How to Restore Timber Sash Windows in Cambridge

Many homes in Cambridge have sash windows that are traditional and the homeowners are proud of their appearance. Sash windows can get stuck and are difficult to open or shut. This is often due to moisture which can cause the timber to swell.

Box sash windows were traditionally operated using chains or cotton cords, as well as lead weights. Modern sash windows feature hidden springs to address this issue.

1. Aesthetics

In contrast to PVC-u windows, which are made to modular imperial sizes, timber sash windows can be restored to their original sizes. This lets the restoration meet the current energy standards while still complying with conservation area regulations. It also gives a window with a far more attractive appearance than uPVC alternatives.

Sliding sash window frames were initially intended for large structures or public buildings. However the production became cheaper and artisans could create larger frames using more glass. By the late 18th century sash windows were the dominant Wooden Windows And Doors Cambridge (Maps.Google.Vg) design in most British homes. Because they were simple to open, sash windows let light into rooms without the need for curtains.

The early windows were made of clear glass however, by the 17th Century, sash windows began to become more attractive. They were initially made of colored glazing bars, also known as mullions. They were expensive initially, but as glass production became cheaper and more efficient, they were a common feature in many historic homes.

In the 19th century, it was possible to make large, sturdy glasses that did not require support bars. This allowed the frame to be enlarged and, in turn, gave a better view. This was a very important innovation.

The introduction of the double-hung sliding sash was another significant improvement that came about towards the end of the I920s and beginning of the I930s. This allowed both the upper and lower sash to be opened at the same time and also improved the ventilation of a building.

Oak was used for older examples and for more prestigious buildings. A parting bead separates the two sashes and it is vital that it is maintained in order to avoid rattles and drafts. The idler wheels, sash pulleys and sash rollers are vital for the proper operation of the window.

2. Energy efficiency

As clearer and larger sheets of glass became available, sash window began to replace hinged casements. They were glazed with plate glass placed within timber frames with rebates and secured with glazing sprigs, with putty on both sides to create a watertight seal. This form of glazing gradually superseded the leaded light bulbs.

Sashes were introduced, which resulted in increased demand for ironmongery. The most common fittings included brass pulleys (and later cast-iron) weights, sash stoppers shutter hinges and handles as well as various fasteners used to secure the sashes. They were often decorated with motifs, inscriptions, and designs that were engraved to identify the maker.

With regular maintenance, sash windows are extremely energy efficient. If they are not maintained, they can become draughty. Paint and putty can cause draughts too. It is possible to fix this issue by using wood-to-timber solutions.

The industry of replacement windows is based on the belief that traditional windows are rotten and beyond economical repair, while they can be maintained with a little attention. However, these repairs can be costly and cause considerable disruption to the home. Many homeowners opt to replace their windows with PVC-u from a huge "one-stop shop" installation company. They can replace all windows in a home in one day, thereby saving time and eliminating the need for different tradesmen to coordinate. These windows can be equipped with energy-saving' double glazed door seal repairs glazing to achieve higher energy ratings than the traditional sash window. Double-glazed windows aren't capable of resembling the proportions and sections of sashes from old timber.

3. Security

It is possible to secure windows that are traditional without compromising on their aesthetics. Ironmongery like sash chain, mortice bolts, and sash lock can be installed. They can be fitted to ensure that the window is open to allow ventilation repair cambridgeshire or cleaning. They are usually unobtrusive as they are designed to complement sash windows. They can be used alongside traditional sash-window catchers, which should be replaced with more robust versions (such ones that have double screws) or spring-loaded levers to minimize the risk of them being hammered out.

Sash-window frames were traditionally constructed from slow grown deal or, in more elegant homes they were made from oak. If glazing bars have survived, they should be kept, and where it is possible, the timber of the cill should be replaced by identical wood. PVC-U companies usually offer a one stop shop installation service, removing and replacing windows on an entire home in a single 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 significant amount of light to be absorbed into buildings. At the end of the 18th century, they were adapted to allow even more light into rooms and bigger glazing panes started to be manufactured. The result was a lighter appearance and windows with more elegance.

Sash windows were introduced and required a new type of ironmongery. The first pulleys were made of wood, later Victorian ones were made from brass or a combination of lead and wood and there were various types of shutter hinges and knobs. These ironmongery pieces should be kept clean and preserved in order to appreciate their beautiful design.

Timber windows require regular maintenance to ensure they remain in good order. Lack of attention to them regularly could lead to:

Sashes that don't slide smoothly.

Holes in the frame that allow water to get in and cause decay and damage.

Water can penetrate the putty and cause decay to the frame or cause cill.

In the I920s and I930s steel casement windows gained popularity because they were strong slim and inexpensive, and complemented the vogue for healthy living. However, research has revealed that traditional softwood sash windows are just as thermally efficient 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 has done a great job convincing homeowners that their old windows were rotten, drafty and beyond economical repair. Many old windows made of timber can be repaired and used for a long time with minor repairs.

Traditional sash windows require 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 could also cause the paint and putty to deteriorate. The removal of sashes could also result in structural movement within the frame that causes the sash to move out of alignment and not closing properly. It is also possible for the sash be stuck or fixed in an open position, which can let water and draughts in the structure.

Moisture penetration is a frequent cause of damage to windows made of timber. This can be prevented by thorough painting, periodic repairs and the elimination of the source of dampness. Wet rot can be identified due to the wavy appearance of the paint that can be stripped to reveal soft, rotting timber. The sections of timber that are rotten should be carefully removed, and the affected area should be snared together or glued together using replacements of the same nature as the rest of the timber. This method of repair maximizes the amount of fabric used in the first place and is among the most minimally invasive methods of treating wood-to-timber rot.

The use of a wood consolidant made from resin is a different option to traditional sanding and staining. The product is brushed on to the surface of the timber to stabilize it and shield it from further damage. It is particularly useful in the treatment of sash cords and pulleys which help stop breakage.

It is important that any historic ironmongery like sash stays and latches are kept and rehabilitated instead of being replacing them. These items are difficult to replace without harming the the original design. It is recommended that the use of modern aluminium fittings such as chain stays and sash lifts is avoided whenever possible since they can cause corrosion and deterioration of frames and sashes made from timber.
