The inverted roof, a flat roof construction, stands out with its main feature: the thermal insulation is placed above the Polymer Modified Neuchâtel Mastic Asphalt. This design ensures that the dew point is taken outside the building, preventing condensation from forming inside the roof structure.
For the finishing surface, various options are available, including gravelled or pebbled roofs, paved terrace roofs, green roofs, or even a combination that may include planters. The flexibility in choosing the deck or ballast type allows for diverse and customizable roofing solutions.
