How to Restore Timber Sash Windows in Cambridge Many homes in Cambridge have sash windows with traditional designs and homeowners are proud of how they look. However, sash windows may get stuck and be difficult to open or close. This is usually due to moisture which can cause the wood to expand. Box sash windows were traditionally operated using chains, cotton cords and weights made of lead. Modern window springs for sash windows are concealed to avoid this issue. 1. Aesthetics Unlike PVC-u windows that are constructed according to imperial sizes that are modular the timber sash windows are able to be restored to their original size. This permits the re-installation of timber sash windows to comply with current energy standards and conform to conservation area regulations. It also gives a window with a far superior appearance than uPVC alternatives. Sliding windows with sash were initially only used in large buildings or public buildings. However this changed as production became cheaper and artisans could produce larger frames with more glass. In the 18th century, Sash windows were the most popular wooden style in a majority of British homes. Sash windows were easy to operate and allowed light to enter rooms without the need for curtains. The early windows were made of glass that was plain However, by the 17th Century the sash windows began to become more attractive. They were initially made of colored glazing bars or mullions. They were expensive at the beginning but as glass production became cheaper and more efficient, they were commonplace in many homes of the period. By the 19th century it was possible to create large, sturdy glass that didn't require supporting bars. This allowed the frame's size to be enlarged further, which allowed for a wider view out of the window. This was a significant innovation. The introduction of the double-hung sliding sash was a important improvement that occurred in the I920s and the beginning of the I930s. The double-hung sliding sash was another significant improvement that came about at the end of the I920s and at the beginning of the I930s. Oak was used in older examples and for more prestigious buildings. It is important to maintain the parting bead that divides the sashes. This will help prevent draughts and rattles. It is also crucial that the idler and sash pulley wheels are in good shape as they aid in operating the window. 2. Energy efficiency Sash windows replaced hinged cases as larger and clearer sheets were made available. Plate glass was set into frames made of timber, which were secured with glazing sprigs and putty was then sprayed onto the frame's sides to ensure watertightness. This type of glass gradually replaced the leaded light bulbs. The introduction of sashes resulted in an need for a larger variety of ironmongery with the most basic fittings being brass pulleys and lead (and later cast iron) weights, sash stops shutter hinges and knobs and a variety of fasteners that secured the sashes in place. These were usually decorated with patterns, inscriptions and engravings to identify the maker. Sash windows can be extremely energy efficient when they are maintained regularly. However, if they are not maintained, they may become drafty and let in cold air. Putty and paint can cause draughts. This can be remedied by making use of wood-to-timber repair tools that are proprietary. The market for replacement windows rests on the assumption that old windows are damaged and beyond repair, but they can be easily maintained with just a little care. However, repairs to these windows can be costly and cause considerable disruption to the home. Many homeowners opt to replace their windows using PVC-u from a large “one-stop shop” company for installation. They can take down and replace all windows in a home in a single day, avoiding the need to co-ordinate different tradesmen and making the entire process much faster. These windows can be fitted with energy-saving double glazing to get higher energy ratings than the traditional windows with sash. However, these double-glazed units cannot duplicate the proportions and section of traditional timber sashes. 3. Security It is possible to secure traditional windows without compromising their style. Ironmongery such as sash chain, mortice bolts and sash lock could be used. They can be fitted in a manner that the window can be opened for ventilation and cleaning. These products are usually not noticeable, since they are designed to match the sash window. They can be used with traditional sash window catch. They are best replaced with more robust versions like those with double screws, or sprung levers to decrease the risk of being hammered. Sash-window frames are usually made of oak or slow-grown deal. If the glazing bars are intact, they should be retained. If it is it is possible, the cills of the timber should be replaced with wood that is in line with. upvc windows cambridge -U companies usually offer a one stop shop installation service, which includes removing and replacing windows across a house in a day without the need to engage other tradespeople or co-ordinate various visits from a number of different suppliers. 4. Ventilation Sash windows were introduced in the 17th century and allowed for a significant amount of light to be absorbed into buildings. By the end 18th century, they were adapted so that even more light could be let into the rooms. Larger glazing panes were also made. The result was a lighter look and windows with more elegance. The introduction of sash windows also demanded a new range of ironmongery. Early pulleys were of wood, later Victorian ones were made of brass or a mixture of lead and wood, and there were many kinds of shutter hinges and knobs. The ironmongery pieces need to be maintained and cleaned to appreciate their beautiful design. To ensure they remain in good condition, wooden windows require regular maintenance. Lack of attention to them regularly could lead to: Sashes that no longer slide easily. Holes in the frame which allow water to enter and cause damage and decay. break down of putty allowing water penetration that can lead to decay in the frame and cill. Steel casement windows became popular in the I920s & 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 just as thermally efficient as double-glazed windows made of PVC-u, and can be more attractive than the sleek lines of contemporary casement windows. The industry of replacement windows has made a significant effort to convince homeowners that their windows are old, dirty, and beyond economic repair. The truth is that a lot of old timber windows are in good condition and with minor repairs can easily be repaired for many years to be. 5. Maintenance A traditional sash window requires regular maintenance and inspection. Failure to do this can lead to broken sash cords, excessive wear on the glazing bars and deterioration of paint and putty. The removal of sashes can also result in structural movement within the frame, which can cause the sash not to close properly. The sash could also get stuck in its open position, allowing water and draughts to enter the property. Moisture penetration is the most common cause of damage to timber windows. This can be avoided by regular maintenance by thorough painting and eliminating the cause of dampness. The paint can be removed to reveal the soft, decaying wood. Any rotten sections of timber must be removed and the affected part carefully cut or pieced with replacements made from the same type of timber as those remaining. This method of repair maximises the amount of original fabric left, and is among the least invasive methods for treating timber-to-timber decay. A resin-based wood condenser is a viable alternative to traditional sanding or staining. This is brushed on the surface of the wood to protect it and stabilise it. It is particularly beneficial in the treatment of pulleys and sash cords which can help prevent the breakage. It is essential to preserve and not replace any old ironmongery, like stay latches and sash latches. They can be extremely difficult to replace without damaging the quality of the original design. It is also recommended that the use of modern aluminum fittings such as sash lifts and chain stays should be avoided if possible as they can cause corrosion and deterioration to frames and sashes made of timber.
