Suffolk White Prefinished 35mm Fire Door

The Suffolk White Prefinished 35mm Fire Door delivers the charm of classic rural design with the practicality today’s properties demand. Featuring a clean white finish over a finely grooved MDF Prime+ surface, this model brings crisp lines and familiar cottage styling into any interior scheme. Whether used in a characterful HMO conversion or a modern B&B setup, it blends contemporary design with reliable performance.

Designed exclusively by Climadoor, this door conceals a high-performance MGO sandwich core beneath its durable face. That internal strength gives it FD30 fire resistance while keeping the thickness to a modest 35mm, ideal for settings where standard 44mm fire doors can’t be accommodated. As a result, it’s a smart choice for projects working within legacy frameworks or more compact structural openings.

This version comes prefinished in crisp white, ready to install as-is or paint in your preferred shade. It’s an elegant and versatile solution for those who refuse to compromise on safety or style.

A Different Take on Fire Safety

Standard fire doors often come in at 44mm thick, but this Suffolk model is specifically crafted at 35mm. That slimmer build makes it perfectly suited for homes with narrower linings, without sacrificing protection. This door delivers FD30 fire resistance for up to 30 minutes, offering vital reassurance in shared homes, rentals, or anywhere extra security is key.
