PAS 24 Security Explained for Aluminium Windows & Doors

When choosing new aluminium doors or windows, most people think about style, energy efficiency and how much natural light they will bring into the home.

But security is just as important.

One term you may come across when comparing aluminium windows and doors is PAS 24. It is often mentioned in product specifications, building regulation guidance and security-rated glazing systems.

In simple terms, PAS 24 is a security standard that shows a window or door has been tested to resist common methods of forced entry.

For homeowners, architects, builders and developers, understanding PAS 24 can help you choose aluminium doors and windows that not only look good, but also provide tested protection.

What Is PAS 24?

PAS 24 is a UK security standard for doorsets and windows.

It sets out enhanced security performance requirements for products that are intended to resist attacks commonly associated with casual or opportunistic burglars. BSI describes PAS 24 as covering test methods and acceptance criteria for doorsets and windows intended to offer a level of security suitable for dwellings and similar buildings.

The standard applies to different materials, including aluminium, PVCu, timber and composite systems.

For aluminium windows and doors, PAS 24 helps demonstrate that the product has been designed and tested with security in mind.

What Does PAS 24 Test?

PAS 24 testing is designed to assess how well a window or door can resist attempted break-ins.

Rather than simply looking at one component, the test considers the complete product.

That can include:

The frame
The glazing
The locks
The hinges
The handles
The fixings
The overall strength of the system

For doors, PAS 24 usually refers to the complete doorset, not just the door leaf. This means the frame, hardware and locking system are all important.

For windows, it looks at how the window performs as a complete unit.

Why PAS 24 Matters

PAS 24 matters because a window or door is often one of the most vulnerable points in a property.

A strong-looking aluminium door is not automatically secure. The locks, glazing, frame design and installation all need to work together.

PAS 24 gives you reassurance that the product has been tested against recognised security requirements.

1. It Helps Protect Against Forced Entry

PAS 24 is designed to reflect the type of attack associated with opportunistic burglary. Secured by Design explains that the test is intended to mimic attack methods using tools that are easy to conceal.

This makes the standard especially relevant for homes, extensions, new builds and ground-floor glazing.

2. It Gives You a Clear Security Benchmark

Without a recognised standard, it can be difficult to compare the security of different aluminium doors and windows.

PAS 24 gives homeowners and specifiers a clearer way to understand whether a product has been tested to a recognised level.

3. It Supports Building Regulation Requirements

In England, Approved Document Q provides guidance on security in dwellings. It applies to new dwellings and covers reasonable standards for doors and windows to resist unauthorised access.

This is one reason PAS 24 is often discussed on new-build projects and residential developments.

4. It Can Support Secured by Design Requirements

PAS 24 is also closely linked with Secured by Design, the official police security initiative. Secured by Design provides guidance on security standards for doors, windows and glazing products.

While PAS 24 and Secured by Design are not exactly the same thing, they are often connected in security-focused specifications.

PAS 24 and Aluminium Doors

Aluminium doors are popular because they are strong, slim and modern. They are often used for large openings, garden access and contemporary home designs.

PAS 24 can apply to a range of aluminium door systems, including:

Aluminium entrance doors
Aluminium sliding doors
Aluminium bifold doors
Aluminium French doors
Aluminium patio doors
Glazed aluminium doors

For large glazed openings, security is especially important. A wide sliding or bifold door can transform a living space, but it should also provide confidence that the opening is properly protected.

A PAS 24-tested aluminium door system will usually combine strong frames, secure locking points, suitable glazing and tested hardware.

PAS 24 and Aluminium Windows

PAS 24 can also apply to aluminium windows.

This is particularly important for windows that are easy to access, such as:

Ground-floor windows
Basement windows
Windows near flat roofs
Windows beside doors
Windows in extensions
Windows in new-build homes

Aluminium windows can offer excellent strength and slim sightlines, but security still depends on the full system.

A PAS 24-tested aluminium window will usually include secure locking, suitable glazing, robust frame design and tested resistance against forced entry.

Does PAS 24 Mean a Product Is Burglar-Proof?

No product can be described as completely burglar-proof.

