Parapet — roof end — sandwich panel D

Junction function

Roof end at parapet is the “second end” of the building — a 3D corner analogous to the start, but on the opposite side of the structure. The roof ridge zone meets the upper part of the parapet here.

Difference from the roof start: here the parapet is crowned with a standard OB-35 flashing (variant II, higher profile) instead of a custom one — because the geometry is repeatable in the catalogue.

Critical installation aspects

• OB-35 vs OB-34 — OB-35 has a higher external profile (better parapet coverage) and is preferred for tall buildings (>10 m) where wind can drive rainwater inward.
• OB-29 covering roof flashing — contacts the trapezoidal corrugation of the roof panel; PES sealing tape is required.
• 5% slope of the OB-35 flashing towards the roof — water drains to the gutter, not down the wall elevation.
• PU foam (item 08) fills the interior of the 3D corner, ensuring thermal continuity.
• Double-density fasteners in the roof edge zone (1.5 m from the parapet) — PN-EN 1991-1-4 requirements for wind loads.
• OB-02 corner flashing — closes the 90° angle between the roof plane and the wall; may be omitted in low buildings where aesthetics are less important.

Used in the pitched roof insPIRe® D multi-span system.
