Installation must comply with the technical standards applicable in each territory Code of
practice for design and fixing of roofs with clay roofing tiles and Tejas Borja specifications.

FITTING

Roof tiles on the roof surface must be fixed to the support to a greater or lesser extent, depending on the pitch. In the case of

singular points such as eave lines, edges, hip lines, valleys, joints and the ridge line, all roof tiles and accessories of these joints
must be fixed to the battens.

We recommend that all roof tiles that form the perimeter of each skirt be fixed mechanically.

VENTILATION

Under-tile ventilation is necessary at all times. This will
guarantee the durability of the material used to build

There must be a continuous air flow between eave lines

the roof tiles and the support. As a result, eave lines, 5
