Sash windows are the benchmark of period classic style.
Elegant and authentic, they will bring a unique look to any property.
You might not realise, however, that there are different types of sash windows available.
Or maybe you do know and you’re just struggling to choose.
Whatever the reason, we’ve put together this short guide to give you some more information.
What are sash windows?
Before we get started, let’s take a second to understand what we mean when we talk about sash windows.
A sash window is constructed from two sashes, and a sash is the frame with the glass inside.
The two sashes sit in front of each other, and the front sash will slide up and down to open the window.
Sash windows will generally feature sash horns, concealed trickle vents, moulded lamb tongue profiles, and staff beads that are internally moulded.
Sash windows can be designed for lead weights with nylon chords, which is the most traditional and classic. They can be made more modern with a spring-balanced window that is pre-tensioned.
Timber sash windows
Sash windows with a timber frame are the most classic. They suit traditional homes in conservation areas or listed buildings.
Box or spring-balanced sash windows
Box sash windows combine classic style and modern technology, using pulleys, weights, and cords to balance the bottom and top sashes.
The weights are inside a box that is made by liners on each side of the frame.
If you want a traditional style that still has high security and benefits from high thermal and acoustic performance, choose box sash windows.
Spring-balanced sash windows are a modern alternative to box sash windows – they use a mechanism that is spring-loaded instead of classic cords, weights, and pulleys.
You’ll often find these types of sash windows on new-builds properties.
Glazing for sash windows
Many people seem to have the idea that sash windows can’t be double or triple glazed because they are so traditional.
This is not true.
The best depth for sash windows sits at 68mm, which allows for double and triple glazing.
It’s always best to choose double or triple glazing for the completely superior energy efficiency and sound reduction.
Legacy sash windows
People who have very old sash windows that are single glazed and let in draughts often choose legacy double glazed sash designs.
These are similar to classic sash windows but have thinner frames and sash and glass sections.
