Which Windows Are Most Energy Efficient?

Introduction

At Dempsey Dyer, we supply and install a variety of windows for your customers’ property, so it is important to understand which windows are best for energy efficiency, as they will be able to stay warm. In this article, we will go through a list of windows to look at which one is right for you. Read on to find out more.

Double Hung Windows

Double hung windows are an extremely common type of window and are generally the most energy efficient. They make it easy to control ventilation and light in different rooms. These windows have two sashes that slide up and down independently of each other, providing a great way to control the airflow in any room. The sashes are typically made of a sturdy material such as vinyl or fiberglass. They feature a tight seal that helps keep drafts out. It’s important to make sure the side of the window that doesn’t open is properly sealed to maximize the window’s energy efficiency.

Casement Windows

 Casement windows are another energy efficient option, offering excellent ventilation and light control. This type of window hinged on one side, and swings open from the side to provide an unobstructed opening. The tight seal around the window frame also helps to keep out drafts. Casement windows come in a variety of styles, including single- and double-hung, awning, and hopper. For maximum efficiency, choose a style with low U Values, which measure how much heat is lost through the window.

Sliding  Sash Windows

Sliding sash windows are just as energy efficient as double hung and casement windows. These offer excellent insulation, as the tight seal between the window frame and the window keeps drafts out. Sliding sash  windows feature two sashes that slide side to side, allowing you to control the amount of light and air entering a room.

Fixed Windows

Finally, fixed windows are an excellent choice for providing natural light and ventilation without compromising energy efficiency.  These windows come with advanced double glazing, so let your customer know that they will receive high levels of energy efficiency when they are properly installed. This way, their energy bills will be saved over time.

Make sure you hire a qualified installer to secure your windows correctly to ensure they remain energy efficient. With the right windows and proper installation, you’ll enjoy significant savings in energy bills and improved home comfort, all while reducing your environmental impact.

Double and Triple Glazed Windows

One of the best ways to improve a window’s energy efficiency is to upgrade to double- or triple-glazed windows. These windows use multiple layers of sealed glass panes to trap heat and cold air inside the home, reducing the amount of energy needed to keep the space warm. While double- and triple-pane windows are expensive compared to single glazed windows, they save money on energy bills in the long term.

Tilt & Turn Windows 

Tilt and Turn windows come in a wide selection of energy efficient glazing patterns. This will help give your customer plenty of customisation options that will ensure you have low thermal efficiency values. As a result, your customer will get plenty of privacy and customisation options.

Fiberglass Windows

Fiberglass windows are also energy efficient due to their ability to absorb and reflect heat from the sun. The material also provides superior insulation, helping to keep your home cooler in the summer and warmer in the winter, reducing your need for heating and cooling. While more expensive than other window types, fibreglass windows can pay for themselves over time through energy savings.

Storm Windows

Storm windows are an additional layer of windows that are installed over existing windows. These windows are designed to protect against wind, rain, and debris while also providing additional thermal resistance. Installing storm windows can significantly reduce heat loss during the winter and can also reduce heat gain during the summer.

Conclusion

We hope that this article has helped you understand which windows are the most energy efficient. Ultimately, the choice depends on the climate and specific needs of your home.

Double- and triple-glazed windows, low-E windows, fibreglass windows, and storm windows are all great options for improving your home’s energy efficiency. Investing in higher quality windows now helps you save money on your energy bills in the long run and reduce your home’s environmental impact.

Aluminium vs Timber Windows – Which Is More Sustainable?

Introduction

At Dempsey Dyer, we supply aluminium and timber windows to the trade. Both these windows have many benefits for your customer, including thermal efficiency. This is supported by advanced double glazing which has a polyamide thermal break. Inform your customers that this retains  heat inside their home.

In this article, we will explain which windows are more thermally efficient. Read on to find out more.

How sustainable are aluminium windows?

Choosing aluminium windows could be ideal when it comes to sustainability. Aluminium is a much lighter material than timber, so less energy is required in the production process. In addition, the majority of aluminium used in manufacturing the windows can be recycled, which reduces waste. The windows are low maintenance, which only requires a simple wash and it looks as good as new.

Aluminium is supported by advanced double or triple glazed windows. These panes create a robust thermal barrier that retains natural heat inside your customers’ home. Inform your customer that this is a unique selling point because it helps naturally save money on their energy bills, which is imperative in a cost of living crisis. This is essential in the winter months when energy prices rise.

Aluminium windows are thermally efficient

Aluminium is thermally efficient, retaining heat inside your customers’ homes, saving money on energy bills. When it reaches the end of its lifespan, it can be recycled into something new. As one of the most used materials in the world, it is lightweight, sturdy, and easy to handle. This means when you transport the windows, the costs will be reduced.

Your aluminium frames are designed to resist heat loss, helping keep your home warmer in the winter and cooler in the summer. This not only helps to reduce your energy bills but can also have a positive impact on your carbon footprint.

Aluminium Does Less Damage to the Environment

Inform your customer that aluminium is ideal for the environment in comparison to timber. When new homes are built, builders are more likely to use aluminium over timber to reduce deforestation properties. Aluminium is a low maintenance material in comparison to timber, ensuring it is easy to wipe down.

