Since modern housing design began back in the late 1960s, homeowners have always been looking for a way to connect the outside of their properties to the inside. Whether that be with a balcony that overlooks a busy city street or a garden that is home to plenty of social gatherings over the summer months. Whatever it may be the homeowner has on the outside, having a large opening out back really helps with providing the illusion of more space within the home and giving the home lots of airflow. The sliding door was previously the best choice, and for many people, that still is the case. The sliding door takes up very little extra space when it’s open and gives the household wonderful views of the outside when it is closed.
However, for those with the space, the modern bifold door has started to take the market by storm as the preferred option. Whilst the bifold door may not provide the completely clear view that the sliding door does when it is closed, the sheer breadth of the opening is unmatched. Essentially acting like opening the entire wall, the bifold door is just superb as a modern innovation.
Here at Dempsey Dyer, we provide modern bifold doors in both aluminium and timber variants, each with its own unique benefits and stylistic appeal. Both are excellent choices, but it depends on what the homeowner is after when choosing between them.
In truth, the folding door has been a part of homes since ancient times. Their first recorded use seems to date back to the ancient Romans in various building types and applications. The concertina design (as it is otherwise known) gives the building a difficult entranceway that can take up a lot of space and provide a large opening, likely perfect for merchants and the like.
The bifold door fell out of fashion somewhat over the centuries until very recently, when the double glazed concertina door came back into style. Before this innovation, bifold doors acted as folding walls of a sort, but their lack of structural integrity compared with an actual wall left a lot to be desired. However, when compared to a window, the structure is not massively affected, especially with a back door into the garden.
Bifold doors operate on a rail system on the top and bottom with hinges between each panel. The door has one ‘master door’ at the end on either side or in the middle that can open independently of the others. The rest can then be folded into starting from the master door across the length of the installation. If the master door is in the middle, then the door opens both ways towards the edges.
The design has recently taken the British home design market by storm due to its modern finish and superior ability to provide the illusion of space over the sliding door. Here at Dempsey Dyer, we provide bi-fold doors to trade customers and homeowners in timber or aluminium.
The timber bifold door combines contemporary design with traditional materials. With the advent of modern resin and varnishing, timber no longer degrades in the weather in the same way that it used to. There was a time when purchasing a new timber installation came with a caveat of constant maintenance to keep it from rotting in the humid British weather. Luckily this is no longer the case. You can enjoy the thermal insulating properties of timber as a material with no concern of degradation or deterioration over the years!
We provide three timber species for our bifold doors:
Accoya is the high-performance species that we provide and is made from sustainably sourced softwood. With class 1 durability, you’ll struggle to find better on the market for longevity alone.
Sapele is a common hardwood used for both windows and bifold doors with a class 3 durability classification qualifying it as moderately durable. Don’t let the term fool you, though. This wood species is still able to achieve many years of service in the home.
Our final option is the European Oak that we source through an FSC (Forest Stewardship Council). European Oak has a class 2 durability classification and is excellent for the homeowner looking for an authentic and sustainable bifold door.
Aluminium bifold doors are likely the reason that the bifold door has really taken off in the last ten years. With slim frames, occupants can enjoy exceptional views of the garden whilst also having the option of opening up the door and potentially providing an opening as large as the wall.
Our aluminium doors are able to circumnavigate the issues that once came with aluminium thermal efficiency. We use modern thermal break technology to stop aluminium elements from coming into contact with each other. In doing this, we prevent global cooling of the whole installation and affect your home’s thermal efficiency. With aluminium bifold doors, you can enjoy modern levels of comfort with modern design styles too.
If you’re interested in a bifold door from Dempsey Dyer, whether you be a trade or homeowner, we provide quick quotes right here on our website with our online pricing tool! You can also contact us directly through our contact form with any specific questions you may have.
Modern homeowners have never had more choice of materials and styles for their installations than they have today. Especially with the advent of modern technology in manufacturing, homeowners can now receive exceptional quality across the board no matter the material or style they choose. As a result, it is important as an installer that you are aware of the differences between the various products we sell here at Dempsey Dyer. If a customer asks, it is good to be well informed and aware of what each type of door provides for the home in contrast to the others. Homeowners will not be as well informed as you on the variety of doors they can choose from, so they’ll trust you to provide them with a thought out recommendation. Today, we wanted to break down the different doors that we provide so that you can be fully informed about the products that we sell.
