Why Choose a Protan Vacuum Roof?

• Unique Solution: No fasteners on the roof surface – wind power does the job!
• Extreme Weather Resistance: Perfect for harsh weather areas with strong wind.
• Intact Vapour Barrier: No holes in the vapor barrier, thanks to the absence of fasteners.
• Quick and Easy Installation: The roofing membrane is laid in wide strips and sealed against parapets and penetrations.
• Efficient Construction Process: Protan vacuum roof ensures rapid installation and a quick construction process.
• Perfect for Passive Houses: Fewer welding joints and high airtightness make it ideal for buildings with strict airtightness requirements.
• Ideal for Humid Environments: Perfect for swimming pools, breweries, and other buildings with high humidity.
• Natural Ventilation: The vacuum roof helps to ventilate trapped moisture in the roof construction.
• No Drilling Noise: Perfect for office buildings, hospitals, schools, and other institutions where noise must be avoided.

How It Works

As the wind blows, the air in the space between the Protan membrane and the air-tight structural roof deck is sucked out of the system through the Protan vacuum vents’ one-way air valves. The vacuum that is created holds the Protan membrane in place, so mechanical restraint is only required around the roof perimeter and penetrations.With millions of square meters installed across Europe, you can trust our expertise. Protan vacuum roofs are suitable for both new construction and rehabilitation and require a tight layer in the substructure. We use Protan SE or Protan EX as roofing membranes and install vacuum valves to drain overpressure.
