<p>Insulated composite aluminum profile, a method and a device for manufacturing thereof. The composite profile comprises two separate profile portions provided with grooves. Plastic strips engage the grooves in order to interconnect the profile portions and form an enclosed space for an insulating plastic foam. The profile portions are placed in a fixture, which determines the dimensions of the composite profile and the plastic foam is inserted in the space in order to expand and cure therein. Thence, the profile is removed from the fixture and eventually rolled as to the outer rims of the grooves, which are deformed and thereby fix the plastic strip.</p> |
