Key Takeaways

• Top-hung windows are a popular and affordable choice for homeowners due to their versatility and durability.
• Size is a key factor in determining the overall cost of these windows, and readers will learn how to find the best deals on installation.

What is a Top Hung Window?

A top hung window, also known as an awning window, is a single window unit that is attached to its frame by a top hinge. Unlike side-hung uPVC casement windows, which are attached by a side-mounted hinge, top-hung windows open from the bottom. These windows can either be free-standing single units or fitted alongside fixed windows to provide ventilation. They are also commonly placed above doors or in high-up places.

Why Use Top Hung uPVC Windows?

Top-hung uPVC windows are versatile and come in smaller sizes, which makes them suitable for window placement in areas that may not be available otherwise. They offer several benefits, such as:

Smaller Sizes
Top-hung windows come in a variety of sizes, with the smallest ones being 350mm in height and 380mm in width. These dimensions give homeowners more options as to where they might place the windows in their homes. They are commonly found as single units in small rooms, closets, or WCs where natural ventilation is more needed than light transmission.

Hard-to-Reach Spots
Top-hung windows are commonly placed in high-up places, such as basement rooms or basement apartments that need some natural light and ventilation. They are easier to operate than other window types that open from the centre, and there are mechanisms available to make high-up window operation much easier.

Top-hung windows placed in high or low places are harder to see through from outside the house, making them a great option for bathrooms or WCs.

Benefits of uPVC
Choosing uPVC as the material for top-hung windows brings a range of benefits compared to other materials. uPVC is one of the most affordable options, generally running lower than aluminium and timber by up to 30% and 80%, respectively. uPVC windows are durable and can last up to 25 years. They are also eco-friendly and require little maintenance.

What is the Cost of uPVC Top Hung Windows?

Top-hung windows are generally one of the cheapest traditional window types in the UK. Compared to uPVC casement window costs, they might be 10% lower and as much as 60% lower than uPVC tilt-and-turn windows. Compared to sash windows, one of the more expensive options out there, you can expect to pay less than half for standard-sized top-hung windows in uPVC.

The cost of uPVC top-hung windows depends on the size and ranges from £160 to £825 for standard sizes. However, other factors such as installation costs can influence the overall cost. It is important to get quotes from local installers to ensure you are receiving a fair deal tailored to your home’s exact specifications.

Selecting the Top Hung uPVC Windows

Can Double Glazed Windows Be Used with Top Hung uPVC Frames?

Double glazed windows can be used with top hung uPVC frames. Double glazing is highly recommended for energy efficiency, as it prevents excessive heat from escaping the home during the winter months and helps keep the home cool during the summer. In fact, double glazed windows have become the standard in the UK to meet minimum efficiency regulations. Single glazing tends to have a higher U-Value, which means it allows more heat to escape. Triple glazing is even more thermally efficient, secure, and durable, but it comes at a higher cost than standard double-glazed windows.

What is the Maximum Size of a Top Hung uPVC Window?

Top hung uPVC windows are available in a variety of sizes, from small to large. While they are well-suited for smaller windows, they can also be used for larger windows. The average uPVC window measures 1,200mm in height and 1,200mm in width. The maximum size of a uPVC top-hung window is 1,500mm x 1,500mm in height and width, respectively. Large top hung uPVC windows can have a stunning visual impact, especially when paired with slim black uPVC frames that give a luxurious and modern appeal.

When selecting the best top hung windows, it’s important to consider the size of the window and how it will fit in with the surrounding space. Top hung windows can be placed by themselves in smaller spaces, or in a group of windows where there is ample wall space. They can also be paired with fixed windows that don’t open to provide ventilation. Additionally, coloured uPVC windows are available in a variety of colours, from bright to neutral to pastel, allowing homeowners to choose a colour that enhances the visual impact of their windows and matches their desired aesthetic.

When it comes to glazing options, low-E glass is an excellent choice for energy efficiency, as it has an ultra-thin coating that prevents heat from passing through it. Tinted glass is a good option for privacy, as it prevents people from seeing through the window from the outside. Decorative glass is also a great way to add a design to the glass while maintaining privacy. There are many customisable decorative glass designs available, depending on the manufacturer.

In summary, selecting the best top hung uPVC windows involves considering the size of the window, the surrounding space, and the homeowner’s desired aesthetic. Double glazed windows are highly recommended for energy efficiency, and low-E glass is an excellent choice for this purpose. Tinted glass is a good option for privacy, and decorative glass adds a design element while maintaining privacy. Coloured uPVC windows are available in a variety of colours to match any aesthetic.