Timber Windows Reduce Energy Use Naturally

The wood fibres used in timber windows  to make the frames are taken from sources, making them a more environmentally friendly option than aluminium. In addition, the natural insulating properties of wood help to reduce energy use, both in production and in your home, as timber naturally retains heat better than aluminium. When choosing timber windows, it’s important to find a product that is FSC certified, as this ensures that the timber has been sourced in a responsible manner. Inform your customer that this is an ideal choice to boost the environment.

Timber Windows Create Energy to be Used In Buildings

Inform your customer that if they use timber to create a sustainable build, then they will be able to keep heat in their home. Timber is a naturally sourced material, which reduces your customers’ carbon footprint in a building.

It is a popular material continues to be grown all over the world. The embodied energy of timber is low, ensuring it is an environmentally responsible option in comparison to more polluting alternatives. In fact, timber can be built at a faster and lower cost, making it affordable for customers who are on a budget.

Timber is a Popular Builders’ Choice

Similarly, to aluminium, timber is a lightweight material, ensuring that it is a popular choice for builders. It is a sustainable choice for the environment because it offers acoustic benefits as well. It is a strong insulator of sound, being able to cut loud noises out. As a result, let your customer know that they will enjoy a peaceful environment.

Conclusion

We hope that this article has helped you understand how thermally efficient aluminium and timber windows are. At Dempsey Dyer, we source windows from both materials, so ultimately the choice is up to you.

If you’re looking for a longer-term investment, with less maintenance, then aluminium windows could be the better option. However, if you’re looking for something that is more environmentally friendly, then timber windows could be a suitable choice.

Introduction

At Dempsey Dyer, we supply and install windows and doors for the trade. If your customer lives in a traditional property, an upgraded window adds plenty of character to their home. If you are looking to learn more, get in touch with us today.

When it comes to windows, the traditional style requires that they maintain symmetry. Try to match the existing window sizes, shapes, and materials as closely as possible. Sticking with wooden frames can help keep the traditional look alive, but vinyl frames are also a popular choice for durability and cost. Look for windows that feature sashes made of wood, wood-clad, or vinyl.

What Are Traditional Windows and Doors Made From?

Traditional-style windows will include muntins or grids, which refer to the interior panels in a window. If you’re looking for complete authenticity, arched or patterned glass designs can enhance the historic look further. As for doors, the designs should reflect the style of the architecture and create a unified look. Whether you choose wood, wood-clad, or fibreglass, the door should match the rest of the home’s facade. Don’t overlook the hardware, be sure to find finishes that will enhance the door’s primary style. If you’d like to capture a more classic look, choose a six-panel wood door with an arched or keyhole window.

How to Achieve a Modern Look or Your Traditional Home

 If you’re striving to go for a modern look, opt for a fibreglass door with a sleek design and contemporary hardware. If you’re wanting to add a traditional look to your home, one of the best ways to do this is by carefully choosing your windows and doors. Making sure the windows maintain symmetry is key – try to find windows that are a close match to the existing size, shape, and material of your home’s architecture.

Wooden window frames are popular for a traditional look, but Vinyl can also be used for its durability and affordability. When choosing a door, the design should be complementary to the existing style of the home and create a consistent look. Make sure the material – such as wood, wood-clad, or fibreglass – matches the facade of the home. The hardware plays a big part in the overall aesthetic too – find finishes that will best enhance the door’s primary style to achieve the right look. If you’d like a classic or vintage look, opt for a six-panel wood door with an arched or keyhole window.

Which Traditional Style Doors Are Popular


For traditional-style doors, you’ll want to consider panels, designs, and hardware that are authentic to the era. Wooden doors usually require careful attention and maintenance, but their durability and classic look is worth the upkeep. Try to match the exterior door to the architectural style of the home. Traditional-style doors may have simple glazing patterns or multi-pane glass designs.

Inform your customer that composite doors are a popular design for your home. If your customer is looking for a modern design for their home, composite doors provide the best of both aluminium and uPVC, alongside a robust thermal core. Inform your customers that they will be kept safe for many years to come.

Another door that is useful for traditional properties is a stable door. Inform your customers that this is a useful back door that offers the best of both worlds. Your customer will get a rustic country charm alongside fantastic security. This is a unique selling point as intruders will be warded off easily. A stable door includes an opening that lets in plenty of natural light, so your customers will save money on their energy bills. And, it will make their home brighter, increasing their market value as a result.

What Hardware is Available for Traditional Doors?

Additionally, period hardware is available in many forms, including latch sets, handles, door knobs, and hinges. These may also be made of brass, iron, bronze, steel, or pewter to really capture the period style of the house.

We offer these hardware designs in a range of styles, giving you plenty of choice. Consider a woodgrain finish, which gives you the modern benefits of uPVC alongside a natural look. 

Conclusion

We believe that ultimately, whether you go for a modern or traditional look, the choice should be up to you. At Dempsey Dyer, we have years of experience when it comes to installing timber windows in your property.
