The Most Underrated Companies To Follow In The Sash Windows Cambridge Industry How to Restore Timber Sash Windows in Cambridge    Many homes in Cambridge have sash windows that are traditional and homeowners are proud of the way they look. However, sash windows can get stuck and be difficult to open or close. This is usually due to moisture, which can cause the wood to swell.    Traditionally, window boxes utilised chains, cotton cords or lead weights to operate. Modern sash windows come with hidden springs to solve this issue.    1. Aesthetics    In contrast to PVC-u windows, which are constructed to modular imperial sizes Timber sash windows can be restored to their original sizes. This allows the restoration of timber sash windows in order to meet the current energy requirements and conform to conservation regulations for areas. It also offers windows that are superior to the uPVC options.    Sliding sash window frames were initially only used for large buildings or public buildings. However this changed as production became cheaper and artisans could produce larger frames with more glass. In the late 18th century sash windows were the dominant wooden design in most British homes. Because they were simple to open sash windows allowed light into rooms without the need for curtains.    The early windows were made of plain glass however, by the 17th Century, sash windows began to become more ornamental. They started with coloured glazing bars, also known as mullions. They were expensive at first, but as glass production became less expensive and more efficient, they became commonplace in many homes of the period.    In the 19th century, it was possible to produce large, strong glasses that didn't need support bars. This allowed for the frame to be made bigger and, in turn, gave an improved view. This was an important innovation.    The introduction of the double-hung sliding sash was another significant improvement that came about in the I920s and beginning of the I930s. This allowed both the lower and upper sash to be opened at the same time and gave improved ventilation to the building.    The most common type of sash is made from slow grown deal (pine) but oak was utilized in more prestigious buildings and in some earlier examples. A split bead divides the two sashes, and it is important that this is well maintained to prevent rattles and draughts. The idler wheels, sash pulleys and sash rollers are essential to the functioning of the window.    2. Energy efficiency    Sash windows replaced hinged cases as clearer and larger sheets were made available. They were coated with plate glass that was placed within timber frames with rebates and pinned in place using glazing sprigs, and then putty on both sides to ensure they were watertight. This kind of glazing gradually replaced leaded lights.    Sashes were introduced, which led to a greater demand for ironmongery. The most basic fittings were brass pulleys (and later cast-iron) weights as well as sash stoppers shutter hinges and handles, and a variety of fasteners used to secure the sashes. These were often decorated with motifs, inscriptions and engraved patterns that identified the maker.    Sash windows can be very energy efficient if they are maintained regularly. However, if they are not maintained, they may become drafty and let in cold air. Paint and putty may cause draughts too. You can fix this problem by using wood-to-timber products.      The industry of replacement windows relies heavily on the notion that older windows are beyond repair and therefore cannot be maintained economically. However, they can easily be maintained with a bit of attention. These repairs can be costly and cause many disruptions in the home. To avoid 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 a single day, saving time and avoiding the need for various tradesmen to coordinate. These windows can be equipped with energy-saving' double glazing to achieve higher energy ratings than traditional windows made of sash. These double-glazed windows aren't capable of resembling the proportions and section of sashes from old timber.    3. Security    It is possible to secure windows that are traditional without compromising their style. A variety of ironmongery types can be installed with sash chains, mortice bolts, and locks for sash. These can be put in place to ensure that the window remains able to be opened for ventilation or for cleaning. These products are often not noticeable since they are designed to complement sash windows. They can be utilized in conjunction with traditional sash-window catches that are required to be replaced with more robust versions (such as those incorporating double screws) or spring-loaded levers to minimize the risk of them being hammered out.    Sash-window frames are traditionally made of oak or slow-grown deal. Where glazing bars have survived they should be preserved, and if it is it is possible, the timber of the cill should be replaced with matching wood. PVC-u companies typically provide a one-stop shop installation service, removing and replacing windows across a home in a single day without the need to involve other tradespeople or co-ordinate various visits from 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. At the end of the 18th century they were altered to allow even more light into rooms, and larger glass panes began to be produced. The result was a lighter appearance and windows that were more elegant.    The introduction of sash windows also required the creation of a new line of ironmongery. Early pulleys were made of wood. Later replacement windows cambridge were made of brass or a combination of wood and lead. There were also different types of shutter hinges and knobs. These ironmongery pieces must be cleaned and preserved to appreciate their exquisite design.    Timber windows require regular maintenance to ensure they remain in good order. Lack of attention to them regularly can result in:    Sashes that don't slide effortlessly.    Holes in the frame that allow water to get in and cause decay and damage.    break down of the putty and allow water penetration that can lead to decay in the frame and cill.    In the I920s and the I930s steel casement windows increased in popularity due to their durability, slim and cheap and also matched the fashion for healthy living. Research has shown that softwood sash windows are just as efficient as PVC-u windows and can even be more attractive.    The industry of replacement windows has made a significant effort to persuade house owners that their traditional windows are rotten, draughty and beyond repair. Many old windows made of timber can be repaired and used for many more years with minor repairs.    5. Maintenance    A traditional sash window requires regular maintenance and inspection. Inability to keep up with this can result in broken sash cords, excessive wear on the glazing bars, and deterioration of paint and putty. The removal of the sashes can also result in structural movement within the frame which causes the sash to become misaligned and unable to close correctly. It is also possible for the sash be snagged or fixed in the open position, which can let water and draughts enter the property.    Moisture penetration is a common cause of damage to timber windows. This can be prevented with thorough painting, periodic repairs, and removing the source of dampness. Wet rot is easily identified by the wavy appearance of the existing paint which can be stripped to reveal rotting, soft timber. The sections of timber that are rotten should be carefully cut out, and the affected area should be scarfed or pieced together with replacements of the exact kind as the timber that remains. This method of repair maximizes the amount of fabric that is left and is among the least invasive methods for treating timber-to-timber decay.    The use of a resin-based wood consolidant is a different option to traditional staining and sanding. It is brushed on the surface of the timber to help 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 essential to preserve and not replace any historic ironmongery such as sash latches and stays. It can be difficult to replace these items without altering their original design. It is also advised that fittings made of aluminum, such as sashlifts and chainstays, should be avoided since they can cause corrosion and deterioration of timber frames and sashes.
