Condensation On Outside Of Windows In Summer

condensation-on-outside-of-windows-in-summer

When it comes to window condensation, the seasons of most concern to homeowners are inevitably Autumn and Winter. Due to the low outside temperatures, condensation quickly occurs, forming as a result of warm and moist air getting in touch with the cold windows, frames and walls.

However, condensation can also happen during the Summer. Is it a bad sign? Or is it something normal? Many people think that condensation on outside of windows in Summer is a sign that something is wrong with their windows. Is that the reality? It’s time to find out…

Summer And Winter Condensation: The Essential Difference

Let’s start by exploring the key differences between Summer and Winter condensation. The first and main difference is Summer condensation happens on the outside of the windows. Winter condensation, on the other hand, appears on the inside of the windows.

Condensation on outside of windows in summer is mostly visual. There are no risks for your windows, or your health for that matter. Winter condensation, on the other hand, can be destructive. Inside condensation eventually results in a mould, which is a health issue by itself.

Condensation can form in both hot and cold weather. In countries with hotter climates, the temperature outside is extremely high, while the inside is heavily air conditioned to combat the heat. Consequently, condensation often appears on the windows

Condensation On windows In Summer: Key Causes

What causes condensation on outside of windows in Summer? Well, there are many contributory causes, but moisture vapour in the air is usually the first one that comes to mind.

When there is a great difference between the inside and outside temperature, moisture easily accumulates. Usually, the coldest surface in a home is the window, or more precisely, the edges of the windows where conduction is greatest.

Condensation can form in both hot and cold weather. In countries with hotter climates, the temperature outside is extremely high, while the inside is heavily air conditioned to combat the heat. Consequently, condensation often appears on the windows.

However, despite being unsightly, in terms of functionality, this is nothing to worry about.

The windows are the only protection, and if they show signs of condensation, it means they are working properly.

In most cases, a windows contractor will explain to you that energy efficient windows can have signs of condensation during the Summer. If your contractor has failed to explain this to you, do not panic; your windows are functioning effectively

Window Performance: Why It Matters

As mentioned at the beginning, when people notice condensation on outside of windows in Summer, they think their windows are not working properly. The reality is actually the opposite. Condensation is a clear sign that your energy efficient windows are working just as they should be.

Think of this for a moment. The outside temperature during Summer is always higher than the inside one. When you notice condensation, that means that your windows are working exactly as designed. They are not allowing heat from your home to go outside, and vice versa.

Exterior condensation on energy efficient windows is quite normal and common. The question is why your normal windows are not showing signs of condensation. That might be a bigger problem, as it is a sign that there is energy leakage going on.

That leakage is allowing air to move from outside to the inside. This tiny amount of air is enough to raise or lower the temperature of your home just so there is no condensation.

In addition to improving your energy efficiency, and reducing your energy bills, double glazed windows carry other benefits. One of them is acting as a sound barrier

Upgrade Your Windows The Easy Way!

Not all windows are energy efficient. Nowadays, the most energy efficient windows are double glazed windows. They are designed in a way that they do not let air pass from outside to inside and vice versa. Double glazed windows consist of two panes and a section between them, where the air is trapped.

The main benefit of double glazed windows is they reduce your energy consumption. They do not let warm or cold air pass outside. In the Summer, that means you won’t need to turn on the air conditioner as often as you normally do.

In the Winter, that means you need less gas to heat up the room, and no further heating, as the warm air stays inside.

In addition to improving your energy efficiency, and reducing your energy bills, double glazed windows carry other benefits. One of them is acting as a sound barrier.

They reduce outside noise much more effectively than single glazed windows. Your home will become an acoustic soundproof barrier, and you will be able to enjoy the peace and quiet that ensues as a result.

And an underrated benefit of double glazed windows is improved security. Studies show that burglars are less inclined to break through double glazed windows because they are a bigger challenge, and harder to break.
