How this node works
The metal cassette has its edges folded back and hooks onto a clip on the vertical rail: the fixing is concealed, and one panel can be unhooked and replaced on its own. Between cassettes an open joint stays deliberately unsealed — it drains and equalises the pressure, while the insulation and the cavity sit behind.
