The companies Onduline and Tejas Verea explain through a virtual 3D recreation the installation process of efficient and micro-ventilated roofs with Verea ‘S’ mixed ceramic tiles and Onduline Low Tile slabs, using the Verea System approved roof installation system.

An audiovisual rendering shows the details of the installation, insulation and waterproofing of the roof, as well as each of the critical points of the roof, such as the eaves, the overhangs or the joints at the ridge.
