INFORMATION
RESISTANT PROPERTIES
Impervious to water and moisture resistant Cem-Rock™ retains structural stability when wet. In addition it does not feed mildew, rot, mould, and is resistant to termites as it contains zero foodstuff.
FEATURE
Higher resistance to soft body & hard body impact; pull-through and shear loading
DIMENSIONS TOLERANCE (EN 12467:2012)
Level 1 (+/- 3mm)
THERMAL CONDUCTIVITY (EN ISO 10456)
0.39 W/Km
CLASS A1 FIRE RATED PRODUCT
Cem-Rock™ can easily achieve up to 2 hour fire ratings. It releases water vapour during a fire event, helping to cool and contain the fire. No plywood, OSB or drywall panel can claim this.
STRONG AND DURABLE
Stronger than both gypsum boards or fibre cement products and lighter that fibre cement products. Cem-Rock™ safe to work with and extremely user friendly. Easy to cut and score. It is also suitable for curved surfaces as it is pliable (3 meter bending radius). Due to these characteristics Cem-Rock™ increases a building’s life span.

STORAGE
All Cem-Rock® Cement Boards are supplied with a protective plastic sheet wrap. This protection should not be removed until the boards are ready for use. In general, the following steps should be taken to ensure that the boards remain in good condition during storage. All Cem-Rock® Cement Boards should be stored on covered and dry level ground, away from the working area or mechanical plant.
Pallets should be stored safely on firm level ground. If two or more pallets are stacked, the following guidance as well as local legislation and regulations must be observed. The number of pallets per stack is mainly determined by site conditions such as ground conditions, flatness and load capacity of the ground.
LOADING AND UNLOADING BOARDS
Cem-Rock® Cement Boards are supplied on pallets suitable for fork lift unloading by fork lift. If off-loading by crane and slings is envisaged, care should be taken to avoid damaging the edges of the boards. All pallets and crates can be safely handled by using a fork lift or hoisting equipment and straps. Steel cables or chains should not be used as they will damage both the pallet and the boards.
Where crates are removed from a box container, care should be taken not to subject crates and pallets to any impact shock, as this could result in cracking of the boards. Always drive the delivery vehicle as close as possible to where the boards are to be used.
When transporting the boards, it is essential to secure the pallets to prevent sliding. If the boards are subsequently moved around the site, they should be placed on a rigid base suitable for lifting by forklift. Cem- Rock® Cement Boards should always be stored on a rigid base.
