Sliding Sash vs Flush Casement Windows – Which One Is Right for You?

When it comes to deciding on a new window for your home, you need to consider all of your options. Sliding sash and flush casement windows are two of the most popular styles, and each has its own set of pros, cons and uses. Before making a decision, it’s important to understand the differences between the two, and how they can affect your home.

When choosing the perfect windows for your home, we understand a few factors you will be considering, including energy efficiency. Winter has come in full force and with rising energy costs making a significant impact on families’ household budgets, changing your windows to improve their energy efficiency rating could really help save those pounds. 

That’s why, we at Genesis have created this useful guide to sliding sash and flush casement windows, so you can decide which one is right for your home. We’ll also discuss the important energy efficiency and aesthetic differences between the two types of windows, so you can make the most informed decision. 

So, let’s dive in and see which window is best for your home.

What are Sliding Sash Windows?

Sliding sash windows are one of the oldest and most traditional types of windows. Our Sliding Sash windows are made of uPVC, which often gets mistaken for timber as they look very authentic, thanks to the woodgrain finish and traditional joinery methods. If you have an older home, odds are that you have at least a few sliding sash windows that are in a state of disrepair, as they were very common during the Victorian era. 

Sliding sash windows are traditionally left partially open, with the top portion lowered to allow airflow. In addition to the aesthetic value that this type of window offers, sliding sash windows also provide some acoustic insulation.

Sliding Sash Materials 

These windows are typically made with a very heavy wood frame and come with a single pane of glass. However, our modern Sliding Sash Windows are created using modern materials that provide a realistic alternative to timber, which seamlessly combines the elegance and style of conventional sash windows with energy-saving properties. Our Sliding Sash windows also provide high-security, and low-maintenance advantages provided by contemporary materials and manufacturing techniques. 

What are Flush Casement Windows?

Flush casement windows are a type of hinged window that can be found in both period homes and new construction. The most notable difference between a sliding sash window and a flush casement window is how they open. Instead of sliding, a flush casement window pivots outward and can be top or side hinged. 

Flush Casement Materials 

Our uPVC Flush Casement Windows blend traditional styling with cutting-edge technology to create the symmetrical, flush-face form of the Genesis Flush traditional window, adding harmony and balance to any home.

Pros and Cons of Sliding Sash Windows

Sliding sash windows are beautiful, but they’re not the best option for every homeowner.

Let’s go through some of the pros and cons:

  • If you live in a very cold area, a traditional sliding sash window may not be the best choice as they are known for not being very well insulated. However, due to Genesis upgrading traditional Sliding Sash Windows, you need not be concerned.

  • If you’re looking for a window that’s easy to clean and low maintenance, then Sliding Sash Windows are a great option.

  • Sliding Sash Windows are perfect for providing a vintage look to any home and are perfect for renovations to period properties. 

Pros and Cons of Flush Casement Windows

Flush casement windows are a great choice for most homeowners but let’s take a look and see if they are the right fit for your home. 

  • Flush Casement windows provide amazing insulation and energy efficiency, make sure to check out our energy efficiency ratings here.

  • They’re easier to clean, which is a big bonus for many homeowners.
     
  • Flush casement windows are simple to use, making them easy to open and close, even with one hand.

Energy Efficiency of Sliding Sash and Flush Casement Windows

Both sliding sash windows and flush casement windows provide excellent energy efficiency, so this isn’t a deciding factor for most homeowners. All of our windows are typically made with high-performance double-glazed units. This makes them great for areas with cold winters, as it helps to retain heat inside your home. 

Aesthetics of Sliding Sash and Flush Casement Windows

The aesthetics of a sliding sash window and a flush casement window vary depending on the style of each window. A traditional sliding sash window will add an old-fashioned charm to your home, while a flush casement window comes in a variety of modern styles, some new, some more period. 

Typically, if you’re looking to maintain an old-fashioned aesthetic in your home, a sliding sash window is a great option. Our Genesis Sliding Sash Windows come in a variety of options, so you can find the perfect fit for your home, traditional or modern. 

If you’re looking for a modern aesthetic, a flush casement window is a solution. Getting the ideal Flush Casement Windows could not be simpler as you get to choose from a selection of different layout sizes and colours.
