<p>The frame has a casing (1) comprising two parts with pairs of complementary sections (1a, 1b) assembled such that relative positions of the parts are modifiable. The sections are fixed to each other by connection units e.g. bolts (26) and nuts (27). Axles of the connection units are perpendicular to nested flanges (8, 12) and parallel to glazings (2) made of transparent insulating material. Nesting depth of the flanges from the sections of each pair is determined during assembly of the frame based on thickness of the glazings. Synthetic strips (13a, 13b) are inserted in nesting of the flanges.</p> |
