The present invention relates to a heat insulation and support structure between a moving window (sliding window) and a fixed window constituting a sliding window system, or between a moving window and another moving window. More particularly, the present invention relates to a window chassis insulating structure and a glass panel supporting (mounting) structure including technical improvements in a center bar portion in which a window chassis of a movable window and a fixed window (or other movable window) overlap each other when a sliding window of a two-side supporting frame window having a two-sided supporting frame for supporting only both sides of a glass window constituting a sliding window system, is closed.

The present invention relates to a process for producing composite profiles comprising at least two metal shells which are joined by struts comprising a thermoplastic material and a core comprising rigid polyurethane foam, which comprises introduction of the starting components of the rigid polyurethane foam into a hollow space formed by the metal shells, with the rigid polyurethane foam being formed, and subsequent application of a surface coating to the outer surface of the composite profile by means of a powder coating or baking enamel, where the rigid polyurethane foam is obtained by reaction of the following components: A) at least one polyisocyanate, B) at least one polyfunctional compound which is reactive toward isocyanates, C) one or more blowing agents comprising at least formic acid, D) optionally one or more flame retardants, E) optionally one or more catalysts and F) optionally further auxiliaries or additives,
wherein the starting components of the rigid polyurethane foam do not comprise any inorganic fillers.

A thermally enhanced extrudate includes a channel, a first wall, and a second wall. The channel extends along a longitudinal axis from a first end to a second end of the thermally enhanced extrudate and is shaped to receive glass or a frame. The second wall is spaced from the first wall. The first wall and the second wall partially enclose a thermal break extending along the longitudinal axis. The thermal break has a first width defined between the first wall and the second wall at an upper end of the thermal break and a second width defined between the first wall and the second wall at a lower end of the thermal break. The thermally enhanced extrudate further includes a solid insulation material in the thermal break between the first and second walls and formed by curing a flowable material.
