If you’re looking to replace your old sash window with new frames, it’s expected you’ll have questions around materials, energy-efficiency, conservation areas and design options. We’ve answered some of our most commonly asked questions below. If you have any other questions our team will be happy to help, or you can visit your nearest design centre to see our window range for yourself.

What are sliding sash windows?

Sliding sash windows are a classic and versatile style of window commonly found in many traditional and historic buildings.

These windows consist of two vertically sliding panels or sashes. They were traditionally made of wood, though Joedan’s modern versions use UPVC. Each sash is counterbalanced by weights hidden within the window frame, allowing them to move up and down with ease.

Sash windows are known for their elegant and timeless appearance. They provide excellent ventilation control, as you can slide one or both sashes to adjust the airflow. Additionally, sash windows are popular for their ability to maintain the architectural integrity of older homes.

Today, modern versions of sliding sash windows are available at Joedan, with advanced features such as double glazing for improved energy efficiency and enhanced security measures. Their enduring charm and functionality continue to make them a popular choice for homeowners and architects alike.

How do you open sliding sash windows?

Joedan’s sash windows are simple to operate.

To open our sliding sash windows, begin by locating the discreet latch situated on the lower sash of the window. Gently lift or slide the latch, depending on its design, to release the sash.

Once unlocked, grasp the bottom sash and lift it upward, allowing it to smoothly glide along the vertical track. This motion permits you to control the ventilation as needed.

To close the window, simply reverse the process, ensuring the sash is firmly locked in place, preserving the aesthetics and functionality of these classic sliding sash windows.

How can I customise my sliding sash windows?

You can customise your Joedan sliding sash windows with our colour, hardware, and glazing options.

Customising your sliding sash windows allows you to add a personal touch and enhance the aesthetic appeal of your home.

You can choose from a wide range of coloured finishes to complement your home’s exterior or interior decor. Whether you prefer a classic white finish, a rich wood grain appearance, or a vibrant colour that stands out, there are options to suit your style.

Additionally, you can select from various glazing options, including decorative patterns, frosted glass, or energy-efficient double and triple glazing, which can improve insulation and reduce energy costs.

To complete the customisation, you can opt for our intricately crafted hardware, such as stylish handles and locks, to add both functionality and elegance to your sliding sash windows. These customisation options not only make your windows unique but also allow you to tailor them to your specific preferences and needs.

Are sliding sash windows suitable for conservation homes?

Sliding sash windows are often an ideal choice for conservation homes.

These classic windows, known for their timeless elegance, can seamlessly blend with the architectural styles of historic and conservation properties. Their traditional appearance closely mimics the original windows commonly found in such homes.

Conservation authorities and preservationists typically endorse sliding sash windows because they help maintain the historical character of the building. However, modern advancements in window technology now offer energy-efficient and durable options that meet contemporary standards while preserving the authentic look of the property.

Sliding sash windows are indeed suitable for conservation homes, effectively combining classic aesthetics with modern functionality while meeting the stringent requirements of historical preservation.
