PROVAC - the Prefabricated Vacuum Roofing System
PROVAC, Protan’s unique single ply roofing system, utilises wind forces present in the environment to provide durability and protection even in extreme conditions. Since the installation of the first Norwegian vacuum roof in 1985, the system has been adopted for over 2 million square metres of roofs throughout Europe.
PROVAC works by loose laying the Protan SE membrane onto the roof with fastening only around the perimeters and penetrations. Strategically located vents within the design act as pressure release valves. The stronger the wind forces, the better the system works. The system is suitable for both new roofs and refurbishments, in particular those with structural concrete or concrete slab decks.
