Aluminium windows are some of the most safe and secure options available. However, it's not just the material that makes them resilient; they must be designed with security in mind and manufactured with expert craftsmanship to ensure maximum home security.
At Origin, we understand that windows are not only for aesthetics; they are a critical component of your home's defence. This guide explores how to evaluate your current window’s security features and why high-quality engineering makes all the difference in modern fenestration solutions.

Evaluate your window security using our helpful checklist.
Out of uPVC, aluminium, timber or steel windows, which have the most robust frames?
Look out for security features such as multipoint locks, mechanically crimped frames and hinge guards.
Modern aluminium windows fitted with excellent security features offer a high level of protection.
How Secure Are Your Current Windows?
Evaluating the security of your existing windows often begins with understanding their age and compliance with modern security standards. Since April 1, 2002, building regulations in England have applied to all new windows, covering essential areas such as safety, means of escape, thermal performance and ventilation. An external window is classified as a "controlled fitting", meaning it must meet specific standards to be legally compliant and safe from entry attempts.
If your windows pre-date these regulations or show signs of wear and tear such as being cracked, warped, misaligned or if they frequently jam, rattle or let in draughts, these could be signs that your windows aren't securing properly. Lacking essential security features such as advanced locking systems can compromise integrity.
If any of the following apply, it could be time to seek more secure replacement windows:
- Cracked or rotting frames
- Warped or misaligned frames
- Rusty or weathered hinges or locks
- Rattling or sticking frames
- Draughts or poor insulation
- If the windows are older than 2002
- If the windows on the ground floor and are not fitted with security glass
- External access is possible
- The windows don’t feature strong locks
How Important is Window Material for Security?
The material used for your window frames is a big factor in its overall security and longevity. Aluminium is Origin’s material of choice because of its remarkable strength-to-weight ratio, weighing 67% less than steel while maintaining exceptional durability.
Unlike some materials that can become brittle, rot or warp over time, high-grade aluminium is highly resistant to flexing, warping, weathering and corroding. This structural rigidity ensures that the locking points remain aligned and that the frame cannot be easily bent or forced. Steel is another durable material that supports large panes of glass, but these tend to be heavier and more expensive than aluminium window frames.

Which Are Most Secure: uPVC, Wooden or Aluminium Windows?
While all materials can meet basic security requirements, aluminium offers superior structural rigidity compared to timber frames or uPVC. Aluminium's resistance to warping and corrosion means it maintains a high level of security for decades with minimal maintenance required. Conversely, timber windows may rot, swell, and warp; while uPVC windows can degrade under UV exposure, potentially compromising the strength and alignment of the frames and security systems.
What Makes a Window Secure?
A truly secure window is the result of a well-thought-out design philosophy and priority, where every component works in harmony to maintain operational integrity, performance and tampering resistance. The key elements to look out for include:
- Multi-point locking systems: advanced locking mechanisms engage at multiple points along the frame, making it significantly harder to force open than a traditional single-point lock.
- Hinge guards: these are essential for blocking intruders from "jemmying" the window open from the hinged side.
- Internal beading: glazing should be secured from the inside so that the glass unit cannot be removed from the exterior.
- Robust hardware: handles, hinges and locks must be made from high-quality materials and be capable of withstanding heavy loads and repeated cycles. Origin's stand up to over 50,000 cycles.
How Secure Are Origin Aluminium Windows?
Origin Windows, including the OW70 Slimline and OW80 Premium systems, are engineered to be among the most secure on the market. We combine premium-grade aluminium with precision-engineered components and expert manufacturing all of which is done by us in our Buckinghamshire facility.
Both systems utilise high security locks, which are tested to rigorous standards to ensure your home remains safe from both intruders and the elements. For added protection, hinge guards are installed as standard on all Origin Windows to provide an impenetrable barrier against forced entry. Because we maintain complete control over the sourcing, manufacturing and delivery of every product, we can offer an industry-leading guarantee of up to 20-years on parts, for absolute peace of mind.
Frequently Asked Questions
Is every aluminium window and door secure?
Frequently in the fenestration industry, the fabricator or manufacturer of the product is not the company that actually designs it or who’s brand it is. This means that quality varies significantly between manufacturers, as there is no guarantee that every fabricator adheres to the parent design company’s specifications or quality standards. Origin is unique because we design, engineer, and manufacture all our products in the UK, ensuring consistent excellence.

How do I know if I’m buying secure products?
Look for recognised UK certifications such as the PAS 24 (Enhanced Security), BS EN 6375 Part 1, BS EN 6375 Part 2 (Operational and Strength Characteristics), BS EN 6375 Part 3 (Basic Security) and ISO 9001 (Quality Management).
The most important benchmarks are PAS 24 (Enhanced Security) and Secured by Design (SBD). SBD is a police-backed initiative that recognises products engineered to maximise security and rigorously tested and inspected. Read more about our accreditations.
Which are the most secure windows for businesses?
For commercial settings or large-scale apertures, the OW80 Premium Window is often preferred. It can be manufactured in impressive sizes (up to 7m²) without compromising structural rigidity or security. Our Window and Door systems are PAS 24 certified, making them ideal for high-visibility business storefronts. Security should be a top buying priority, especially if your building is not occupied at night, so selecting windows and doors with a high level of security is a must.
How strong does the glass need to be?
The strength required often depends on the specific security rating desired. For instance, to comply with certain PAS 24 certifications, a BS EN 356 P1A certified glass unit must be installed. Origin Windows can accommodate a range of glazing options, from 28mm double-glazing through to 44mm triple-glazing, allowing your property to benefit from a thermal and secure performance that suits your requirements. Laminated or toughened safety glass is required up to 800m (1.5m around a doorway) on the ground level and within 300mm of a doorway.
How do I ensure my windows are fire-safety compliant?
Building regulations require that windows must provide a means of escape in the event of an emergency. Origin’s top and side-hung windows can be specifically designed to serve as emergency exits. Your local council and local installation partner can guide you through the specific requirements for your property type to ensure full compliance.
What does PAS 24 mean?
PAS or Publicly Available Specification (formerly Product Assessment Specification) is a British Standard for enhanced security performance. It is a standard of testing to measure the resistance of doors and windows to intrusion. In these tests, a window or door is subjected to simulated break-in attempts using various tools and force. Achieving this standard means the product has been independently verified as secure.
