Considering Sliding Sash Windows

By Mark Berg


There are many types of window on modern properties, sliding sash are the more traditional wooden windows, different from the plastic window frames that are on many modern houses.

A sliding sash widow typical consist of two sashes (sashes are the frame that holds the glass panes) that open by being pushed up or pulled down in a vertical manner. The lower sash typical is on a runner that is in front of the upper sash whilst the upper sash is on a runner that is directly behind the lower sash. Therefore when opened the lower sash rises up in front and the upper sash lowers behind so both sashes are able to be opened at the same time.

Because not every home is fitted with sliding sash windows when someone buys an older home or perhaps rents a flat with this window design it can be puzzling on how these windows work and the proper way to open and close them. By not operating these windows properly they can become damaged and broken.

The proper way to open this type of window equal pressure needs to be applied with both the left and right hand or the window can become "jammed" at a slanted position. To close them apply the same equal pressure with two hands and slowly lower the sash. Because wood swells in inclement weather such as rain there are times when the window can be difficult to open or close and can become stuck in that position.

To maximize the efficiency of these windows and get the best air circulation within the home it is best to raise the bottom sash half way whilst lowering the top sash half way. Because hot air rises, the hot air within the home will leave through the top opening of the window whilst the cool air from outside is being drawn in through the bottom opening of the window.

Occasionally the bars and sashes will require a fresh coat of paint to keep them looking clean or to match a new d'ecor within the room. After removing the old paint (taking special care if the old paint is lead based) tape off the glass panes and use a fine brush to paint the bars and sash. Once dry just remove the tape.

Besides washing the window panes occasionally the bars and window sashes will need to be repainted. Lead paint needs to be removed properly so led particles do not become air borne. Once the old paint is removed tape off the glass panes and use a thin brush to repaint the wooden surfaces and when dry just remove the tape.

These windows can become quite drafty over the years but there are many products that can be purchased in home improvement stores such as felt stripping that will cure this problem. Many of these products can be applied by the average homeowner.

When restoring an older home the aesthetic value of the home is kept intact by using replacement sliding sash windows. Not only does it protect the original beauty of the home but it also increases the monetary or resale value.
