Unlike casement windows, sash windows don't use a hinge mechanism for opening. Two window panels are involved with one, or both, able to slide vertically up behind the other. To keep the window in place there are cords and counterweights which enable the window to be opened by any amount for differing ventilation needs. Classic, old fashioned sash windows can't be moved in any other direction than vertically, but more modern versions allow for vertical or horizontal (known as Yorkshire Sash) movement, and also offering the possibility of tilting for easy cleaning.

A leading benefit of a sash window over a casement style is its enhanced system of ventilating a room. If both upper and lower sash window can be moved you can produce a convection flow of air within your property, with cool air entering through the gap at the bottom, and warm air exiting through the upper gap. This gain is particularly helpful in summer months and helps to improve personal comfort levels around your house in Belfast.

To stop any potential intruder from opening your windows and increase security for traditional sash windows, stops, threaded bolt screws, locks and reinforced or double glazing can be used to give reassurance for householders in Belfast. Fitting a frame to frame lock is one of the best types of security for a sash window in Belfast. Preventing either window from being opened, this kind of lock involves the use of a bolt or bar which secures the upper sash to the bottom frame. Because potential intruders have no way of accessing it from the outside, security is further enhanced.

If a complete refurbishment is the decided route for your existing sash windows in Belfast, then for the work to be successfully accomplished, they'll need to be removed from their frames. It might be as easy as removing several layers of paint which have accumulated over the years, or maybe if the window glass is draughty and vibrating, the frame might need tightening in a purpose built jig. You'll probably find that your local sash window contractor in Belfast will offer a free assessment of your frames and windows to establish any issues, propose solutions, and provide an estimate for the work involved. Generally speaking sash windows can be repaired, whether they're affected by loose corner joints, snapped sash cords, shattered glass or rotten frames. You should keep in mind though, that for all practical purposes there is frequently a balancing act between what's doable and what is actually more cost-effective in the long run.

Sash Window Quotes in Belfast Northern Ireland


It can be confusing if you look at a sales catalogue or online at all of the various different styles of sash windows which are available. If you just consider the three main designs, that is to say: Edwardian, Georgian and Victorian, it should be more straightforward. Each has their own variants that can be customised for your style of home.

Sash Window Installation Near Belfast Northern Ireland

Georgian - The typical design of the Georgian sash window is "six over six", meaning that it comprises 6 independent panes in the top sash, over 6 independent panes in the bottom sash. The Half-Georgian is an adaption of this style with 6 panes in one half, and a single pane in the other, while another Georgian-variant sees a window which can have different sizes of pane in the upper and lower, as long as one half of the window has 6 panes.

Victorian - The Victorian sash window is commonly a 2 over 2 design which also includes a centre bar, or adaptations like asymmetric (two over three, three over two etc).

Edwardian - A six over two style that is fairly similar in design to a half Georgian.

To find which is the correct design for your property in Belfast, you can contact your local sash window installer, instead of beating up your brain going over all these different versions.

Each of these styles can be made in any window sizes, including bay and coupled windows. There is actually another major kind of sash window, which is called the Yorkshire Sash Window. This pattern of sash window slides in a horizontal direction, and can incorporate any of the main elements and variants of the other three.

Along with the various designs of sash windows, these products are also made out of a number of different materials to accommodate your individual tastes or preferences. The first sash windows from the 17th century, and for almost all of the last 400 years were made out of wood. Most of the modern wooden sash windows are manufactured from sustainably sourced softwoods like Douglas fir, redwoods, deal and Scots pine, but the earlier windows were mainly made of English oak, of which there were plentiful supplies.

The first aluminium windows made an appearance during the 1970s, followed closely by uPVC sash windows, which became progressively more popular in Belfast thanks mostly to their high level of security, low-maintenance qualities, durability and energy efficiency.

An enhancement of your sash windows in Belfast could be feasible by using a secondary glazing solution. By adding a vertically sliding secondary glazing panel inside your sash windows you can improve thermal efficiency, prevent condensation and reduce noise transmission. Secondary glazing is a great way to improve your sash windows, while still preserving the original character and integrity of the building. And even if you are limited by planning constraints, as in the case of a listed building, this can still usually be implemented.

uPVC Sash Windows Belfast

Sash windows have been widely used Belfast buildings for 400 years or more. Around Great Britain there are still sash windows which survive from the late 17th century. Traditionally made of timber, over the last few years, sash windows have become available in different materials. Oak was the traditional timber used in every area of construction, and sash windows are no exception, although ash was also widely used. Strong and durable when properly maintained, these timbers were acknowledged for their long lasting qualities.

Because their widespread use has caused deforestation across the world, hardwoods are now very expensive. Although timber is now supposed to be sourced responsibly, it has been estimated that over sixty percent of Great Britain's imported tropical timber still comes from illegal logging.

Quick growing softwoods such as redwood, deal and Baltic pine are now more frequently used in the construction of sash windows, due to these concerns. Cheaper than hardwoods, softwoods are also more inclined to come from sustainable sources. The downside is that if they aren't given regular treatments and maintenance, softwoods aren't as durable and long lasting as hardwoods.

The manufacture of sash windows has been transformed over the past 40 years, as alternative materials have been used. The first examples of uPVC sash windows were developed during the mid 1980s. From this beginning, these were made to emulate traditional timber sashes as closely as possible. In the beginning, most of the uPVC sash windows were white, but as manufacturing techniques were refined, more and more colours were offered.

uPVC sash windows have these benefits:

  • Can be made to order.
  • No painting or sanding.
  • Easily cleaned.
  • High thermal efficiency.
  • Available in traditional wood grain effect.
  • High weather resistance.
  • Virtually maintenance-free.
  • Improved home security.

With aluminium being sustainable, recyclable and eco-friendly, this material offer many benefits, and sash windows made out of aluminium are practically maintenance free. The contemporary aluminium sash windows on the market today are double-glazed, properly insulated and meet all of the latest building requirements. They're far superior to the aluminium windows of the 70's.

Sash Window Locks Belfast

Today's sash windows are reasonably secure, and while it is possible to add extra measures it's not usually needed with aluminium and uPVC units.

You can put in window fasteners, which enable a certain degree of ventilation while at the same time stopping access by intruders. You can put in sash window restrictors which control how much the windows can be opened.
