Fire rated doors are built and tested to withstand the heat, smoke, and flames of a roaring fire while also providing a means of escape. However, the fire door alone does not offer fire protection – it is the fire door assembly (fire door, frame, hardware, glass, etc.) that when used together offers fire protection. If one component of the opening is not listed for use as part of the fire door assembly, the entire assembly is void of its fire-resistance rating.