Timber doors have come a long way in the centuries they’ve been used across the UK. Long gone are the days of weather degradation and rotting front doors. Nowadays, modern coatings and manufacturing processes have provided timber front doors with the ability to withstand weeks of poor weather conditions without showing any sign of the degradation we might have come to expect some years ago. We use three different species of wood for our timber front doors. The Accoya range is a high performance, modified timber made from sustainably sourced softwood. It has ‘Class 1’ durability, which is the highest level of durability for timber. Our Accoya products are premium when it comes to timber installations. We also provide European Oak products, which would be one tier down. European Oak has a ‘Class 2’ durability rating and has the lightest colour of the three species we provide. We source this particular species through the Forest Stewardship Council to ensure that we are sourcing this species sustainably. Finally, the next tier down is the Sapele range, which has the darkest colour of the three species and has a ‘Class 3’ durability classification, making it moderately durable. This species comes from West Africa and Cameroon and is an attractive choice regardless of having the lowest durability rating. Timber doors are perfect for the homeowner who is looking to add a nostalgic and timeless look to the front of their home. Authenticity is a key selling point and an excellent reason for customers to purchase timber products.
Next up is our range of uPVC front doors. uPVC is one of the three most widely used synthetic materials on the planet because of its relatively low production cost and its exceptionally high durability, low maintenance and thermal efficiency. uPVC is also wonderfully customisable and can easily be given a woodgrain finish to look like a timber door. uPVC doors are perfect for the homeowner looking to make an affordable addition to their home that still provides excellent performance across the board. uPVC front doors are able to last anywhere between 20-30 years and will provide consistent protection from the outdoors throughout that entire life span. uPVC requires very little maintenance to remain in tip-top condition so your customers can rest easy with a ‘fit and forget’ front door.
Aluminium front doors provide the home with a truly modern entranceway that is particularly on-trend at the moment in home design circuits. Critall like design made to replicate the industrial art-deco look has shown an explosion in the demand for aluminium and aluminium looking products. Homeowners looking to give their home something new that makes a statement to passersby and visitors alike will absolutely love an aluminium front door. Aluminium also no longer has the issues of thermal efficiency that it once did. With the use of modern thermal break technology, the aluminium elements of the door are separated from each other so that heat does not pass easily from the inside to the outside. As a result, the aluminium door is just as thermally efficient as a modern timber door or a uPVC one.
Finally, we also provide composite doors, a completely modern innovation that combines many of the materials mentioned earlier into one outstanding product. We provide two types of composite doors. The first is the foam-filled variant. Foam-filled composite doors are the less strong of the two types, the other being the timber core variant. However, foam-filled composite doors are known to be more thermally efficient than the timber core.
On the other hand, Timber core is much stronger and able to withstand a lot more punishment. As a result, it is really up to the customer which element they would like to prioritise over the other. Composite doors are just as customisable as uPVC, meaning that they can be given a woodgrain finish should the customer wish it.
So there you have it, our quick guide to the kinds of front doors we provide here at Dempsey Dyer! Our front doors all come with customisable hardware that is all of the highest quality.

uPVC was first manufactured back in the 1930s, but it didn’t become one of the major manufacturing materials until the mid-1950s. Since then, almost every decade, uPVC has grown massively in popularity. It really took off during the 1980s in Britain when double glazing also became a standard in modern home installations. Since then, both uPVC and double glazing have become staples of the modern home. Older British homes that haven’t had uPVC or double glazing installed yet are renowned for leaking heat, resulting in colder homes during the winter and hotter homes during the summer. With the introduction of double glazing and uPVC back in the 1980s, homes that had previously been difficult to keep warm and were a threat of overusing gas and heating systems now had a way of insulating their homes and making sure that the heating they were spending their money on, wasn’t leaking out of poorly insulated installations, like outdated timber single glazing. So, why has uPVC remained popular to this day, 40 years later? After such a long time in use, it still remains the most widely used material in home renovations and installations. Here at Dempsey Dyer, we wanted to focus on the key benefits of uPVC and how it continues to improve homes across the country to this day.
