A filler material for use as spacing elements used with insulated glass includes a flexible air and water tight, tube in which a powdered absorption material is placed. The filler material is shaped to have filled tube sections of the absorption material and empty tube sections located in series and separated from each other by flat seams. This arrangement reduces the amount of absorption material and allows convenient cutting of the strip without loss of absorption material.
