When it comes to choosing windows for your home or commercial building, the two most common types you’ll likely come across are double-hung windows and casement windows. Each has its distinct advantages, so how do you know which one is the best fit for your needs? 

In this guide, we’ll compare double-hung windows vs casement windows in-depth, covering everything from installation costs and materials to ventilation and security features. 

By the end of this article, you’ll be well-equipped to make an informed decision about which window style works best for you.

Double-Hung Window vs Casement Window: A Quick Comparison

Double-Hung Window vs Casement Window: Which Is Better?

How Double-Hung Windows Work

Double-hung windows are designed with two sashes (the part of the window that holds the glass), which slide vertically. Both sashes can move up and down, allowing for optimal ventilation. This design is highly versatile and can be used in many property types, from traditional homes to modern flats.

How Casement Windows Work

Casement windows are hinged on one side and open outward, much like a door. These windows are known for offering excellent ventilation as they can open completely. They are commonly used in homes with modern aesthetics, where function and style are both crucial.

Which Property Types Are Best for Double-Hung & Casement Windows?

Best Properties for Double-Hung Windows

Double-hung windows are perfect for traditional or period properties, such as Victorian, Georgian, or Edwardian homes. Their classic design blends well with older architecture, making them ideal for homes that maintain a historical look.

Best Properties for Casement Windows

Casement windows are ideal for contemporary or modern homes. They can be fitted in both small and large spaces, and their clean lines make them a popular choice in minimalist designs. These windows also work well in areas where maximum ventilation is required, such as kitchens and bathrooms.

Double-Hung Window vs Casement Window Materials

Both double-hung windows and casement windows come in various materials, each offering its benefits. Below are the most common materials for each window type:

• uPVC: Affordable, energy-efficient, and low-maintenance. Commonly used for both double-hung and casement windows.
• Timber: Traditional material, offering excellent aesthetics and insulation properties, though requiring regular maintenance.
• Aluminium: Durable, sleek, and modern, but can be less energy-efficient unless thermally broken.

View & Natural Light Intake

Double-hung windows provide a relatively unrestricted view when open, but due to their design, they often only allow for partial opening. This limits the amount of natural light compared to casement windows, which fully open to let in maximum light and air. Casement windows are especially beneficial in spaces like kitchens, where ventilation is key.

Insulation & Energy Efficiency

Glazing Options

Triple glazing offers the best insulation, ensuring minimal heat loss and reduced energy costs. Casement windows, due to their tight seals when closed, tend to offer better energy efficiency compared to double-hung windows, particularly in colder climates.

Ventilation & Draughts

Ventilation: Casement windows provide superior ventilation because they can open fully, whereas double-hung windows offer only partial opening, limiting airflow. Casement windows also provide a better seal when closed, reducing the chance of draughts.

Security Features

Both window types come with advanced locking systems, though casement windows often have an advantage in terms of security. Their outward-opening design makes it difficult to access the locks from outside, providing an added layer of security.

Maintenance & Longevity

Both double-hung and casement windows require some maintenance, but double-hung windows are generally easier to clean due to their tilt-in sashes. Casement windows, however, require a little more care, particularly with the crank mechanism, which can wear over time.

Costs & Installation

The price of new windows depends on several factors, including the window size, type of material, glazing options, and the complexity of the installation. Below, we’ll compare the average prices of double-hung windows and casement windows:

While double-hung windows tend to be more affordable upfront, the cost of casement windows are generally higher due to their more complex mechanisms and better energy efficiency.

Installation Requirements & Timeframe

The installation of double-hung windows is generally quicker and simpler, especially if they are replacing existing windows. Casement windows, on the other hand, may require more time due to their complex mechanisms and the need for careful fitting.

Which is Best for Your Home: Double-Hung Window vs Casement Window?

When choosing between double-hung windows vs casement windows, it ultimately comes down to your preferences and requirements. If you want a classic, affordable option that is easy to maintain, double-hung windows may be the better choice. 

However, if you prioritise energy efficiency, ventilation, and modern aesthetics, casement windows offer significant benefits.

Comparing Double-Hung Windows to Other Window Types

When choosing windows for your home, it’s helpful to compare different styles to see which one best fits your needs. Here are some other window comparisons to consider:

Double-hung windows vs single hung windows – Both styles have a classic look, but single-hung windows have a fixed upper sash while double-hung windows allow both sashes to move. This affects ventilation, maintenance, and cost. If you’re trying to decide between the two, understanding these differences is key.

Double-hung window vs sliding window – While double-hung windows open vertically, sliding windows operate horizontally along a track. This difference impacts ease of use, airflow, and space considerations. Depending on your home’s layout and design preferences, one may be more practical than the other.
