3 Materials

FCR and MCR elements are available in two sizes: semi-sheets and tiles.


Table; Semi sheets

Other shapes and sizes may become available in the near future

Semi-sheets are designed for a higher efficiency in production. The cement requirement per m2 is 40% higher than for tiles. Their dimensions are 60 x 60 cm, 4 pieces per m2 roof are required. Semi-sheets require careful handling and a very even and firm roof structure.

Compared to tiles, the laying of semi-sheets is more efficient.

Tiles

Tiles produced so far have a size of 25 x 50 cm. They are more responsive to slight movements within the roof structure such as bending or distortion due to wind or earthquake. Handling tiles is easy since they weigh is only 2 kg per piece.

Two different shapes are common: the Roman tile and the pantile.


Pantile; Roman tile

Roman tiles have a flat area on which they rest. They fit well, but require a rather even roof structure.

Pantiles have a sinus-like shape and can also fit on slightly uneven roof structures, such as pole timber or bamboo structures.

Per m2 roof 13 pieces are required
