Venti-tech is an under-ridge element made of rigid PVC, with side brushes, that can be laid on any type of roof covering but is ideal for roofs laid with curved tiles. Thanks to the wide range of widths available for the PVC element, the height of the brushes and the colours available, Ventitech combines with all types of ridges and adapts to all colours of roof. The perforations ensure a passage of air in excess of 120 cm2/m in accordance with DIN 4108/3 standard. The UV stabilized anti-rain brush protects the area under the roof from rain and prevents access by birds and rodents.
