The upgrade of a building’s energy efficiency leads to the reduction in heating and cooling costs. Inverted insulation and waterproofing covered with concrete screed system provides complete waterproofing and insulation and at the same time trafficability in the roof. ALCHIMICA’s solution based on the HYPERDESMO® – PB -2K certified polyurethane membrane offers a complete solution in the roof as it offers a seamless, easy to install with a root resistant properties application.
For better system results, the installation of a extruded polystyrene is needed because it withstands greater stresses, has a high thermal efficiency standard and it does not allow the penetration of moisture, achieving absolute waterproofing.
