Corner · GS MW

External corner 90° — vertical GS MW U panel layout (variant I)

Premium right-angle corner with concealed fixing. GS MW U panels terminate at the corner column, with mineral wool between panels and column. OB-02/OB-03 flashings + PM1 washer — same logic as S/CH (p. 21), differing aesthetically through the absence of visible fasteners.

Junction function

90° GS MW U corner = premium version of the S/CH corner (p. 19). Key difference: fasteners concealed within panel joints + mandatory PM1 at the corner.

Structural principles are identical — see 90° S/CH corner.

Critical installation aspects

  • PM1 at the corner is fixed through the panel joint into the corner column; on each of the two corner walls separately.
  • OB-03 + OB-02 identical as in S/CH, but without visible fasteners — clean aesthetics.
  • Mineral wool in the column-adjacent cavity — critical for thermal bridge control.
  • Wind edge zone — fastener densification within the 3 m perimeter strip.
