ABSTRACT The method of making a deformable sealant strip having a continuous strip of rigid corrugated material embedded longitudinally within mastic material wherein a continuous linear-rigid spacer is first corrugated and then fed in this condition into an extruder cross head wherein such rigid corrugated spacer is encompassed by a mastic. The strip is coiled for subsequent use in retrofitting double pane windows as well as making dual insulated windows. The extruder that receives the rigid corrugated spacer in its crosshead provides a mastic that surrounds and encompasses the spacer without deforming it.
