We are a supply and fit installation contractor, not the manufacturer. Information here is reproduced from manufacturers' literature for reference only; always confirm it directly with the manufacturer before specifying, ordering or installing.
Siniat's standard single-frame C stud partitions, EN 1364-1 tested and EN 13501-2 classified, from 30 to 120 minutes with a wide choice of boards. Max height is Siniat's EN fire-state height (the figure Siniat say to use unless otherwise specified); the cold-state (mechanical, L/240 at 200Pa) height is shown alongside. Use the filter to narrow by performance or board.