As mentioned, thermal efficiency has always been one of the major positives of having uPVC installed in your home. Timber is a natural insulator, which is why it has been used for centuries as the main material for installations such as doors and windows. However, timber, if not treated properly, degrades significantly over time. This degradation can lead to those installations becoming inefficient over time. This isn’t the case these days with newly installed timber because of how the wood has been treated and manufactured. However, older installations have not had the proper treatment before installation and therefore struggle to maintain their thermal efficiency. Therefore, as uPVC can achieve the same level of thermal efficiency, it makes sense as a replacement for older timber installations. As Britain moved away from timber, it naturally moved towards uPVC for this reason.
uPVC also counteracts timber’s lack of longevity by being an incredibly durable and weather-resistant material. As it is synthetic, rain and wind do not have much of, if any, effect on the material. Timber naturally absorbs water unless coated properly and therefore can become rotten or mouldy relatively quickly. uPVC has no such issue. All it requires is a wipe down every so often to remove any deposits of dirt or grime to keep uPVC windows and doors clean and as good as new. As a result, uPVC has a relatively long lifespan compared to older wooden installations. With the promise of similar levels of thermal efficiency, combined with the longevity and low maintenance requirements, it is no wonder that uPVC was the best choice for new installations back in the 1980s.
Old timber doors and windows are also at greater risk of being broken into or broken through because of the natural degradation that starts to set in after so many years. uPVC offered homes a chance to modernise the locking systems of the various openings to the outside. Multi-locking systems around the frames enable doors and windows to have much-increased levels of security across the board.
However, its exceptionally low price point is uPVC’s greatest strength compared to timber, composite, and aluminium. uPVC offers equal levels of thermal efficiency, security and durability whilst also being incredibly cheap to produce. Installations made from uPVC are much cheaper than their timber and aluminium counterparts for this very reason. Furthermore, uPVC is fully recyclable, meaning that once the installation has reached the end of its natural lifespan, the material is melted down and reshaped into something new! The combination of its recyclability and its low price point gives uPVC modern benefits when compared to modern uses of timber and aluminium. Timber has had a resurgence in its usage because the drawbacks of older installations have been negated with modern coating and manufacturing processes. However, uPVC remains popular because of its low price point and recyclability.

With energy prices across the globe starting to rise significantly, it is important to keep insulation and energy efficiency at the forefront of our priorities when it comes to installing doors in the home. Homeowners are rightly concerned about their impact on the environment and saving consistently on their monthly bills. Here at Dempsey Dyer Ltd, we’re well known for our high-quality timber doors that come in various styles and sizes, whether they be bifold, entrance or patio. Therefore, we wanted to focus on timber doors and energy efficiency today and answer the question: Are timber doors energy efficient?
Timber is a natural insulating material. Humans have been building with wood for around 10,000 years, and with good reason! As a material, timber has small air pockets that help insulate it internally from outside temperature changes. It was only about 100 years ago that timber started to go out of fashion as a material to build the entire house. That doesn’t mean that it is still not an extremely useful and diverse material for specific elements of the home! Wood and timber doors are among the most popular front doors, with composite and uPVC standing alongside.
Timber’s insulating properties are one of the reasons that it has held firm as one of the most popular materials for building for the last 10,000 years. Wooden doors that seem to be losing much heat are much more likely to be lost through poor seals that have aged poorly since their installation. Therefore, when installing a new door, timber is still one of the best options for insulation and energy efficiency. Around 80% of the money we spend on energy in our homes goes towards heat, so we must focus on the insulating properties of our doors so that we can maintain high levels of energy efficiency and therefore save money.
How does timber compare to the other materials on the market regarding energy efficiency? uPVC is a modern innovation that has quickly made its way into the top 3 most used synthetic materials worldwide because of its relatively cheap manufacturing cost with high strength and durability properties. uPVC is an excellent insulator, as it does not conduct heat at all. Windows and doors made from uPVC are praised for low maintenance, 25-year life span and energy efficiency. However, uPVC doors are no more energy-efficient than timber doors have become known to be. Only managing to match the insulating properties of timber, uPVC has not managed to become more energy-efficient than wood. Therefore, homeowners looking for a more stylised front door will still want to look towards timber due to its classical look.
Similarly, composite doors, the other major material option, have also not been able to achieve higher levels of efficiency than a timber door. However, timber doors will degrade over time; composite doors are specifically designed to last for decades. Their high price point matches their high-performance nature as a premium option for front doors. However, with modern innovations, certain timber doors, like those in our Accoya range, circumnavigate this problem. Our Accoya doors go through a process that removes the wood’s ability to absorb water, meaning that it will last much longer and be resistant to shrinking, swelling and decay.
