New A1 Product – ProcellaPro

ProcellaPro is a non-combustible A1 fire rated, calcium silicate-based fibre cement board using cellulose fibres for structural strength. ProcellaPro is used as a building board or sheathing board for many applications where a non-combustible solution is required

The board is pre-squared to large format sheet size of 2500 x 1250mm as standard on the production line.

ProcellaPro achieves A1 rating to BS EN 13501-1 (with a PCS value of 0.85MJ/kg) making this suitable for any project over 18m, unlike some cement particle boards which contain wood chip.

ProcellaPro is available in 12mm thickness, as standard, giving your walls additional rigidity and strength and excellent sound damping.


ProcellaPro is less absorbent than plasterboard, timber or sheathing board containing timber fibres (such as some cement particle board). The calcium silicate and cement base used in the production process makes the board highly resistant to insect and fungal attacks.
