1. Aesthetics
In contrast to PVC-u windows, which are manufactured according to imperial sizes that are modular the timber sash windows are able to be restored to their original size. This allows the restoration of timber sash windows to comply with current energy standards and to comply with conservation regulations for areas. It also offers windows that are superior to uPVC options.
Sliding windows with sash were initially only used for large buildings or public buildings. However the production became cheaper and artisans could make larger frames using more glass. In the late 18th century Sash windows were the most popular wooden style in a majority of British homes. Because they were simple to open sash windows allowed light into rooms without the need for curtains.

Sash-window frames were typically constructed from slow-growing deal or, in the more luxurious homes made of oak. If glazing bars have survived, they should be kept and if it is feasible, the wood of the cill should be replaced with matching wood. Many PVC-u firms offer a one-stop shop installation service. They can take out and replace windows on a complete home in a single day, without the need to involve other tradespeople.
4. Ventilation
Sash windows were first introduced in the 17th century and allowed for a huge amount of light to enter buildings.

The result was a much lighter appearance and windows with a greater degree of elegance than before.
Sash windows were introduced that required a brand new type of ironmongery. The first pulleys were made of wood, whereas later Victorian ones could be made of brass or a combination of lead and wood and there were a variety of shutter hinges and knobs. The ironmongery pieces need to be maintained and cleaned to appreciate their exquisite design.
To ensure they remain in good condition, timber windows need to be maintained. Lack of attention to them regularly can result in:
Sashes that no longer slide easily.
holes in the frame that allow water that can cause decay and damage.
break down of putty, allowing water penetration, which can lead to decay in the frame and cill.

The sash may also become stuck in its open position, allowing the water and drafts to enter the building.
Damage to timber windows is usually caused by moisture entry. 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. The sections that are rotting should be carefully removed, and the affected area should be snared together or glued together using replacements of the same kind as the timber that remains. This method of repair increases the amount of fabric that was originally used and is one of most non-invasive methods to treat wood-to-timber rot.
