1. A spacer profile for use as part of a spacer profile frame, which is suitable for being mounted in and/or along an edge area of an insulating glazing unit for forming and maintaining an intervening space between glazing panes, wherein the spacer profile extends in a longitudinal direction (z) and comprises in a cross section (x-y) perpendicular to the longitudinal direction (z), a first width (b1) in a transverse direction (x), which is perpendicular to the longitudinal direction (z), and comprises a first height (h1) in a height direction (y), which is perpendicular to the longitudinal direction (z) and to the transverse direction (x), and comprises an inner side in the height direction (y), which is arranged to face towards the intervening space in the assembled state of the spacer profile frame, and an outer side, which is arranged to face away from the inner side, the spacer profile comprising:
a profile body formed from a first heat insulating material and having, as viewed in the cross section (x-y) perpendicular to the longitudinal direction (z), outer side walls extending in the height direction and being separated by a distance (b2) in the transverse direction smaller than the first width (b1), the outer side walls defining a longitudinal groove which is open to the inner side and each side wall having an inner protrusion protruding towards the opposite side wall into the groove, and
a diffusion barrier film made from a second material and firmly bonded with the profile body and, as viewed in the cross section (x-y) perpendicular to the longitudinal direction (z), continuously extending: (i) in the transverse direction (x) over the profile body on the outer side of the spacer profile, (ii) continuing in the height direction (y): (a) on the outside of the side walls and/or (b) in the side walls to a second height (hp), and (iii) extending into the protrusions.
