Abstract (en)
[origin: WO9961503A1] Process for making evacuated insulation panels comprising the steps of a) making a block of (semi-)rigid open celled polyurethane or urethane-modified polyisocyanurate foam via a slabstock process, b) cutting said foam block into foam panels, c) enveloping at least one of said panels in a gastight vessel, d) evacuating the whole to an internal pressure of about 5 mbar or less, and e) hermetically sealing the whole, wherein the cutting of the foam block into foam panels is done parallel to the rise direction of the foam.
