Glam Rock in the 70's was mostly bands or artists such as:
David Bowie
Sweet
Slade
New York Dolls
T-Rex
Iggy Pop
Roxy Music
Marc Bolin
and numerous others.
Kiss was a rock band, or even a hard rock band that had a theatrical image and stage show that ~could~ be considered glam, but the music itself wasn't even the least bit glam (well, until the disco-ish era).
So to answer the question, it would depend on if you are talking about their look or their sound. In the 80's, KISS could have been grouped into the Glam Metal era of 80's rock, but still, not really what is considered "Glam Rock" which was mostly a 70's era genre.
hope that helps
