Are uPVC Doors A Good Choice for Your Home?

When it comes to home security, choosing the right doors is of paramount importance. One popular option is UPVC doors. UPVC (Unplasticised Polyvinyl Chloride) doors are known for their durability, energy efficiency, and low maintenance requirements. However, some concerns about their security features and effectiveness in safeguarding homes have been raised. Are these concerns founded or are uPVC doors still a good choice for your home?

Construction and Material Strength

UPVC doors are constructed using a rigid, plastic-based material with excellent strength and durability. The frames are reinforced with galvanized steel, making them resistant to forced entry attempts. Unlike traditional wooden doors, uPVC doors do not splinter or crack easily, making them more challenging to break through.

Multi-Point Locking Systems

One of the critical security features of uPVC doors is the incorporation of multi-point locking systems. These systems engage multiple locking points along the door frame, typically at three or more positions. This design enhances security by distributing the force of any attempted break-in across several points, making it significantly harder for intruders to bypass the lock.

Anti-Snap Cylinder Locks

UPVC doors can be equipped with anti-snap cylinder locks, which offer added protection against lock snapping — a common technique used by burglars. Anti-snap cylinders are designed with sacrificial sections that break away if excessive force is applied, rendering the lock ineffective. This feature ensures that even if an intruder tries to snap the lock, they will not gain access to the property.

Security Glass Options

UPVC doors can be fitted with laminated or toughened glass for enhanced security. Laminated glass consists of multiple layers with a polymer interlayer, making it resistant to shattering. Toughened glass is chemically treated to increase its strength and durability. Both options provide an additional barrier against break-ins and ensure that even if the glass is compromised, it will not give way easily.

Internal Beading

UPVC doors often feature internal beading, where the glass is fitted from the inside, preventing it from being removed externally. This design choice prevents potential intruders from removing the glazing and gaining entry.

UPVC Door Common Repairs

There are several common issues that can cause problems with uPVC doors. The door can slip so that it is no longer level with the frame, or an old gearbox will need to be replaced. The good news is a professional locksmith will be able to diagnose and usually fix these problems quickly and have the uPVC door working as good as new.



UPVC doors offer a range of security features that make them a reliable choice for homeowners. With their robust construction, multi-point locking systems, anti-snap cylinder locks and options for reinforced glass, uPVC doors provide a strong deterrent against break-ins. However, it is essential to ensure that UPVC doors are sourced from reputable manufacturers and installed by qualified professionals. In addition, regular maintenance and upkeep of the door’s components, particularly the locking parts by a reputable locksmith is also crucial. Ultimately, when combined with other security measures, the evidence suggests uPVC doors can contribute significantly to creating a secure home environment.
