Finished in clean white and featuring Climadoor’s signature vertical-groove design, this exclusive fire door is a smart choice for traditional homes, HMOs, B&Bs or anywhere a full 44mm fire door just won’t squeeze in.

This FD30-rated door delivers up to 30 minutes of certified fire resistance, all wrapped up in a 35mm thick construction. The flush grooved MGO core ensures solid performance, while the white Prime+ finish means it's ready to hang straight away or top-coat it in a colour of your choice for a truly tailored finish.

A perfect fit for light, airy interiors, the Suffolk 35mm Fire Door offers both form and function. The vertical grooves lend a familiar, understated look suited to both modern and period properties, while the robust core and fire-rated glazing ensure essential protection where it counts.

Whether you’re upgrading a rental property or fitting out your family home, this versatile fire door works seamlessly across your space. Pair it with matching standard Suffolk doors or opt for the oak finish alternative to tie in warmer tones.

Please note the slight design variations based on width:

• 5-panel design applies to widths: 686mm & 762mm
• 6-panel design applies to width: 838mm
