What Is PAS 24 & Secured by Design — And Why Should Homeowners Care?
When choosing new windows and doors, most homeowners focus on appearance, energy efficiency, and price — but security is just as important.
That’s where PAS 24 and Secured by Design come in! This is also a requirement for Building Regulations Document Q for new builds and extensions.
With our ADVANCE 70 windows and doors, security is built into the system. This helps homeowners create properties that are stylish, thermally efficient, and designed to provide enhanced protection and peace of mind.
Modern homeowners are increasingly searching for PAS 24 / Secured by Design windows and doors – home improvement products that combine security, thermal efficiency, and modern styling. The ADVANCE 70 System is designed to meet these requirements while offering long-lasting performance and elegant design options for every property style.
What Is PAS 24?
PAS 24 is a recognised UK security standard that tests how well windows and doors resist attempted break-ins.
Unlike basic security checks, PAS 24 tests the complete window or door system, including:
- Frames
- Glazing
- Hinges
- Hardware
- Locks
Products are rigorously tested against common burglary methods including:
- Forced entry
- Lock manipulation
- Mechanical attacks
- Impact testing
This ensures the entire system performs as a high-security solution rather than relying on just one component.
For homeowners, PAS 24 compliant windows and doors provide greater confidence that their property is protected against modern intrusion methods.
What Is Secured by Design?
Secured by Design (SBD) is the official police-backed initiative focused on improving home security and reducing crime.
In simple terms:
- PAS 24 is the security testing standard
- Secured by Design is the wider accreditation scheme
Together, they represent one of the highest standards of residential security available for modern windows and doors in the UK.
Secured by Design products are specifically designed to help reduce opportunities for criminal activity while maintaining attractive aesthetics and everyday practicality.
Why PAS 24 & Document Q Matter for Modern Homes
Modern burglars often target weak locks, outdated hardware, and poorly secured window systems.
PAS 24 certified windows and doors are designed and tested to resist these common attack methods while also helping properties meet modern building regulations, including Document Q.
Benefits of PAS 24 and Document Q compliant windows and doors include:
- Better protection against break-ins
- Enhanced peace of mind
- Improved home security
- Potential insurance benefits
- Compliance with modern building regulations
- Stylish designs without compromising safety
For homeowners, this means choosing products that not only look beautiful but also deliver modern security and long-term performance.

Choosing Between PVC Patio Doors and PVC French Doors: A Homeowner’s Guide
When you’re planning to upgrade the rear of your home — whether it’s opening up to the garden, bringing in more light, or improving thermal efficiency — the choice between PVC patio doors and PVC French doors is a big one. Both options have their strengths, and making the right decision depends on how you want your space to look, feel, and function. In this guide, we’ll break down what each type offers so you can choose with confidence.
🏡 What Are PVC Patio Doors?
PVC patio doors — like the MASTERslide system from Selecta Systems — are horizontal sliding doors. They glide smoothly on tracks and are designed to give you a wide, unobstructed view of the outdoors.
✨ Why homeowners love them:
- Large, uninterrupted glass panels maximise natural light.
- Slim sightlines create a modern look and bring your garden into focus.
- They’re available in 2, 3, or 4 pane layouts — ideal for wider openings.
- Smooth sliding action makes them easy to operate even with children or heavy loads.
- A low threshold version can make transitioning outside easier and more accessible.
- Multiple configurations and colour options (including modern and traditional shades and wood-effect foils) let you compliment your home.
👷♂️ Performance highlights:
- Excellent thermal performance keeps heat in and cold out — especially with double or triple glazing.
- Enhanced security options meet rigorous PAS 24 and Secured by Design standards.
📊 Best for: Modern homes, wide openings, and anyone who loves a panoramic view and light-filled rooms.
🚪 What Are PVC French Doors?
French doors are a pair of hinged doors that meet in the middle and open outwards or inwards. The ADVANCE 70 French doors from Selecta marry classical style with modern performance.
🌿 Why they’re a favourite:
- Their timeless design suits both traditional and contemporary homes.
- They create a graceful transition between your living space and garden.
- You can open one or both doors, improving ventilation on warm days.
- Lots of style and finish options (including coloured or wood-effect foils) let you match your home’s personality.
🛡 Performance highlights:
- French doors from Selecta are multi-chambered for thermal efficiency, helping keep energy bills down.
- PAS 24 & Secured by Design options give peace of mind on security.
- Choose from double or triple glazing to suit your energy and acoustic performance goals.
📊 Best for: Homeowners who want classic elegance, flexibility in use, and a door that feels like an architectural feature.
⚖️ Patio vs French: How to Choose
Here’s how to think about the two in everyday terms:
📍 Space and Layout
- Patio doors slide, so you don’t need extra clearance — perfect if you’re tight on outdoor space.
- French doors swing open, which can feel more dramatic but may require more room.
🌞 Light and Views
- Patio doors usually provide larger uninterrupted glass areas, maximising light and views.
- French doors still let in lots of light — and because both doors can open, you get a more open feel.
🎨 Style and Aesthetics
- Choose patio doors for a sleek, modern look.
- Go for French doors if you love a classic, elegant entrance that enhances outdoor living.
🔐 Security and Performance
Both options from Selecta Systems can be manufactured with high-security locks, multi-chambered frames for thermal efficiency, and excellent weather performance. Whichever you pick, you won’t have to compromise on comfort or safety.
🧠 Final Thoughts
There’s no universal “best” — just what’s best for your home and lifestyle.
- If your priority is light, view, and modern simplicity, PVC patio doors could be the right fit.
- If you value traditional charm and flexible ventilation, PVC French doors might win your heart.
Whichever you choose, high-quality PVC options like those from Selecta Systems deliver on security, thermal performance, and aesthetics — all key for a comfortable, enjoyable home.
