Abstract
A method for producing a frame as a window or door frame that is made from hollow-profile elements and that has a chamber that contains an insulating foam core, wherein the frame is assembled from several hollow-profile elements. In order to insulate such a frame in an economical way, the insulating foam core is generated first after joining the frame through filling the chambers that are provided in the hollow-profile elements and that communicate with each other with foam.
Claims20
A method for producing a door or window frame (1) made from hollow-profile elements (2, 3, 4, 5) with at least one chamber (7) that contains an insulating foam core (22), comprising:
- assembling the frame (1) from several serially connected hollow-profile elements (2, 3, 4, 5) by first connecting the hollow-profile elements (2, 3, 4, 5) to form the frame (1) and then,
- inserting insulating foam (22) in fluid form into the at least one chamber (7) through at least one opening (8) in the frame, and
- allowing air to escape from the chamber (7) through the at least one opening (8) and/or at least one additional opening (10, 11, 12) in the frame.
