Yes, Kodak makes HSI (High Speed Infrared) in 4x5 inch sizes.  This film
must be loaded in total darkness (as must all sheet film).  It is very
sensitive to fingerprints, and so try to use lintless cotton gloves (or
equivalent) when loading, or make very sure to only handle the film by
the edges.  The bellows of your camera need to be IR safe.  Some are
not. Test before committing expensive film and valuable time.  The film
is extremely sensitive to fogging when taking out/ replacing the
darkslide.  I keep the holder cover with the darkcloth when the holder
is in the camera, even when taking out/replacing the dark slide.  Keep
the film cool.
