Unlike casement windows, sash windows do not use a hinge mechanism for opening. Two window panels are installed with one, or both, able to slide up vertically behind the other. To keep the window in place there are sash cords and counterbalances which enable the window to be opened by any amount for varying ventilation requirements. The classic sash windows did not move in any other direction than up and down, but modern day versions support vertical or horizontal (referred to as Yorkshire Sash) movement, and also tilting designs which are easier to clean.

Enhanced room ventilation capabilities is one of the important advantages that sash windows have over their casement counterparts. If both bottom and top window sashes can be moved you can create a convection air flow within your home, with cool air entering through the lower gap, and warm air escaping through the upper gap. During the hot summer months in Derry, this is particularly valuable, helping to increase your levels of personal comfort.

Enhanced security for traditional sash windows gives peace of mind for any householder in Derry, by the installation of double or reinforced glazing, threaded bolt screws, locks and stops to stop any potential intruder from opening your windows. Adding a frame to frame lock is one of the most effective types of security for sash windows in Derry. Preventing either window from being opened, this kind of lock involves the use of a bolt or bar which anchors the top sash to the lower frame. As it can't be accessed from the outside by would-be intruders, security is improved.


If your house in Derry has sash windows fitted and they no longer work as they should (not opening, sticking etc), it's the perfect time to think about either restoring or replacing them. A professional Derry sash window installer will be able to give you advice on whether it is possible to repair and restore your existing windows, or would perhaps be better to swap them for brand new sash windows.

If a complete refurbishment is the decided course of action for your existing sash windows in Derry, then for this work to be successfully accomplished, they will have to be taken out of their frames. Some sash window repairs might not be that complicated and may simply involve scraping off a few layers of paint which have built up over time, or perhaps the frame might need to be put in a special jig and tightened if the panes of glass are rattling and draughty. A professional Derry sash window company should offer an inspection service of your frames and windows before giving advice on possible measures to rectify your problems. Whether your sash windows need attention due to frayed cords, broken glass, defective mechanisms or rotten frames, there is a fair chance they can be successfully refurbished. Having said that, you should weigh up the advantages and disadvantages in terms of what's doable and what is genuinely worth undertaking from a cost perspective.

If you need to fix an existing sash window, or are trying to make a replacement one, there is a selection of sash window mouldings and components. When minor repairs are required, this is particularly helpful, since you can just buy the exact parts that you need for the task. Mouldings that can typically be found include: staff beads, stiles, step cills, transom drips, top & bottom meeting rails, bottom rails, sash stiles, sash bars, ovolo glass beads, parting beads and glazing bars.

Sash Window Quotes in Derry Northern Ireland


Looking at all of the various different styles of sash windows that are offered in sales catalogues and online can be a bit baffling. It's easier to think of there being just three major designs: Georgian, Edwardian and Victorian. Each one of these 3 patterns has their own individual variations which can be modified for the style of your particular home in Derry.

Sash Window Installation Near Derry Northern Ireland

Georgian - Typically comprises 6 independent panes in the top sash, over 6 independent panes in the bottom sash, (six over six). There is a Georgian-variant which sees a sash window which can have different sized panes in the top and bottom, as long as one of the sashes counts 6 panes, while a Half-Georgian is a modification of the Georgian with a single pane in one half, and six panes in the other.

Victorian - A two over two panel design which may also incorporate a centre bar, or different variations such as asymmetric (two over three, three over two etc).

Edwardian - Featuring a 6 over 2 configuration, the Edwardian has a fairly similar look to the Half-Georgian style of sash window.

It is much easier to ask your your local window installation company for their recommendations on the best design to suit your home in Derry.

All of these sash window patterns can be adapted to different types of window, i.e. couple or bay windows, as well as for any size of window. There is a 4th main kind of sash window which is known as the Yorkshire Sash. Incorporating any of the three main elements and their variants, this type is a horizontally sliding window.

Sash windows during the past, only had one single pane of glass. If your property is situated in a conservation area, or is listed, you might need to replace your sash windows with a similar arrangement as your current ones.

This enables you to replace your sash windows with no difference in the look of the overall building.

An established sash window contractor in Derry can offer advice about ways to conform to the local restrictions for your area, whilst supplying the best and most cost-effective materials on the market. When existing materials must be restored, due to demands by your local authority or conservation official, a window by window inspection may be necessary to reduce any impact to the building. A trustworthy company will be ready to perform this survey and compile a detailed report for the planning officer, including technical drawings, information about your renovation scheme and necessary replacement works.

