Any-angle corner — horizontal GS MW S/CH panel layout

Junction function

Corner at an angle ≠ 90° in horizontal layout = non-standard building geometry. Similarly to the vertical layout (p. 20), it requires a specially ordered angled OB-03 flashing.

Typical applications:

• Halls with irregular plan (adapting to the plot).
• Office annexes within halls (e.g. hall frontage at 135°).
• Halls with a curved façade broken down into trapezoidal segments.

Critical installation aspects

• Special order for OB-03 — the production angle must be accurately measured on site from the building shell; steel structure tolerance ±2° vs. design.
• Greater flashing width for acute angles (<90°) — typically 400-500 mm.
• Wind edge zone extended to 4 m for acute angles (increased suction).
• Mineral wool pushed into the corner with greater tolerance (max 20% compression).
• Check with the structural engineer — an acute angle increases wind suction loads in the corner; additional fasteners in the edge zone may be required.
