Our teams completed the insulation and waterproofing of the roofs for the extensions of Webasto Luxembourg S.A. in Grevenmacher. The two extensions have respective surface areas of 10,000 m² and 2,200 m².
A 150 mm thick PIR insulation, covered with Sika 15G waterproofing, was chosen to ensure the performance required by the client for the larger section.
An aluminum vapor barrier and a TPO Sika waterproofing membrane covered with extruded polystyrene insulation and a gravel ballast (yet to be implemented for the latter two) were chosen for the second section due to the specific activity of this part of the building.
