Abstract
A spacer profile (50) for a spacer profile frame mountable in the edge area of an insulating window unit for forming an intervening space (53) between window panes (51, 52), has a profile body (10) made of synthetic material and comprises one or more chambers (20) for accommodating hygroscopic material. A metal film (30) encloses the profile body on three-sides such that, in the bent/assembled state of the spacer profile, the non-enclosed inner side of the profile body is directed towards the intervening space between the window panes. The not-enclosed inner side of the profile body comprises openings (15) for moisture exchange between hygroscopic material accommodated in the chamber(s) and the intervening space between the window panes. The metal film comprises a profile (31a-g, 32a-g) on each end directed towards the intervening space of the window panes. Each profile has at least one edge or bend.
