The UK is currently experiencing some of its hottest days of the year, with heatwaves expected to continue. Several heat warnings have been issued, with some places even expected to reach 40C.

Extreme heat will cause widespread disruption in a variety of ways. While you’re relaxing on the beach or concentrating on yourself to cool down and circulate air in your home, have you considered how extreme heat can affect your front door?

In fact, during the summer heat, doors can swell, which can cause some serious problems, like jamming and not functioning properly.

 

What Effect Does Heat Have on Doors?

You may be unaware of how a heatwave could affect your doors and windows because we typically experience cold weather more frequently throughout the year. However, July and August are typically the warmest months, with occasional heatwaves causing havoc on all types of doors and windows, leaving your home security at risk.

 

Jammed Locks

Extreme heat and humidity can cause many materials to expand, especially wood. When this happens, a lock can easily become trapped in one position — and deadbolts can be particularly susceptible to this. When the door expands, it begins to put pressure on the lock which can then stop it from operating correctly, leaving your locks jammed, difficult to use, or even inoperable.

 

Door Expanding

Not only does the expanding door cause issues with the door lock, but it can also cause issues with the door itself. A uPVC door can expand significantly in the heat causing the uPVC door not to open when unlocked, either through the door becoming unaligned or the door not fitting within the frame.

 

Key Problems

When spending time outdoors during summer, your keys will most likely, at some point, be exposed to heat, which could result in them bending or twisting. This will make it impossible to use them when you go back home.

Which Doors can adapt to Weather Changes?

We are a nation that likes to talk about the weather constantly, which leaves us thinking about how it could affect us daily. So, how can you choose a door that could withstand any weather changes throughout the year? Careful considerations should be taken, and the best solution when purchasing a new door is to call a local locksmith who will respond to your specific needs and concerns.

 

Aluminium Doors

Aluminium doors are the most popular because they are naturally weatherproof. Unlike wooden doors, for instance, aluminium doors do not need staining or painting to make them weatherproof. Additionally, aluminium doors and windows are sturdy, resilient, and corrosion-resistant, and require little maintenance. What makes it even better is that it is usually cheaper than wooden doors, saving you some extra money.

 

Do Aluminium Doors Expand in Heat?

Timber and uPVC doors can expand in heat, whereas Aluminium doors are much more stable and due to the structure cannot expand in a way to cause difficulty in operating.

 

Wooden Doors

With heat and direct sunlight, the finish on a wooden door can crack and fade leaving your door looking worse for wear. To help with protecting your door, you could consider painting it a lighter colour as it will absorb less light than a darker colour. This means that the door itself will absorb less light and therefore heat, keeping your door cooler.

You can also add an external varnish to the door to add a protective layer to the door, sealing in the paint and the finish to ensure a higher durability. We suggest a varnish with a high UV protection for maximum protection against UV Rays.

 

Composite & uPVC Doors

Composite and uPVC doors are easy to maintain in the sense they it is advised that they are simple wiped down with lightly soaped water once a month to remain pristine. This practise is advised to be a regular routine but can also be used in order to protect your door from the heat. Should you find your door getting hot, you can simply wipe it down with cool, but not freezing water, in order to lower the overall temperature of the door and keep it in a manageable state.

How Does the Summer Weather Affect my Door?

Brilliant sunshine, high temperatures and high humidity can cause much strain on your doors leading to swelling, faded paint, bleaching and in extreme cases cracking. Not taking proper care of your doors in the heat can seriously impact your home security and the durability of your door.

Sometimes when in heat, materials can expand causing mechanisms to misalign, doors not to lock and handles to jam which is not only a nuisance but also can leave you with a bill should you need to call someone out.

What Type of Door is Best for Direct Sunlight?

Arguably factors such as budget and practicality will need to come into play when choosing a door. But the best doors for durability in direct sunlight are either composite or aluminium doors. Both door materials are renowned for being low maintenance and extremely durable and one of the many benefits that they have is that the colour of them is not applied to the surface but rather under many different vanishes and coatings.
