PVC single-ply membrane roof system for warm roof constructions that requires no adhesives or fasteners - just the power of the wind.
The Protan Vacuum System uses one-way air vents to suck the air out of the space between the Protan membrane and the substrate. This creates a vacuum within the space, which sucks the Protan membrane down to the substrate and holds it in place without the need for mechanical fixings or adhesives. The system is suitable for both new-build and refurbishment projects. The roof substrate and the membrane’s perimeter fasteners must be airtight. In order to assess the suitability of a particular building, it must be inspected and evaluated by a Protan Technical Services Manager.

Accessories: A wide range of accessories is available, including prefabricated components and Protan Laminated Metal for forming flashings and perimeter details. Environment: The system is fully recyclable; there is no contamination because no adhesives or solvents are used during installation. Additionally, the system can be thermally upgraded with ease, as fixings are only used around the perimeter and penetrations. Durability: Accelerated weathering tests and performance in service confirm that satisfactory retention of physical properties is achieved. All available evidence indicates that Protan SE membranes should have a life in excess of 30 years. Refer to BBA certificate No 98/3459. Technical approval: Further information about the Protan Vacuum roof system can be found in the NBI Technical Approval No 2281. Maintenance and inspection: In accordance with BS 6229, Protan recommends that the roof be inspected in spring and autumn for cleaning of gutters; ensuring outlets are clear and freeflowing and without evidence of damage. Special attention should be paid to the Protan Vacuum Vents. |
