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

Junction function

The plinth is the bottom edge of the hall wall — a critical area exposed to rainwater (splash from ground) and capillary moisture (if the sole beam protrudes above grade).

Variant I (projection depth d=20–60 mm) = standard for most industrial buildings:

1. Sole beam (item 03) reinforced concrete or steel with insulation (floor pouring, side thermal insulation).
2. Plinth profile (item 02) steel, supporting the bottom edge of the panel.
3. OB-13 drip flashing (item 05) = plinth flashing with drip edge; projects d=20–60 mm beyond the façade to deflect rainwater.
4. OB-10 drip flashing (item 04) optional band at the bottom edge above the plinth (when the façade projects beyond the beam).
5. OB-08 trim flashing (item 06) on the interior side conceals the panel-to-beam connection.

Critical installation aspects

• OB-13 projection d=20–60 mm — variant I provides a discreet projection (visually minimal), sufficient for typical conditions (without a large upward façade). For taller walls / heavier rainfall, variant II with d=60–100 mm is recommended (page 17).
• OB-13 → OB-10 joint sealed with neutral silicone (item 11) + 4.0×8.0 rivets (item 10) every 200 mm.
• PURS assembly foam (item 08) in a 5–10 mm band between the sole beam and the panel — seals against capillary moisture rise.
• PES tape (item 07) at the panel joint with the plinth profile.
• Plinth drainage — in areas with groundwater, a drainage grate in a 1 m band along the façade; without it, splash water travels under the building after rainfall.

Used in typical wall systems GS MW S and GS MW CH.
