The Koto FD120 Fire Door is manufactured using high-quality FSC approved materials. The door is constructed using Warm Springs Core with a composite mineral fibre board applied to all edges.

Door Lippings

The door core is lipped with a Maple stained lipping, that is 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 FD120 Fire Doors provide 120-minute fire resistance.

Fire specifications can be easily recognised from their IFC tamper-evident label and BM TRADA fire door plug system. Our FD120 Fire doors are made with fire-resistant timber controlled by ISO approved standards.

Acoustic Performance

This core is not well suited to high acoustic requirements.

Door Frame

The frame is constructed from a hardwood timber with a choice of a stained or lacquered finish.

Other Applications 
This Door type must be purchased as a complete Door set.

The Koto FD120 Fire Door is made to order, which can be offered in a variety of door sizes and finishes.

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.
