Abstract: A device adapted to deliver an insulation enhancing polyurethane foam within profiles used in doors, windows and related applications comprising an insulating material supply member (1) extending into a polyurethane forming and discharge member (2) adapted to enter and move linearly along a chamber (25, 35) of a thermally insulated sash or frame profile assembly and deliver therein a polyurethane foam that absolutely abuts onto the walls of the chamber without exerting undesirable stresses thereupon. The insulating material supply member (1) comprises independent pipes (8, 9) delivering a polyol constituent (A) and an isocyanate constituent (B) that are mixed together with a supply of air within a mixing compartment (4) of the polyurethane forming and discharge member (2) to produce the desired insulating material.
