What Are Vertical Sliding Windows Or Hung Windows?

Vertical sliding windows or hanging windows are a type of window design that can slide open from top to bottom or bottom to top, effectively regulating ventilation and light entry. This type of window usually has two moving parts, making it easy to clean and maintain, and suitable for small spaces or situations that require frequent opening and closing.

Types Of Hung Windows

The following are the three types of sliding windows:

  • Single hung windows: These have two sashes, with the upper sash fixed while the lower one moves up and down within the frame to adjust the window opening.

  • Double hung windows: Featuring two sliding sashes within the same frame, they can tilt for easier cleaning.

  • Three lite windows: Typically found in bow and bay window setups, these windows have multiple sliders on each side.

Among these vertical hung window types, Double Hung Windows are the most commonly chosen for homes. They are frequently used in various spaces such as living rooms, bedrooms, bathrooms, kitchens, and dining rooms. These windows are crafted with durable and low-maintenance materials like aluminum and uPVC frames, providing longevity compared to wooden frames.

What Are Horizontal Sliding Windows Or Slider Windows?

Horizontal sliding windows, also referred to as Slider windows, offer a unique functionality where their sashes slide from side to side rather than the traditional up-and-down movement seen in other window types. This design makes them an ideal choice for wider openings, allowing for a seamless fit into expansive spaces. Their adaptability in sizing enables them to be tailored precisely to the required dimensions. We provide a selection of top-notch aluminum sliding windows, showcasing our 50, 80 series and the 90 sliding windows series. These windows are crafted to deliver outstanding durability and visual appeal.

One notable advantage of Slider windows is their ease of operation – they're simpler to open and close compared to Hung windows, making them an excellent option for households where ease of use is a priority, especially for individuals with limited mobility. Their operation often mirrors that of a patio door, smoothly gliding along the track when opened.

These windows come in various sizes, from compact to larger formats, catering to diverse architectural needs. There are typically two types within horizontal sliders: single sliding sash windows, where one panel moves, and double slider windows, where both panels slide.

Horizontal sliding windows find wide application in various residential spaces like living rooms, bedrooms, bathrooms, kitchens, and dining rooms. Their contemporary design not only adds a modern touch to interiors but also allows for an increased influx of natural light, creating brighter and more inviting spaces. Beyond residential use, they are also commonly employed in commercial settings such as office complexes and retail buildings due to their functionality, aesthetic appeal, and capacity to enhance natural lighting within these spaces.

What Is The Functional Difference Between Double-Hung Windows And Vertical Sliding Windows ?

Both types of sliding windows work on basically the same principle, which is sliding. The biggest difference between them is how they open. Double-hung windows open from the top or bottom, while sash windows slide horizontally.

Another difference between the two is how they are installed. Hanging windows require additional hardware such as pulleys, weights, and springs to function properly, while sliding windows do not. This makes them easier to install than other types of windows and often less expensive.

Design choices make a big difference when it comes to ventilation – depending on your needs, you may want to choose one type of window over another.

Pros And Cons Of Both Double Hung Windows And Horizontal Windows

When deciding on the ideal window type for your home, weighing the benefits and drawbacks of each option is crucial.

Pros Of Double/Single Hung Windows:

Ease of Cleaning: One of the standout advantages of vertically hung windows is the convenience they offer during cleaning. Their design allows for easy access to both the interior and exterior surfaces. Whether it's the top or bottom sash, you can effortlessly open them to reach and clean the glass with a duster or sponge. This eliminates the hassle of reaching or struggling with difficult angles that some other window types present.

Enhanced Ventilation Control: Compared to slider windows, hung windows provide superior control over ventilation. With double-hung windows, for instance, the dual sashes can be adjusted separately, allowing for precise regulation of airflow. This flexibility enables you to tailor the opening of the windows at different levels, optimizing ventilation according to your preferences and the surrounding conditions.

Timeless Aesthetic Appeal: The traditional design of single and double-hung windows makes them a timeless choice for homes. Their classic appearance seamlessly integrates with various architectural styles, offering a versatile option for homeowners. Available in an array of shapes, sizes, and colors, these windows can be tailored to complement and enhance the aesthetic appeal of any home.

Cost-Effectiveness: In terms of affordability, hung windows generally prove to be a more economical choice compared to other window types. For instance, a single hung window typically ranges from $140 to $400, whereas sliding windows can cost between $415 and $890. This cost difference can make hung windows a more budget-friendly option for those looking to upgrade their windows without breaking the bank.

Space Efficiency Over Casement Windows: Unlike casement windows that swing outwards, often requiring ample space, single and double-hung windows open vertically, utilizing minimal space when opened. This characteristic makes them an ideal choice for areas where space is limited or where outward swinging windows might not be practical.

