Hello all,
In my house I need to have firedoors. The two floors of the building have carpets and under the door metallic stripe. ( I don't know if the carpets have the related BS standards.)
Based on firedoor's manufacture's manual the gap under the door should me maximum 10mm from the floor.
As I can see on the manufacture's manual with the tests of the door they do not have any reference for carpets.
Should I consider the carpet as floor or the metallic strip? or the unfinished floor?
Any Idea what is appropriate and/or minimum requirement?
thank you
