Vertical-sliding sash windows can have numerous advantages that set them apart from other window types, offering all the benefits of a secure window design and several major tweaks and additional features. In most homes, they are the quintessential window choice.

Many people who have been thinking about vertical sliding sash windows will be focusing on a particular detail, like the changes in design or the more straightforward opening mechanism. However, we construct all of our sash windows to offer a combination of excellent quality and all the benefits of a normal design initiative.

The rapid increase in installed period character sash options hasn’t come from nowhere. On the contrary, this rapid increase in recent years is precisely because these windows are so well-liked.

We offer a wide range of sash window options that can easily fit into your home. Whether it is modern vertical-slider windows or more traditional sash windows that have been updated with today’s modern security features, we can provide the right replacement windows for your home.

What is a Sash Window?

Sash windows are vertical slider windows generally made with two framed panels, one sliding up over the other. Instead of swinging away from the frame, these windows can be slid open and locked, minimising their space usage.

Our modern vertical slider windows boast the same advantages as the moveable sashes in traditional housing, enabling homeowners to save money on energy bills, increase their home security, and retain heat for longer. All of our moveable sashes are designed for the best possible results at all times.

How do Sash Windows Work?

Vertical sliding sash windows have two frames: the stationary pane and only one moveable pane. A pulley system allows the moveable pane to be opened by lifting upwards rather than swinging outwards like some other modern windows.

Most vertical sliding sash windows are designed to be subtle, so the mechanisms to get the moveable pane lifting upwards is not immediately visible. Our windows are designed with a concealed internal mechanism, enabling homeowners to install moveable sashes without compromising their traditional housing style and atmosphere.

Sash Window Costs

The cost of installing new vertical sliding sash windows (or installing them as replacement windows) depends on the property’s age, the size and style of the window, and the kind of glazing you want. Living in a conservation area can also increase the price.

Materials will be covered later, but it helps to have a general rule of thumb when considering the price. For example, vertical sliding sash windows can have highly varying prices depending on their size.

Our quotes prices are only a baseline and can also be impacted by other details or changes to the design. However, we can offer carefully-constructed quotes that give you a more reliable cost estimate for your new project, so contact us if you want to know more about how much the project could cost.

Oxfordshire Heritage Sash Window Suppliers

Our bespoke sash windows are all designed to fit with the client’s personal needs, whether that’s in terms of style, size, or materials. Windows and doors are an important part of retaining a home’s style, and we can offer complete replacement of classic sashes while still retaining the original function and design.

Types of Sash Windows We Offer

While all of our modern vertical slider windows consist of the same high-quality designs and materials, we can create quite a wide variety of different designs and types. In addition, our expert staff can help you get the exact kind of replacement windows you want, whether you want a modern design or something traditional.

Box Sash Windows

Spring sash designs trade the weight-based pulley system for a spring-loaded mechanism, making opening and closing the windows slightly easier. In addition, unlike conventional box sashes, they don’t need to conceal a weight system to use slimmer and smaller frames.

This makes the difference between them primarily based on personal preference. However, both work exceptionally well, and we can provide the same excellent quality no matter which option you choose.

Georgian Sash Windows

A Georgian sash uses a “six over six” design, with both panes having six individual spaces separated by small strips of wood. These are prevalent designs and are some of the oldest methods available. This makes them a popular choice for traditionally-styled homes.

Victorian Sash Windows

Victorian sash designs are a “two over two” layout, with two individual sections on each pane. These are another prevalent choice and offer the same benefits as Georgian designs.

Edwardian Sash Windows

Edwardian sashes are made with a “six over two” design, meaning that the top pane has two rows of three sections. These often offer a lot of visibility since the lower pane is a single piece with nothing obstructing it.

Sash Window Frame Materials

Vertical slider windows consist of many different materials, and multiple material choices can change the overall style and quality of what you end up receiving. We have worked with all kinds of sashes and can provide the right kind of result to our clients, even if that means creating custom-built windows with specific material selections.

Timber Sash Windows

Timber windows are another design meant to replace wooden windows, mostly by using real wood (specifically, toughened timber) and adding additional finishes to help protect it. These can be better than even uPVC frames and offer much more character, but they also tend to be more expensive.

Sash Window Glass Types

The glass used in a sash might not impact its functionality at lifting upwards, but it can still impact the result that you get. There are two primary choices: clear and frosted. Both have all the benefits of our design initiative and hit excellent levels of quality.

Clear Glass

Clear sashes are easy to see through, offering an unobstructed view from both sides. These lower your privacy unless you have blinds or a curtain but can save money overall since they are cheaper than the alternative.

Frosted Glass

Frosted sashes scramble the light passing through them, giving you more privacy in exchange for a clear view. These keep all the benefits of standard windows and can still accept double-glazing and thermal insulation features.

Frequently Asked Questions

Can Vertical Sliding Sash Windows Be Double Glazed?

Vertical slider windows can easily be double-glazed, including timber vertical slider windows. Triple-glazing is sometimes an option for more thermal efficiency and thermal insulation.

Do Traditional Sash Windows Need A Lot Of Maintenance?

Most of our windows, including double-hung sash windows and other specific designs, need very little maintenance. With only one moveable pane, there isn’t much that can wear down.

What Material Is Best For A Replacement Sash Window?

There isn’t a single best material for these projects, and most work well in any situation. Like doors and other home additions, the rapid increase in customers using a particular material is usually due to personal preference.

Should I Repair Or Replace My Sash Window?

We design our sashes for maximum durability, aiming for excellent levels of quality whenever we can. In addition, we can offer repair and replacement services as needed.

How Do You Clean These Windows?

Cleaning sashes is handled just like a standard design. There are no significant ‘tricks’ involved.

How Much Does It Cost To Repair A Sash Window?

Repairing a sash in older properties may not be as expensive as replacing it, but upgrading is often better. The same can be said for doors and other major design features.

What Is The Difference Between Sash And Casement Windows?

Casement designs are single-pane and swing outwards. Sash designs slide upwards into the second pane up above.

Sash Windows Benefits

Higher thermal insulation and thermal efficiency mean reduced energy bills, helping you save money in the long term. Since glazing is the best way to boost thermal efficiency by adding a new layer of thermal insulation, our entire range of panes can accept it.

We can work with customers and businesses alike to provide the perfect options for your home, whether they are new builds or existing structures. We aim for excellent levels of quality in an environmentally friendly way, offer outstanding design initiatives, and use quality Safeware security hardware in our projects.
