Our explainer: what a Shield™ panel is, how a building goes from drawing to finished shell, and what the envelope does for energy, air and sound.
What the video covers
-
A Shield panel is a cold-formed steel skeleton embedded in a core of expanded polystyrene (EPS): strength and insulation in one panel.