PAS 24 does not mean a window or door can never be broken into. Instead, it means the product has been tested to resist a recognised level of attack.

The aim is to make forced entry harder, slower and less attractive to an opportunistic intruder.

In many cases, burglars look for quick and easy access. A secure, tested aluminium window or door can help reduce that risk.

What Is the Current PAS 24 Standard?

The PAS 24 standard has been updated over time.

The current version commonly referenced is PAS 24:2022+A1:2024, which relates to enhanced security performance requirements for doorsets and windows in the UK. NBS lists PAS 24:2022+A1:2024 as current and notes that it includes test methods, classification, marking, design, installation and acceptance criteria.

When comparing products, it is worth checking which version of PAS 24 is being referenced and whether the certification applies to the exact product configuration you are buying.

PAS 24 vs Approved Document Q

PAS 24 and Approved Document Q are connected, but they are not the same thing.

PAS 24

PAS 24 is a product security standard. It focuses on the tested performance of doorsets and windows.

Approved Document Q

Approved Document Q is building regulation guidance for security in dwellings in England. It explains security requirements for certain new residential buildings.

In simple terms:

PAS 24 relates to the tested product.
Approved Document Q relates to building regulation guidance.

If you are working on a new-build project, your architect, builder, installer or building control provider can help confirm what is required.

PAS 24 vs Secured by Design

PAS 24 is a test standard for windows and doors.

Secured by Design is a wider police-backed security initiative covering products, design principles and crime prevention. Secured by Design references recognised standards for doors, windows and glazing, including PAS 24.

A product may be PAS 24 tested, Secured by Design accredited, or both, depending on the manufacturer and specification.

What Makes an Aluminium Door or Window Secure?

PAS 24 performance depends on more than one feature.

A secure aluminium system may include:

Multi-Point Locking

Multi-point locking helps secure the door or window at several points around the frame.

Strong Aluminium Frames

Aluminium is naturally strong, making it a popular choice for secure, slim-framed systems.

Secure Handles and Hardware

Locks, handles, hinges and cylinders all play an important role in security.

Suitable Glazing

The glass specification matters, especially for doors and accessible windows. Laminated glass is often used where enhanced security is required.

Tested System Design

PAS 24 is about the complete tested system, not just individual parts.

Professional Installation

Even a high-quality product needs to be installed correctly. Poor installation can weaken security, create gaps or affect performance.

Is PAS 24 Only Needed for New Builds?

PAS 24 is often discussed in relation to new-build homes because of Approved Document Q.

However, it can also be a useful standard for renovations, extensions and replacement projects.

Even where PAS 24 is not strictly required, many homeowners still choose security-rated aluminium windows and doors for extra peace of mind.

This can be especially valuable for:

Ground-floor extensions
Large rear sliding doors
Bifold doors opening onto gardens
Accessible side doors
Homes in exposed or secluded locations
Properties with large areas of glazing

Should You Ask for PAS 24 Certification?

Yes, if security is important to your project, it is sensible to ask whether the product is PAS 24 tested.

You can ask:

Is the product PAS 24 tested?

Check whether the system has been tested to PAS 24.

Which version of PAS 24 applies?

Standards are updated, so ask which version is referenced.

Does the certification apply to my exact product?

Performance can vary depending on size, style, glazing and hardware.

Is the glass specification included?

Security-rated glazing may be required for certain applications.

Is the installation included in the security specification?

Correct fitting is essential for the product to perform as intended.

Does PAS 24 Affect the Look of Aluminium Doors and Windows?

Not necessarily.

Modern aluminium systems can combine slim frames, large glass areas and strong security performance.

This means you can still achieve a clean, contemporary look while choosing products that are tested for security.

For many homeowners, aluminium is attractive because it offers a strong balance of:

Slim sightlines
Strength
Durability
Modern design
Thermal performance
Security options

Is PAS 24 Worth It?

For many projects, yes.

PAS 24 gives you a recognised way to compare security performance. It can support building regulation requirements, improve peace of mind and help protect your home against opportunistic forced entry.

It is especially worth considering for accessible windows and doors, large glazed openings and new-build homes.
