Window — insPIRe® S sandwich panel (horizontal layout)

Junction function

Window in a sandwich panel wall with horizontal panel layout — panels arranged horizontally (horizontal module axis). Unlike the vertical layout, the panels continue above and below the window — interrupted only along the band corresponding to the window opening height.

This is a simpler geometry than the vertical layout:

• Panels above the window (item 01 upper) continue uninterrupted, with their bottom edge meeting the window frame.
• Panels below the window (item 01 lower) continue uninterrupted, with their top edge meeting the external sill.
• Side panels are interrupted around the window opening — they require OB-01 + OB-02 on the window frame.

Critical installation aspects

• Panel division at the opening — horizontal panels should not be cut; the edges of the window frame determine the panel module height (e.g. a 1.2 × 1.5 m window requires a 1.5 m high panel module along the opening band).
• OB-37 window sill (item 07) — in the horizontal layout the sill rests directly on the lower panel. Slope of 5% towards the exterior, 30 mm drip edge.
• Top edge of the opening — OB-01 corner flashing conceals the joint between the upper panel and the frame; PES sealing tape (item 08) on the interface with the panel.
• Side edges of the window — analogous to the vertical layout: window frame + OB-01/OB-02 + foam + silicone.
• Edge zone of the opening — double fastener density within a 30 cm band from the window edge.

Vertical vs horizontal layout

Aspect	Vertical layout	Horizontal layout (this one)
Number of cut panels	all 4 sides of the opening	only 2 sides (left + right)
Ease of window installation	lower	higher
Façade aesthetics	linear vertical pattern	linear horizontal pattern
Maximum panel length	16 m	16 m (but the module height width counts)
Price per opening	baseline	-15% (fewer cut edges)

Horizontal layout preferred for:

• buildings with large window bands (shops, car showrooms — strip windows)
• halls with windows at the top (daylighting of warehouse halls)

Used in the insPIRe® S hall wall system.
