Protan vacuum roof system

Protan Vacuum Roofing is a unique system that does not require fasteners or adhesives to be used on the roof surface. The wind forces create a vacuum effect that sucks the membrane firmly onto the roof structure. The windier it is, the better the system works.

The unique Protan Vacuum system uses wind forces present in the environment to hold the Protan membrane in place, thus providing durability and protection even in the most extreme conditions.

Since the installation of the frst Protan Vacuum system in Norway in 1985, the system has been installed on over 2,000,000m² of roofs throughout Europe.

The Protan Vacuum system works by loose-laying Protan SE, EX, or EXG membrane on the roof, with fxings around penetrations and the roof perimeter only. Strategically located Protan vacuum vents installed within the system act as pressure-release valves, which allow controlled air flow through and out of the system through specially designed air valves – the stronger the wind forces, the better the system works.

The Protan Vacuum system is suitable for new roofs and refurbished roofs, especially those with concrete roof decks.

Two key components of the Protan Vacuum system are an air-tight roof deck and a load-bearing vapour control layer.
