How to Restore Timber Sash Windows in Cambridge Many homes in Cambridge have sash windows with traditional designs and homeowners are proud of the way they look. Sash windows can become stuck and are difficult to open and close. This is typically due to moisture that can cause the wood to swell. Traditionally, window boxes utilised chains, cotton cords or lead weights to operate. Modern window springs for sash windows are concealed to solve this problem. 1. Aesthetics Timber sash windows, in contrast to PVC-u windows that are made in imperial sizes, which are modular, can be restored to original dimensions. This permits the re-installation of timber sash windows to meet the current energy requirements and comply with conservation regulations for areas. It also provides windows that are superior to the uPVC alternatives. Sliding sash windows were originally only found in large buildings or public buildings, though this changed when production became cheaper and craftsmen could create larger frames using more glass. By the end of the 18th century, sash windows had become the most sought-after wooden style in British homes. Sash windows were simple to operate and let light into rooms without the use of curtains. Repair My Windows And Doors were made of clear glass However, by the 17th Century the sash windows began to become more ornamental. They were initially made of colored glazing bars or mullions. These windows were quite expensive at the time but as glass production became more efficient and less expensive, they became a part of numerous period houses. In the 19th century, it was possible to make large, sturdy glass that did not need support bars. This allowed the frame size to be enlarged further, which allowed for a wider view out of the window. This was a significant improvement. Another significant improvement was the introduction of the double-hung sliding window at the end of I920s and at the beginning of 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. The most common kind of sash is made from slow-growing deal (pine) but oak was utilized in more luxurious buildings and in earlier examples. It is essential to keep the separation bead that divides the sashes. This will prevent draughts and rattles. The sash pulleys, idler wheels and sash rollers are also crucial to the functioning of the window. 2. Energy efficiency Sash windows were replaced by hinged casements as larger and clearer sheets were made available. Glass plates were set in frames of timber that were rebated, then secured with glazing sprigs and putty was then sprayed onto the frame's sides to ensure watertightness. This type of glazing gradually superseded led lights. Sashes were introduced, which led to a greater demand for ironmongery. The most basic fittings were brass pulleys (and later cast-iron) weights, sash stoppers shutter hinges, handles and shutter hinges, and a variety of fasteners to secure the sashes. They were often decorated with patterns, inscriptions and engravings to identify the maker. Sash windows are energy efficient if they are maintained regularly. However, if they are not maintained, they can become draughty and let in cold air. Draughts can also result from the degeneration of paint and putty. This can be fixed by using proprietary wood-to-timber repair products. The market for replacement windows rests on the belief that older windows are old and beyond economical repair, but they are able to be maintained with a little attention. However, these repairs can be costly and cause substantial disruption to the home. To prevent this homeowners, many opt for a complete replacement with PVC-u windows from one of the large “one stop shop” installation companies. They can replace all windows in a home in one day, saving time and eliminating the need for different tradesmen to coordinate. They can also be supplied with energy-saving double-glazing, which can achieve higher energy efficiency ratings than those offered by traditional windows with sash. However these double-glazed units are unable to duplicate the proportions and section of historic timber sashes. 3. Security It is possible to secure traditional windows without compromising their style. Ironmongery such as mortice bolts, sash chain and sash lock could be put in place. They can be positioned in a manner that the window can be opened to allow ventilation and cleaning. These products are often not noticeable since they are designed to work with sash windows. They can be used with traditional sash window catches. These should be replaced with more robust models, such as ones that have double screws or spring levers to decrease the chance of being hit with hammers. Sash-window frames were constructed from slow-growing deal or, in more luxurious homes, from oak. When glazing bars have survived they should be kept, and if it is possible, the timber of the cill should be replaced by the same wood. Many PVC-U companies offer a one-stop shop installation service. They can take out and replace windows throughout a home in a single day, without involving other tradespeople. 4. Ventilation Sash windows were first introduced in the 17th century and allowed for a significant amount of light to enter buildings. At the end of the 18th century, they were modified so that more light could be let into the rooms. Larger glass panes were also created. The result was a lighter appearance and windows that were more elegant. Sash windows were introduced and required a new type of ironmongery. Early pulleys were of wood, later Victorian ones could be made of brass or a combination of lead and wood, and there were various types of shutter hinges and knobs. The ironmongery pieces need to be kept clean and preserved in order to appreciate their exquisite design. Timber windows require careful maintenance to keep them in good shape. Inattention to maintenance can result in: Sashes that do not slide effortlessly. holes in the frame that allow water, which can cause damage and decay. The putty can be soaked by water and cause decay to the frame or cause cill. In the I920s and I930s, steel casement windows increased in popularity due to their strength, slim and cheap, and complemented the vogue for healthy living. However, research has shown that traditional softwood sash windows can be just as efficient in thermal efficiency as double-glazed PVC-u windows and are more attractive than the sleek lines of contemporary casement windows. The industry of replacement windows did a lot to convince homeowners that their old windows were rotten and drafty. They were also beyond the budget for repair. Many old timber windows can be repaired and used for many more years with minor repairs. 5. Maintenance The traditional sash windows require regular maintenance and inspection. Failure to do this can lead to the sash cords breaking, a lot of wear on the glazing bars, and degradation of the paint and putty. The removal of sashes could also result in structural movement within the frame that causes the sash to move out of alignment and in a position that it is not able to close properly. It is also possible for the sash to be snagged or slammed into an open position and let water and draughts enter the property. The damage to timber windows is usually caused by moisture infiltration. This can be prevented by regular repairs as well as thorough painting, and then removing the source of dampness. Wet rot is recognisable by the wavy look of the existing paint which can be stripped to reveal rotting, soft timber. Any rotten timber sections must be removed and the affected part carefully cut or pieced with replacements made from the same type of wood as the ones that remain. This method of repair maximises the amount of fabric left, and is one of the least invasive methods of treating decay caused by timber. A wood condenser that is based on resin is an alternative to traditional process of sanding or staining. It is brushed on the surface of the wood to help stabilize it and shield it from further damage. It is particularly useful for the treatment of pulleys and sash cords where it can help to stop breakage. It is important that any historic ironmongery such as sash stay and latches are kept and restored rather than replaced. These items are difficult to replace without harming the the original design. It is also recommended that modern fittings made of aluminium, such as sashlifts and chainstays, be avoided as they can cause corrosion and deterioration of timber frames and sashes.
