Prepare a foam structure that includes hollow coalesced foam strands and, optionally, solid coalesced foam strands using an extrusion die block equipped with apertures that promote forming the hollow strands and, optionally, the solid foam strands.

Hollow strandfoam and preparation thereof

Polyolefin foam useful for sound and thermal insulation

An insulating polymer foam sheet having two major sides and at least one groove in at least one of said sides. At least a portion of the foam sheet adjacent to the groove is compressible and resilient, and has a length and height the same as the adjacent groove. Each groove and compressible portion is of a width that permits the groove to receive and tightly fit around a support member in a frame building construction.
