How high-security composite doors help trade partners meet PAS 24 standards

December 4, 2025

When it comes to composite front doors, one door doesn’t fit all. What it absolutely must do, however, is keep a home secure from potential intruders for peace of mind.
With recent ONS data showing a noticeable increase in UK burglary reports across 2023 and 2024, security is now a primary consideration for homeowners and developers alike. Installers offering proven high-security composite doors are better positioned to respond to this demand.
Meeting strict performance benchmarks is vital and with PAS 24 now a standard requirement across new-builds and many replacement projects, trade partners need high-security composite doors that offer proven resistance, reliable performance and straightforward compliance.
At Dekko Window Systems, we supply a complete composite door range designed to help installers meet PAS 24 with confidence. Whether you’re working on a new development, a private extension or a local authority retrofit, our Infinity, Comp Door and Solidor ranges give you the flexibility and security specification required to win more work.
In this guide, we look at how Dekko’s composite doors support PAS 24 compliance and why choosing the right supplier makes the process simpler for every project.

Why is PAS 24 compliance essential for today’s installations?

PAS 24:2016 is the recognised security standard for doorsets in the UK. It sets out the testing procedures a door must pass to demonstrate resistance to forced entry using the tools and methods most often associated with opportunistic break-ins.

For installers, PAS 24 compliance matters because it:

• Supports Part Q requirements for new-build homes
• Helps meet local authority and housing association specifications
• Reduces the risk of callbacks and compliance disputes
• Demonstrates that the product has passed rigorous, third-party testing
• Offers customers confidence in the long-term security of their property

What makes a door truly secure?

Security is rarely about a single feature. A PAS 24-ready door must bring together multiple performance factors, including a solid core and robust construction for superior strength, an impact-resistant outer skin, reinforced frames, advanced locking systems, high security hardware and tested glazing and bead systems – and these are all benefits of composite doors.
Dekko’s composite door portfolio is built around these principles, giving installers a reliable, trade-focused solution designed for real-world performance.

Where do high-security composite doors fit within today’s market?

The composite exterior door market continues to grow, driven by demand for better insulation, long-lasting materials and market-leading security. For installers, the challenge is that one door type can’t satisfy every project.
That’s why Dekko offers three distinct composite door systems that provide superior protection. Each provides its own combination of performance, design flexibility and specification options, helping you respond to different budgets and requirements without compromising compliance.

Our ranges include:
Infinity – Seamless timber-look finish, foam-filled core and Kubu-ready as standard
Comp Door – Timber core design with CoolSkin technology and autofire lock
Solidor – Premium 48mm solid timber core for outstanding strength and security
With three clear options, installers can match the right product to the right property and offer the perfect composite door, all backed by our supply reliability and trade support.

How do high-security composite doors help you meet PAS 24?

PAS 24 focuses on one key question: can the door withstand sustained attempts at forced entry?
Dekko’s wide range of composite doors are specified with features that support security at every stage, from construction to hardware to installation. Here’s how each range contributes to PAS 24 compliance.

Infinity

Infinity is designed for installers who want the look of timber with the benefits of advanced manufacturing. Its seamless finish and Deceuninck outerframes offer both style and substance, but security remains at the core of the system. Key PAS 24-driven features of Infinity include:

• Robust foam-filled slab engineered for impact resistance
• Rigid Deceuninck outerframe supporting structural stability
• High quality hinges and hardware
• Multi point locking for secure engagement
• Fully Kubu-ready – offering real-time smart security monitoring

Infinity doors are ideal for installers working on modern new-builds or domestic replacements where customers want contemporary style with reliable security performance.

Comp Door

Comp Door is designed for innovation-led performance. The next-generation timber core gives installers the reassurance of natural rigidity, while modern materials and technology ensure durability and stability over the long term. Why Comp Door supports PAS 24 compliance:

• Solid timber core engineered for high impact resistance
• CoolSkin technology for outstanding heat stability and long-term structural performance
• Autofire lock included as standard for secure operation every time the door closes
• Kubu smart hardware integration
• Durable skins resistant to splitting and cracking

For installers handling demanding specifications or environmentally exposed properties, Comp Door provides consistent performance from day one.

Solidor

With its 48mm solid timber core, Solidor is widely recognised as one of the strongest composite doors on the UK market. Its structural stability and density make it an excellent choice for projects where security takes top priority. Solidor’s PAS 24-focused strengths include:

• 48mm timber core delivering exceptional strength
• Reinforced frames offering superior mechanical stability
• High security multi locking points
• Extensive hardware options from leading brands

For homeowners and developers seeking best-in-class security, Solidor remains a trusted and well-established choice.

The rise of smart security in composite doors

Frequently Asked Questions

Are high-security composite doors essential for meeting modern regulations?

Yes. For most new-build properties, PAS 24 is non-negotiable. With more homeowners and developers demanding security-led features, trade installers can no longer rely on a single composite door range or a one-size-fits-all approach. Dekko’s Infinity, Comp Door and Solidor ranges ensure you always have the right composite door option available for complete customer satisfaction.

Which composite door is best for high security applications?

All three of Dekko’s composite door ranges offer high levels of security, but Solidor’s 48mm solid timber core provides exceptional strength for projects where maximum resistance is required. Comp Door and Infinity also deliver strong security performance, making them suitable for a wide variety of PAS 24-aligned specifications.

Can installers order PAS 24-ready composite doors for fast delivery?

Yes. Dekko offers fast UK-wide delivery and a simple ordering process for all its modern composite doors. Installers near the M4 can also collect from our trade counter.
