Can Home Windows Crack From Cold Weather?

Can home windows crack from cold weather?

Can home windows crack from cold weather is a common question we are asked here at Park Lane. Understandably, it is a big concern as a cracked window is not just a way to lose heat but also poses a threat to home security and safety. Let’s look at the reasons windows might crack and what can be done to prevent it happening.


Why does a window crack?

Windows can crack for a variety of reasons, but cold weather can be one of them.

The most common reason this happens is due to the difference in temperature on either side of the window. When it is cold outside but hot inside the house, the thermal difference can cause cracks.

The good news is that the temperature difference would have to be quite significant for cracks to form. Here in the UK, it is not that common for the temperature outside to be so vastly different from the temperature inside. A big temperature difference could happen if the sun suddenly shines on a very cold window, such as at sunrise. That is a very specific set of circumstances however so again, it isn’t that common.

The other reason the cold might cause a crack in a window is if it is just extremely cold. In places like Canada where the winters are much worse than in the UK, it is a more common occurrence.


What causes windows to crack?

Other reasons windows can crack are due to the manufacturing and quality of the window.

When windows are installed, they can be affected by the temperature or humidity in that environment. This means it is important they are manufactured in a place with environmental controls. The window and glass will be much less susceptible to environmental factors if they are.

The materials of that make up the whole window also need to be of a high standard. If cheap or substandard materials are used this can create problems after installation. Warping, cracking and condensation are all fairly common problems from poorly made windows.

Window manufacturers add a desiccant, which is a type of moisture absorbing material, into the windows as they are made. Substandard window makers may use a cheaper, less effective material which will lead to moisture and condensation in the window.

If the creation of the glass and cutting it to shape is of a low standard this can lead to problems with the glass later. Imperfections might not be noticed by the buyer but even the smallest chip can become a fracture.


How can you prevent windows from cracking?

The best way to prevent windows from cracking is to buy high quality windows from a reputable supplier. Look for suppliers with excellent reviews from customers and accreditation from industry bodies. Suppliers who have a warranty or guarantee on their windows may be more likely be selling quality windows too.

It is also important to keep your windows in good condition. Inspecting them regularly, especially over winter, will bring any problems to your attention quickly. It is possible to repair some minor issues with a window before they become big problems.
