Plinth at sole plate beam — horizontal GS MW S/CH panel layout, variant I

Junction function

Plinth in horizontal panel layout = bottom row of panels laid horizontally. Vs the vertical layout (p. 16-19):

• OB-38 Z-profile instead of C-profile — guide rail for the bottom edge of the horizontal panel (the panel “rests” on the Z-profile like on a shelf).
• OB-14 drip flashing = plinth trim specific to the horizontal layout (geometrically different from OB-13 used in the vertical layout).
• OB-06 corner flashing at the bottom — finishing of the interior side of the plinth.

Variant I = projection d=60–100 mm — analogous to variant II of the vertical layout (the horizontal arrangement is “by default” wider in projection).

Critical installation aspects

• OB-38 Z-profile anchored with expansion anchors (item 10) to the sole plate beam + 4.0×8.0 rivets to the panel (item 12); anchor spacing every 60 cm.
• Mineral wool (item 08) in the space between the panel and the beam — eliminates the thermal bridge.
• OB-14 drip flashing projects 60-100 mm beyond the façade with a 30 mm drip edge; seal joints with neutral silicone.
• OB-06 internal corner flashing at the bottom — conceals the junction of the horizontal panel with the interior floor.
• Ground slope away from the building — minimum 2% within a 1 m strip to drain rainwater.
