What are sash windows & should you get them?

Osborn Windows > News > What are sash windows & should you get them?

Sash windows have been a popular choice for homeowners for centuries, thanks to their elegant design and versatility. Whether you are looking for a traditional or contemporary look, sash windows can be customised to suit the needs of your home. Here’s everything you need to know about sash windows to help you make an informed decision about whether they are right for your home.

What are sash windows?

Sash windows are windows that consist of two panels, known as sashes, that slide vertically up and down to open and close. They were first used in the 1600s and became popular in the Georgian and Victorian eras. Sash windows are commonly made from wood or PVC, and can be finished in a variety of colours and styles to match the decor of your home.

What’s good about sash windows?

Excellent ventilation 

There are many great reasons to choose sash windows for your home. One of the biggest advantages is that they provide excellent ventilation. With the ability to open both the top and bottom sashes, you can easily control the amount of fresh air that enters your home. This helps to keep it cool in the summer and reduces condensation in the winter.

Low energy bills

Another advantage of sash windows is that they are energy efficient. Many modern sash windows come with double glazing, which helps to insulate your home and reduce heat loss. This can lead to lower energy bills and a more comfortable living environment.


Sash windows are also very versatile and can be customized to suit the needs of your home. For example, they can be made to open outwards, making it easier to clean the outside of the windows. They can also be fitted with a range of security features, such as locks, to help keep your home secure.

The issue with sash windows

May be more expensive 

One of the main disadvantages of sash windows is that they can be more expensive than other types of windows. This is because they are often made from higher-quality materials and require more skilled labour to install.

While there may be a relatively high upfront cost, with proper maintenance, sash windows can last for many years and save you money in the long run due to their energy-efficient properties. 

Difficult to clean

Another disadvantage of sash windows is that they can be difficult to clean, especially if they are located in hard-to-reach areas. This is why it’s important to choose windows with a good locking mechanism so that you can easily clean both the inside and outside of the windows.

Maintaining sash windows

Sash windows require regular maintenance to keep them looking and functioning at their best. This includes cleaning the windows, oiling the hinges, and checking the seals to ensure that they are still in good condition.

It’s also important to have your sash windows serviced regularly by a professional. This will help to identify any problems early on so that they can be fixed before they become more serious.
