A Protan vacuum roof system uses negative pressure beneath the membrane to secure it firmly to an airtight, load-bearing substrate without mechanical fasteners. Wind acting on the roof surface creates suction that holds the membrane in place, resulting in a clean roof with no visible fixings, minimal penetrations of the vapour control layer, and high levels of airtightness 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.
