Wall junction — horizontal GS MW S/CH panel layout

Junction function

Wall junction in horizontal layout = analogous structure to the vertical one (p. 21). Geometric difference:

• Panels terminate at the wall — in horizontal layout panels are longer, so the wall may feature multiple rows of panels, each meeting the masonry.
• OB-19 + OB-07 flashings continued along the full height of the wall.

All other principles are identical — mineral wool in the gap, masonry waterproofing, verification of geometric deviations in the shell stage.

Critical installation aspects

• Multi-row panels meeting the masonry — each row requires independent OB-19 fixing to the wall and to the panel.
• Masonry waterproofing must be continued behind every panel row; without it the strip is left unprotected against water.
• Mineral wool fills the gap between panels and masonry along the full height; class A1 for fire-resistant walls.
• Thermal movement of masonry ≠ panels — compensation gap of 5–10 mm to be maintained.
