Interior Doors   (Main Site)

    Jambs for fire doors are available as rated or non-rated interior and rated or non-rated exterior. Building codes vary in different cities and counties so check with your building inspection department to verify what type of jamb will be required. 
    Our most commonly used jamb for our 20 minute fire doors in residential construction would be our "FrameSaver" primed pine exterior non-rated jamb. The inside edge of this jamb is left natural so you can stain it to match your door. The garage side of the jamb is primed and ready for paint.
    Fire doors for residential construction are primarily used between the house and attached garage. An exterior jamb is recommended for this application. This will be a rabbetted jamb and will include weatherstripping and a threshold that will keep the cold air, bugs and rodents  from entering the house from the garage. Once again check with your building department to determine if a non-rated jamb is sufficient.
