VEREA SYSTEM®

The VEREA SYSTEM® roofing system consists of a unidirectional hollow-core slab with a 15 mm interior gypsum plaster layer, on which a 120 mm PIR insulation (0.027 W/m·K) and a 19 mm thick wooden board are placed. On top of the wooden board, the Verea system is installed, which includes a 140 g/m² vapor barrier (Sd>2m), an Onduline BT150Plus bituminous corrugated sheet, and Verea curved ceramic tiles in sizes 40x20, 45x20, and 50x21, and Spanish S tiles, along with their special components. The installation of the corrugated sheet and ceramic tiles, as well as the execution of specific roofing details (eaves, side trims, ridges, and valleys), must be carried out following the guidelines of Technical Suitability Document No. 622p/22. As a multilayer system, the VEREA SYSTEM® ensures both thermal insulation and waterproofing of the roof, reducing construction time and minimizing execution errors on-site. Thanks to the ventilated layer created on the exterior side of the thermal insulation, as well as the micro-ventilation beneath the tiles, the system enhances the hygrothermal performance of the roof and the durability of all ceramic components, while also ensuring the stability of all roofing elements even under the most adverse climatic conditions.
