“Don’t knock the weather. If it didn’t change once in a while, nine tenths of people couldn’t start a conversation.” The windier it is, the better the system works! Protan Vacuum Roofing is a unique system that does not require fasteners or adhesives to be used on the field area. The wind forces create a vacuum effect that sucks the membrane firmly onto the roof structure. Unique system which does not require fasteners When the vacuum roof is exposed to wind forces, negative pressure is generated in the layer between the membrane and an airtight, load-bearing substrate. This makes our vacuum roofing ideal in harsh climates. No fasteners need to be used on the field area, so the vapour control layer is not punctured. The membrane is loose laid in 1, 2 or 4 metre widths, then air sealed against the parapet and around any penetrations. No noise during installation Drilling noise can be a problem when renovating roofs. Fitting a Protan Vacuum Roof System reduces installation noise significantly, a major benefit for users of buildings such as offices, hospitals, schools and other institutions. Rapid installation Protan Vacuum Roof System guarantees rapid installation and a speedy building process. The solution has very few joints and is a perfect match for projects with strict air tightness requirements, such as passive houses. Our vacuum roofing system is also ideal for buildings with high humidity, such as swimming pools, breweries, etc. This is how it works Protan’s vacuum system is based on the principle of anchoring the membrane by creating negative pressure in the layer between the membrane and the airtight substrate when exposed to wind loading. The negative pressure causes the membrane to be held down against the substrate, and the load is transferred downwards to the underlying supporting structure. The stronger the wind, the better the system works. The Protan vacuum system has been verified and approved by the Sintef Building and Research Institute (TG 2281) & BBA 98/3459.
