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 get stuck and become difficult to open and close. This is typically due to moisture, which can cause the wood to swell. Box sash windows were previously operated with chains, cotton cords and lead weights. Modern windows with sash springs are concealed to eliminate this issue. 1. Aesthetics Contrary to PVC-u windows which are manufactured according to imperial sizes that are modular Timber sash windows can be restored to their original dimensions. This allows for the restoration of timber sash windows to comply with current energy standards and conform to conservation area regulations. It also offers a window with a far superior appearance than uPVC alternatives. Sliding sash windows were initially only found in large buildings or public buildings, though this changed as production was less expensive and craftsmen were able to create larger frames using more glass. At the close of the 18th century, sash windows were the most popular wooden design in British homes. Because they were simple to open, sash windows let light into rooms without curtains. Early windows were simple glass but by the 17th century sash windows started to become more decorative, with coloured glazing bars and moulded mullions. These were very expensive at the time, but as glass production improved and cheaper they became a part of numerous period houses. In the 19th century, it became possible to make large, sturdy glasses that didn't require support bars. This allowed the frame to be made bigger, which in turn gave an improved view. This was an important 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 is another important improvement that was made at the end of the I920s, and at the beginning of the I930s. Oak was used for older examples and more prestigious buildings. A split bead divides the two sashes, and it is vital that it is maintained to prevent rattles and draughts. It is also essential that the idler and sash pulley wheels are kept in good shape as they aid in operating the window. 2. Energy efficiency As clearer and larger sheets of glass became available, sash window started replacing hinged casements. Plate glass was set into rebated timber frames, pinned with glazing sprigs and putty was sprayed on the frame's sides for watertightness. This kind of glazing gradually replaced the leaded light bulbs. Sashes were introduced, which resulted in an increase in demand for ironmongery. The basic fittings included brass pulleys (and later cast-iron) weights as well as sash stoppers shutter hinges, handles and shutter hinges as well as a variety of fasteners used to secure the sashes. They were often decorated with designs, inscriptions, and patterns engraved to identify the maker. Sash windows can be very energy efficient when they are maintained regularly. If they are not maintained they can get draughty. Draughts can also result from the degeneration of putty and paint. You can fix this problem by using wood-to-timber products. cambridge doors and windows for replacement windows rests on the assumption that old windows are damaged and beyond repair, while they are able to be maintained with a bit of care. However, repairs to these windows can be costly and cause significant disruption to your home. Many homeowners opt to replace their windows using PVC-u from a huge “one-stop shop” company for installation. They can replace all windows in a home in one day, saving time and avoiding the need for different tradesmen to coordinate. These windows can be fitted with 'energy-saving double-glazing to attain higher energy ratings than traditional windows with sash. Double-glazed windows aren't able to replicate the proportions or section of the sashes made of timber from the past. 3. Security Traditional windows can be made secure without compromising their aesthetics. Ironmongery such as mortice bolts, sash chain and sash locks can be used. They can be fitted in a way so that the window can still be open for ventilation and cleaning. They are generally minimal in appearance, as they are designed to complement the sash window. They can be used in conjunction with traditional sash window catches. These should be replaced with more robust versions like those with double screws or sprung levers in order to reduce the possibility of being struck by hammers. Sash-window frames are typically made from oak or slow-grown deal. If the glazing bars are in good condition and are not damaged, they should be left. If it is feasible, the cills made of timber should be replaced by wood that is in line with. PVC-u companies typically provide a one-stop shop installation service, which includes removing and replacing windows on an entire house in a day without the need to involve other tradespeople, or coordinate visits from a number of different suppliers. 4. Ventilation Sash windows were introduced in the 17th century and allowed for a huge amount of light to be absorbed into buildings. In the 18th century, they had been modified so that more light could be let into rooms. Larger glass panes were also created. The result was a much more streamlined appearance, and windows with a higher degree of elegance than before. The introduction of sash windows also necessitated a new range of ironmongery. Early pulleys were constructed from wood. Later Victorian ones were made of brass or a combination of wood and lead. There were also different kinds of knobs and shutter hinges. The ironmongery components should be maintained and cleaned so that the quality of their design can be appreciated. Timber windows require careful maintenance to ensure they remain in good condition. Inattention to maintenance routinely could result in: Sashes that no longer slide easily. Holes in the frame that allow water to enter and cause decay and damage. break down of putty allowing water penetration that can lead to decay in the frame and cill. In the I920s and I930s steel casement windows increased in popularity because they were strong slim and inexpensive and also matched the fashion for healthy living. However, research has shown that traditional softwood sash windows are just as thermally efficient as double-glazed windows made of PVC-u, and may be more appealing than the modern sleek design of casement windows. The replacement window industry has done a great job convincing homeowners that their old windows were rotten and drafty. They were also beyond the budget for repair. Many older timber windows can be fixed and used for many more years with minor repairs. 5. Maintenance Traditional sash windows require regular maintenance and inspection. If you don't maintain your window's sash, it could cause the sash cords breaking and the glazing bars wearing out excessively. It can also cause paint and putty deteriorate. The removal of sashes could also result in structural movement within the frame which causes the sash to be misaligned and unable to close correctly. It is also possible for the sash to be snagged or fixed in an open position and this can let water and draughts in the structure. Moisture penetration is the most common cause of damage to timber windows. This can be avoided by regular repairs by thorough painting and eliminating the cause of dampness. The paint can be removed to expose the soft, decaying wood. Any rotten timber sections should be cut out and the affected part carefully scarfed or pieced in using replacements made from the same kind of timber as the ones remaining. This method of repair maximizes the amount of fabric that was originally used and is among the most non-invasive methods to treat wood-to-timber rot. A wood condenser made of resin is an alternative to the traditional process of sanding or staining. It is brushed on the surface of the timber to stabilize it and shield it from further damage. It is especially beneficial for treating sash and pulley cords, which can help prevent breakage. It is important to restore and not replace any old ironmongery, such as stay latches and sash latches. These items are difficult to replace without damaging the quality of the original design. It is recommended that the use of modern aluminium fittings, such as chain stays and sash lifts is avoided if at all possible as they can cause corrosion and deterioration to timber frames and sashes.
