How this node works
Where a floor lands on the wall, the inner polystyrene is interrupted to let the slab bear on the concrete core, and the wall steel runs on past so the structure is continuous. Two things must be looked after at that gap: the outer insulation is kept unbroken across the floor edge so no thermal bridge forms, and the interruption on the inside is fire-stopped and re-insulated, since the exposed polystyrene must never be left as a path for fire.
Key points
- ICF wall (core)
- Floor (bearing)
- Continuity of reinforcement
- Fire-protective lining
- Continuous outer insulation
- Form stopped at the floor
