The Most Convincing Proof That You Need Sash Windows Cambridge
How to Restore Timber Sash Windows in Cambridge
Many homes in Cambridge have sash windows that are traditional and homeowners are proud of how they look. Sash windows can become stuck and become difficult to open or 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 sash windows feature hidden springs to solve this problem.
1. Aesthetics
Contrary to PVC-u windows which are constructed to modular imperial sizes, timber sash windows can be restored to their original dimensions. This allows the restoration to meet modern day energy requirements while still complying with conservation regulations for the area. It also offers windows that have a 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 more affordable and artisans could produce larger frames with larger glass. In the 18th century, Sash windows were the most popular wooden design in most British homes. Sash windows were simple to operate and allowed light to enter rooms without the use of curtains.
The first windows were made of plain glass, but in the 17th century sash windows started to become more ornamental. They started with coloured glazing bars or mullions. They were costly initially, but as glass production became cheaper and more efficient, they became an integral feature in many homes of the period.
In the 19th century, it became possible to produce large, strong glasses that did not require support bars. This allowed for the frame to be enlarged and, in turn, gave the viewer a better view. This was a significant advancement.
Another significant improvement was the introduction of the double-hung sliding window at the end of I920s and the beginning of the I930s. This allowed both the upper and lower sash to be opened at the same time and gave improved ventilation to the building.
The most commonly used type of sash is made from slow grown deal (pine) however oak was also used in more prestigious buildings and in some earlier examples. It is essential to keep the separation bead that divides the sashes. This will stop rattles and draughts. The sash pulleys, idler wheels and sash rollers are also vital to the functioning of the window.
2. Energy efficiency
Sash windows replaced hinged cases as larger and clearer sheets were made available. They were coated with plate glass that was placed within timber frames with rebates and secured with glazing sprigs and putty on both sides to create a watertight seal. This kind of glazing gradually replaced leaded lights.
Sashes were introduced, which led to an increase in demand for ironmongery. The most common fittings included brass pulleys (and later cast-iron) weights and stoppers for sashes shutter hinges, handles and shutter hinges and various fasteners used to secure the sashes. These were usually decorated with patterns, inscriptions and engravings to identify the maker.
Sash windows can be very energy efficient if they are maintained regularly. Without this maintenance they can get drafty. window companies cambridge and putty may cause draughts too. It is possible to fix this issue by using wood-to-timber solutions.
The replacement window industry relies on the perception that traditional windows are rotten and beyond repair, but they can be easily maintained with a little attention. These repairs can be expensive and cause many disruptions in the home. Many homeowners opt to replace their windows using PVC-u from a huge "one-stop shop" installation company. They can replace all windows in a home in one day, saving time and eliminating the need for multiple tradesmen to coordinate. They can also be fitted with 'energy-saving' double-glazing to get greater energy efficiency than are possible with traditional windows with sash. Double-glazed windows aren't capable of replicating the proportions or section of the sashes made of timber from the past.
3. Security
Traditional windows can be made more secure without compromising their aesthetics. Ironmongery such as mortice bolts, sash chain and sash lock could be put in place. These can be installed in such a way that the window can be opened to allow ventilation and cleaning. They are generally unobtrusive, as they are designed to match the sash window. They can be used in conjunction with traditional sash window catches. They are best replaced with more robust versions, such as those that incorporate double screws or spring levers, to minimize the possibility of being struck by hammers.
Sash-window frames were constructed from slow grown deal or, in the more elegant homes they were made from oak. If the glazing bars are still intact, they should be retained. Where it is possible, the cills of the timber should be replaced by timber that is compatible with. PVC-U companies usually offer a one stop shop installation service that can remove and replacing windows across a home in a single day without the need to engage other tradespeople or coordinate visits from a number of different suppliers.
4. Ventilation
Sash windows were first introduced in the 17th century and allowed for a huge amount of light into buildings. At the end of the 18th century, they were modified to allow more light could be let into the rooms. Larger glazing panes were also made. The result was a lighter appearance and windows that were more elegant.
The introduction of sash windows also required an entirely new range of ironmongery. Early pulleys were of wood, whereas later Victorian ones were made of brass or a mixture of wood and lead, and there were a variety of shutter hinges and knobs. These ironmongery elements should always be kept and cleaned so that the fine quality of their design can be appreciated.
Timber windows require regular maintenance to keep them in good shape. Inattention to maintenance routinely could lead to:
Sashes that do not slide smoothly.
Holes in the frame that allow water to get in and cause damage and decay.
Water can get into the putty and cause decay to the frame or cill.
Steel casement windows gained popularity in the I920s and I930s because they were sturdy and slim, cheap and complemented the trend for healthy living. However, research has shown that traditional softwood sash windows are as thermally efficient as PVC-u double-glazed windows, and are more attractive than the modern sleek design of casement windows.
The window replacement industry has made a significant effort to convince homeowners that their windows are old, dirty, and beyond repair. Many old timber windows can be fixed and utilized for a longer period with minor repairs.
5. Maintenance
Traditional sash windows require regular maintenance and inspection. Inability to keep up with this can lead to sash cords breaking, excessive wear on the glazing bars and the deterioration of putty and paint. The removal of sashes may also result in structural movements within the frame, causing the sash not to close properly. The sash can also be stuck in an open position, which allows water and draughts into the property.
Moisture penetration is a frequent cause of damage to timber windows. This can be prevented by regular repairs, thorough painting and removing the cause of dampness. The paint can be removed to expose the soft, rotting wood. Any rotten timber sections should be cut off and the affected area carefully scarfed or pieced in using replacements made from the same type of wood as the ones that remain. This repair method increases the amount original fabric and is one of most non-invasive methods to treat timber-to-timber rot.
The use of a resin-based wood consolidant is a different option to traditional sanding and staining. The product is brushed on to the surface of the wood to stabilize it and shield it from further damage. It is especially useful to treat pulley cords and sash, where it can prevent breakage.
It is crucial that any old ironmongery such as sash stays and latches be kept and rehabilitated instead of being replacing them. These items can be very difficult to replace without compromising the the original design. It is also advised that modern fittings made of aluminium like sashlifts and chainstays, are avoided since they can cause deterioration and corrosion of timber frames and sashes.
