Ridge cap ROLL-TECH

The best choice for a cool roof in summer and a dry roof in winter! ROLL-tech, analysed by Riwega experts especially for use with curved tiles and roof tiles, is manufactured by a system designed by engineers from H+O, a specialist German company controlled by Riwega srl. ROLL-tech is composed on the outside of two coloured aluminium strips spread on the underside with a strip of butyl glue and attached at its central section to a breathable* polypropylene netting. Waterproof (against infiltrations of water, not heavy rain). A special glue and a seam with an anti-UV yarn guarantee the joint between strips and netting. The central part of the netting is covered by a reinforced fabric to ensure proper, quick and practical laying that is also mechanically durable over time. *Each side of the netting guarantees consistency with a free passage of air of approximately 1.45 cm thickness; in this way the Venturi effect is triggered with a ventilation chamber of between 4 and 8 cm.
