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

the roof with their optimal characteristics, improving the
hygrothermal performance of the roof tiles against the ROWS

moisture resulting from condensation.

There must be a continuous air flow between eave lines 7

and ridge line. To this end, a space must be left between 6

the roof tiles and the support. As a result, eave lines,
ridge lines and singular points must never be filled in with 5

Ventilation roof tiles will also be installed in a uniform
manner across the surface of the roof. In case of dry 2

installation, it is recommended that at least 1 ventilation

tiles per the roof surface.
