<p>The profile (1,2) contains several compartments, with a reinforcement profile (5,6) in at least one reinforcement chamber (1c,2c). The reinforcement profile consists of two spaced-apart parallel inner or outer metal plates (5b;6a,b) joined by at least one non-metallic intermediate piece (5c,6c). The intermediate cavity between the inner and outer plates is at least partly filled with non-metallic insulating material (7,8) in the form of one or more flexible foam plastic bar-shaped moldings.</p> |
