Are composite doors more secure than uPVC?

Yes - the 44mm timber core resists cutting far better than uPVC's hollow multi-chamber profile, and composite doors are usually specified with better locks by default.

Are composite doors more secure than solid timber?

Yes for like-for-like spec - timber can be split with a well-placed kick, GRP-skinned composite absorbs impact and springs back.

Security Concerns

How Secure Are Composite Doors?

Composite doors are the UK's most secure front door format - here's exactly why, from PAS24 testing to 3-star cylinders and multi-point locks.

Overview

A modern composite door combines a 44mm timber-core slab, a GRP outer skin that resists cutting and impact, a multi-point locking mechanism engaging 5-7 points down the door edge, and a 3-star anti-snap cylinder. Independently tested to PAS24:2022, they're specified by police-approved Secured by Design schemes and required by many new-build warranties.
