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.
Freestanding Siniat I stud wall linings, boarded on one side and clear of the existing wall, at 600mm or 400mm stud centres (400mm shown in brackets in the reference). Fire ratings are EN classified, from the boarded side only. Max height is the EN fire-state height for fire-rated systems and the cold-state height (L/240) where no fire rating is claimed. Use the filter to narrow by performance or board.
