OTIF Unlatched Internal Fire Door

OTIF is proud to present the Unlatched Internal Fire Door—a pioneering system that unites uncompromising safety with refined design. Featuring the slimmest sightlines of any internal fire-rated system on the UK market, it allows light and elegance to flow seamlessly through interiors without compromising on performance.

Independently tested to rigorous British and European standards (BS EN 1634-1:2014), the system delivers outstanding protection, achieving fire integrity and radiation resistance from E30 up to E120, alongside smoke control to class Sa.

The tested range encompasses all standard single- and double-leaf configurations, with optional sidelights and toplights, offering architects and designers complete flexibility in creating safe, sophisticated spaces.
