Plinth at sill beam — horizontal GS MW U panel layout, variant I

Junction function

Horizontal GS MW U plinth = variant with the OB-41 angle (specific to horizontal U, not used in S/CH). Vs horizontal S/CH (pp. 29-30):

• OB-41 angle instead of OB-38/OB-42 — the U joint geometry requires a different guide.
• Internal OB-07 instead of OB-06 (horizontal S/CH used OB-06).
• PM1 washers in panel fixing.

Critical installation aspects

• OB-41 angle anchored with expansion anchors to the sill beam; PM1 at each fastener.
• Internal OB-07 — full finishing of the inner edge.
• PURS assembly foam under the panel — eliminates capillary moisture rise.
