The EDILCENTRO ceramic tiles can be mounted in every side of roof with a length that ranges from 9 to 10 meter, in case the length is larger it is advised to insert e second tube for the collection of waters. For the placement of the Portuguese brick it is required to have a minimum inclination of 30%. If the inclination is more than 50%, in areas with heavy wind, the elements can be fixed by nails or steal threads. A regular placement of the tiles can be achieved by mounting the roofs over an appropriate supporter. It can be over a wooden supporter of 4x4 m fixed in parallel with the line of the roof's arc, separating it every 3-4 meter for a few centimeters to adjust the air flow. The axis between the supporters should be appropriate for the kind of tile that is used and these are verified in the factory before its usage and mounting. The first supporter, close to the arc, should be at least 2cm higher than the others in order to guarantee a correct inclination of the first row of the tiles which has no other row underneath. The first row of the tiles should be 7-8 cm away from the water collector.
