surface has anti adhesive properties to the polymer material of the profile spacer 8 thin films of polyester or polyethylene have proven themselves useful for this purpose if a moisture setting system is used as polymer material for profiled spacer 8 films 33 34 must exhibit a sufficient water vapor permeability so the moisture necessary for the setting process can diffuse through the films optionally films 33 34 may exhibit a specific porosity or a microperforation films 33 34 confer on lip portion 10 an additional rigidity during the setting process and a thin layer between two films 33 34 and sets into a flash or tab 41 projecting beyond edge 40 of lip portion 10 after the setting of the polymer is finished this flash or tab 41 is cut along edge 40 of the lip portion 10 together with films 33 and 34 and is removed this results in a clean final edge of lip portion 10 being achieved even in the transition zone of profile spacer 8 remaining film pieces 33 34 are then removed from profile spacer 8 and lip portion 10 fig3 illustrates another embodiment of a spacer 146 in the lower part of a window opening here the spacer 146 is placed along the lower edge of glazing 1 and serves as a.
