Protan Vacuum System

Why Choose a Vacuum System

1. Rapid Installation & Speedy Construction
   The system minimises mechanical fixings and simplifies detailing, meaning fewer hours on site and faster hand-over.
   
   
2. No Roof Surface Fixings
   Because the membrane is held in place via vacuum/suction rather than mechanical fixings, there’s no need to penetrate the vapour-control layer or structure. There is no need for fasteners on the roof surface, so the vapour control layer is not punctured.
   
   
3. Excellent Air-tightness & Moisture Control
   The system is well suited for buildings with strict air-tightness requirements (e.g., passive houses) and for humid indoor environments (e.g., swimming pools, breweries).
   
   
4. Ideal for Refurbishment and Harsh Climates
   Whether a new build or roof renovation, the vacuum roof system adapts. Especially suited for regions exposed to high wind loads.
   
   
5. Noise-Reduced Installation
   Minimal drilling and mechanical fixings reduce installation noise — beneficial for noise sensitive environments like hospitals, schools, offices.
   
   
6. Sustainable & Low Carbon Footprint Materials
   The manufacturer notes their products have among the lowest carbon footprints in the roofing-membrane category.

Noise-free installation

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.

How it works

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.
