How Secure Are Slimline Aluminium Doors?

Many of the questions we frequently get asked, focus on the security of our doors. Keeping your loved ones and valuables safe is a primary concern for most homeowners.

While all our doors offer a high level of security, today we are focusing on our slimline aluminium doors.

Whether you’re looking at patio doors or front or back entrance doors, slimline aluminium doors offer a high-security option to help you protect your home in style.

Smart Home Integration:

Many home and business owners are converting their properties to automation. Also known as a smart home, this is a building where security systems, lights and electrics, and heating can all be controlled remotely via a computer or smartphone.

Saving energy and increasing convenience, a smart home can also increase your security with cameras available to view on your smart device. 

A high-security front door is a key component in a smart home. Since aluminium doors can fit any space, they are easy to integrate into an existing system. Home security alarms for doors can be easily fitted to seamlessly integrate into your smart home system.

What makes Slimline Aluminium Doors doors so strong?

Aluminium is a naturally strong and durable material, making it ideal for home security doors. It is not just the raw material that makes our slimline aluminium doors strong and secure.

Security Features:

Built-in and additional security features only enhance the performance of Manchester Window Factory slimline aluminium doors. Knowing the glass can’t be smashed, the panels removed, or the locks picked, bumped, or drilled in your doors should help you sleep soundly at night and feel safe during the day.

It is not just homeowners who prioritise security. You may also need to secure your business premises. Aluminium front, back, or side entrance doors are also perfect for this purpose.

The peace of mind of knowing your home and business are protected from break-ins cannot be underestimated. With our slimline aluminium doors, you can rest assured that you and your treasured possessions are safe and secure.

Advanced Locking Mechanisms:

Home security doors are only as secure as their locking systems. At Manchester Window Factory, our home security locks for doors include multi-point locking systems and Ultion door barrels. Our locks are designed with anti-pick technology, such as indents or ridges on the internal lock pins. This makes it almost impossible to determine when the pins are at the right height, preventing the lock from being picked. 

If someone cannot pick a lock the traditional way (using a paperclip or similar to manipulate the pins) they may try to ‘drill’ or ‘bump’ the lock. Our locks include ceramic plates or steel pins and a steel cylinder to prevent a drill bit from being inserted. Bumping refers to trying to get the pins to ‘jump’ above the shear line, moving them into the cylinder to open the lock. Anti-bump locks have more pins in shallow stacks, rotating disks or no top pins and programmable side bars to stop them from jumping.

Our doors are also fitted with anti-jacking systems to prevent the lifting and removal of the glass panels to gain access. You can also incorporate our doors into your security or smart home system.

High-Quality Materials:

We only sell and install the highest-quality aluminium doors. All our aluminium doors are manufactured using high-grade aluminium.

A stronger door means a higher level of security, and our aluminium doors are weather and rust-resistant, so they won’t weaken over time.

We don’t stop at the aluminium frame, however. Our glazing options and selection of durable hardware and secure locking systems are also top-of-the-line.

Maintenance and Durability:

Another deciding factor for a lot of homeowners choosing aluminium security doors is the lack of maintenance required. Aluminium is anti-corrosive and requires very little upkeep to maintain it. You can easily clean an aluminium entrance door with warm soapy water and a soft cloth, including the glass. You may also need to check the track to ensure a smooth gliding action. Our aluminium doors are powder-coated to prevent water spots from occurring. 

The low-maintenance nature of aluminium doors and their durability make them an excellent, long-lasting investment in the appearance and thermal efficiency of your home.

Sustainability and Energy Efficiency:

The last few years have seen a move towards more sustainable manufacturing and energy-efficient solutions within the construction industry.

Consumers and manufacturers are concerned with trying to reduce our collective carbon footprint. At Manchester Window Factory, we are committed to using sustainable and responsibly sourced materials wherever possible. Here are just a few reasons why aluminium slimline doors are eco-friendly.

  • Aluminium is the third most abundant element in the world (after oxygen and silicon) and is readily available
  • Since it is much lighter than other metals, it costs less to transport and requires less fuel
  • It is built to last – saving the environmental cost of replacements 
  • It is almost infinitely recyclable. It’s believed approximately 75% of all aluminium ever is still in use
  • When it does come time to recycle your aluminium doors, you can be sure it is still energy-efficient. Recycling just one aluminium can produces enough energy to power your TV for three hours!


That’s before we get to the energy efficiency of aluminium doors in your home or business. 

Aluminium is a fantastic natural insulator, particularly when combined with airtight seals and triple glazing in our doors. These doors ensure you retain more heat and prevent draughts, reducing energy bills and carbon emissions.

What is the best security door for a house?

The best security door for your home will depend on your specific requirements. The most important thing is that you have a strong material, such as aluminium and a sophisticated lock.

How much does a secure door cost?

The cost of a security door will vary depending on the style, size, materials used and the hardware and security features incorporated. Your choice of glazing (if applicable) will also determine the overall cost.

Are security doors hard to break into?

As the name suggests, a high-security front door is very difficult to break into. This is especially true of an aluminium high-security door. Aluminium is strong and durable, making it difficult to penetrate. The door may also have laminated glass, designed to withstand pressure and an antijacking system to prevent would-be intruders from removing the glass panels to enter. Want to know more?
