Sliding vs Awning Windows: Which Is Best for Your Home?

Installing new windows means making a choice between types, which involves considering their looks, cost, overall efficiency and practicality. Often, the choice is between sliding and awning windows. The former have been popular for many years while the latter are increasing in popularity. To decide which is best for you, it is necessary to consider all the features carefully.

What are Sliding Windows?

Sliding windows consist of at least two panels, one of which will be fixed while, depending on the width of the area covered, one or more panels are opened by sliding them along a track behind the fixed panel. It is possible to have a vertical arrangement although horizontal configurations are by far the most common. Modern sliding window designs glide smoothly along the track with minimal effort.

What are Awning Windows?

Awning windows are hinged at the top and open outwards from the bottom so they form a small awning or protective cover that prevents rain getting in. They are generally operated using a crank handle so they are easy to use and will usually open up to a 45 degree angle.

Pros & Cons of Sliding Windows

Sliding windows have a number of benefits when compared to awning windows:

• There is no protrusion when opening them since they slide behind a fixed panel rather than opening outwards or inwards. That means they are ideal for any room where space is limited.
• They have a relatively simple mechanism, with no hinges, springs or pulleys, and are therefore relatively easy to maintain. The main requirement is to keep the track clean so the opening windows will slide easily.
• Modern sliding windows feature multi-point locking systems and toughened glass.
• Operation is simple, moving the windows from side to side along a track to open and close.
• The windows can easily be cleaned both inside and outside, even on high floors. Many have lift-out or tilt-in panels so can be cleaned from either side.
• Because they have fewer components, sliding windows are often cheaper to buy than awning windows.
• Whereas awning windows are limited in size, sliding versions can cover a wide area by using multiple panels.

Sliding windows also have a number of drawbacks that need to be taken into consideration:

• If they are pulled from side to side regularly when opening and closing and insufficient care is taken, this can cause wear and the sash may become warped.
• Sliding windows are not as airtight or energy-efficient as awning models because the weather stripping used is not as good as compression seals. The method is also not as durable so efficiency will decrease over time, resulting in draughts when closed. To achieve an equivalent level of energy efficiency, it may be necessary to upgrade glazing and seals.
• Protective fly screens are placed on the exterior and so are exposed to the weather and are likely to be affected by dirt and debris.
• Although the windows provide excellent security when closed, they cannot be secured when partially open so they are less versatile in terms of security.
• Due to the lack of compression seals, they do not have the same level of noise insulation and may let more outside sound through when closed.

Pros and Cons of Awning Windows

The design of awning windows gives them a number of advantages:

• Their superior sealing provides better insulation so they reduce noise levels and heat loss and gain when closed, making them more energy-efficient.
• A multi-point locking system allows them to be locked when partially open or closed so they can provide ventilation without compromising security. This also means windows can be locked when partially open on high floors with no danger for young children
• Ventilation is possible even during periods of rain because the window provides a protective awning when open, keeping the moisture out.
• Operation is simple due to the crank handle, even for windows that are placed at height.
• A fly screen can be placed on the inside and so is protected from external dirt and damage.

There are, however, some drawbacks:

• The more complex design and relatively large number of components make awning windows about 20% more expensive than sliding models.
• Although interior cleaning is simple, exterior surfaces will be much harder, especially on high floors where a ladder may be needed.
• Size is generally limited to about fifty inches wide so they may not suit spaces requiring wide, unobstructed views.
• Opening is limited compared to sliding windows so ventilation may not be as good.
• A certain amount of clearance is needed to open the windows so they may not be suitable where space is limited. This is especially important in walkways or narrow areas where an open window may obstruct movement.

Which is Better for Your Home?

As with many home design choices, there is no clear winner because it largely depends on your circumstances and preferences.

Awning windows provide better energy efficiency, noise insulation and superior ventilation during wet weather. Sliding windows, however, are cheaper to buy, easier to clean, simple to operate and are better for wide openings and where space is limited.

Awning windows are often installed in bathrooms where good ventilation and privacy are essential. They are also good where access to the window is difficult, due to being placed above a work surface or high on a wall, and for climates that experience frequent rain. Sliding windows are great for wide openings where the view and natural light are important. They are also ideal for areas where space is limited and awning windows will cause an obstruction when open.

You will need to look at the aesthetics of each type and decide how they will fit in with your home. It’s all down to personal choice and individual situations but both types can be a great option.
