Internal Fire Doors
Discover the OTIF UK FD30 Fire Door
The OTIF UK FD30 Fire Door combines stunning modern aesthetics with excellent safety performance.
Featuring the slimmest slightlines available on the UK market for an internal fire-rated door, it ensures you can maintain a consistent, sleek design throughout your property, even where fire-rated doors are required.
The OTIF UK FD30 Fire Door has been tested to British and European standards (BS EN 1634-1: 2014). It can achieve fire integrity and radiation resistance classes E30 to E120, as well as smoke protection class Sa.
Using the European Standard Fire Test Classification, the ‘E’ refers to the integrity of the door and how long, in minutes, it can stop flames and hot gases from transferring from one side to another.
All single and double-leaf door configurations within OTIF’s Internal Fire Door range, with optional sidelights and toplights, have been tested to this standard.
