Product Information

Where character-led design meets modern safety requirements, the Suffolk White Prefinished 35mm Fire Door stands out with understated confidence. Bringing together timeless cottage appeal and vital fire protection, this Climadoor-exclusive model offers a rare combination: an elegant, lightweight fire door that works with older or narrower frames.

FSC Certification

Featuring a flush grooved MGO sandwich board core, this fire-rated option doesn’t compromise on strength. The face is crafted from Grooved MDF Prime+, offering a sleek white finish that’s ready to hang immediately. It’s equally easy to topcoat should you wish to personalise your colour palette. It offers the kind of flexibility that suits a variety of interiors, whether you're working on a character home, converting a multi-let property, or refreshing a compact space that can’t accommodate a 44mm door.

Each size has been designed with proportional style in mind. The 686mm and 762mm versions carry a five-panel layout, while the wider 838mm door shifts to a balanced six-panel formation, giving you consistency throughout the home without sacrificing detail. This makes it easy to retain the Suffolk look across various room sizes and configurations.

A smart choice for HMOs, boutique guesthouses or anywhere you need subtle safety built into a slim-profile frame, this fire door delivers quiet confidence. Fully certified, it must be installed to match the accompanying fire door documentation for safe and legal performance. It’s also FSC® (INT-COC-003944.500) certified, ensuring that the materials used have been responsibly sourced.

Matching products are available across the Suffolk collection, including oak veneered alternatives and glazed versions, along with standard non-fire-rated models in 35mm and 40mm thicknesses.

Sizing

Available in the most commonly required imperial widths:

  • 686mm & 762mm – 5-panel layout

  • 838mm – 6-panel layout

Each fire-rated door is supplied at 35mm thickness and specifically designed for scenarios where traditional fire doors cannot be used.

Sustainability

This product is made using FSC® (INT-COC-003944.500) mix certified materials, ensuring every door supports well-managed forestry and ethical manufacturing processes. The engineered MDF Prime+ face and MGO core balance reduced waste with a high level of fire resistance and strength.

A Consistent Look Throughout

The Suffolk collection offers flexibility across all internal door needs. From glazed styles that introduce natural light to oak prefinished versions for a warmer look, there are matching options to suit every room. Whether you're upgrading one space or transforming an entire property, consistency is easily achievable with this comprehensive range.

Questions about Suffolk White Prefinished 35mm Fire Door

Can I paint over the prefinished white surface?

Yes, although it’s ready to hang as supplied, the Prime+ MDF face is also suitable for top-coating in your preferred colour if you want to customise the finish.

What makes this fire door suitable for older frames?

Its 35mm thickness fits where standard 44mm fire doors often can't. This makes it ideal for refurbishment projects where original door linings are being retained - provided that they comply with the door's fire certificate.

Is the Suffolk design available with glass?

Yes. The wider Suffolk range includes glazed variants that match the same panel layout and groove detailing, allowing natural light to flow through interior spaces.
