Modern window springs for sash windows are concealed to avoid this issue.1. AestheticsIn contrast to PVC-u windows, which are constructed to modular imperial sizes Timber sash windows can be restored to their original dimensions. This permits the re-installation of timber sash windows in order to meet the current energy requirements and comply with conservation area regulations. It also offers an option that is superior to the uPVC alternatives.Sliding sash windows were initially only found in large buildings or public buildings, but this changed when production was less expensive and craftsmen were able to produce larger frames with more glass. At the end of the 18th century, sash windows were the most popular wooden style in British homes. As they were easy to open, sash windows let light into rooms without curtains.The early windows were made of clear glass however, by the 17th Century sash windows started to become more attractive. They were initially made of colored glazing bars, also known as mullions. These windows were quite expensive at the time, but as glass production became more efficient and cost-effective, they became a feature of many period houses.In the 19th century, it became possible to create large, strong glasses that didn’t need supporting bars. This allowed the frame’s size to be increased even more, which in turn meant more of a view out of the window. This was a significant innovation.Another significant improvement was the introduction of the double-hung sliding windows at the end of the I920s and beginning of I930s. This allowed both the upper and lower sash to be opened at the same time and allowed for better ventilation to a building.The most common kind of sash is made from slow grown deal (pine) however oak was utilized in more luxurious buildings and in earlier examples. A parting bead separates the two sashes and it is important that this is maintained to prevent rattles and draughts. It is also important that sash pulleys and idler wheels are in good shape as they assist in operating the window.2. Energy efficiencyAs larger and clearer sheets of glass became available, sash windows began to replace hinged casements. Glass plates were set in frames of timber that were rebated, then pinned with glazing sprigs and putty was applied to the frame’s two sides to ensure watertightness. This form of glazing gradually replaced leaded lights.Sashes were introduced, which led to increased demand for ironmongery. The most basic fittings were brass pulleys (and later cast-iron) weights and stoppers for sashes shutter hinges and handles as well as various fasteners used to secure the sashes. These were often decorated in patterns, inscriptions and engraved patterns to identify the maker.Sash windows can be very energy-efficient with regular maintenance. But, if you don’t maintain them, they can become draughty and let in cold air. Paint and putty can cause draughts. You can fix this problem with wood-to-timber products.The industry of replacement windows is based on the perception that traditional windows are rotten and beyond economical repair, while they can be maintained with just a little care. However, repairs to these windows are costly and can cause substantial disruption to the home. To prevent this homeowners often choose to replace their windows with PVC-u windows made by one of the many “one stop shop” installation companies. They can replace all windows in a home in one day, thereby saving time and avoiding the need for multiple tradesmen to coordinate. These windows can be fitted with ‘energy-saving double glazing to get higher energy ratings than traditional windows with sash. However, these double-glazed units cannot duplicate the proportions and section of the sashes made of timber from the past.3. SecurityTraditional windows can be made secure without compromising their style. Ironmongery like sash chain, mortice bolts, and sash lock can be put in place. They can be fitted in a way that the window is open for ventilation or cleaning. These are typically minimal in appearance, as they are designed to complement the sash window. window repair cambridge can be used in conjunction with traditional sash window catches. They should be replaced by more robust models, such as ones that have double screws, or sprung levers in order to reduce the chance of being hammered.Sash-window frames were traditionally made from slow-growing deal or, in more prestigious houses, from oak. If the glazing bars are in good condition and are not damaged, they should be left. Where possible, the timber cills should be replaced with wood that matches. Many PVC-U companies offer a one-stop installation service. They can take down and replace windows on an entire house in just one day, without involving other tradespeople.4. VentilationWhen sash windows first introduced in the 17th century they allowed a large amount of light to flood into buildings. By the end of the 18th century they were adapted to allow more light into rooms and larger glass panes began to be made. The result was a more streamlined appearance, and windows with a greater quality of design than before.Sash windows were introduced that required a brand new range ironmongery. Early pulleys were constructed of wood. Later Victorian ones were made of brass or a mix of leaded and wood. There were also various kinds of shutter hinges and knobs. The ironmongery components should be kept and cleaned to ensure that the exquisite quality of their design can be appreciated.To keep them in good condition, timber windows must be maintained. Inattention to maintenance can result in:sashes that no longer slide easily.holes in the frame allow water that can cause decay and damage.break down of the putty and allow water penetration that could cause decay in the frame and cill.Steel casement windows gained popularity in the I920s and I930s because they were strong and slim, and also because they were cheap and matched the trend of healthy living. However, research has proven that traditional softwood sash windows are as efficient thermally as double-glazed windows made of PVC-u, and are more attractive than the modern sleek design of casement windows.The industry of replacement windows has made a significant effort to persuade house owners that their windows are dirty, noisy and beyond repair. Many older timber windows can be repaired and utilized for a longer period with minor repairs.5. MaintenanceThe traditional sash windows require regular maintenance and inspection.

The removal of sashes could also result in structural movement within the frame, causing the sash to not close properly. The sash may also become stuck in the open position, allowing water and draughts into the building.Moisture penetration is a frequent cause of damage to windows made of timber. This can be avoided with regular maintenance as well as thorough painting, and then removing the cause of dampness. The paint can be removed to reveal the soft, decaying wood. Any rotten sections of timber should be cut out and the affected part carefully wrapped or pieced back using replacements made from the same type of wood as those remaining. This method of repair increases the amount of original fabric left, and is among the least invasive methods of treating decay of timber to timber.The use of a resin-based wood consolidant is another alternative to the traditional method of sanding and staining. This is brushed onto the surface of the wood to stabilize it and shield it from further damage. It is particularly beneficial for the treatment of sash cords and pulleys where it can help to prevent breakage.It is essential to preserve and not replace any historic ironmongery, like the sash latches and stays.
