Sit back, relax, and learn more about Dempsey Dyer – the industry specialists.
Watch nowuPVC 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sure that the heating they were spending their money on, wasn’t leaking out of poorly insulated installations, like outdated timber single glazing.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.

Unplasticised Polyvinyl Chloride, otherwise known as uPVC, is a low maintenance alternative building material that can substitute for timber or aluminium. uPVC has become a popular choice for homeowners looking for effective thermal insulation and noise reduction and is considered a more cost-effective alternative to more traditional materials due to its lower initial price point. The material is made from vinyl polymer bound to chlorine atoms and boasts very high strength. uPVC is among the top three most popular (by usage) synthesised plastics in production worldwide!
Aluminium is a traditional, high-price point material for windows and doors. Aluminium has often been considered the best material for windows because of its longevity, durability, and providing a distinctive, high-quality look to a building. However, it has been criticised over the years for its poorer thermal performance compared to other materials, although this can be circumvented with modern innovations. As uPVC begins to take over as the most popular material on the market, is it time to say that uPVC is now the more attractive option. Or is aluminium still the ultimate choice?
uPVC windows are exceptionally durable for the low price point at installation. Highly resistant to wind and rain, uPVC is an incredibly strong material, proved by its popularity across many industries. Due to its composition, uPVC will not rust or rot and is resistant to chemical erosion. The overall low maintenance of uPVC is an incredibly important part of why they are so attractive to homeowners. The composition is designed to be a ‘fit and forget’ installation that does not require any special coating to ward off dirt, dust and bacteria.
On the other hand, aluminium has a much longer lifespan than the uPVC at around 45 years! Therefore, the higher price point of aluminium windows is reflected in them is a long-term investment for homeowners looking to increase the value of their homes. However, the low price point of uPVC means it could be a much more cost-effective solution for the modern homeowner.
Both uPVC and aluminium are lightweight materials that are easily manipulated. As a result, installation is considered an easy process with both materials. In terms of production, aluminium requires large amounts of energy for the binding process in creating the alloy. Therefore, whilst the installation process can be relatively simple, aluminium production is complex. uPVC, on the other hand, is very easily produced and sourced. As it is among the top three synthetic plastics, a consistent supply of uPVC is available for installations, which is reflected in its low price point.
Aluminium as a material has taken steps to become a better heat insulator. Through a thermal break, aluminium elements of the installation are separated to prevent global cooling of the whole installation. The material itself has been called a poor insulator, and homeowners may have cold window sills in the winter. However, the modern innovation of thermal breaks ensures that aluminium is a high-performance thermal insulator. uPVC, on the other hand, is an exceptional heat insulator. The material does not conduct heat, preventing temperature shifts over the year. Therefore, whilst also being a cheaper alternative to aluminium, the energy efficiency of uPVC is relatively the same, if not better. Homeowners can be sold on much lower energy costs over the course of the year due to not needing to regulate the temperatures of their homes with fans or heating with both uPVC and aluminium windows.
Aluminium has a sleeker and higher quality ‘look’ to it. Traditionally, aluminium has been considered the premium material when it comes to windows. The lower price point of uPVC, however, coupled with its various benefits, is extremely significant for potential customers compared to aluminium. When coupled with the potential for lower energy costs is similarly significant to potential customers, particularly as prices for a lot of materials and energy are currently going up.
There is no definitive answer when it comes to deciding which is better. Aluminium is more expensive but has a much longer life span and provides an ultra-modern aesthetic to the home, potentially raising its value. On the other hand, uPVC has a lower life span but is an exceptional thermal insulator requiring low maintenance with a much lower price point.

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.

