When choosing new windows, it can be hard to decide which option to go for so let’s take a look at some of the advantages and disadvantages of both types of window openings.

Inward opening windows – advantages

When you have an inward opening window, it becomes much easier to clean. You don’t need a ladder, special equipment or to hire a window cleaning. When the window is open, you can clean it quite simply without compromising your own safety.

Another advantage of this type of window is that you can use external shutters, balustrades and fly screens without worrying about needing to open windows.

If the windows are tilt turn windows, you also have flexible ventilation options too. For example, with the tilt open, you have fresh air coming in but you’re not worried about security or safety of small children and pets.

Tilt turn windows actually have increased security since they have wider frames and more hinges.

Inward opening windows – disadvantages

With an inward opening window, you would need to have space on the window sill if you intend to open the window wide as a casement window. This means that you won’t be able to put picture frames or ornaments on there.

If it’s a tilt and turn window and you only intend to have it fully open in emergency situations, this won’t be a problem.

Blinds and curtains can also pose a problem when turn windows open inwards. However, you can get blinds that clip on windows opening inwards so that they’re attached to the frame or glass and move with the windows.

If your room has limited space, an inwards opening might cause problems with where you can place furniture in your house when they’re opened fully.

Outward opening windows – advantages

These are more traditional windows that swing outwards and they’re the most popular choice for homeowners.

With an outward opening window, you can still put things on your window sill without having to remove them to open the windows. What’s more, you’ve got a wide choice of blinds, curtains and internal shutters as the opening windows won’t get in the way.

Outward opening windows – disadvantages

When windows open outwards, they’re more susceptible to the elements. Rain will get into the mechanisms, which over time can cause problems. What’s more, the frames will be more exposed to UV light from the sun with the window fully open on hot days.

If you like the idea of tilt and turn windows, the majority of these won’t be outward opening windows, which means you can’t enjoy the advantages of an outward opening window.

Another disadvantage of these windows is that it makes it harder to fit external shutters or fly screens too.

Which type of window looks the best?

Traditionally, windows opening inwards looked chunkier and weren’t as slim as outward opening windows. However, things have changed a lot in recent years.

Many places still offer inward opening windows with thicker frames, but you can get thinner frames, especially if you choose aluminium windows.

Are windows opened inwards better than casement?

Often, windows that open inwards are lower in price. They are more modern and have fittings that are easier to use.

What’s more, these windows often have better thermal insulation too. And they’re much easier to clean!
