Solidor vs Rockdoor — how do they compare?

Both are respected UK composite-door names, but they are built in noticeably different ways, which shapes their feel and appeal.

Solidor and Rockdoor compared

The table sets out the main differences between the two brands, based on their published construction descriptions. Both make quality composite doors, both offer security-certified options and both are fitted through local installers rather than sold direct. The differences are in core construction, skin material and the resulting feel and style, rather than one being clearly better than the other.

Solidor builds around a solid timber core with a GRP outer skin, aiming for the heavy, rigid feel of a traditional timber door with low maintenance. Rockdoor uses a multi-layered construction with an ABS outer skin and internal reinforcement, designed for impact resistance and a particular focus on security.

Indicative comparison; confirm current specifications with the installer.

Construction and feel

The biggest difference is what is inside the door. Solidor's solid timber core gives the door real weight and rigidity, producing the substantial feel many people associate with a quality traditional door, finished with a GRP skin that resists weather and needs no painting.

Rockdoor takes a layered approach, combining an ABS outer skin with an inner reinforced structure. ABS is valued for impact resistance, so the skin resists denting and knocks well, and the reinforcement contributes to the brand's security positioning. The result is a door that feels tough and solid in a slightly different way to a timber-core door, with its own characteristic look.

Security, style and colour

Both brands offer doors meeting recognised UK security standards, and both have Secured by Design certified options. Rockdoor is often highlighted for its security-focused construction and reinforcement, while Solidor doors paired with quality multipoint locks and anti-snap cylinders are also strongly secure. As always, the specific door set and its cylinder determine the real security level, so confirm the certification and insist on an anti-snap 3-star cylinder.

On appearance, Solidor is known for an extensive range of colours and styles, giving plenty of scope to match a property. Rockdoor offers its own distinctive range with a slightly different finish characteristic owing to the ABS skin. Viewing finished sample doors from both brands in person is the best way to judge grain, colour depth and overall look.

Price and which to choose

Pricing for both brands overlaps and depends heavily on size, glazing, hardware and the installer, so neither is reliably cheaper than the other. Quote-to-quote comparisons matter more than brand-level generalisations, and the security specification, glazing and guarantee should be matched when comparing.

Choose Solidor if you want the heavy, rigid feel of a solid timber core, a traditional look and a very wide choice of colours and styles. Choose Rockdoor if its reinforced, impact-resistant construction and security focus appeal, and you like its range and finish. Both are sound, well-regarded choices, so the decision often comes down to the look and feel you prefer in person and the installer you trust to fit it.
