FIELD: construction.
SUBSTANCE: group of inventions relates to an installation and a method for making foamed polyurethane for insulation inside profiles used in doors, windows and other similar structures, as well as to thermally insulated units of profiles. Plant comprises device (1) for supply of insulating material, from which extends device (2) for forming and discharging polyurethane, made for inserting inside cavity (25, 35) of heat-insulated assembly of leaf or frame profiles and straight movement in this cavity to provide therein foamed polyurethane, which tightly adjoins walls of cavity without creation of undesirable pressure on these walls. Insulating material supply device (1) comprises separate tubes (8, 9), supplying polyol component (A) and component (B) containing isocyanate, which are mixed together with supplied air inside mixing chamber (4) of device (2) for forming and discharging polyurethane to obtain the required insulating material. Polyurethane feed assembly starts feeding a profile assembly at one end, having length in accordance with the industry standard, and moves back to fill the cavity with polyurethane insulating material. Method of making foamed polyurethane for insulation involves a step for feeding foamed polyurethane material with components (A) and (B) inside the cavity. Thermal insulated assemblies of profiles are obtained.
EFFECT: technical result achieved by using a group of inventions is to provide optimized thermal insulation of profiles used in frame structures intended for insertion into various types of articles.