Cons Of Vertical/Hung Windows:

Complex Installation Requirements: Unlike some other window types, the installation of hung windows can be more intricate. These windows necessitate additional hardware for proper operation, such as weights and pulleys, and often demand professional expertise for correct installation. For DIY enthusiasts, attempting to install hung windows without the necessary experience and tools is not recommended due to the complexity involved.

Risk of Accidental Falls: One notable drawback of hung windows is their susceptibility to falling shut. The weight of these windows can lead to sudden closure, posing a potential hazard, especially if not properly maintained. Over time, wear and tear can displace or disconnect the balance shoes, leading to the window unexpectedly dropping, which can cause injury or damage.

Lower Energy Efficiency: The traditional design of hung windows may compromise energy efficiency. The construction of these windows can create air gaps between the sashes, which can allow air to escape, impacting the overall insulation of the window. Consequently, this reduced insulation may result in higher energy consumption for heating or cooling as the windows may struggle to maintain an optimal indoor temperature.

Accessibility Challenges: The design of hung windows can present difficulties for individuals with limited mobility. Operating these windows, particularly opening and closing, might be challenging for those who face mobility issues. The vertical movement required to adjust these windows may prove cumbersome or inaccessible for certain individuals, potentially limiting their ease of use within a home.

Pros of Horizontal Sliding Windows:

Ease of Installation: Installing horizontal sliding windows is notably simpler compared to some other window types. These windows typically do not require additional hardware for operation, making the installation process straightforward. Even individuals with basic DIY skills can manage to install them without much difficulty.

Ease of Operation: One of the standout advantages of horizontal sliding windows is their effortless operability. Their smooth sliding mechanism makes them exceptionally easy to open and close. This ease of use is particularly beneficial for households with individuals who have limited mobility, providing convenience and accessibility.

Aesthetics and Variety: Horizontal sliding windows come in a diverse range of styles and designs, allowing homeowners to select the perfect window that complements their home's aesthetic. This versatility in design enables these windows to seamlessly integrate with various architectural styles, enhancing the visual appeal of the property.

Enhanced Ventilation: These windows boast larger openings compared to some other window types, facilitating superior airflow into a room. This feature promotes better ventilation, allowing for a fresher and more comfortable indoor environment.

Modern Design Aesthetics: The clean, sleek lines of horizontal sliding windows contribute to a contemporary and modern look for homes. Their minimalist design adds a touch of sophistication to the overall appearance of the property.

Wide Range of Sizes: Horizontal sliding windows are available in a broad spectrum of sizes, catering to both small and large openings. This versatility makes them a suitable choice for various spaces within a home.

Cost-Effectiveness: Sliding windows typically offer a more budget-friendly solution compared to hung windows due to their simpler hardware design. This affordability makes them an attractive option for homeowners looking for efficient yet economical window choices.

Cons of Horizontal Sliding Windows:

Space Requirements: Unlike some other window types, horizontal sliding windows necessitate space on both sides for installation. This space requirement might limit their practicality for narrow spaces or areas where the availability of lateral space is restricted.

Airtightness and Insulation: The simpler hardware system of sliding windows might result in comparatively poorer airtightness and heat insulation capabilities. This can lead to reduced thermal efficiency compared to windows with more intricate sealing mechanisms, potentially impacting the indoor climate control and energy efficiency of a home.

Factors To Consider When Choosing Between The double hung windows and horizontal sliding windows

Deciding between double hung windows and horizontal sliding windows for your home involves considering several factors that will guide you toward the more suitable option for your needs. These factors play a crucial role in making the right choice.


Double-hung windows generally require more space above and below to open because they move inward or outward. If space is limited, transverse sliding windows may be a better option as they only slide horizontally and do not take up additional indoor or outdoor space.


Double-hung windows offer more flexible ventilation options as they can be opened from both the top and bottom at the same time, promoting air circulation. Lateral sliding windows can usually only be opened from one side, limiting air flow, especially if only one side can be opened.


Budget is an important consideration. Typically, double-hung windows can be slightly more expensive because they may require more workmanship and materials to manufacture and install. In contrast, transverse sliding windows may be more cost-effective.


Your geographical location is also important. If you live in an area with a milder climate, there are usually more ventilation options to consider. For example, warmer climates may make double-hung windows more attractive because they provide more space for ventilation.

Window style:

Finally, your personal preferences and overall home style are also deciding factors. Double-hung windows may be more suitable for traditional or classic style buildings, while transverse sliding windows are generally more suitable for modern building designs.

Which One You Should Choose – Vertical Or Sliding Window?

The decision between vertical and sliding windows relies on individual needs and preferences. Considerations such as size, budget, ventilation, window styles, and installation play key roles in determining the ideal window type for your home. For instance, if you seek convenient access and ample ventilation, double-hung windows might suit you better. Yet, if you prioritize airflow control and have mobility constraints, sliding windows could be a superior choice. Ultimately, the best window type for your home is a decision you'll make based on your unique requirements.
