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
and ridge line. To this end, a space must be left between 6
the roof tiles and the support. As a result, eave lines,

roof tiles per the roof.
