Working with the forces of nature
The membrane is installed on the roof with specially designed vacuum air vents fastened only around the perimeters and penetrations. The stronger the wind forces, the better the system works.
Traditionally roof coverings are adhered, ballasted or mechanical fastened to the base to resist wind uplift. Based on a proven scientific principle Protan has developed its Vacuum Roofing System using a greater understanding of the way in which wind-forces act upon a building. Since the early installation of the vacuum roof of the Norwegian Building Research Institute in Trondheim, Norway, the system has been adopted for many projects around Europe.
For the vacuum roofing system, Protan has developed the
Protan SE range.
This system is especially suitable:
-
When the use of fasteners is prohibited or undesirable
-
When the base is not suited to the use of traditional methods
-
When renovating sound surfaces
Cost saving is possible, depending upon the geometry of the building. Often a good alternative when speed of application is critical. The system introduces controlled airflow beneath the membrane through specially designed air valves. However due to the nature of the design principle, the substrate must be airtight.
In all cases, consult Protan Technical Services Department.
