The Ultimate Guide to Window and Door Security: What to Look For

When choosing new windows and doors, most homeowners focus on style and energy efficiency — but security is just as important. The right products can significantly improve your home’s protection, giving you peace of mind as well as comfort.

Multi-Point Locking Systems

One of the biggest upgrades in modern windows and doors is multi-point locking — securing the frame at several points simultaneously for far greater resistance to forced entry.

Benefits

  • Increased resistance to forced entry
  • Better sealing for improved energy efficiency
  • Even pressure across the frame for added strength

Things to Consider

  • Slightly higher cost than basic locking systems
  • Requires proper installation to work effectively

Lock Ratings and Standards

Not all locks are created equal. Certified options meet recognised standards and are tested against real-world break-in methods.

Benefits

  • Meets recognised standards such as BS 3621
  • Anti-snap, anti-drill, and anti-pick protection
  • Tested against real-world break-in methods

Things to Consider

  • Higher security locks may increase overall cost
  • Older doors may need upgrading to support them

PAS 24 Certification

PAS 24 is the key UK benchmark for window and door security — independently tested, recognised by building regulations, and trusted by insurers.

Benefits

  • Independently tested against common burglary methods
  • Recognised by building regulations and insurers
  • Provides confidence in product performance

Things to Consider

  • Not all products meet PAS 24 as standard
  • May limit some lower-cost options

Glass Specifications

Modern glazing plays a major role in overall security. Toughened and laminated glass significantly increases the effort required to break through.

Benefits

  • Toughened glass for added strength
  • Laminated glass that holds together when broken
  • Double or triple glazing for multiple layers of protection

Things to Consider

  • Laminated and triple glazing can increase cost
  • Heavier glass may require stronger frames

Frame Strength and Materials

The frame supports the entire system. Reinforced uPVC resists bending, warping, and forced entry — essential for any high-performance locking system to do its job.

Benefits

  • Reinforced uPVC improves rigidity
  • Resists bending, warping, and forced entry
  • Supports high-performance locking systems

Things to Consider

  • Higher quality frames may come at a premium
  • Poor-quality frames can weaken overall security

Professional Installation

Even the best products need to be installed correctly to perform. Accurate fitting, secure fixing, and compliance with building regulations are all non-negotiable.

Benefits

  • Accurate fitting and alignment
  • Secure fixing to your property
  • Compliance with building regulations

Things to Consider

  • Cutting corners on installation can compromise security
  • Always choose a trusted, experienced installer

Additional Security Features

Extra features such as restrictors, internal beading, and security hinges can further strengthen your home’s protection.

Benefits

  • Restrictors to control window opening
  • Internal beading to prevent glass removal
  • Security hinges and reinforced hardware

Things to Consider

  • Optional extras may increase overall cost
  • Not all features are necessary for every home