It may be feasible to do an enhancement of your sash windows in Derry by installing secondary glazing. This enables you to prevent condensation, improve your thermal efficiency and reduce noise by the installation of a vertical sliding secondary glazing pane inside your sash window. The use of secondary glazing helps to maintain the traditional character and appearance of the building and can generally be implemented even if you are restricted by planning constraints in the case of a listed building.

uPVC Sash Windows Derry

Sash windows have been popular in Derry properties for at least four hundred years. The earliest surviving examples in the British Isles, date from 1670. Customarily constructed from timber, in recent times, sash windows have become available in different materials. Over the centuries oak and ash were the favoured timbers for making sash windows, as they were used in every area of construction. Lasting for many years when looked after properly, these timbers are well known for being strong and durable.

Because their overuse is one of the main causes of deforestation across the world, hardwoods are now expensive. Timber nowadays is meant to originate from totally sustainable sources, however based upon estimates it's thought that approximately 60 percent of tropical hardwood arriving in the UK comes from countries where illegal logging is widespread.

For this and a number of other reasons, rapid growing softwoods such as redwood, deal and Baltic pine are now being used for making modern timber sash windows. Softwoods mostly come from sustainable sources, and are significantly cheaper than hardwoods. The drawback with softwood is that it does not last as long as hardwood, and needs to be more regularly treated and maintained.

The construction of sash windows has been revolutionised over the last forty years, as other materials have been used. The first uPVC sash windows were developed in the mid-1980's. From the beginning, these were developed to emulate conventional timber sash windows as closely as possible. Most of the first uPVC sash windows were white, but over the years a range of alternative colours were added.

These benefits can be gained by fitting uPVC sash windows:

  • High thermal efficiency.
  • Available in wood grain effect.
  • Custom made for your needs.
  • Simple to clean.
  • More secure.
  • No need for sanding or painting.
  • Low maintenance.
  • High weather resistance.

Sash Window Trickle Vents Derry

If you have installed sash windows in your property in Derry, you need to ensure that each room has enough ventilation. This is an aspect which is often ignored as we all try to improve the insulation of our homes. But, if you're to minimise issues such as condensation, damp penetration and mould growth, a certain level of ventilation is essential.

Without constantly opening your windows, the fitting of trickle vents is the easiest way to enable ventilation. Many uPVC sash windows come with trickle vents already fitted, but with some other sash windows you might have to get them professionally installed.

Trickle vents are fitted at the top of a sash window, and air enters from outside and "trickles" vertically down the window, thus preventing condensation on the interior glass surfaces, and the related issues that this triggers.

So that you do not ruin the smooth, clean lines of your windows, try to buy flush fitting low-profile sash window trickle vents where possible. These are far less obtrusive than some trickle vents on the market and will appear much tidier once in place.

Sash window mouldings are available in softwood or hardwood, and a brief search online for "sash window mouldings" or similar will uncover a few potential merchants, with oak, pine, meranti and sapele versions being offered. You'll not generally be able to buy these mouldings at your local DIY superstore or B&Q, given that they are rather specialist components.

Yorkshire Sliding Sash Windows Derry

The "Yorkshire Sliding Sash" or "Yorkshire Slider" is the fourth and last kind of sash window, after the more widely acknowledged Georgian, Victorian and Edwardian patterns. Some folks refer to this style as the "Horizontal Sliding Sash Window", as it perfectly describes the mechanics of this window, with the sashes sliding horizontally (from side-to-side), in contrast to the other designs which all slide up and down (vertically). Thought to have originated from the North Yorkshire region, these windows are frequently seen in period cottages and other attractive listed buildings.

Sash Window Repair Derry

Traditional style timber sash windows can get pretty scruffy if they are neglected and not thoroughly maintained over time.

At a quick glance most property owners wouldn't get the gist of the problems that are present and getting worse beneath all those coats of gloss paint, but trust me, there are thousands of sash windows out there that are in desperate need of repair. Now, this is not the type of project that can be done by any ordinary odd job man or wood bodger, it calls for the craftsmanship of a sash window expert who knows precisely what they are up to.

Unless they've been genuinely neglected for a fair number of years, then the majority of timber sash windows can be repaired with some hard work and effort, so do not be duped by an intake of breath and a brazen attempt to sell you replacements - try somebody else if that is all they've got to offer.

If you call in a genuine craftsman, they'll do a comprehensive assessment of your windows, put together a detailed report about what can be successfully mended and what needs to be replaced. So that you are in a position to make a conscious decision about how you'd like to proceed, they'll also give you a fully itemised estimate. The commonest sash window repairs include:

Sash Window Locks Derry

Although the modern aluminium and uPVC sash windows offer a very good level of security, some of the older wooden sash windows are well known for their susceptibilities. If you're hunting for sash window locks or considering other security enhancements for your timber sash windows in Derry, there are a range of options available.

Making sure your timber sash windows are working perfectly and well-maintained is the first step in keeping them secure. Beyond that, there are a number of measures that you can take.

You can put in window fasteners, which enable ample ventilation while preventing access by criminals. You can install restrictors which limit how much the sashes can be opened. You can introduce reinforced glass which is tougher and more difficult to smash. You could fit dual screws which bolt through both top and bottom sashes to prevent the window being opened.
