How to Choose the Right External Door Supplier
Maintenance and Longevity of External Doors

Beyond aesthetics and thermal efficiency, its primary function is to deter intruders and protect occupants.

Therefore, understanding the security features offered by suppliers like Grpcompositedoors.com, and what to look for, is paramount.

Modern external doors integrate advanced technology and robust construction to provide peace of mind.

Key Security Features to Look For

High-security external doors incorporate multiple elements that work in conjunction to resist forced entry.

• Multi-Point Locking Systems:
  • Mechanism: These systems engage multiple bolts (typically 3 to 5) into the door frame at various points (top, middle, bottom) when the handle is lifted or the key is turned. This secures the door along its entire height, making it much harder to prise open than a single-point lock.
  • Benefit: Spreads the load of any attempted forced entry across multiple points, significantly increasing resistance.
  • Data Point: Many modern composite and UPVC doors, including those from Grpcompositedoors.com, come standard with multi-point locking systems.
• High-Security Cylinders (Kitemarked, Anti-Snap, Anti-Drill, Anti-Pick):
  • Cylinder Type: The cylinder (where the key is inserted) is a common target for burglars.
  • Kitemark: Indicates the cylinder meets British Standards (BS 3621, TS 007) for security and durability.
  • Anti-Snap: Prevents “lock snapping,” a common method where the cylinder is broken to gain entry.
  • Anti-Drill: Hardened steel pins or plates resist drilling.
  • Anti-Pick: Complex internal pin configurations make picking difficult.
  • Example: Grpcompositedoors.com specifically mentions “high security Yale and Ultion kitemarked cylinders,” which are well-regarded brands known for these features.
• Reinforced Door Frames:
  • Construction: The frame surrounding the door must be as strong as the door itself. Look for reinforced steel or robust UPVC/composite frames that resist splitting or flexing under pressure.
  • Fixings: Ensure the frame is securely fixed into the wall structure with long, strong screws or anchors.
• PAS24 Certification:
  • Standard: PAS24 is a publicly available specification in the UK that sets standards for enhanced security performance for doors and windows. Products that achieve this certification have undergone rigorous testing to resist common forced entry techniques.
  • Significance: If a door is PAS24 certified, it means it has been independently verified to offer a high level of security. Grpcompositedoors.com explicitly states their locks are “PAS24 certified.”
• Secured by Design Accreditation:
  • Police Preferred Specification: This is a UK police initiative that promotes crime prevention through good design. Products with SBD accreditation have been tested to a higher standard than basic security requirements.
  • Benefit: Provides an extra layer of assurance for homeowners regarding the security of their door.
• Strong Door Material and Construction:
  • Composite Doors: Their multi-layer construction (often with a solid timber or foam core and a robust GRP skin) makes them incredibly strong and impact-resistant.
  • Steel-Reinforced UPVC: UPVC doors with internal steel reinforcement offer significantly better security than non-reinforced versions.
  • Solid Timber Core: A solid core inherently provides greater resistance to impact compared to hollow or semi-solid doors.
• Hinge Security:
  • Dog Bolts/Security Hinge Bolts: These are fixed bolts that engage into the frame when the door is closed, preventing the door from being removed even if the hinges are attacked or removed.
  • Anti-jemmy strips: These are profiles designed to prevent a crowbar from being inserted between the door and the frame.

The Role of Professional Installation

Even the most secure door can be compromised by poor installation.

• Correct Fit: The door must be precisely fitted into the opening, with no gaps or excessive play that could be exploited.
• Secure Fixing: The frame must be securely anchored to the structural opening according to manufacturer guidelines.
• Proper Alignment: Misaligned doors or frames can affect the proper engagement of locking mechanisms, reducing their effectiveness.

While Grpcompositedoors.com offers “supply only” doors, ensuring professional and competent installation is crucial for maximizing the inherent security features of their products.

Homeowners opting for DIY installation should ensure they follow manufacturer instructions meticulously or hire a qualified tradesperson.

By prioritizing doors with these features and ensuring proper installation, homeowners can significantly enhance the security of their property, making it a much less attractive target for potential intruders. Maintenance and Longevity of External Doors
