WHY DRY INSTALLATION?

Dry installation has significant advantages over conventional installation, as well as improving the performance of the roof during both
summer and winter.

To ensure that the roof is installed correctly, air must circulate continuously in the space under the roof tiles. This micro-ventilation
will allow air to enter via the eave lines and leave through the ridge lines, increasing through the use of ventilation roof tiles distributed

along the roof.

During the summer this air chamber will reduce the amount of heat received by the support for the roof tile and, therefore, the heat

transferred into the building, reducing air conditioning costs. In winter, indoor ventilation will prevent condensation from forming on
the materials used to build up the roof (roof tiles, insulation, support, etc.), as they harm their durability. Furthermore, this condensa-
tion can affect the comfort of the building, producing moisture that is conducive to the formation of moss and bacteria that reduce

the quality of the air inside.

With regards fittings, the use of mortar is not recommended due to its poor reaction with ceramics and the rigidity of joints. Roof tiles

should be fixed mechanically or with adhesives made specifically for roof tiles, since these give the materials the necessary room to
allow for the movements caused by expansion and changes in temperature.

ROOF SLOPES

Each roof must be planned taking into account where it should be built and the length of the deck, in accordance with the technical
standards applicable in each territory. It is for this reason that for each area and location, must take into account of the minimum
slopes for installation and the roof length.
