FIELD: construction.
SUBSTANCE: spacing shape for use in a spacing frame (50) of an insulating glass unit with a hollow body (10) of a shape from plastic material with a chamber (20), which stretches in the longitudinal direction (Z), which has an inner wall (12), an outer wall (14), the first side wall (16) and the second side wall (18), which are connected to the inner wall (12) and the outer wall (14) to form the chamber (20), with the first and second reinforcing layers (22, 24) from metal material, which stretch along the first and second side walls (18) and partially on the outer wall (14) with the first distance (a1) from each other and have the first and second thickness (d2), with a diffusion-barrier layer (26), which is formed directly on the outer wall (14) between reinforcing layers (22, 24) and is connected to them in diffusion-impermeable manner to create the diffusion barrier (27).
EFFECT: increased operational reliability.
