating won’t have to work so hard to reach the desired temperature. It’s reported that homes with single-glazed windows lose 20% of this heat through the windows and suffer from increased heating bills as a result.

The best way to combat this is with double glazing, which will not only keep more heat in your home but also reduce condensation and allow less outdoor noise into the home.

What is Double Glazing?

Double glazing is the name given to windows that have 2 panes of glass, rather than just one, providing another layer of insulation to the home.

The 2 panes of glass aren’t touching, between them is a gas, most commonly argon, which helps to increase the insulation further.

Why choose double glazing?

✔ Great insulation properties

✔ Reduced noise from outside

✔ Reduces damp in your home

✔ Higher security than single glazing

Benefits of Double Glazing

As we’ve mentioned, double glazing acts as an added layer of insulation for your home, helping to keep the heat in and lower your heating bills. This is a major benefit of installing double glazing but there are many more:

• Helps to prevents draughts from entering the home.
• Less outside noise will make its way into the home.
• Reduced condensation on the inside of the windows.
• Increases the security of your home as 2 panels of glass is much tougher to break than one.

Disadvantages of Double Glazing

Keeping the heat in your home during the winter is one of the biggest benefits of double glazing but it’s not appreciated quite so much during the summer, when it can make rooms hot and stuffy. You might want to consider having the windows tinted which will reflect some of the sunlight away, preventing outdoor heat from coming into the home, but this will add to the cost.

Double glazed windows that aren’t airtight are susceptible to condensation forming between the glass. Eventually, this could lead to the whole window needing to be replaced. However, if you hire a fully-qualified window installer, this shouldn’t be a problem.

How Much Does Double Glazing Cost?

There are many factors at play when determining how much double glazing windows could cost, including: size, style, framing material and the energy rating of the glass. When it comes to the energy efficiency rating, glass that’s A-rated typically costs around 10% more than glass with a lower rating. However, what you pay for a more efficient glass for your windows, you’ll soon make up for in savings on your energy bills.

On top of the price of the double glazed windows themselves, you’ll also have to consider the installation costs. Your location can play a factor here, with homeowners in London facing higher prices for installation.

Wooden Windows Double Glazing Costs

The cost of timber frames with double glazing will differ depending on the style and size. Use the tables below to find out how much timber casement and sash windows could cost before installation.

Timber Casement

Casement windows are the most conventional type of window in the UK, hinged on one side and opening outwards. The price for installing double glazed timber casement windows will vary depending on the size and whether they’re being installed on the ground or upper floors.

Size	Price
600x900mm	£800 – £900
900x900mm	£1,100 – £1,200
900x1200mm	£1,275 – £1,375
1200x1200mm	£1,400 – £1,500
1800x1500mm	£1,750 – £1,900

Timber Sash

Sash windows tend to be quite tall, with the lowest pane of glass sliding upwards to open. When it comes to installing double glazed timber sash windows, the same factors can affect the cost as with timber casement windows: size and floor they’re being installed on.

Size	Price
600x900mm	£1,500 – £1,600
900x900mm	£1,650 – £1,750
900x1200mm	£1,850 – £1,950

All of the potential costs we’ve highlighted in the above tables are before the installation, which you will have to add on to the price of the windows. To get the best deal possible on installation, we highly recommend comparing quotes from multiple sources.

What Can Push the Price of Double Glazing Up?

It’s important to take into account that certain additional features, offered by many double glazing companies, can push up the cost of a widow installation.

For the cheapest double glazing, stick to uPVC windows but if you’re considering something beyond that, you’ll need to consider the following:

Frame material

Price can vary dramatically between window frame materials, for example aluminium frames could be as much as twice the cost of uPVC. You may however want to weigh up the pros and cons of each material, as some may have a longer lifetime or provide additional energy saving benefits.

Glass efficiency

A-rated windows offer a higher level of energy efficiency, however they will cost more than B-rated windows. You also have the option of having low emissivity (low-e) coatings added to your glass which will increase energy performance by up to 40% but it will come at a higher price.

Savings From Double Glazing

The Energy Saving trust have calculated the amount of money single-glazed homes can save each year by installing double glazing. These savings are for typical gas heated homes in England, Scotland and wales.

Energy rating	Detached	Semi-detached	Mid terrace	Bungalow	Flat
A	£120-£160	£85-£110	£65-£90	£55-£75	£40-£60
B	£110-£145	£75-100	£60-£80	£50-£70	£40-£55
C	£110-£135	£75-£95	£60-£75	£50-£65	£40-£50

Double glazing will take a long time to pay back through energy saving benefits and should be considered a longer term investment; the installation will create a warmer, quieter environment while increasing the value and aesthetic appeal of your home.

Are Double Glazing Grants Available?

Since the Green Deal closed in 2015, there are currently no government schemes available that can help finance your double glazing installation in the UK. However, there are several other schemes around that could potentially help with the payments:

• Home Repair Assistance Grant
• Care & Repair
• Housing Aid for Older People Grant
• Home Improvement Grants

Do Double Glazed Windows Require any Maintenance?

Double glazed windows require little to no maintenance, especially when they’ve only recently been installed.

It’s a good idea to open and close your windows every now and then to make sure that the hinges are still moving as they should. You should also test the locks on the frame, to give you the peace of mind that they’re still locking as they should.

Keeping the windows clean is an important part of window maintenance as it can help to prevent muck and debris building up around the frame that could prevent the necessary parts from moving. It’s possible to install self-cleaning double glazing, which breaks down dirt that makes its way onto the glass, which you should only wipe using products approved by the manufacturer.

When having double glazing installed around your home, remember to consider the warranty as you’ll be covered by the manufacturer in the unlikely event that the windows encounter any issues during that period.

Are Your Windows Double Glazed?

There are 2 simple ways to check if your home is already fitted with double glazed windows:

1. Take a look at the window’s inside edge, if you have double glazing then you’ll see 2 panes of glass with a space in between. Otherwise, there will be just 1 pane of glass which means that your window is single glazed.
2. Open the window and press a finger to either side of the glass, if they’re close together then you have single-glazed windows, if there’s a fair amount of space between your fingers then you’re already enjoying the benefits of double glazing.

Secondary Glazing

A alternative to replacing your current single-glazed windows with double glazing is secondary glazing. This involves a single pane of glass being added to the existing pane, making it a secondary pane.

Secondary glazing is a cheaper alternative to having double glazing installed and you’ll still be able to benefit from reduced heat loss and listed buildings don’t require any planning permission.
