How to Restore Timber Sash Windows in cambridge windows and doors

Many homes in Cambridge have sash windows that are traditional and the homeowners are proud of their appearance. Sash windows can become stuck and are difficult to open or close. This is usually due moisture which can cause the wood to expand.

Box sash windows were historically operated by chains or cotton cords, as well as weights made of lead. Modern sash window springs are hidden to solve this problem.

1. Aesthetics

Timber sash windows, unlike PVC-u windows, which are made in imperial sizes, which are modular, can be restored to their original size. This permits the re-installation of timber sash windows to meet the current energy requirements and to comply with conservation area regulations. It also provides a window with a far superior appearance than emergency upvc locksmith cambridge Door repairs (scientific-programs.science) alternatives.

Sliding sash windows were originally only used in large structures or public buildings, however this changed when production became less expensive and craftsmen could make larger frames with more glass. By the late 18th century Sash windows were the most popular design of wood in the majority of British homes. Sash windows were easy to operate and let light into rooms without the use of curtains.

The first windows were made of plain glass, but by the 17th Century, sash windows began to be more decorative. They started with coloured glazing bars or mullions. They were expensive at the time but as glass production improved and cost-effective, they became a part of many of the period homes.

In the 19th century, it was possible to make large, strong glasses that didn't need supporting bars. This allowed the frame's size to increase more, which in turn allowed for a wider view from the window. This was a significant improvement.

The introduction of the double-hung sliding sash is another important improvement that was made in the I920s and 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 essential that the idler and sash pulley wheels are in good shape as they assist in operating the window.

2. Energy efficiency

As clearer and larger sheets of glass became available, sash windows began replacing hinged casements. Glass plates were set in frames made of timber, which were secured with glazing sprigs and putty was then sprayed onto both sides of the frame to ensure watertightness. This form of glazing gradually superseded led lights.

Sashes were introduced, which led to increased demand for ironmongery. The most common fittings included brass pulleys (and later cast-iron) weights as well as sash stoppers shutter hinges, handles and shutter hinges, and a variety of fasteners used to secure the sashes. These were often decorated in designs, inscriptions, and patterns engraved to identify the maker.

Sash windows can be very energy efficient when they are maintained regularly. However, without this maintenance they can become drafty and let in cold air. Draughts can also result from the degeneration of paint and putty. This can be corrected making use of wood-to-timber repair tools that are proprietary.

The replacement window industry relies heavily on the notion that old windows are beyond repair and cannot be maintained economically. However, they can easily be maintained with a little attention. However, repairs to these windows can be costly and cause substantial disruption to the home. To prevent this homeowners, many opt for a complete replacement with PVC-u windows made by one of the largest "one-stop shop" installation companies. They can replace and remove all windows in a home in just one day, eliminating the need to coordinate multiple tradesmen and making the entire process much faster. They can also be fitted with 'energy saving' double-glazing to achieve more energy efficient ratings than traditional windows with sash. These double-glazed windows aren't capable of resembling the proportions or section of sashes from old timber.

3. Security

It is possible to secure windows that are traditional without compromising their appearance. Ironmongery like mortice bolts, sash chain and sash locks can be used. They can be fitted in a manner that the window is able to be opened to allow ventilation and cleaning. They are generally not noticeable, since they are designed to complement the sash window. They can be utilized in conjunction with traditional sash window catches that should be replaced with more robust versions (such ones with double glazing repairs near me screws) or spring-loaded levers to minimize the risk of them being hammered open.

Sash-window frames are typically made from oak or slow-grown deal. If the glazing bars remain in good condition, they should be retained. If feasible, the cills made of timber should be replaced by wood that matches. Many PVC-U companies offer a one-stop installation service. They can remove and replace windows throughout a home in a single day, without involving other tradespeople.

4. Ventilation

Sash windows were introduced in the 17th century and allowed for a significant 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 bigger glazing panes started to be manufactured. The result was a much more streamlined appearance, and windows that had a higher quality of design than before.

The introduction of sash windows also necessitated an entirely new range of ironmongery. The first pulleys were made of wood, while later Victorian ones could be made from brass or a combination of lead and wood and there were many kinds of shutter hinges and knobs. These ironmongery elements should always be retained and cleaned down to ensure that the exquisite quality of their design can be appreciated.

To ensure they remain in good shape, timber windows require regular maintenance. Inattention to maintenance can 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, which could lead to decay of the frame and cill.

Steel casement windows were popular in the I920s and I930s because they were strong and slim, cost-effective and matched the trend towards healthy living. However, research has proven that traditional softwood sash windows can be just as efficient thermally as double-glazed windows made of PVC-u, and can be more attractive than the modern sleek design of casement windows.

The replacement window industry was able to convince homeowners that their old windows were decayed drafty, noisy and beyond repair. Many old timber windows can be repaired and used for many more years with minor repairs.

5. Maintenance

A traditional sash window needs regular maintenance and inspection. If you do not maintain your window's sash, it could lead to the sash cords breaking, and the glazing bars wearing out excessively. It can also cause paint and putty to become damaged. The removal of sashes can also result in structural shifts within the frame, which causes the sash to be misaligned and in a position that it is not able to close properly. It is also possible for the sash be snagged or fixed in an open position, which can let water and draughts into the property.

Damage to windows made of timber is often caused by water infiltration. This can be prevented with thorough painting, periodic repairs and the elimination of the cause of dampness. The paint can be removed to reveal the soft, rotting wood. Any timber that is rotting should be cut off and the affected area carefully cut or pieced with replacements made of the same type of wood as those remaining. This method of repair maximizes the amount of original fabric that is left and is one of the least invasive methods for treating decay caused by timber.

The use of a wood consolidant made from resin is an alternative to traditional staining and sanding. The product is brushed on the surface of the wood to protect it and stabilize it. It is particularly useful for the treatment of sash and pulley cords, which can stop breakage.

It is essential that any historic ironmongery such as sash stays and latches be kept and restored instead of replaced. It is difficult to replace these items without altering their original design. It is also advised that fittings made of aluminum like sashlifts and chainstays, should be avoided since they can cause corrosion and deterioration of timber frames and sashes.
