Siniat encasement systems are all based on 12.5mm and 15mm Siniat Fireboard. Siniat Fireboard is defined as Type F to BS EN 520 and it is Siniats opinion that Fireboard can be switched with Megadeco or Universal boards to achieve the same fire protection as these are both Type F also.

Should it be desired to used Universal or Megadeco instead of Fireboard the project design team will need to review this and maybe seek approval from a fire engineer to cover the variation from the tested system.
