- Openings and services set out from the model
How a wall panel works
Vertical loads flow down the studs to the bottom track and the slab; lateral loads from wind and earthquakes are carried by braced panels – diagonal steel straps or structural sheathing – into hold-downs and anchors. Openings are framed with jamb studs and a lintel.

Envelope
Fire, acoustic and thermal performance come from the tested lining and insulation system around the frame – we detail the walls to the board and insulation manufacturers' tested systems.