What is the history of timber windows and doors? While you might hear people talking about wooden windows and doors as being a ‘traditional’ option, you might not know why wooden windows and doors are the standard. It’s because, over the years, wood has been a reliable material for builders, architects and designers. Not only that, wood has been around and in use for several thousands of years, meaning the history of your windows goes much further back than you may know.
In this article, we’ll teach you about the history of timber windows and doors, and how that history has affected the modern designs you see today. Not only that, you’ll see the designs in a whole new light, and you’ll understand why features of timber windows and doors are the way they are. From there, we’ll see how modern wooden windows and doors are inspired by that history, but go in a new direction. As a result, you’ll get the full picture on timber windows and doors.
With Dempsey Dyer, you can get timber windows and doors that combine tradition and history with innovation and quality. Our timber windows and doors bring period style to your business’s product range, and they can also offer the high-end performance your customers need. Additionally, we can help homeowners find timber windows and doors for their properties, as well. If you’re interested, contact us today or start your trade quote.
We know that the history of timber windows and doors stretch back thousands of years. In fact, the earliest windows initially appeared in Alexandria, in Egypt at the time of the Roman Empire, around 100AD. However, that’s only when the wooden window had glass added to it, which is when it became a design that we would recognise today. However, the glass that was used was thick and opaque, meaning you couldn’t see very well out of them!
Wooden windows and doors are first defined in the 13th Century, and originates from the Old Norse phrase for wind-eye. Further on, timber sash windows were developed in the Netherlands in the late 17th Century, and these frames were constructed in a similar way than they are today. Beyond that, construction of timber windows and doors evolved with different varieties of wood being uses. Oak was the initial choice, but later mahogany and imported softwoods became more popular.
As a result, the story of timber windows and doors is thousands of years old, and the story has been changed by people from all over the world. Features like sash windows, sash pulleys, box frames and cornices have come and gone, and some of them have stood the test of time. So, if you have old wooden windows and doors in your home, you now may be able to see more of where they came from and how they came to be. Now, though, we’ll see where modern timber windows and doors are today.
Modern timber windows and doors take the best of old designs and marry them with the technology of new windows. Inspired by modern uPVC and aluminium windows as much as timber designs, new wooden windows and doors are more durable and more efficient. As a result, you can benefit from improved thermal performance inside your home with new wooden windows and doors. You’ll get advanced double glazing and more resistant profiles that create better insulation for your property.
Another benefit of modern timber windows and doors includes the range of designs you can now choose. Nowadays, companies all over the UK are coming up with unique ways to bring classic timber windows into the modern day for your home. You can find timber sash windows with traditional styles and features, but combined with modern features like advanced multi-point locking systems. Because of this, modern timber windows and doors are as secure and strong as they are stylish.
Even the type of wood in timber windows and doors is still evolving today. You can now get engineered timber profiles, meaning that the timber has been cleverly modified to make it more weather-resistant, meaning wind and rain won’t cause the same level of damage. As a result, you don’t have to regularly maintain modern timber windows and doors like people have had to do throughout history. Because of this, you can enjoy them without much less effort.
At Dempsey Dyer, we understand the history of timber windows and doors. Because of this, we know how to create a stunning set of modern timber windows and doors that still look timeless and storied. Our designs use a wide range of wood types, including engineered Accoya timber, and we fit them with both old features like detailed handles and new ones like advanced double and triple glazing.

Which window styles are the most sustainable? If you run a business, you might have noticed that your customers care a lot more about how the windows they install impact the environment. After all, our climate is becoming more of a hot topic, and global warming is something many businesses and consumers are looking to tackle. Fortunately, Dempsey Dyer is one of them – and, with our range of sustainable windows, we can make you one too.
At Dempsey Dyer, we can offer a wide range of sustainable window styles for your business. We can supply these windows directly to you or get them ready for you to pick up at our trade counter at a time that’s best for you.

As a result, all of our windows are thermally efficient, recyclable, and they can help your customers make a positive environmental impact.
With Dempsey Dyer, you’ll make your business more environmentally friendly, too. Our sustainable window styles last longer, meaning less waste, repairs and replacement for your team to deal with. And, as our windows are recyclable and highly durable, you can sell them to your customers as a long-term investment, making them more likely to choose you over your competition. So, if you’d like to find out which window styles are most sustainable, read on below or start your trade quote!
A crucial reason why some window styles are more sustainable than others is their glass. In older windows, only one pane of glass was the standard, which often wasn’t enough to prevent heat transfer from making homes cold and uncomfortable in winter and hot and stifling in summer. While most windows use double glazing these days, a standard unit doesn’t produce as much insulation as other options. Standard glass also isn’t as strong or durable as other types like annealed glass, meaning it’s more likely to break and need replacement.
Because of this, all of the window styles we offer to your business will have insulated glass. Insulated glass is brilliant at keeping cold air away and capturing the warm heat inside a building, producing less heat transfer. As a result, your customers can install our window styles knowing that they can stay warmer for longer, helping them save money on their energy bills and reducing their carbon footprint. We offer a wide range of glazing styles, and some of our units have argon gas to reduce heat transfer even further.
Another factor that makes some window styles more sustainable is the materials in the design. At Dempsey Dyer, though, we’ve created a range of uPVC, aluminium and high-quality timber windows that are all thermally efficient. Our uPVC range features Deceuninck profiles, among the market-leading options available today. As a result, our uPVC casement windows can achieve an A rating for thermal efficiency, meaning they offer brilliant insulation for homeowners.
We’ve also partnered with Reynaers to supply aluminium windows to your business that are thermally efficient. Although you might think aluminium isn’t an efficient material, we offer windows with thermally broken profiles that trap warm pockets of air, meaning they keep homes warmer for longer. Finally, our timber windows benefit from Accoya wood, a modified timber that is more resistant and durable than older wooden profiles. Accoya windows are also fully recyclable and produce no toxins during manufacturing, while the timber is always sustainably sourced.
Even the design of your windows can impact how sustainable they are. For example, flush sash windows have smaller gaps between the glazing and the frame, meaning there’s less space for cold air to get through. With our Stormproof windows, we’ve ensured that these gaps are draught-proof and won’t allow dampness to develop inside the space. As a result, you can offer your customers a window that’s not only thermally efficient but will be for years to come.
Finally, Dempsey Dyer can help if you have a customer who wants a window that meets specific requirements. It’s because we can react to custom orders, and we offer a wide range of glazing options, hardware and more to help them design their dream windows. You can place an order with us for any unique window and still benefit from the short lead times you want and the high standards we expect. No matter the windows you order from us, our window styles have sustainable design at their heart.
