What Are Windows Sashes?

Windows sashes are windows that consist of one or more movable panels, known as ‘sashes’, that can often be found in traditional-style buildings.

These sashes usually contain either paned glass or a single sheet of glass and are designed to open, close, and slide within the window frame.

The sash window is an attractive feature in many homes due to its aesthetic value as well as its practicality, allowing for natural light and airflow whilst maintaining security and privacy.

Why Are Windows Called Sashes?

Windows are called sashes because they consist of a frame made up of several movable panels, known as sashes. This frame holds panes of glass together and is operated by sliding the sash open vertically or horizontally, hence the name sash windows.

Astragal bars further divide the panes of glass for an improved visual appeal. Sash windows are commonly used in traditional buildings for their classic design and are also seen in contemporary structures for their ease of use and improved ventilation capabilities.

How Many Sashes Does A Window Have?

Windows typically have two sashes – frames that contain the glass panes. These are moveable so you can open the window and allow air to circulate, as well as control how much light comes into the room.

Additionally, the sashes allow for easy cleaning of your windows both inside and out. The number of sashes a window has depends on its size and design: for example, casement windows may have only one, while some larger bay windows might have three or more.

What Is The Difference Between A Window Frame And A Sash?

The difference between a window frame and sash lies in their construction; the frame is the external part of the window which is fitted to the opening in the wall, while the sash is the moveable panel that fits inside it.

The frame holds and supports the sash, and glass panels are then inserted into it for insulation. Poorly designed windows can be a cause of heat loss, so it’s important to ensure each component (frame and sash) are correctly constructed to prevent energy leakage.

What Are The Different Types Of Sash Windows?

Sash windows come in three basic designs: Georgian, Victorian, and Edwardian.

Georgian sash windows have six panes in their frames arranged “six over six”, while Victorian feature grids of two panes each arranged with a “two over two” design.

The third type is the Edwardian style which has panes arranged in a “six over two” pattern.

Depending on the period your home was built in, you may opt for one style or another depending on what looks best aesthetically – although all styles look elegant and can add an air of sophistication to your home.

What Are The Benefits Of Sash Windows?

Sash windows are perfect for homes looking for low-maintenance, durable windows. Unlike wooden frames which require regular sanding and varnishing to prevent warping and rot, sash frames made of metal or plastic do not require any such treatment.

They can be installed in hard-to-reach places without worry about deterioration due to weather or age.

Additionally, sash windows provide a traditional aesthetic with modern dependability that is sure to stand the test of time and last you many years with virtually no maintenance required.

What Materials Are Sashes Made Of?

Window sashes come in a variety of materials, the three most common being wood, aluminum and vinyl.

Wooden sashes are aesthetically pleasing, often chosen for their traditional look and feel. Aluminum is durable, lightweight and rust-resistant making it a good choice for areas exposed to the elements.

Vinyl is energy efficient and provides superior insulation with low maintenance requirements. Each material has unique advantages, so when choosing a window sash material consider your home’s existing style as well as your budget.
