Sourced from the East Coast of North America, American Walnut is ‘dark hardwood’ that offers a unique and distinctive colour. Our American Black Walnut FD30 Fire doors are a deep chocolate brown, with subtle purple and creamy tones within its presence. The Veneers we use adds character with its natural curvy and crown cut appearance. Our American Walnut doors are available in a wide range of styles and finishes that can be adapted to suit any interior. Our fire-rated doors are made from high performance three-layer wood particleboard conforming to BS EN 312-2 Certification.

Please note, all veneers are natural products and some variation should be expected, although, matching veneers are available. Please contact us for further information. Images used for illustrative purposes only.

The American Walnut FD30 Fire Door is manufactured using high-quality FSC approved materials. The core is constructed from a robust, graduated density particle board providing the doors formation and strength. Solid core doors are denser, heavier and have excellent insulation and sound-reducing qualities. They can be used for a wide range of applications including fire and acoustic specifications.

Door Lippings

The door core is lipped with a range of hardwood lippings, that are contrasting or sympathetic to the door face finish. Lippings can be supplied either exposed or concealed, providing aesthetic variations to conform to your chosen décor.

Fire Performance

Our FD30 Fire Doors provide 30-minute fire resistance.

Fire specifications can be easily recognised from their IFC tamper-evident label and BM TRADA fire door plug system. Our FD30 Fire doors are made with fire-resistant timber controlled by ISO approved standards.

Acoustic Performance

Our FD30 Fire Doors also offer acoustic performance and with a wide range of core variations we can achieve up to 45Db acoustic rating with the correct sealing specification, ask a member of the team how or explore our seals web sector.

Door Frame

The frame can be constructed from MDF, softwood for on-site finishing or a choice of hardwoods for a stained or lacquered finish.

Other Applications

The American Walnut FD30 Fire Door can be applicated for use with most aluminium partitioning systems, where the door frame wall thickness is greater than 2mm that requires an aesthetically pleasing visual solution.

Finishing Options

As with all our doors, customisation can be made to meet project requirements. Doors can be cut and re-lipped to different sizes on request to give greater flexibility and still maintain their durability and fire rating.

We would recommend that all special sizes are made to order through our bespoke service.

Pairs are available as a best match from stock but we would advise having these made bespoke for better visual match satisfaction, as all veneers are bespoke.

Glazing Options

Glazing Apertures can be introduced to provide an aesthetically pleasing and functional solution for safety and visibility.
