The big difference between sash windows and casement windows, is that sash windows do not use a hinge to open, they slide instead. Each sash window has got two panels, where one or both of them are able to slide up vertically behind the other. To keep the window in position there are counterbalances and cords which permit the window to be opened by any amount for different ventilation needs. Classic, old fashioned sash windows do not move in any other direction than simply up and down, but more modern versions support horizontal or vertical movement, in addition to tilting designs that are easier to clean.

One of the major pluses that sash windows have over casement windows is that they're far more efficient for the ventilation of your rooms. When both window sashes can be moved you are able to leave a gap both bottom and top, which generates a convection flow of air within the room with warmer air escaping through the top gap, and cool air entering through the gap at the bottom. This gain is especially helpful in sunny summer months and helps to improve personal comfort levels around your property in Harrow.

Extra security measures for traditional sash windows give peace of mind for a property owner in Harrow, through the use of double or reinforced glazing, locks, stops and threaded bolt screws to stop any unauthorised opening of your windows. The addition of a frame to frame sash lock is a very good type of security for sash windows in Harrow. This makes use of a bar or bolt which anchors the bottom frame to the upper sash and stops either window from being opened. Because it can't be accessed from the outside by would-be burglars, security is enhanced.

A specialist Harrow sash window contractor will offer a free assessment of your frames and windows before giving advice on possible measures to resolve your problems. Whether your sash windows need attention due to loose corner joints, rotten frames, cracked glass or snapped cords, there's a fair chance they can be successfully repaired or refurbished. Nonetheless, you must weigh up the advantages and disadvantages when it comes to what's actually achievable and what is worth doing from a cost viewpoint.

Sash Window Quotes in Harrow Greater London


Looking through the multifarious kinds of sash windows that you can buy online and in sales brochures can be somewhat bewildering. It's simpler to think of there being just three principal designs: Edwardian, Georgian and Victorian. Each offers their own variations that can be adapted for your property style.

Sash Window Installation Near Harrow Greater London

Georgian - Traditionally features 6 separate panes in the top sash, over 6 separate panes in the bottom sash, "6 over 6". The Georgian style can be customised to Half-Georgian (6 panes in one half, a single pane in the other), or another Georgian-variant which can have different sized panes in top and bottom, provided that one of the sashes consists of six panes.

Victorian - The Victorian sash window is commonly a two over two panel design which also includes a central bar, or adaptations such as asymmetric (three over two, two over three etc).

Edwardian - With a six over two configuration, the Edwardian is quite similar to the Half-Georgian style of sash window.

It's way simpler to ask your your local window installation company for their recommendations on the best style to match your property in Harrow.

Each of these types can be built in all window sizes, including coupled and bay windows. There is in fact another major type of sash window, which is called the Yorkshire Sash Window. Integrating with any of the three main designs and their variations, this style is a horizontally sliding window.

Along with the many different styles of sash windows, these products are also made from a number of different materials to accommodate your individual taste. The classic sash windows from the 17th century, and for most of the past four hundred years were made out of timber. Many of today's wooden sash windows are manufactured from sustainable softwoods like Scots pine, European redwood, Douglas fir and deal, but the original ones were mainly made out of English oak, of which was at that time more abundant.

Aluminium sash windows became available in the 70's, and in no time at all the first uPVC versions began to appear, which because of their durability, high level of security, energy efficiency and low-maintenance attributes, became more and more popular in Harrow.

Sash Window Trickle Vents Harrow

Ensuring that all your rooms have some kind of ventilation is vital if you are installing sash windows in your property in Harrow. This is something that is often ignored as we all strive to enhance the insulation in our homes. But, if you're to prevent problems such as penetrating damp, condensation and mould, a degree of ventilation is essential.

Without actually opening your windows constantly, the fitting of trickle vents is the simplest way to aid ventilation. If you've picked uPVC windows they will often already have trickle vents, however professional installation may be needed for some other kinds of sash window.

Fitted at the head of a window, a trickle vent allows air to pass through from outside and "trickle" vertically down the window panes, which helps to stop condensation building-up on the glass surface, and reduce the issues that are linked to this phenomenon.

So you don't detract from the clean, smooth lines of your windows, try to buy low-profile and flush fitting trickle vents where possible. Some trickle vents are fairly conspicuous and will not look as elegant as the flush fitting ones.

uPVC Sash Windows Harrow

Sash windows have been used in Harrow for four hundred years or more. In fact, there are still surviving examples dating from about 1670, in various regions of Britain. Customarily constructed from timber, over the last few years, sash windows have become available in all sorts of different materials. In all aspects of construction oak was the timber of choice, but as well as oak, ash was also often used for building sash windows. When looked after correctly these timbers are strong, durable and guaranteed to survive for many years.

However, in the world today hardwoods are expensive and their widespread use is a major factor behind deforestation throughout the world. Although timber is now supposed to be responsibly sourced, it has been estimated that over 60% of the United Kingdom's imported tropical timber still comes from illegal logging.

Because of such issues, modern wooden sash windows are predominantly manufactured from rapid growing softwoods, such as douglas fir, Scots pine and European redwood. Softwood is generally far more likely to come from renewable sources, and is also significantly cheaper than hardwood. The downside with softwood is that it is not as long lasting as hardwood, and needs more frequent treatments and maintenance.

The construction of sash windows has been revolutionised over the past forty years or so, as alternative materials have been introduced. The development of uPVC sash windows started during the mid-80s. From the beginning, these were developed to emulate conventional timber sashes as accurately 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 window benefits include:

  • A-rated energy efficiency.
  • Custom made for your needs.
  • Highly weather resistant.
  • Available in wood grain effect.
  • No painting or sanding.
  • Easy clean characteristics.
  • Improved home security.
  • Low or no maintenance.
