A Protan vacuum roof system is based on the principle of negative pressure within the cavity between the roofing membrane and an airtight, load-bearing substrate. When wind acts on the roof surface, it generates suction beneath the membrane, securing it firmly in place without the need for mechanical fasteners.
This approach results in a clean roof surface without visible fixings, minimises penetrations of the vapour control layer, and contributes to high levels of air-tightness and moisture control.

Drilling noise can be a problem with roof renovation. Installing a Protan vacuum roof system reduces the amount of noise during installation, which is a major benefit for those using buildings such as offices, hospitals, schools and other institutions.
Many millions of square metres of Protan vacuum roofing have been installed all over Europe. We use our extensive expertise and experience to calculate the ideal solution for our clients. The vacuum roof system is suitable to both new builds and the refurbishment of roofs. The solution requires an air tight layer in the substructure. It is therefore well suited to the refurbishment, where the existing roofing and method of attachments are assessed as being in good condition.
Depending on the substrate, Protan SE or Protan EX is used as the roof covering for vacuum roof system. Vacuum vents are installed on the roof to release the excess pressure that is created between the roof covering and the airtight substrate. The vents are located on the roof surface in places where the negative pressure is greatest, particularly around the corners and edges.
