Timber Window Security: Specifying for High-Net-Worth Clients

• 24 June 2025|
• News

Any architect working on luxury residential projects knows that security must be a top priority when specifying windows.

Clients investing millions in premium properties expect security systems that work without compromising the overall style of the window. Timber windows, particularly sought-after because of their elegance and beauty, must also incorporate security hardware, robust frames and strong glazing to be suitable for high-end projects.

The good news is that timber windows, when sourced from a quality supplier, can provide excellent security, creating spaces that look beautiful but are also protected from intruders.

At Lomax + Wood, we have a range of beautiful, secure timber windows that add luxury aesthetics and peace of mind to any project.

Security in luxury properties

High-value properties present attractive targets for intruders, making comprehensive security measures non-negotiable. Beyond the obvious financial implications, architects working with clients understand that peace of mind is paramount.

Today’s luxury developments require fenestration solutions that combine traditional craftsmanship with advanced security technology, creating barriers that deter break-in attempts whilst maintaining the aesthetics of the design.

What contributes towards timber window security?

Modern timber window security extends far beyond basic key locks and window restrictors. Contemporary specifications must address multiple security layers, from reinforced frame construction to advanced glazing systems and precision-engineered hardware. This multi-faceted approach ensures that every component contributes to timber window security.

Timber windows security must comprise of several different elements which all work together to provide protection against intruders.

Strong timber frame construction

The foundation of effective timber window security lies in robust frame construction. At Lomax + Wood, our frames utilise engineered timber construction techniques that create a durable, strong window frame.

Our flush casement windows and sash window designs incorporate multiple security features at the manufacturing stage, creating inherently strong structures that resist forced entry attempts.

Unlike inferior timber windows that may weaken over time, our engineered approach ensures frames remain secure throughout their operational life. Our hardwood options, including engineered Oak, provide exceptional strength-to-weight ratios. The dense grain structure of these premium timbers creates natural resistance to impact damage, whilst the engineered construction process eliminates weak points that intruders typically exploit.

Protection through robust glazing

Glazing in luxury applications delivers benefits that exceed just thermal efficiency.

Our glazing specifications can be customised to meet specific security certifications, ensuring compliance with insurance requirements and building standards.

The internal glazing system design featured in our range of windows means that glazing units cannot be removed from the exterior, creating an additional security layer that forces potential intruders to confront multiple barriers.

Our timber windows can also include laminated glass units which incorporate multiple layers of glass with interlayer materials that hold fragments together even when broken, creating a web-like barrier that continues to resist penetration.

Secure hardware options

Hardware is perhaps the most important element of timber window security.

Our extensive ironmongery range includes multi-point locking systems that secure windows at multiple points around the frame perimeter. These systems distribute locking forces across the entire frame.

Our casement windows feature sophisticated espagnolette locking systems with multiple shoot bolts that engage into keeps embedded within the frame. Precision engineering ensures smooth operation whilst maintaining exceptional security performance.

Our PAS 24 (2016) certification guarantees that these systems meet the most demanding security standards required for insurance and regulatory compliance.

For sash window applications, we specify advanced locking mechanisms that secure both sashes without compromising the traditional look of the window.

These systems incorporate concealed locking points that maintain authentic appearance whilst providing modern security performance. The integration of window restrictors allows controlled ventilation whilst maintaining security integrity.

Our hardware specifications include tamper-resistant fixings that prevent removal or manipulation from the exterior. Every component is tested to ensure consistent performance under extreme conditions, providing the reliability that luxury developments require.

Comprehensive security certification

Professional specifications demand verifiable security performance.

Our timber window security systems achieve PAS 24 (2016) certification, the industry standard for security performance. This certification requires extensive testing of complete window assemblies, including frame construction, glazing systems, and hardware.

The testing process evaluates resistance to various attack methods, including forced entry attempts, tool attacks, and sustained assault scenarios. Achieving this certification demonstrates that our systems provide genuine protection against determined intrusion attempts, giving architects confidence when specifying for high-value projects.

Part Q compliance also ensures that our security solutions meet Building Regulations requirements for residential developments. This regulatory compliance simplifies the specification process whilst guaranteeing that security performance meets statutory standards.

Lomax + Wood: bespoke timber windows

Beyond security performance, our timber windows deliver the aesthetic and functional benefits that luxury projects demand.

Sustainability is key to our ethos: whether working with Redwood, Oak, or Accoya, all of our timbers are sustainably sourced. We are proud of the fact that every piece of timber used in our made-to-order timber windows is FSC® or PEFC certified. Unlike other sustainability credentials, our full Chain of Custody certification guarantees complete traceability throughout the supply chain, ensuring that our timber comes from forests that are sustainably managed.

All of our windows are made-to-order and fully customisable. The extensive range of finishes available allows architects to specify timber windows that complement any architectural style. From contemporary developments requiring sleek profiles to heritage projects demanding traditional detailing, our made-to-order approach ensures the perfect solution for virtually any project.
