Why Window Security Matters
Windows do more than let in light and fresh air, they are a critical part of your home’s security system. At Colin’s Sash Windows, we design and install double glazed windows that combine with firm glass options, reinforced frames, and high-performance locking systems to resist intrusion, protect your belongings, and give you peace of mind.
What Makes Our Double
Glazed Windows Secure?
1. Strong, Impact-Resistant Glass
All our double glazed units are designed for strength and security:
- Toughened Glass – Resistant to shattering under force.
- Laminated Glass – Holds together even when cracked, preventing easy entry.
Benefit: Strong glass plus reinforced frames make forced entry more difficult and time-consuming, deterring burglars.
2. High-Performance Locking Systems
Our double glazed windows feature advanced locking solutions that secure your home::
- Multi-point locking systems secure the window at several points along the frame.
- Key-locking handles to prevent unauthorised manipulation.
- Mid-rail locking and travel restrictors for vertical sliding sash windows.
- Anti-jemmy hinges to resist prying.
Benefit: Locks work with the frame and glass to maximise security, making windows hard to open without proper access.
3. Reinforced Frames and Multi-Chambered Profiles
- uPVC frames are reinforced to resist bending or forced leverage.
- Internal beading secures the glass from inside, stopping intruders from removing panes. Some frames have to be externally beaded by design but they’re high security.
- Multi-chambered profiles increase rigidity and energy efficiency.
Benefit: Reinforced frames + secure glazing + advanced locks → complete window security system.
4. Brand-Approved Accreditations and Standards
We ensure every installation meets UK security and quality standards:
- PAS 24 – Rigorous testing against forced entry methods.
- Secured by Design® – Police-backed certification for high-security windows.
- Document Q – UK Building Regulation compliance.
- FENSA, TrustMark, and CERTASS membership – Guaranteeing professional installation and quality.
- Glass and Glazing Federation (GGF) – – Industry-standard best practices.
Benefit: Independent verification and certified installation provide trust, insurance compliance, and peace of mind.
5. Installation Integrity
Even the best security features fail if installed incorrectly. At Colin’s:
- Locks are fully aligned and engaged.
- Frames are square, fixed, and reinforced.
- Seals and glazing are properly installed.
Benefit: Professional installation ensures all security features perform as designed, protecting your home from day one.
Security Across Different Window Styles
| Window Type | Security Level | Key Features |
|---|---|---|
| Casement Windows | High | Locks along the frame distribute force evenly, making it difficult to pry open. |
| Tilt & Turn Windows | Very High | Multi-directional locking mechanism adds extra resistance against forced entry. |
| Sliding Sash Windows | High | Includes mid-rail locks and travel restrictors for traditional style with modern security. |
| Vertical Sliding Windows | Medium-High | Requires reinforced rollers and secure locks. Our sash windows exceed standard security. |
Note: Our sash windows include mid-rail locks and travel restrictors to maintain traditional sliding functionality while improving security.