Timber sits in the middle between these two alternative options. However, it remains on equal footing with the other two regarding energy efficiency. Where timber shines, however, is its sustainability potential. uPVC boasts a relatively high (for a synthetic material) recyclability rate of 50%. However, wood is completely biodegradable as a naturally occurring resource and therefore is 100% recyclable.
Similarly, as composite doors are made of several different materials, they can not quite reach the same levels of sustainability as wood. That’s not to say that these materials are not sustainable. Here at Dempsey Dyer, we are fully aware and committed to using environmentally friendly materials; however, timber always comes out on top when it comes to impacting the world around us.
So the answer to the question: Are timber doors energy efficient? Yes! Timber doors are wonderfully energy efficient. Naturally insulating homes for 10,000 years, wood has kept us warm since we first discovered how to put logs together to protect ourselves from the rain. Homeowners looking to invest in a new door can be assured that going timber is not a mistake when it comes to energy efficiency, even with the new materials on the market boasting similar insulation properties. Furthermore, timber is a perfectly sustainable material to use as it is fully biodegradable and recyclable. Whether the homeowner is concerned with saving money on their energy bills or is worried about their effect on the environment, timber doors are an excellent choice.

What are the signs that you need to replace timber windows and doors? If you have wooden windows and doors in your home, then they might already be sending you signals that they might need changing. While these windows and doors have a fantastic, classic look, they do have plenty of drawbacks. Your timber windows and doors will need a lot of regular maintenance and upkeep, and even then they might need repairs after just a few years.
So, what are the signs you’re looking for? One of them could be whether your living space feels cold and uncomfortable, as your wooden windows and doors may be causing this. Another sign might be if condensation is building up on the window, and this could mean that the timber is starting to wear down. And, if your window frames are beginning to crack, twist or even discolour, then their age might be getting the best of them.
At Dempsey Dyer, we can help you replace timber windows and doors if you see any of the signs. We can offer high-quality timber windows for commercial clients, and we can help homeowners get new windows for their property as well. Our timber windows and doors are market-leading, and we use resilient Accoya wood for a high-quality finish. If you’re interested in replacing timber windows and doors, get in touch with us today!
If your living space is feeling cold or uncomfortable, then it could be a sign that your timber windows and doors are beginning to struggle. If you have older windows in your property, then they might have single-glazed glass which doesn’t offer a lot of insulation. And, while timber is a natural insulator, the material can begin to wear down over time. Because of this, gaps can emerge within the window and door frames that allow cold air and draughts to rush into your home.
As a result, you should check your timber windows and doors if your home feels cold without you relying on your central heating. Your window might have cracks in the wood, or the whole frame may have warped out of shape. Not only that, the single glazed glass may be struggling, and you could need replacement double glazing as well. Replacing your timber windows and doors, though, ensure that you can make your home warmer and more thermally efficient.
Another sign you may need to replace timber windows and doors is condensation. Condensation is a mist that builds up on the glass panels in your windows and doors when hot and cold air clash. Most glass units, including double glazed units, are designed to keep the hot air inside your home and the cold air outside it from colliding. So, when they do, it could be a sign that your timber windows and doors are beginning to wear down.
You should check your timber windows and doors for whether there are any gaps in the sealant. If the sealant in your glass panels has broken, then you’ll need to replace the glazing in your window or door at least. And, while condensation can build up on the inside and outside of your glazing, the best way to stop it is by getting new windows or doors altogether. When you do that, you can enjoy a more durable, weather-resistant window or door that doesn’t have issues with condensation.
Over time, the signs you need to replace timber windows and doors only get bigger. And, after a while, the signs become too obvious to ignore. One of the main signs is weather damage, which is usually an accumulation of multiple years being exposed to poor weather conditions. Wooden windows and doors struggle in wind and rain, which can cause the timber in your profiles to crack, twist, and warp out of shape.
You should regularly check your timber windows and doors for weather damage, including cracks and gaps in the frame. And, if the profiles have warped out of shape, then you should look to reseal your windows or doors. However, you could replace your timber windows and doors with brand-new designs that have more resistant profiles. With Dempsey Dyer, you could pick uPVC, aluminium and even Accoya timber windows and doors that are much more comfortable in bad conditions.
